Low calorie, low carb meal substitutes are one of the best ways to lose weight. If you’re not hungry, don’t eat. Skipping meals is one of the best ways to lose weight. But when you are hungry, and you feel like you have to eat – a low calorie, low carb meal substitute usually packs in fewer calories than a traditional meal. Costco and Sam’s Club are loaded with protein bars. Look for a bar with at least 15 grams of protein, and no more than about 150 calories. That’s your meal substitute. Low calorie (look for about 100 calories) Greek yogurt is another good meal substitute. As are hard boiled (70-80 calorie) eggs. As is cottage cheese at 200 calories per cup. Staying away from traditional meals is one of your most powerful weapons for losing weight
