Walnuts help you lose weight: is that true? Easily explained
That walnuts are very healthy is not new. Neither does the fact that walnuts have a lot of calories. Scientists from the Beth Israel Deaconess Medical Center have now investigated whether nuts can help us lose weight despite the numerous calories.
- The good news first: Yes, walnuts can definitely help us lose weight, although scientists are still at the beginning of their research.
- Ten subjects took part in the ten-day walnut study, the results of which the scientists are now publishing in the specialist journal “Diabetes, Obesity, and Metabolism”.
- Participants in the study were split into two groups, with one group receiving walnut smoothies and the control group receiving a placebo that looked and tasted the same. Changed after five days.
- In their investigation, the scientists not only evaluated the information provided by the participants regarding their feeling of satiety. The information provided by the subjects was verified using functional magnetic resonance imaging. With this method, the researchers can observe the activities in the individual regions of the brain.
That’s why walnuts help you lose weight
Using magnetic resonance imaging, the scientists found that eating walnuts had a neurocognitive effect on the regions of the brain that are largely responsible for our eating habits.
- By enjoying the walnuts, the participants felt significantly better and, above all, felt fuller for longer. However, due to the nutrient density of the nuts, this was not a big surprise for the scientists at first. What was surprising, however, was that the walnuts activated the area of the brain that is involved in the selection of our food.
- Since the participants felt full and satisfied, they then proceeded much more consciously with their further food choices. They opted for healthier foods, even if they didn’t seem so tasty at first.
- Basically, however, this is nothing more than what nutritionists have been preaching to us for a long time. Never go shopping on an empty stomach, as you will quickly reach for food that would otherwise never have found its way into the shopping cart.
- Conclusion: As positive as the result is initially, it must not be forgotten that walnuts have a very high-calorie density. The scientists therefore want to first verify the result in further studies and then find out from what quantity of walnuts the effect, which is ultimately beneficial for weight loss, begins. However, the walnuts are not a miracle, but only a tool. If you really want to lose weight, you need discipline.
