Food Intake Patterns

Time-restricted eating (TRE) can facilitate weight loss, yet its effect on eating patterns remains unknown. Twenty adults with BMI ≥ 25 kg/m2 underwent a 12-week randomized trial, examining the effect of an 8-h, time-restricted eating intervention on dietary patterns. Oral intake was documented using a smartphone. Dietary patterns, assessed as frequency of eating occasions (EOs) and types of meals/snacks and beverages, were compared between baseline (T0), early-intervention (T1), and end-intervention (T2). At T1 and T2, both groups had less EOs compared to T0, with greater reduction seen in the TRE group (−28%) than the non-TRE group (−12%) at T2 (p = 0.01 vs. non-TRE). Comparing T1 to T0, the TRE group documented less incomplete meals (−32.5%: p = 0.02), high quality snacks (−23.6%: p = 0.03), and low quality snacks (−36.6%: p = 0.004). Comparing T2 to T0, the TRE group documented less incomplete meals (−33.9%: p = 0.03), high quality snacks (−28.1%: p < 0.001) and low quality snacks (−51.2%: p < 0.001). Caffeinated beverage intake was reduced in the TRE group at T1 (−20.2%) and T2 (−28.8%) vs. T0, but remained unaltered in the non-TRE group. By using a smartphone application to document dietary intake, TRE significantly reduced the number of EOs, snacks, and caffeinated beverages, relative to baseline and relative to the non-TRE.

Abstract Weight loss for obese populations has been a challenging subject. There are numerous mobile applications to address weight loss, but the low retention rate is a barrier for the intervention. This is a retrospective study, aiming to investigate the effectiveness of financial incentives to achieve weight loss via a monetary reimbursement model on a smartphone application. Participants voluntarily purchased a 16-week mobile weight loss application program, and those who logged food intake three times a day received monetary reimbursement up to the full amount they initially paid. We analyzed health-related information and logged in-app activities from participants (N = 2,803) including age, sex, weight, food intake, and physical activity on their mobile healthcare application called Noom from January 2017 to April 2019. Analysis of covariance (ANCOVA) was used to compare differences between groups who succeeded and failed at food logging, controlling for baseline BMI. The ANCOVA found that participants who completed the food logging successfully for 16 weeks (N = 1,565) lost significantly more weight than those who failed food logging (N = 1,238, F = 56.0, p < 0.001). In addition, participants who were able to log their food intake successfully exercised more (F = 41.5, p < 0.001), read more in-app articles (F = 120.7, p < 0.001), and consumed more quantity of healthy foods (F = 12.8, p < 0.001). Monetary reimbursement is an effective tool for weight reduction by encouraging participants to monitor their health-related behaviors regularly.

Significant Difference

The prevalence of obesity has been increased in Qatar, with the transition from healthy to unhealthy dietary habits. Behavioral factors that are associated with obesity are, long-term imbalanced energy intake, high screen time, skipping breakfast and physical inactivity. Changes in body composition and percent body fat (PBF) increase the risk of non-communicable disease. This study is the first study conducted in Qatar to investigate the relationship between dietary patterns and body composition among young females at Qatar University. This cross-sectional study consisted of 766 healthy female students Qatari and non-Qatari aged from 18-26 years randomly selected from different colleges at Qatar University. A validate questionnaire was used in order to collect data about healthy and unhealthy dietary patterns. Anthropometric measurements involved body weight, height, waist-to-height ratio (WHtR), waist circumference (WC), body mass index (BMI) and body composition using “Seca285”, “Seca203” and “InbodyBiospace 720”. Dietary patterns were identified by using factor loading. Linear regression was used to estimate confidence intervals and regression coefficient. More than half of the participants had a normal weight (65.1%), whereas 22.8 % and 12.0% were overweight and obese, respectively. Fat mass, BMI and PBF were slightly increased with age, but there was no significant difference. Factor analysis identified two dietary patterns: unhealthy patterns and healthy patterns. The frequent intake of vegetables and fruits was significant among high PBF female students (p=0.045 and p=0.001, respectively). The frequent intake of fast food was higher for overweight female students but there was no significant difference (p=0.289), whereas, the frequent intake of sweetened beverages was associated with higher significant rate of normal weight among female students (p = 0.009). No significant relation was found between dietary patterns, BMI and PBF. In conclusion, body composition is not significantly associated with healthy and unhealthy eating patterns among young females.

Since the outbreak of COVID-19, billions of people have gone into lockdown, facing pandemic related challenges that engender weight gain, especially in the obese. We report the results of an online survey, conducted during Israel’s first quarantine, of 279 adults treated in hospital-based obesity clinics with counseling, medications, surgery, endoscopic procedures, or any combination of these for weight loss. In this study, we assessed the association between changes in dietary and lifestyle habits and body weight, and the benefits of receiving weight management care remotely through telemedicine during lockdown. Compared to patients not receiving obesity care via telemedicine, patients receiving this care were more likely to lose weight (OR, 2.79; p = 0.042) and also to increase participation in exercise (OR, 2.4; p = 0.022). While 40% of respondents reported consuming more sweet or salty processed snacks and 33% reported less vegetables and fruits, 65% reported more homemade foods. At the same time, 40% of respondents reported a reduction in exercise and 52% reported a decline in mood. Alterations in these eating patterns, as well as in exercise habits and mood, were significantly associated with weight changes. This study highlights that lockdown affects health behaviors associated with weight change, and advocates for the use of telemedicine to provide ongoing obesity care during future quarantines in order to promote weight loss and prevent weight gain.

Pragmatic Randomised Controlled Trial

Weight loss is key to controlling the increasing prevalence of metabolic syndrome (MS) and its components, i.e., central obesity, hypertension, prediabetes and dyslipidaemia. The goals of our study were two-fold. First, we characterised the relationships between eating duration, unprocessed and processed food consumption and metabolic health. During 4 weeks of observation, 213 adults used a smartphone application to record food and drink consumption, which was annotated for food processing levels following the NOVA classification. Low consumption of unprocessed food and low physical activity showed significant associations with multiple MS components. Second, in a pragmatic randomised controlled trial, we compared the metabolic benefits of 12 h time-restricted eating (TRE) to standard dietary advice (SDA) in 54 adults with an eating duration > 14 h and at least one MS component. After 6 months, those randomised to TRE lost 1.6% of initial body weight (SD 2.9, p = 0.01), compared to the absence of weight loss with SDA (−1.1%, SD 3.5, p = 0.19). There was no significant difference in weight loss between TRE and SDA (between-group difference −0.88%, 95% confidence interval −3.1 to 1.3, p = 0.43). Our results show the potential of smartphone records to predict metabolic health and highlight that further research is needed to improve individual responses to TRE such as a shorter eating window or its actual clock time.

G Protein Coupled

G protein-coupled receptor 40 (GPR40) partial agonists lower glucose through the potentiation of glucose-stimulated insulin secretion, which is believed to provide significant glucose lowering without the weight gain or hypoglycemic risk associated with exogenous insulin or glucose-independent insulin secretagogues. The class of small-molecule GPR40 modulators, known as AgoPAMs (agonist also capable of acting as positive allosteric modulators), differentiate from partial agonists, binding to a distinct site and functioning as full agonists to stimulate the secretion of both insulin and glucagon-like peptide-1 (GLP-1). Here we show that GPR40 AgoPAMs significantly increase active GLP-1 levels and reduce acute and chronic food intake and body weight in diet-induced obese (DIO) mice. These effects of AgoPAM treatment on food intake are novel and required both GPR40 and GLP-1 receptor signaling pathways, as demonstrated in GPR40 and GLP-1 receptor-null mice. Furthermore, weight loss associated with GPR40 AgoPAMs was accompanied by a significant reduction in gastric motility in these DIO mice. Chronic treatment with a GPR40 AgoPAM, in combination with a dipeptidyl peptidase IV inhibitor, synergistically decreased food intake and body weight in the mouse. The effect of GPR40 AgoPAMs on GLP-1 secretion was recapitulated in lean, healthy rhesus macaque demonstrating that the putative mechanism mediating weight loss translates to higher species. Together, our data indicate effects of AgoPAMs that go beyond glucose lowering previously observed with GPR40 partial agonist treatment with additional potential for weight loss.

The Uk

High yielding cows require high quality diets to sustain milk yields and to minimise weight loss, metabolic disorders and fertility problems. Traditionally, these diets have contained fishmeal and soyabean meal, both widely regarded as good sources of high quality, digestible undegraded protein (DUP). However, there is increasing concern over the sustainability of world fish stocks and the BSE scare has increased public awareness to the extent that feeding animal protein to herbivores may become unacceptable in me future. This in turn has driven up the price of high quality imported vegetable proteins, such as soyabean meal. The aim of this study was to investigate whether fishmeal and soyabean meal could be replaced in the diet of high yielding cows, with protein sources grown in the UKIn a 12 week randomised block design experiment, 60 muciparous Holstein cows, on average 28 days calved at the start of the study, were fed total mixed rations based on grass silage and one of five protein mixtures. These were either 0.5 kg DM fishmeal + 0.7 kg DM soya + 2.5 kg DM rapeseed (PC), 1.3 kg DM soyabean + 2.3 kg DM rapeseed (PI), 3.8 kg DM lupins + 2.3 kg DM heat treated rapeseed (P2), 3.6 kg DM linseed + 1.4 kg DM rapeseed (P3) or 5.8 kg DM rapeseed (P4). Each diet was formulated to supply sufficient energy and metabolisable protein for maintenance + 43 litres and 0.75kg/d weight loss and to contain similiar levels of DUP (AFRC, 1993).
