Maximum Keto Have soup and salad for every lunch. An oversized pile of salad greens with a fat free dressing. Add chopped red onions and tomatoes. We're talking as compared to 100 calories for an immense plate. Have a cup or 2 of soup as well. But the good ones. No cheating with chowders and cream-of-put-it-right-on-my-hips. Purchase the clear soups and the broths.
