Li, Lin et al. Cell Reports Medicine, Volume 0, Issue 0, 101801. Effects of healthy low-carbohydrate diet and time-restricted eating on weight and gut microbiome in adults with overweight or obesity: Feeding RCT
Methods: The participants (n=96 adults) in the combination of Healthy Low Carbohydrate Diet (HLCD) and Time Restricted Eating (TRE group were provided with HLCD and instructed to follow the 10-h TRE. The HLCD … consisted of approximately 30% of total energy from carbohydrates, 50% from fats, and 20% from proteins. Moreover, compared to a traditional low-carbohydrate diet that only focused on carbohydrate restriction, HLCD also emphasized healthy food sources and high-quality macronutrients such as unsaturated fatty acids, plant proteins, and high-quality carbohydrates, including whole grains, fresh vegetables, and fruits. Additionally, 25–35 g of mixed nuts were provided along with HLCD per day, which mainly included walnuts, peanuts, cashews, pistachios, pecans, almonds, and hazelnuts. 10-h TRE required participants to consume the provided meals within 10 h each day. Outside the eating window, only water, and noncaloric beverages were allowed.64
Key findings:
- Each of the patient groups lost between 2.57 to 4.11 kg
- HLCD was more effective in reducing fat mass
- Both dietary interventions resulted in changes in the microbiome
My take: It is still to work on improving diet quality and improving exercise –only a small percentage of patients will be receiving GLP-1 drugs or bariatric surgery. The Mediterranean diet likely has the most data supporting its use for obesity.
