Make a whole meal twice a week, then eat extras the rest of the week. They are very large portions, so you have plenty of leftovers. Then, you are at a disadvantage. Try to buy some whole grain bread, at least. Of course, the better the restaurant you eat in, the better the food is.
Good restaurants have fresh foods, organic chicken, and all kinds of wonderful foods.
You have to eat whole grains, beans and fresh vegetables twice a day. You really have to do it right, and to do that you have to combine nutrients, ensure there's enough fat and protein in the diet, and ensure that the nutrients aren't refined. That's what I teach. You can't keep away from the sweets. If you can't do this, it means there's a protein deficiency.
