Why do some people eat but never gain weight? Here are some tips to help you develop a "thin body"!

If you want to talk about the most enviable physique, it must be the physique that does not gain weight. Eat fried chicken and hot pot, milk tea today and cola tomorrow. Hey, just don't gain weight!

But some people gain weight even by drinking water. It seems that if they drink a few more sips of water today, they will gain two pounds of weight tomorrow.

This means that for these people, even the most basic daily water intake - drinking water, seems to have become a subtle factor in weight gain. This is not a direct scientific cause and effect, but reflects that they may have a physique that is prone to obesity, a slow metabolism, or a combination of factors such as eating habits and lifestyle. Therefore, they often feel troubled, as if they need to be cautious even in their most basic physiological need - drinking water, for fear that the slightest mistake will lead to weight gain.

Why is the gap between people so big?
Genes are indeed important for not gaining weight. Whether you are prone to gaining weight or not, it is all related to a "glutton gene".
In medicine, this gene is called FTO gene, which stands for Fat mass and obesity-associated gene. It is located on chromosome 16 of the human body. This is a common obesity susceptibility gene in the human body. Everyone has it, but some people's FTO gene is mutated.

Those who don't easily gain weight are mostly the lucky ones whose FTO gene has not mutated. They can easily feel full once their body has taken in enough calories to maintain normal physiological activities. Therefore, they can easily get full, and even if the food is delicious, they can easily stop eating when they are full, and they are unlikely to have the problem of excessive calorie intake.

What's more, the main motivation for them to eat is hunger, not "I'm in a bad mood", "I'm in a good mood", "I'm so angry, let's eat something", and other various reasons that cannot be called reasons at all.

People who always find various reasons to arrange a meal for themselves and often cannot stop eating may be people with mutated FTO genes. For people with mutated FTO, they really can't control themselves.

In their brains, food not only provides calories and maintains normal physiological functions, but is also a source of happiness. High-fat and high-sugar foods are huge rewards for their brains. The happiness brought by this reward can even overwhelm the alarm signals of the gastrointestinal tract. Compared with the happiness brought by food, the intensity of the satiety signal is too weak.

Simply put, people with no FTO gene mutation will not eat more than one bite after they are full, while people with FTO mutation may eat two more bites after they are full, even if they are not hungry.

If you have the obesity gene, you can’t lose weight? Of course not!

"Control your diet and move your legs" is definitely the most effective rule for maintaining and losing weight. And behind this golden rule is actually creating a calorie deficit.

The human body needs to consume a certain amount of calories every day to maintain normal physiological activities, which is the basal metabolism.

Even if you sit still all day, the body will consume these calories because they are used to maintain the body's temperature, breathing, heartbeat, blood circulation, and the energy needed for the normal operation of various cells and organs.

Basal metabolism accounts for about 60% to 75% of daily energy consumption, which is the bulk of daily energy consumption.

In addition, the human body consumes extra energy for daily walking and exercise. The consumption and absorption of food itself also requires energy, which is called the thermal effect of food. Therefore, the energy consumed by the human body every day is actually the sum of basal metabolism, energy consumed by daily activities, and the thermal effect of food.

Everyone consumes a certain amount of food every day, which can provide a certain amount of calories to the human body after digestion and absorption. If the calories consumed every day are higher than the calories consumed, this calorie gap will make it easier for the body to lose weight.

And if the energy intake is more than the energy expenditure every day, then obviously, obesity will naturally occur.

At this point, we have to say a cruel fact, some people's basal metabolism is indeed higher than others. Therefore, these people can lose weight even if they don't move! But fortunately, basal metabolism can be changed through acquired efforts. In a static state, muscles consume more calories, so increasing the muscle content of the whole body can naturally increase basal metabolism.

This is also the reason why people who have long-term exercise and fitness habits eat a lot but don’t gain much weight.

Long-term exercise can increase skeletal muscle content, thereby helping to consume more calories. Even if they sit or lie down for a whole day, they can consume more calories than ordinary people.

In fact, long-term dieting will affect the body's basal metabolism. In order to maintain normal physiological activities under low calorie intake, the body will reduce consumption and even consume muscle, which will form a relatively low basal metabolic level over time.

Therefore, if you want to lose weight and keep it off, don't diet too much. A healthy diet plus regular exercise is the most effective and healthiest way.
