Alternate-day fasting has become increasingly popular, yet, to date, no long-term randomized clinical trials have evaluated its efficacy.To compare the effects of alternate-day vs daily calorie restriction on weight loss, maintenance, and risk indicators for cardiovascular disease.A single-center trial obese adults (18 64 years age; mean body mass index, 34) was conducted between October 1, 2011, January 15, 2015, at an academic institution in Chicago, Illinois.Participants were 1 3 groups...
Abstract Recent anecdotal and scientific reports have provided evidence of a link between COVID-19 chemosensory impairments, such as anosmia. However, these downplayed or failed to distinguish potential effects on taste, ignored chemesthesis, generally lacked quantitative measurements. Here, we report the development, implementation, initial results multilingual, international questionnaire assess self-reported quantity quality perception in 3 distinct modalities (smell, chemesthesis) before...
Alternate day fasting (ADF; ad libitum “feed day”, alternated with 25% energy intake “fast day”), is effective for weight loss and cardio-protection in obese individuals. Whether these effects occur normal overweight individuals remains unknown. This study examined the effect of ADF on body coronary heart disease risk non-obese subjects. Thirty-two subjects (BMI 20–29.9 kg/m2) were randomized to either an group or a control 12 weeks. Body decreased (P < 0.001) by 5.2 ± 0.9 kg (6.5 1.0%)...
This study examined whether the combination of alternate day fasting (ADF) plus exercise produces superior changes in body composition and plasma lipid levels when compared to each intervention alone.Obese subjects (n = 64) were randomized 1 4 groups for 12 weeks: 1) (ADF endurance exercise), 2) ADF, 3) exercise, or 4) control.Body weight was reduced (P < 0.05) by 6 ± kg, 3 0 kg combination, groups, respectively. Fat mass waist circumference decreased 0.001), while lean retained group....
As the global coronavirus (COVID-19) pandemic unfolds, more than 90% of U.S. adult residents are confined to their homes, with restaurants, shops, schools, and workplaces shut down prevent disease spread. Although it is a priority mitigate immediate impact, one area great concern long-term effects this on weight management in adults. evident from previous research, small changes body relatively short periods can become permanent lead substantial gain over time ((1)). Considering that current...
Cross-sectional analyses have shown increased obesogenic behaviors and a potential for weight gain during COVID-19 related peak-lockdown (March-May 2020), but longitudinal data are lacking. This study assessed changes in body lifestyle the US adults pandemic.We used Qualtrics survey to collect self-reported on weight, dietary, physical activity, psychological variables (n = 727) (April/May) at post-lockdown (September/October). Peak-lockdown were categorized based magnitude of gained,...
Abstract In a preregistered, cross-sectional study, we investigated whether olfactory loss is reliable predictor of COVID-19 using crowdsourced questionnaire in 23 languages to assess symptoms individuals self-reporting recent respiratory illness. We quantified changes chemosensory abilities during the course illness 0–100 visual analog scales (VAS) for participants reporting positive (C19+; n = 4148) or negative (C19−; 546) laboratory test outcome. Logistic regression models identified...
Background: Sudden smell loss is a specific early symptom of COVID-19, which, prior to the emergence Omicron, had estimated prevalence ~40% 75%. Chemosensory impairments affect physical and mental health, dietary behavior. Thus, it critical understand rate time course recovery. The aim this cohort study was characterize function recovery up 11 months post COVID-19 infection. Methods: This longitudinal survey individuals suffering COVID-19-related assessed disease symptoms gustatory olfactory...
Abstract Background Intermittent fasting (IF; severe restriction 1 d/week) facilitates weight loss and improves coronary heart disease (CHD) risk indicators. The degree to which can be enhanced if IF is combined with calorie (CR) liquid meals, remains unknown. Objective This study examined the effects of plus CR (with or without a diet) on body weight, composition, CHD risk. Methods Obese women (n = 54) were randomized either IFCR-liquid (IFCR-L) IFCR-food based (IFCR-F) diet. trial had two...
Alternate day fasting (ADF; 24-h feeding/24-h 25% energy intake at lunchtime), is effective for weight loss, but diet tolerability questionable. Moving the fast meal to dinnertime, or dividing it into smaller meals, may improve tolerability. Accordingly, this study compared effects of ADF with three times on body and heart disease risk.Obese subjects (n = 74) were randomized 1 3 groups 8 weeks: 1) ADF-L: lunch, 2) ADF-D: dinner, 3) ADF-SM: small meals.Body decreased similarly (P < 0.001) in...
A wealth of rapidly evolving reports suggests that olfaction and taste disturbances may be manifestations the novel COVID-19 pandemic. While otolaryngological societies worldwide have started to consider chemosensory evaluation as a screening tool for infection, true nature relationship between changes in ability is unclear. Our goal with this review provide brief overview published archived literature, well anecdotal social trends related topic up April 29, 2020. We also aim draw parallels...
Obesity is associated with an atherogenic lipid profile characterized by a predominance of small LDL and HDL particles. Weight loss, dietary restriction or exercise, increases particle size. Whether these interventions can augment size in conjunction remains unknown.This study compared the effects alternate day fasting (ADF), calorie (CR), endurance exercise on overweight obese subjects.In 12-week parallel-arm trial, adult subjects (n = 60) were randomized to 1 4 groups: 1) ADF (75% energy...
Abstract Background Alternate day modified fasting (ADMF) is an effective strategy for weight loss in obese adults. Objective The objective of this study was to examine the dietary and physical activity adaptations that occur during short-term ADMF, determine how these modulations affect rate loss. Methods Sixteen subjects (12 women/4 men) completed a 10-week trial consisting 3 phases: 1) 2-week control phase, 2) 4-week ADMF controlled feeding 3) self-selected phase. Results Body decreased (...
Purpose: We investigated the associations between frequency of eating at fast-food, fast-casual, all-you-can-eat, and sit-down restaurants body mass index (BMI) in non-large metro Wisconsin communities. To inform prevention efforts, we also analyzed socioeconomic/environmental nutrition attitudes/behavior variables that may drive frequent away from home. Design: Cross-sectional analysis an ancillary data set Survey Health collected October 2012 February 2013. Setting: Six counties: 1...
Alternate day fasting (ADF; ad libitum intake "feed day" alternated with 75% restriction "fast day"), is effective for weight loss, but the safety of diet has been questioned. Accordingly, this study examined occurrences adverse events and eating disorder symptoms during ADF. Obese subjects (n = 59) participated in an 8-week ADF protocol where food was provided on fast day. Body decreased (P < 0.0001) by 4.2 ± 0.3%. Some reported constipation (17%), water retention (2%), dizziness (<20%),...
The ability of alternate-day fasting (ADF) to modulate adipocyte parameters in a way that is protective against coronary heart disease (CHD) has yet be tested. Accordingly, we examined the effects ADF on adipokine profile, body composition, and CHD risk indicators obese adults. Sixteen subjects (12 women/4 men) participated 10-week trial with three consecutive dietary intervention phases: (i) 2-week baseline control phase, (ii) 4-week controlled feeding (iii) self-selected phase. After 8...
