An interesting but truly bizarre study was conducted by scientists from the University of Gothenburg in Sweden. Basically, according to the authors of the project, it is possible to lose body fat without a diet and without changing diet or playing sports. But with a trick.

This trick caused obese or heavily overweight people who participated in the study to lose over a pound and a half in 3 weeks.
And it’s about clothes.

You can lose body fat without dieting, but by dressing like this

The study participants were divided into 2 groups. men and women with first degree obesity. The former wore normal clothes. Participants in the second group wore a weighted vest for eight hours a day, for 3 weeks. The weight vest had to weigh 11% of their body weight. So let’s say a person weighs 100 kilos. The vest to put on had to weigh 11 kilos.

On the market these vests already exist, with the name of weighted vest or weighted vest, and are used in fitness, in those who train bodyweight.
They have pockets to put the weights into.

Other things required of the participants: to try to spend more time on their feet and to avoid drinking too much alcohol. This is for both the first group and the second group. The result is that the first group, the one who wore normal clothes, stood longer and avoided drinking too much, lost 300 grams in 3 weeks. The second group lost 1.3 kg over 3 weeks. So 1.6 kg.
And substantially of body fat, since the lean mass has remained almost unchanged.

The only limitation found is that the researchers could not say whether the body fat lost was visceral or subcutaneous deep (or how much one and how much the other). However, the effect of the weight vest confirmed the results of a study in mice where the same mechanism was seen.
Let’s see why.

The homeostatic theory of load-dependent body weight

The results should be interpreted according to a theory, that of the homeostasis of body weight (therefore the maintenance of a certain body weight) as dependent on the load, called the “gravitostat” hypothesis.

To be clear: when we spend more time sitting we get fat because we burn fewer calories than standing.
This is because the load on our body is relieved from the sitting position. That is, the chair lifts us a part of the weight of our body which, if standing, would fall on us. The greater the weight that the body has to carry on its own, the greater the energy expenditure.
This thing had been confirmed by a study I have talked about here.
People who sit for a large part of the day experience an increase in visceral fat and a reduction in lean leg and arm mass in the long run. They don’t gain weight, but their body composition changes: they accumulate more fat and lose muscle mass.
