The vegetarian advantage for weight loss
Vegetarian diets are naturally high in fiber and often lower in calories at equal volume. Vegetables, legumes, and whole grains offer excellent satiety. Studies show that vegetarians have a lower average BMI than omnivores.
The vegetarian protein challenge
Getting enough protein is crucial to preserve muscle mass during a deficit. Aim for 1.6-2g/kg of body weight. Main vegetarian sources are: eggs, dairy, legumes, tofu, tempeh, seitan, and quinoa. Combine grains and legumes for complete proteins.
Watch out for calorie traps
Vegetarian doesn't automatically mean low calorie. Cheese, nuts, oils, and prepared vegetarian dishes can be very high in calories. Veggie burgers and nuggets are often processed and high in sodium. Prioritize whole foods.
Nutrients to monitor
On a vegetarian caloric deficit, particularly watch iron (legumes, spinach, lentils), zinc (pumpkin seeds, chickpeas), vitamin B12 (eggs, dairy or supplement), and omega-3s (flaxseed, walnuts, rapeseed oil).
Important
Never go below 1200 kcal/day (women) or 1500 kcal/day (men) without medical supervision. Too aggressive a deficit can be dangerous for your health and counterproductive for weight loss.
