Negative Calorie Foods: The New Super Weight Loss Strategy?

You may have heard that you can lose weight by eating negative calorie foods. That is, foods that require more energy to digest than they provide calories. Celery is a commonly cited example because it’s mostly water and fiber.

The internet is full of lists of so-called negative calorie foods, that is, foods that are said to take more energy to digest than they provide calories. Many of these foods are actually vegetables and fruits, which can be part of a healthy diet. But they probably aren’t negative calorie.

The theory is that you can lose weight by eating lots of these negative calorie foods. Proponents of this theory claim that you will burn more calories digesting celery than it contains, for a net loss.

Negative Calorie Foods: Do They Really Work?

Here is the reality. Throughout the day, approximately 5 to 10% of your total energy expenditure goes to digestion and storage nutrients in the foods you eat.

Foods that are low in calories, such as celery and other non-starchy vegetables, do provide a small number of calories. But they still need energy to be digested. This means that it is theoretically possible to have a negative calorie food. At the moment, there are no reputable scientific studies to prove that certain foods have this effect. However, even though non-starchy vegetables are not negative calorie, they are still low in calories and are a smart choice to include in a vegetable-based diet.

Be careful with new fashion claims slimming. Following extreme diets that promote the consumption of only a few foods can deprive you of important nutrients. The key to successful weight loss is adopting a healthy lifestyle that includes a balanced diet and regular exercise.

Boost Your Metabolism to Lose More bad idea

The key to successful weight loss is to adopt a healthy lifestyle that includes a balanced diet and regular exercise. Trying to boost your metabolism probably won’t result in weight loss. At least not to the point of changing your diet and lifestyle. Metabolism is the process by which your body converts what you eat and drink into energy. Even when your body is at rest, you continue to use energy for basic functions such as breathing, blood circulation, and cell repair. The energy your body uses for these basic functions is called basal metabolic rate.

Caffeine for example increases metabolism very slightly. But it doesn’t seem to have a significant effect on long-term weight loss. Supplements claiming to boost your metabolism may have little or no benefit and may contain substances that have serious side effects. How much weight you gain depends largely on the food choices you make and the physical activity you do.

To lose weight, focus on these two factors you can control


To lose weight, you must burn more calories than you absorb it. There are several ways to reduce the number of calories you consume. Including reducing portion sizes, limiting added sugars and saturated and trans fats. At the same time, choose fruits, vegetables, whole grains, lean proteins, and healthy fats over processed foods. And remember that as you age, you may need to consume even fewer calories. This is because the amount of muscle you have tends to decrease with age. Your muscle mass affects the number of calories you need. Because muscle tissue burns calories, even at rest. Thus, having less muscle decreases your calorie needs by lowering your basal metabolic rate, while having more muscle increases your calorie needs by increasing your basal metabolic rate.

The physical activity

Exercise helps you burn calories and build and maintain muscle mass. Any physical activity is better than no activity. Start slow, and work your way up to incorporating both endurance and strength training into your routine. If you’re worried about your weight or think your metabolism is too slow, talk to your doctor. He will be able to check for medical causes and help you adopt a healthy lifestyle to help you lose weight.
