Says diet band wagon. They don’t call them special diets for no reason. Without the food pyramid you will develop deficiencies. Which could easy lead to ailments. I don’t think the portions are realistic, some to forever strive for, not. Any new diet that comes out is looking for something that already exists. It could benefit some people. I would say more than most will excel with the food pyramid, family safe to. We all are unique and some may require a specialized diet. But remember that’s what it is and it will have negative consequences. Rather curtail your specific food to their grouping and agreeability.
