Adopting a plant-based vegan diet for 16 weeks significantly reduces body weight, fat mass, and insulin resistance (HOMA-IR) in overweight individuals compared to maintaining a standard omnivorous diet.
Switch to a whole-food, plant-based diet (vegetables, grains, legumes, fruits) with minimal added oils for 16 weeks. You do not need to count calories strictly, but focus on replacing animal proteins with plant sources. This approach has been shown to significantly reduce body weight and improve insulin resistance in overweight adults.
The plant-based vegan diet proved to be superior to the control diet in improving body weight, fat mass, and insulin resistance markers. Only the vegan group showed significant reductions in body weight (treatment effect −6.5 [95% CI −8.9 to −4.1] kg; Gxt, p < 0.001), fat mass (treatment effect −4.3 [95% CI −5.4 to −3.2] kg; Gxt, p < 0.001), and HOMA-IR (treatment effect −1.0 [95% CI −1.2 to −0.8]; Gxt, p = 0.004).
Why this rating
Randomized clinical trial with a control group, though open-label and relatively short duration (16 weeks).

- Total daily protein intake of 1.6 g/kg/day is sufficient for maximizing resistance training-induced muscle gains, with an upper confidence interval of 2.2 g/kg/day.Strong
- Resistance exercise training combined with sufficient dietary protein intake acts synergistically to maximize skeletal muscle hypertrophy, with protein intake saturating around 1.6 g/kg/day for general populations and potentially requiring 2.0-2.2 g/kg/day for resistance-trained individuals.Strong
- Trans fats should be completely eliminated from the diet, as they increase LDL cholesterol, decrease HDL cholesterol, and are directly associated with increased coronary risk.Strong
