If you have 15 points left you are not eating the correct foods, and abusing zero point foods. Zero point foods are not meant to be your main dish, but to supplement healthy choices so you don't feel hungry. Base each meal around a lean protein, and veggies I Try to make each meal around 8 points, then use the extra points for snacks, and or treats. If I made bad choices through out the day, you can have a low point dinner, and still be ok. By eating all your points, you are doing 2 things getting the proper nutrition for the day, and eating enough calories for healthy weight loss. Not eating enough will stall your loss, and without getting proper nutrition will lead to other physical issues.
