Article Synopsis

  • The trial aimed to compare the effectiveness and acceptability of a combined approach of early time-restricted eating and daily caloric restriction versus caloric restriction alone for weight loss.
  • Participants (81 total, mostly women, average age of 38) were divided into two groups and monitored over 39 weeks, with various health metrics assessed at week 12 and week 39.
  • Results showed no significant differences in weight loss or other health outcomes between the two groups, suggesting that combining early eating windows with caloric restriction is just as effective as caloric restriction alone.

Article Abstract

Objective: This trial aimed to evaluate the acceptability and efficacy of early time-restricted eating plus daily caloric restriction (E-TRE+DCR) compared with DCR alone within a behavioral weight-loss intervention.

Methods: Participants (n = 81, 69 women, mean [SD] age: 38.0 [7.8] years, BMI: 34.1 [5.7] kg/m ) were randomized to E-TRE (10-hour eating window starting within 3 hours of waking) plus DCR or DCR alone (~35% DCR) for 39 weeks. The primary outcome was body weight (measured with digital scale) at week 12. Secondary outcomes measured at week 12 included hemoglobin A1c, lipids, energy intake (photographic food records), physical activity (accelerometry), dietary adherence (questionnaires), and body composition (dual-energy x-ray absorptiometry). Weight and body composition were also assessed at week 39.

Results: Mean [SD] weight loss was not different between groups at week 12 (E-TRE+DCR: -6.2 [4.1] kg vs. DCR: -5.1 [3.2] kg) or at week 39 (E-TRE: -4.9 [5.3] kg vs. DCR: -4.3 [5.3] kg). There were no between-group differences in changes in body composition, dietary adherence, energy intake, physical activity, hemoglobin A1c, or lipids at week 12.

Conclusions: E-TRE+DCR was found to be an acceptable dietary strategy, resulting in similar levels of adherence and weight loss compared with DCR alone.

Bifidobacteria are naturally found in the human gut and quickly establish dominance shortly after birth, playing a crucial role in the development and stability of the infant gut microbiota. A growing body of research suggests that host and environmental factors shape the colonization and the relative abundance of bifidobacteria in the infant gut during early life. Understanding the factors that influence bifidobacterial colonization and maintaining normal colonization levels are keys to ensuring gut health.

The purpose of this study was to investigate the efficacy and safety of add-on metformin treatment in persons with active epilepsy (a-PWE). This is a single-centric, double-blind, placebo-controlled trial randomised a-PWE (1:1) to receive either metformin (extended-release 500 mg) or matching placebo for 6 months along with background antiseizure medications. Primary outcome was percentage change in seizure frequency/month, and secondary outcomes were 50% responder rate, serum mTOR expression, and serum total antioxidant capacity (TAC), body composition analysis, quality of life (QOL), and safety assessment.

Purpose Of Review: Despite major advances in the treatment and prevention of atherosclerotic cardiovascular disease (ASCVD), a substantial burden of residual risk remains Obesity has been redefined as a primary and independent drivers of cardiovascular morbidity and mortality warranting focused attention.

Recent Findings: Obesity is now recognized as a chronic disease and a central contributor to residual cardiovascular risk through mechanisms including systemic inflammation, insulin resistance, dyslipidemia, and endothelial dysfunction. This review addresses the limitations of conventional obesity management and highlights emerging pharmacological therapies targeting the underlying adiposopathy.

Background: The objective of this study was to compare the effects of daily consumption of white potatoes compared with white rice on cardiometabolic health in individuals with type-2 diabetes (T2D).

Objective: To determine the effects of white potato consumption compared to white rice (a commonly consumed refined grain) on indices of glycemic control and cardiovascular health in individuals with overweight or obesity and T2D.

Methods: In this randomized crossover study, comparative control trial, 24 adults with T2D [45-80 y, body mass index (kg/m) 25-40] consumed baked white potatoes (100 g) or calorie-matched white rice (75 g) daily for 12 wk, separated by a 2-wk washout, with assessments of glycemic control, lipids, inflammation, blood pressure, endothelial function, and body composition at baseline (only 1 baseline visit included as a covariate in statistical analyses), 6 wk, and 12 wk.

Nutritional status, immunonutrition, and gut microbiome: a coming of age for immunotherapy?

In the last decades, immunotherapy has revolutionized cancer treatment. Despite its success, a significant number of patients fail to respond, and the underlying causes of ineffectiveness remain poorly understood. Factors such as nutritional status and body composition are emerging as key predictors of immunotherapy outcomes.
