diets by food

A safe food is presumably safe because it is well-digested and does not contribute an undue body burden of antigenic macromolecules.
Substitute Foods Instead of Eliminating Them: Although many people feel that 'diet' or 'reduced fat' foods are not as good as the original, it can be a big help to buy less fatty snack foods. Try out different reduced fat brands and items and who knows, you may find something that you like even better than the original.

Cutting soda out of your diet completely can save the average person 360 calories or more each day. Even diet soda, fruit juices, and whole milk can add unnecessary calories to your daily intake. Instead, drink lots of water and switch from whole to skim or even soya milk; the little things can make a big difference.

Getting up, moving around, and exercising will reduce the amount of food that you will need to cut back on. There are obviously many opportunities to be athletic and active (i.e. sports teams, the gym, going for a jog, etc.) keep in mind that these aren't the only ways to increase your activity level. You can walk to school, bike to work, walk up and down the stairs a few times before you take a shower, take an extra lap or two around the grocery store. The ideal goal should be 30 minutes of aerobic exercise 3-5 times a week. Gradually ease into your diet if possible. Many diet programs allow you to do this. Remember that small changes are easier to stick with than drastic ones. Start by always leaving a little extra on your plate, or drinking water instead of soda. Smaller changes are also more likely to remain with you when the duration of your diet is complete.
