I recently just had a slimming program in which I was just allowed to eat 500 calories a day. When I first heard of the small quantity of food that I had to take, I thought at once that aside from it will make me slimmer, it will be a very good way of saving up, too! I thought that since it will be just in small proportions, I would buy lesser foods. Turned out that it did not. The food listed in my "allowed to eat foods" were the ones that cost more than the average in the supermarket. Like, chicken breast is part of the list and that is more expensive than the other parts of the chicken. Also, I was only allowed to eat white fish, and again, has higher cost compared to other fishes. The bread must be from a specialty health store, and another expensive commodity. The slimming program is no doubt effective. BUt looking back, I had too much to spend. Now I am doing my best to keep in shape so as not to go back to that kind of program again.
