Had an apple for breakfast this morning instead of my regular mini muffin or waffle and honey since I have another reason to avoid sugar. It gives you quick boost but it doesn't last long and so gives you crash in the level of energy. Not only that but sugar itself doesn't trigger the body to produce insulin like carbohydrate does, and therefore more gets converted to fat.

Now I also understand why I should not be eating a big meal at night or eating too late unless I want the beer belly. Your metabolism system shuts down at night. Therefore, what you eat will not be burned as fast at night as during the day. Thus, it gets converted to fat.
