The new video in which Dr. Franco Berrino , researcher and epidemiologist famous for his advice on proper nutrition, is making the rounds of the web.

In this video, in fact, Dr. Berrino explains how to lose weight without doing a slimming diet, but in a perspective that he defines as healthier. As the doctor explains, losing weight in health is possible as long as we change our life on two main aspects.

The first is physical activity, the other is to change your diet. 

We all agree on physical activity, right? I mean that if you hope to change your diet without moving, you will always have to deal with a sedentary lifestyle.
Dangerous for health, a sedentary lifestyle is the main obstacle to a good metabolism. 

Berrino therefore focuses on nutrition: how to change it to lose weight? 
According to him, the main fattening factor is excess protein in the diet .

With high-protein diets you can lose weight, but the diets themselves are not very sustainable in the long term. To limit proteins in general, and animal proteins in particular, remember not to exceed 15% of the daily requirement in the form of proteins.

What about carbohydrates? If pasta doesn’t make you fat, white bread could be an enemy: bread, like white rice and sweets, causes your blood sugar to rise very quickly, then causing spikes in hypoglycemia and new hunger when insulin kicks in.

Berrino cites studies from Harvard University: they make you fat chips, potatoes, preserved meats and cured meats, sugary drinks, meats, foods based on refined flours.
On the contrary, whole foods, cereals, vegetables, fruit, yogurt (a food that is friendly to the intestine), oleaginous fruits, namely walnuts, hazelnuts, almonds. Source: via Scienza.studionews24

Dcomedieta’s opinion.
It is possible that a high-protein diet can cause long-term imbalances, that it is not fattening.
It depends on what we mean by protein foods.
If we mean hamburgers, steaks or processed meats such as cured meats, it is not so much the protein content that weighs on the scale, but that of fat. Plus, these foods never travel alone. 

It is logical that a plate of veal burger with salad for a side dish is not the same as a cheeseburger sandwich with a side of fries and dips. Let’s talk about 4 times the calories of the first example.

So bringing up the Americans by saying that proteins make you fat is very debatable as an argument, and in my opinion tendentious . Today, according to studies, excess sugar and fat together are more likely to do the damage through a diet rich in processed foods. Finally, the insulin hypothesis of obesity, according to which if I eat a “refined” fattening food, has yet to be proved.
