If you want to lose weight without alienating your friends, the low-carb diet is certainly not the right thing for you. In one study, 106 participants followed a strict diet over a period of 12 months. There were two groups: Low-carb diet and low-fat diet.

The participants were weighed regularly and their mental function was tested. Both groups had the same success in terms of weight loss, but the low-carbohydrate dieters showed signs of general irritability and irritability, while the low-fat dieters were much more balanced.

There are several possible explanations for this phenomenon. Firstly, in a society whose diet is full of bread and pasta, it is relatively difficult to follow a low-carbohydrate diet on social occasions. Furthermore, protein and fat intake have an effect on serotonin levels in the brain. Serotonin is a neurotransmitter that is linked to psychological state.

On average, each participant lost 13.7kg in 12 months. 2 months after starting the diet, both groups reported a general improvement in their mood, but only the participants on the low-fat diet maintained this after the 2 months.

A high carbohydrate, low fat diet with controlled calorie intake is most recommended for people who want to lose weight.
