If you eat more calories than you need, you gain weight. This principle is questioned by researchers. You blame something else for body weight.
- If you want to lose weight, you always hear the same thing: You should do a lot of sport and eat less.
- But many who try to slim down in this way fail. On the other hand, there are people who eat all day but do not gain weight.
- American researchers have now addressed this phenomenon - with astonishing results.
This part of the body needs a lot of energy - and we don't notice it
So our brain should be a real "energy eater" . The brain consumes around a quarter of the energy we consume throughout the day. And not just when we strain our gray cells at work or learn languages: Our brain burns the most energy in the form of glucose when it forms hormones and controls metabolism and organ functions, as the Focus reports.
"To say that obesity is an energy balance problem is like to say that fever is caused by temperature imbalance," said Dariush Mozaffarian, Dean of Friedman School. The assumption that obesity is triggered by a chronic "too many calories" is accordingly in his eyes too short . Or the other way around: if you eat fewer calories than you consume every day, you don't necessarily have to lose weight.

Fat despite diet - that could be behind it
It's not just the brain that affects our body weight. Other factors also control whether we are slim or sturdy . These include:
- the type of food : some foods such as white flour products or sugar promote weight gain. On the other hand, vegetables, nuts or fruit hold or make you slim. The secret is in the fiber: These not only fill you up longer, they also burn additional calories and thus promote weight loss, as a study showed.
- genetic predisposition : much that is crucial for body weight is inheritable. For example our metabolism, the number of fat cells in the body or our feeling of satiety . "Reprogramming" these processes is only possible on a small scale - or not at all.
