Approaches to Engaging Men During Primary Healthcare Encounters: A scoping review.

Gender-responsive healthcare is critical to advancing men's health given that masculinities intersect with other social determinants to impact help-seeking, engagement with primary healthcare, and patient outcomes. A scoping review was undertaken with the aim to synthesize gender-responsive approaches used by healthcare providers (HCPs) to engage men with primary healthcare. MEDLINE, PubMed, CINAHL, and PsycINFO databases were searched for articles published between 2000 and February 2024. Titles and abstracts for 15,659 citations were reviewed, and 97 articles met the inclusion criteria. Data were extracted and analyzed thematically. Thirty-three approaches were synthesized from across counseling/psychology, general practice, social work, nursing, psychiatry, pharmacy, and unspecified primary healthcare settings. These were organized into three interrelated themes: (a) tailoring communication to reach men; (b) purposefully structuring treatment to meet men's health needs, and (c) centering the therapeutic alliance to retain men in care. Strength-based and asset-building approaches focused on reading and responding to a diversity of masculinities was reinforced across the three findings. While these approaches are recommended for the judicious integration into health practitioner education and practice, this review highlighted that the evidence remains underdeveloped, particularly for men who experience health inequities. Critical priorities for further research include intersectional considerations and operationalizing gender-responsive healthcare approaches for men and its outcomes, particularly at first point-of-contact encounters.

"I'd have no idea how to go about this " - a survey of Australian medical students' perspectives on their men's health education.

BACKGROUND: While there have been calls over the last 15 years for the inclusion of training in sex and gender-based medicine in medical school curricula and to sustain such improvements through a more gender responsive health system, little progress has been made. A related objective of the Australian National Men's Health Strategy (2020-30) is to improve practitioner core learning competencies in men's health as a critical step to reducing the burden of disease in men and disparities between men in health care access and outcomes. The aim of this study was therefore to obtain Australian medical student perspectives on the extent to which men's health and sex and gender-based medicine education is delivered in their curricula, their preparedness for engaging with men in clinical practice, and the men's health content they would have found useful during their training. METHODS: Eighty-three students (48% male) from 17 accredited medical schools, and in at least their fourth year of training, completed an online survey. The survey was co-designed by a multidisciplinary team of men's health researchers and clinicians, alongside a student representative. A mix of quantitative and qualitative survey items inquired about students' preparedness for men's health clinical practice, and coverage of men's health and sex- and gender-based medicine in their curricula. RESULTS: Most students reported minimal to no men's health coverage in their medical school education (65%). While few were offered optional men's health units (10.5%), the majority would have liked more formal training on the topic (78%). Accompanying qualitative findings substantiated a lack of preparedness among medical students to engage male patients, likely stemming from minimal coverage of men's health in their medical education. CONCLUSIONS: Australian medical students may feel underprepared for contemporary men's health clinical practice, as well as, albeit to a lesser extent, women's health clinical practice. There is a clear need and desire amongst medical students to enhance curricula with sex and gender-based medicine training.

Pulmonary endemic mycoses.

While rare, the likelihood of encountering a case of a pulmonary endemic mycosis (PEM) in the UK is increasing. Diagnosis may be challenging, often leading to considerable delay to appropriate treatment. Clinical suspicion must be present for respiratory disease, particularly in the immunocompromised or in those not responding to empiric treatment approaches, and an extended travel history should be obtained. This article summarises the epidemiology of PEM, key clinical features, diagnostic strategies and management.

A randomized wait-list controlled trial of Men in Mind: Enhancing mental health practitioners' self-rated clinical competencies to work with men.

Improved engagement of men in psychotherapy is an essential element in improving male health outcomes. This trial examined whether the Men in Mind intervention improved practitioners' self-rated clinical competencies to engage and respond to male clients in therapy. A parallel, single-blind, wait-list randomized controlled trial was conducted with Australian-based mental health practitioners, currently administering psychotherapy to males, fluent in English, and not currently completing their undergraduate degree. Participants were randomly assigned 1:1, through variable-sized blocks stratified by gender, to either the intervention (Men in Mind) or wait-list control. Men in Mind was offered as a self-led 6-week, five-module online program to upskill practitioners to engage and respond to male clients. The primary outcome was self-reported competency in engaging men in psychotherapy, measured by the Engaging Men in Therapy Scale (EMITS) at 6 weeks. All analyses were by intention-to-treat. Between January 16 and March 17, 2022, 587 participants were randomly assigned to the intervention (n = 300) or wait-list control (n = 287). In total, 492 (84%) participants completed the primary endpoint assessment at 6 weeks. Men in Mind demonstrated a large effect of improved EMITS scores compared to the control group (d = 2.63, 95% CI [2.39, 2.87], p < .001). Men in Mind was effective at increasing mental health practitioners' self-reported efficacy to work with men, which is potentially a key change mechanism in their ability to improve health outcomes for male clients. A limitation of the trial was the use of a bespoke, self-reported primary outcome, while a strength was the gender-responsive intervention design.

Supporting Clinical Competencies in Men's Mental Health Using the Men in Mind Practitioner Training Program: User Experience Study.

BACKGROUND: Engaging men in psychotherapy is essential in male suicide prevention efforts, yet to date, efforts to upskill mental health practitioners in delivering gender-sensitized therapy for men have been lacking. To address this, we developed Men in Mind, an e-learning training program designed to upskill mental health practitioners in engaging men in therapy. OBJECTIVE: This study involves an in-depth analysis of the user experience of the Men in Mind intervention, assessed as part of a randomized controlled trial of the efficacy of the intervention. METHODS: Following completion of the intervention, participants provided qualitative (n=392) and quantitative (n=395) user experience feedback, focused on successes and suggested improvements to the intervention and improvements to their confidence in delivering therapy with specific subpopulations of male clients. We also assessed practitioner learning goals (n=242) and explored the extent to which participants had achieved these goals at follow-up. RESULTS: Participants valued the inclusion of video demonstrations of skills in action alongside the range of evidence-based content dedicated to improving their insight into the engagement of men in therapy. Suggested improvements most commonly reflected the desire for more or more diverse content, alongside the necessary adaptations to improve the learning and user experience. Participants also commonly reported improved confidence in assisting men with difficulty articulating their emotions in therapy and suicidal men. CONCLUSIONS: The evidence obtained from this study aids in plans to scale Men in Mind and informs the future development of practitioner training interventions in men's mental health.

"Hey Amir, How Are You REALLY Doing?": Participant Perspectives of a Peer-Based Suicide Prevention Campaign for Men.

Suicide is a major public health concern and leading cause of death among men in Canada. This study reports the feasibility and acceptability of Buddy Up, a peer-based suicide prevention campaign for men. A mixed-methods approach was used to analyze respondent survey questionnaires (n = 48) and individual participant interviews (n = 19) collected from campaign users. Survey respondents reported that they enjoyed their involvement in the campaign (92%), were more confident to talk with men about mental health and suicide (95%), and would recommend Buddy Up to others (95%). Qualitative interviews were thematically analyzed to develop three inductively derived themes: (a) Engaging men with relatable masculine content and design: "Buddy Up really spoke to them in their language," highlighting the importance of understanding and working with gendered practices and motivations to legitimize and motivate involvement in suicide prevention; (b) Leveraging campaign participation to initiate conversations and promote mental health: "It gives men language and license to start asking questions," revealing ways in which participants utilized Buddy Up to negotiate and norm checking-in to promote men's mental health; and (c) Driving new masculine cultures: "We start every meeting with a mental health moment," identifying how participants fostered healthy milieus for disclosing mental health challenges with teamwork and preventive action under the banner of Buddy Up. The study findings support the feasibility of Buddy Up and highlight the acceptability of peer-based approaches to mental health promotion. The findings can also empirically guide future efforts for systematically building men's peer-based suicide prevention programs.

High-Throughput IgG Reformatting and Expression Using Hybrid Secretion Signals and InTag Positive Selection Technology.

We have previously published protocols for high-throughput IgG reformatting and expression, that enable rapid reformatting of phage-displayed antibody Fab fragments into a single dual expression vector for full IgG expression in Expi293F cells (Chen et al. Nucleic Acids Res 42:e26, 2014; Chen et al. Methods in Molecular Biology, vol 1701, 2018). However, when working with phage clones from a naïve library containing highly diverse N-terminal sequences, where the 5' PCR primers bind, the PCR step can become cumbersome. To overcome this limitation, we have investigated and found that the C-terminal 7 amino acid residues of the human antibody VH1 secretion signal can be replaced with those from ompA or pelB bacterial signals to form hybrid signal sequences that can drive strong IgG expression in Expi293F cells. The use of such hybrid signals allows any Fab fragment in the library to be amplified and cloned into the IgG expression vector using only a single 5' PCR primer targeting the bacterial secretion signal of the light or heavy chain, thus dramatically simplifying the IgG reformatting workflow.

The Impact of the COVID-19 Pandemic on the Experiences and Operations of Sponsors of the Summer Food Service Program in Maryland, USA: A Multiphase Mixed Methods Study.

During the COVID-19 pandemic, the Summer Food Service Program (SFSP) was allowed to operate in untraditional non-summer months to ensure children did not lose access to free and reduced-priced nutritious meals when schools were mandated to close in the United States. This study assessed the impact of the pandemic on the operations and experiences of Summer Food Service Program (SFSP) sponsors in the state of Maryland during the COVID-19 pandemic in 2020 (Phase I) and 2021 (Phase II). This study used a multiphase explanatory sequential mixed methods design with qualitative prioritization. Maryland SFSP sponsors completed an online survey (Phase I: n = 27, Phase II: n = 30), and semi-structured in-depth interviews were conducted with a subset of sponsors who completed the survey (Phase I: n = 12, Phase II: n = 7). Inductive and deductive analyses were used for qualitative data, and descriptive statistics were used for quantitative data. The COVID-19 pandemic caused SFSP sponsors to change their operations. Sponsors were primarily concerned about staff safety/burnout and decreased participation. Sponsors perceived waivers implemented by the United States Department of Agriculture to be crucial in enabling them to serve meals to children during the pandemic. The findings from our study support advocacy efforts to permanently implement waivers and provide free school meals for all children.

Why do queer men experience negative body image? A narrative review and testable stigma model.

Queer men (i.e., men who are not heterosexual; sexual minority men) are disproportionately affected by negative body image - they experience greater body dissatisfaction are more likely to develop eating disorders than heterosexual men. While existing literature has examined individual-level predictors of negative body image for queer men, less is known about why queer men as a group are disproportionately affected by negative body image. By synthesising existing theoretical frameworks, research, policy, and media reporting, this narrative review moves towards an understanding of systemic-level negative body image for queer men. Through the lens of hegemonic masculinity, we explain how systemic experiences of stigma work to inform unattainable appearance standards for queer men, and how these standards then contribute to pervasive negative body image concerns among this community. Next, we describe how systemic stigma works to exacerbate negative health outcomes for queer men with body image concerns. Finally, we present a synthesized model of the processes outlined in this review, articulate testable predictions for future studies, and describe practical implications that could be widely employed to improve body image for queer men. Our review is the first to propose a comprehensive explanation of systemic negative body image for queer men.

Suicidal ideation in men during COVID-19: an examination of protective factors.

BACKGROUND: Men account for three-quarters of all suicide deaths in many Western nations including Australia. Whilst extensive research has examined risk factors for suicidal ideation and behaviour in men, protective factors remain underexplored, particularly social support, resilience and coping behaviours. Such factors are important to examine particularly in the context of COVID-19, where enforced isolation (among other negative lifestyle effects) has created widespread risk for the development of suicidal ideation. This mixed-methods study aimed to examine associations of various protective factors with suicidal ideation in men, using data from an online survey conducted during the COVID-19 pandemic. In addition, we aimed to qualitatively investigate men's self-reported protective strategies when experiencing suicidal thoughts and behaviour. METHODS: A convenience sample of 700 men (age M = 50.3 years; SD = 15.2 years) responded to an online survey including quantitative measures of suicidal ideation, planning and attempt, alongside employment and relationship status, coping, social support, resilience, and a qualitative free-text item gauging men's self-reported protective strategies. Multinomial logistic regression was applied to compare odds of sub-categories of suicide risk (ideation; planning) according to protective factors. Qualitative responses were analysed via thematic analysis. RESULTS: Men in a relationship, and those lower in emotion-focused and avoidant coping reported lower odds of suicidal ideation. Maintaining employment throughout the pandemic was protective against suicidal ideation and planning; as was greater perceived social support from friends. Greater self-reported resilience was protective against suicidal ideation and planning. Qualitative analyses led to the development of two themes: coping and connecting, reflecting men's intra- and interpersonal management strategies; and sustaining selflessness, where men's imaginings of the collateral damage of their suicidal behaviour was protective against action on suicidal thoughts or plans. CONCLUSIONS: Findings of this study speak to the nuanced roles of interpersonal connections, resilience and coping behaviours in protecting against suicidal ideation and planning in men. In addition, qualitative insights further cement men's identification with familial protector and/or provider roles as protective against suicidal action.

HDX-MS study on garadacimab binding to activated FXII reveals potential binding interfaces through differential solvent exposure.

Hageman factor (FXII) is an essential component in the intrinsic coagulation cascade and a therapeutic target for the prophylactic treatment of hereditary angioedema (HAE). CSL312 (garadacimab) is a novel high-affinity human antibody capable of blocking activated FXII activity that is currently undergoing Phase 3 clinical trials in HAE. Structural studies using hydrogen/deuterium exchange coupled to mass spectrometry revealed evidence of interaction between the antibody and regions surrounding the S1 specificity pocket of FXII, including the 99-loop, 140-loop, 180-loop, and neighboring regions. We propose complementarity-determining regions (CDRs) in heavy-chain CDR2 and CDR3 as potential paratopes on garadacimab, and the 99-loop, 140-loop, 180-loop, and 220-loop as binding sites on the beta chain of activated FXII (ß-FXIIa).

"I could hang up if the practitioner was a prat": Australian men's feedback on telemental healthcare during COVID-19.

The COVID-19 pandemic restrictions, uncertainties and management inconsistencies have been implicated in men's rising distress levels, which in turn have somewhat normed the uptake of telemental healthcare services (i.e., phone and/or video-conference-based therapy). Given past evidence of poor engagement with telemental health among men, this mixed-methods study examined Australian men's use of, and experiences with telemental health services relative to face-to-face care during the pandemic. A community sample of Australian-based men (N = 387; age M = 47.5 years, SD = 15.0 years) were recruited via Facebook advertising, and completed an online survey comprising quantitative items and open-response qualitative questions with the aim of better understanding men's experiences with telemental healthcare services. In total, 62.3% (n = 241) of participants reported experience with telemental health, and regression analyses revealed those who engaged with telemental health were on average younger, more likely to be gay and university educated. Men who had used telemental health were, on average, more satisfied with their therapy experience than those who had face-to-face therapy. Among those who had telemental healthcare, marginally lower satisfaction was observed among regional/rural based relative to urban men, and those who had to wait longer than 2 months to commence therapy. Qualitative findings highlighted positive aspects of telemental healthcare including comfort with accessing therapy from familiar home environments and the convenience and accessibility of telemental health alongside competing commitments and COVID-19 restrictions. Conversely, drawbacks included technical limitations such as crosstalk impeding therapeutic progress, disconnects and audio-visual lag-times and the 'impersonal' nature of telemental healthcare services. Findings broadly signal COVID-19 induced shifts norming of the use of virtual therapy services, with clear scope for improvement in the delivery of therapeutic practice using digital modalities, especially among help-seeking men.

Male-Type Depression Mediates the Relationship between Avoidant Coping and Suicidal Ideation in Men.

Despite known links between men's avoidant coping behaviours (e.g., distraction, denial, substance use) and suicide risk, little research has explored the mechanisms underpinning this relationship. This study sought to examine whether male-type depression symptoms (e.g., anger, aggression, emotion suppression), assessed by the Male Depression Risk Scale, mediate the association between avoidant coping and suicide/self-harm ideation in men. Data were drawn from an online survey of a community sample of 606 Australian men (M age = 50.11 years; SD = 15.00), conducted during the COVID-19 pandemic. Mediation analyses were applied to examine the effect of male-type depression on the association between avoidant coping and suicidal/self-harm ideation, controlling for age, resilience and the experience of two psychosocial stressors during the COVID-19 pandemic (financial stress and government restrictions). Avoidant coping was associated with suicidal/self-harm ideation, r = 0.45, p < 0.001. Results supported a mediating role of male-type depression symptoms in this relationship, R2= 0.29, PM = 0.36, p < 0.001, underscoring the importance of screening for male-type depression symptoms to better identify men at risk of suicidal/self-harm ideation. Results also suggest a need to support men to develop effective coping strategies, particularly in the context of common psychosocial stressors experienced during the COVID-19 pandemic and beyond.

"I Called When I Was at My Lowest": Australian Men's Experiences of Crisis Helplines.

Background: Helplines are an accessible form of support for people struggling with difficulties in their lives and are key services in suicide prevention and intervention. Men's experiences of telephone helplines are not well understood, despite high male suicide rates. Methods: We conducted an online cross-sectional survey with N = 684 Australian men (aged 17-83 years, M = 50.13) using open- and closed-ended questions about their experiences of helplines during the COVID-19 pandemic. Descriptive statistics were analysed to investigate differences between men using and not using helplines. Qualitative responses were analysed using thematic analysis. Results: Within the sample, 100 men (14.6%) had used a helpline service. Men using helplines were more likely to be unemployed and in younger age brackets than those not using helplines. They were also more likely to report experiencing stressors related to COVID-19, including financial stress and job loss, perceived impact on mental health and relationship breakdown. Qualitative analysis indicated varied experiences of helplines, with men shedding light on how their interaction with a counsellor, the structure of services and their expectations of the service impacted their experience. Conclusions: Further in-depth qualitative enquiry in this space is required, with the objective of understanding how helpline services may seek to better engage with male callers.

Protocol for a randomized controlled trial of the Men in Mind training for mental health practitioners to enhance their clinical competencies for working with male clients.

BACKGROUND: Although the proportion of men seeking professional mental health care has risen over the past two decades, on average, men continue to attend fewer sessions of psychotherapy and are more likely to drop out of treatment prematurely compared to women. Men account for three-quarters of suicide deaths; furthermore, over half of the males who die by suicide have engaged with mental health care in the 12 months prior to their death. These findings highlight a need to equip mental health practitioners with skills to improve male clients' engagement and mental health outcomes. This article reports the protocol for a randomized controlled trial of Men in Mind, a self-paced online training program purpose-built to advance the clinical competencies of practitioners who provide psychotherapy to male clients. METHODS: A randomized controlled trial with two parallel groups will be conducted. Participating practitioners will be randomly allocated, on a 1:1 basis, to the intervention group (Men in Mind training) or a waitlist control group. The primary outcome, efficacy of the training, will be evaluated by pre- to post-training (T1 to T2) changes in scores on the Engaging Men in Therapy Scale (EMITS) in the intervention group, relative to the control group. DISCUSSION: This trial will provide evidence of the efficacy of Men in Mind training, as an interim step towards adjusting content and delivery of the intervention to maximize the potential for sustaining and scaling. TRIAL REGISTRATION: The trial was registered prospectively with the Australian New Zealand Clinical Trials Registry on 3rd December 2021 (ACTRN12621001669886).

Exploring Teacher and Parent Perspectives on School-Based Masculinities in Relation to Mental Health Promotion.

The capacity for boys' and young men's mental health promotion to act via shifting masculine norms that are linked to poor mental health outcomes, highlights the need to improve the extent to which school-based programs can promote mental health through leveraging more positive embodiments of masculinity. To-date, the perspectives of parents and teachers on such processes are understudied. This qualitative study presents teacher and parent views regarding adolescent masculinities and avenues for school-based developmental programming for boys and young men. In this study, 16 individual qualitative interviews were undertaken with 10 parents (six females, four males), and six teachers (three females, three males), recruited from an independent all-boys' grammar school in Melbourne, Australia. Thematic analysis of parents' and teachers' perspectives indicated their perception of the role of context-dependent "public" and "private" masculinities, the influence of Australian masculinity norms, and the role of private boys' school cultures in the development of adolescent masculinities. Additionally, strategies for development encompassed participants' appetite for boys' exposure to positive role models, in addition to consistent and relevant developmental programming to support positive masculinity development. Findings have implications for efforts to support prosocial masculine identity development via school-based initiatives, as an avenue to promoting mental health of boys and young men.

"Appreciate the Little Things": A Qualitative Survey of Men's Coping Strategies and Mental Health Impacts During the COVID-19 Pandemic.

The COVID-19 pandemic has presented a suite of circumstances that will simultaneously affect mental health and mobilize coping strategies in response. Building on a lack of research specifically exploring men's mental health impacts during the COVID-19 pandemic, this study presents the results of a qualitative survey exploring men's self-reported aspects of the pandemic giving rise to mental health challenges, alongside their diverse coping strategies applied during this time. The sample comprised 555 men from North America (age M = 38.8 years; SD = 13.5 years), who participated via an online survey with two open-ended qualitative questions assessing, respectively, the aspects of the pandemic affecting their mental health, and the strategies used to manage these challenges. Free-text responses were coded using inductive content analysis. Results pertaining to the mental health impacts of COVID-19 were categorized into two overarching themes: far-reaching ramifications of COVID-19 encompassing consequences for lifestyle, work, and functioning, alongside novel anxieties related to health risks and daily uncertainty. In addition, coping strategies reported were categorized into two broad themes: efforts to avoid, dull or distract oneself from distress, alongside adapting and doing things differently, which encompassed largely approach-oriented efforts to flexibly ameliorate distress. Results signal the far-reaching impacts of COVID-19, alongside profound flexibility and diverse enactments of resilience among men in adapting to unprecedented challenges. Findings have implications for mental health promotion that should aim to leverage men's adaptive coping to encourage opportunities for social connectedness in response to the mental health impacts of the various psychosocial challenges of the COVID-19 pandemic.

Serving Summer Meals During the COVID-19 Pandemic: A Case Study of 2 Summer Food Service Program Sponsors in Maryland.

BACKGROUND: The Summer Food Service Program (SFSP) provides free and nutritious meals to children under age 18 during out-of-school times. During the COVID-19 pandemic, Maryland sponsors served over 9.5 million meals to children through an expanded version of the SFSP. This study aimed to explore and compare the factors that enabled 2 SFSP sponsors in Maryland to dramatically increase meals distribution during the pandemic. METHODS: Sponsors were selected based on their responses in the larger study and demographic characteristics of the area in which they served. Semi-structured in-depth interviews were conducted over Zoom-4 interviews with Sponsor A (3 interviews with the sponsor, 1 interview with their vendor) and 1 interview with Sponsor B. Qualitative data were analyzed inductively and deductively. Participation data from 2019 and 2020 were obtained from the Maryland State Department of Education and analyzed. RESULTS: Despite their differences in organization type and geographic region, they identified similar facilitators to their success-communication with the community and utilization of the United States Department of Agriculture-issued waivers. CONCLUSIONS: Strengthening community communication networks and permanently integrating more flexibility into regulation of the SFSP may increase meals participation during future out-of-school times.

Consuming a Protein and Fiber-Based Supplement Preload Promotes Weight Loss and Alters Metabolic Markers in Overweight Adults in a 12-Week, Randomized, Double-Blind, Placebo-Controlled Trial.

BACKGROUND: Higher protein and fiber diets promote weight management and metabolic health. OBJECTIVES: This study aimed to determine if greater weight loss and positive changes in metabolic outcomes could be achieved with twice-daily consumption of a high-protein and fiber-based multi-ingredient nutritional shake (HPF) compared with an isocaloric low-protein, lower fiber-based placebo (LPF). METHODS: Study procedures were conducted by an independent research organization under clinicaltrials.gov registration NCT03057873. Healthy overweight and obese adults [n = 206; BMI (kg/m2): 27-35; 70% female] were randomly assigned to HPF or LPF. All participants were prescribed an energy-restricted diet (500 kcal/d less than energy needs) and consumed a HPF (17 g protein, 6 g fiber) or LPF (1 g protein, 3 g fiber) shake 30 min before breakfast and lunch for 12 wk. Primary outcomes included body weight and total body fat percentage. Blood samples were collected at days (D) 0, 28, 56, and 84 for secondary analyses related to metabolic markers of health. RESULTS: Although weight loss occurred in both groups, HPF had greater weight loss at D84 compared with LPF (-3.3 kg vs. -1.8 kg, P < 0.05). Percentage body fat decreased in both groups (HPF: -1.33%, LPF: -1.09%; P < 0.001) with no differences between groups. Serum total cholesterol, LDL cholesterol, and oxidized LDL decreased between -5.1% to -8.3%, whereas adiponectin increased over time in both groups; these changes occurred to a greater extent in HPF compared with LPF (all P < 0.05). CONCLUSIONS: A multi-ingredient HPF nutritional supplement shake consumed as a preload before breakfast and lunch positively influenced weight management and metabolic outcomes in overweight adults compared with an LPF placebo. These findings suggest that specific nutrient factors (i.e., potentially including protein, fiber, and bioactive content) other than calorie reduction alone influence the success of a weight-loss regimen. This trial was registered at www.clinicaltrials.gov as NCT03057873.
