Why does a person eat what he likes and consume a lot of food without gaining weight?

It looks skinny.

On the other hand, another person places a lot of controls on his food and if he breaks them and eats a small piece of biscuit, he gains weight quickly.

It is unfair, and it shocks many who seek to research its causes, especially since the claim that "thin people who eat and have a healthy weight have a faster metabolism than others" has been proven wrong.

So, why do some people eat whatever food they like and not gain weight?

And why do others eat healthy food and gain weight?

genetics

Many studies and scientific research pointed to the responsibility of genes in weight gain, as genetic factors play a key role in weight.

According to the Mayo Clinic, genes play a role in determining weight, but it's not as if it's fateful or taken for granted and can't be changed.

Genetics can make a difference in specific factors such as how full you feel when you eat, levels of fullness and appetite, and how your body uses energy and burns calories.

However, environment, lifestyle and healthy choices are still the primary factors that largely control how much you weigh, and genetics is a marginal issue that should not be relied upon.

You are not what you eat

The traditional theory says that the amount of calories people eat and drink has a direct impact on their weight: you consume the same number of calories the body burns over time and the weight remains stable, you consume more than the body burns and weight goes up, you consume less than the weight goes down.

Weight loss programs are based mainly on the principle that some foods and not others contribute significantly to weight gain, including processed foods that contain a high percentage of calories with low nutritional value, and must be avoided to lose weight, according to “My Food” data" (Myfooddata).

High-calorie foods to avoid include: fast foods, processed meats, sweets, fatty meats, white bread products, snacks, sugary drinks, alcohol and spices.

Although this theory seems completely logical, some people eat high-calorie foods and do not gain weight, why?

American food blogger Rebecca Rabin, who runs the "I actually ate that" account, dedicated to displaying pictures of the foods you eat, indicates that not restricting herself to specific foods is the secret to maintaining her slim figure.

"I grew up eating what makes you happy, so many tacos, nachos, late-night pizza, bread and pasta," Rebecca says in an interview with the New York Post.

But even though she regularly indulges in high-calorie foods, Rebecca has a lean body.

"I treat food as something you enjoy, I don't eat in seconds, if I eat delicious pasta I will take my time and eat it. It's all about portion control," she explains.

Perhaps “food portions” is the password revealed by Rebecca, and it was endorsed by Elisa Romy, a spokeswoman for the American Academy of Nutrition, who says in an article on the “Self” website that she finds that “when people stop making prohibited foods, they improve their relationship with food, and from Then they are better able to eat a balanced diet, indulge when they want to, while still maintaining moderation."

Elisa explains that when you feel like you can eat something at any time you end up not eating it at all, or feeling satisfied eating less than you would have when you felt you shouldn't have it at all.

Controlling portions is all there is to it, especially with the worst foods, and it is also important to make sure that you get a healthy mix of food. Green salad can be eaten before a piece of pizza, for example.

Other factors

A common response to the question "Why do some people eat as much as they like and eat a lot but don't seem to gain weight?"

They have a faster metabolism (burning calories) than anyone else, but the answer is wrong.

Professor John Brewer, a dietician from St Mary's University of London, believes that a rapid metabolism is not always the reason for a healthy weight.

John explains through the SBS website that many thin people maintain a healthy weight because of their total calorie intake, not their metabolism.

He added that "a huge number of people who are overweight have a completely normal or very high metabolic rate, but they lose it all because of eating a lot of calories."

More simply, if the body needs two thousand calories per day, and the person eats that amount of calories and then adds simple pieces of biscuit, and continues on that matter, he will gain weight, while if the person eats a meal of unhealthy food on a day and does not exceed two thousand calories Calorie intake, and eat healthy food in the following days, as this will not gain him weight, but it is also possible to lose weight.

In addition to the amount of calories, John lists a number of factors that explain how you can eat and not gain weight, including:

  • Sleep 6 to 8 hours:

    People who sleep less than 6 hours a night regularly may be overweight or obese.

  • Home food:

    Some people eat a large amount of food, but it is mostly cooked at home, and the reliance on processed foods is minimal, and they rarely eat fast food or from outside the house.

  • Sitting while eating:

    People who eat standing food are more likely to eat twice as much of it.

  • Snacks:

    It is best to eat snacks around the time of the main meals and avoid eating them at night or in front of the TV.

  • Building a routine of eating and movement:

    Eating for these people usually turns into a routine, whether cooking or eating it at regular times, as well as movement and choosing simple daily preferences such as taking the stairs instead of the elevator or walking daily.

    Building that regular routine is very effective in losing weight, even if you decide to eat a certain amount of tempting, high-calorie foods.
