Every person has different eating habits. As we all know that people in different countries take different diets but in the end the body gets what it wants. However, it is very important to eat anything in proper proportion. We gain weight because we leave some of the food items which we do not want to eat and eat those in excess which we like to eat.
I found all this information on ahealthdir.com. You can visit this site and see what is best for you according to your eating habits. And yes dieting does not mean that you are not going to have an ice cream or other sweets. But remember do justice as excess of everything is bad. Hope my suggestion helps you.
