Energy balance
A 3-month low-calorie lacto-ovo vegetarian diet and a low-calorie Mediterranean diet produce equivalent reductions in body weight, BMI, and fat mass in overweight omnivores.
If you are overweight and want to lose weight, both a low-calorie vegetarian diet (including eggs and dairy) and a low-calorie Mediterranean diet will work equally well over 3 months. The key is the caloric deficit, not the specific exclusion of animal products, provided you follow a structured plan.
Both Vd and MD were effective in reducing body weight, body mass index, and fat mass, with no significant differences between them.
Why this rating
Randomized crossover trial with good compliance (84.7%) and statistical power, though short duration (3 months).
