Not everyone overeats and becomes overweight, and not everyone who becomes overweight or obese develops illnesses like diabetes or heart disease.
There was never a special diet, exercise regimen, or supplement that worked universally to control weight. Through trial and error, we have to discover habits and routines we can stick with that help us eat less and move more.

A person with slow metabolism will not burn the same quantity of energy as one with a fast metabolism.
What still remains a moving target is how the speed of metabolism varies from one person to another, and what will turn it up or down.
The energy value of any food is measured in calories, and the basal metabolic rate is the minimum amount of calorie count that is required when the body is at rest (Resting Energy Expenditure). Combining it with the energy one consumes while moving around or digesting food gives us the total energy expenditure.
Our body energy needs are dependent on our age, height, weight, genetics and gender, apart from our daily activity.

There are 3 main ways:
Most of the energy you burn is from your resting metabolism.
Metabolism can vary a lot between people, and researchers don't understand why.
2 people with the same size and body composition can have different metabolic rates. One can consume a huge meal and gain no weight, while the other has to carefully count calories to not gain weight.
The calories we burn every day include not only movement but all the energy needed to run the thousands of functions that keep us alive.
Exercise is like a wonder drug for many health outcomes: reducing blood pressure, reduces the risk of diabetes of heart diseases and slows developing cognitive impairment from Alzheimer's and dementia.
But as for losing weight, it helps more in weight maintenance than in losing the actual weight.
Exercise alone has a modest contribution to weight loss. But when you alter one component, cutting the number of calories you eat in a day to lose weight, doing more exercise than usual, this sets off a cascade of changes in the body that affect how many calories you use up and, in turn, your bodyweight.
