Hello! Congratulations for your two wonderful babies. I think if you gave live to 2 miracles you also can lose fat. The key is to consume less calories than you burn. Try to eat a high protein diet with cheese, egg, cottage cheese, milk chicken, fish and less carbohydrates such as bread, rice, cookies, spaghetti, desserts. A protein diet will help you lose fat and conserve muscle mass which is important for burning calories. For example: breakfast: yogurt fat low percentage, 1/2 fruit of whatever kind, cinammon and seeds.
