Five foods to avoid while on a diet include snacks that contain just carbohydrates, frozen meals, high-fiber snack bars, foods labeled "low-fat" and artificially sweetened beverages.
The body converts carbohydrates into simple sugars. These sugars then go directly into the blood stream and cause the body to produce extra insulin, which in turn causes low blood sugar and hunger. Foods that contain a mix of carbs, fats and protein are a better option as they take longer to digest and allow people to feel fuller for a longer period of time. Consumption of foods made purely of carbohydrates also can also cause sugar cravings.
Low-fat foods are often high in sugar because removing the fat from food takes out some of its flavor. Manufacturers compensate for the flavor loss by adding sugar.
One reason to avoid frozen meals when dieting is that manufacturers of these meals design their products with the longest possible shelf life in mind. To ensure that the meals stay good in the freezer for an extended period of time, they tend to load the meals with sodium, a natural preservative. Sodium causes water retention, which can bloat the body. Further, frozen meals tend to be less satisfying than freshly prepared meals as the portions are often small.
The sweeteners used in artificially sweetened drinks are known to cause food cravings.
