A person who gains weight has a higher calorie requirement. There are two reasons for this. Having to carry a greater mass around and service a more massive body uses more calories. And having a bigger surface area means greater heat loss, since heat lost is proportional to surface area. - A greater calorie requirement results in greater appetite/hunger, so, really, overweight people need to eat more than people of normal weight. If the overweight eat insufficient calories (ie if they 'diet') they may lose weight, but it is at the cost of being hungry. There has never been the slightest evidence that the practice of fewer calories in and more calories out by way of exercise reduces obesity! - It is often confidently stated that fat will be lost by doing this. - Sadly, what is more often lost is lean tissue, usually an irreversible adverse effect.
The result of the misunderstanding of the cause of obesity is the well-known fact that over 95% of dieters actually gain weight in the long term! - They cannot be expected to go hungry all the time. - Nor would staying hungry all the time benefit them. - With insufficient calories for the body's needs, the body feeds on itself. - The skin becomes thinner; the bones become less dense; there is some hair loss, etc.
Contrast this with the safe, effective, fast way to lose excess weight - by eating less sodium. - Eating less sodium releases some of the excess water held in the blood stream. This lowers the blood pressure and, significantly, lowers the weight. - Weighing less results in a lower calorie requirement so very gradually less food is eaten and this becomes a virtuous circle because less food eaten results in lower sodium intake.
In societies in which no salt is eaten (what some might describe as undeveloped or uncivilised societies) there is no obesity and no hypertension.
The cavemen and women who were our ancestors lived for millennia without added salt. Our bodies evolved on a low sodium and high potassium intake. The modern diet has reversed this to high sodium and low potassium. The intake of salt has massively increased in recent years - as has the incidence of obesity.
I submit that the universal 'slimming' advice - to eat fewer calories/less fat and take more exercise - is a major cause of obesity. - All that is usually necessary to lose weight is to eat less salt/sodium. This is a drug-free, cost-free course of action. There are no hunger pangs and no adverse side-effects. It requires no visits to the doctor or to the gym and it WILL work.
