Is It True That Negative Calorie Foods Help Lose Weight?
Negative calorie foods allow you to burn more calories than you eat, that is you lose weight by eating negative calorie foods. Does it sound too good to be true? The fact is that it is not true. The negative calorie diet is based on misunderstanding of nutrition facts. Your body burns calories when digesting meals, but this process accounts for up to 30% calories you get from so called negative calorie foods. For example, celery is considered to be negative calorie food. Celery is low in calories as a cup of celery (120 g) contains only 19 calories. However, it takes your body only 2 calories to digest it. You should eat celery as it is high in dietary fiber, calcium, vitamin A, B6, C. Low-calorie foods help you feel full so they help you lose weight by reducing your total calorie intake, but they do not help you burn calories.
Some beverages (water, tea or coffee with no milk or sugar) contain no calories. Your body burns calories when digesting these beverages, but the effect is not noticeable. Drinking beverages help you burn 5-10 extra calories a day. If you take into account that you have to burn 500 extra calories a day to lose a pound per week, you see that 10 extra calories do not make any significant difference. Tea and coffee can also raise your metabolism for about 10% for an hour or two, but this still does not allow you to achieve significant weight loss.
There is no scientific evidence that negative calorie foods exist. You have to face the truth. Exercises are an important part of your diet regime. You can burn calories by running or walking, but you cannot burn calories by eating.
