Sugar, in any shape, form, or fashion.

Read labels carefully, however, because manufacturers have begun to call sugar by many different names - sucrose, dextrose, and so on. Basically, if it ends in "-ose" assume it's a sugar unless you're certain otherwise. (By the way, fructose is metabolized almost the same way the regular sugar is, and as such is not a good substitute).

Anything fried in additional oil.

If you can fry it without adding butter, shortening, or oil, that's fine. This means you don't have to broil your hamburger - just drain it well.

Fruit juice

For the same - or fewer - calories, you can have a piece of fruit that also has a more filling effect and higher fiber.

Non-diet carbonated beverages.

High in calories and sodium with zero nutritional value.

Peanut butter.

The calories are extremely high per serving, and consist almost entirely of sugar and fat.

If you must eat any of these foods try using Thermadrol to help with burning up the calories
