The starting point for weight loss at 40: Understanding body differences and lifelong health goals

2026-05-23

**Start losing weight differently now if you're 40!**

Most people, when trying to lose weight, simply repeat the same routine endlessly, neglecting the most crucial issue.

This is how 20-year-olds lose weight.

The methods for losing weight at age 40 are fundamentally different.

Many women in their forties who are trying to lose weight complain, "I wasn't like this before," claiming that they had no excess fat in their twenties.

Most of them start needing to buy clothes one size larger than before after the age of 35, while gaining about 5-6 kg in weight and increasing their waist circumference by nearly 5-7 cm.

They claimed they had never changed their eating and lifestyle habits, and therefore had no idea why they had gained weight.

Everyone I used to know envied my slim figure, but now I feel sad because of my changed body shape, and I don't even have the interest to buy clothes.

Many people also complain that they used to hear shop assistants compliment their slim figures and feel that they could wear any clothes; however, they don't know when, such compliments have gradually decreased and disappeared from their memories.

In fact, when people reach their 40s, even if they maintain the same weight as they did in their twenties, the increase in fat in areas such as the abdomen, ribs, and forearms can cause their bodies to start to deform. Ultimately, this is due to the presence of "age-related fat."

"Age-related fat," as the name suggests, refers to fat that is gained or cannot be lost due to aging.

However, how can this phenomenon be explained from a medical perspective?

The reasons for the increase of "age-related fat"

When we are in our twenties, we can easily lose 2-3 kg by dieting for a day or two.

As people enter their 30s, even if they only drink a few beers at a company party, they can easily gain about 1kg the next day.

So what is the purpose of this?

Everything happens for a reason.

The reason why we gain weight as we age is our "basal metabolic rate".

In your twenties, the body's basal metabolic rate, the minimum amount of energy required to maintain life, is very high.

Moreover, the twenties are a period of high physical activity, during which the body secretes large amounts of growth hormone.

Growth hormone is a hormone that promotes the growth of various organs in the body and enables the normal functioning of various organs in the human body.

In addition, the secretion of growth hormone also has a significant impact on the increase of basal metabolic rate.

When people reach their thirties or forties, the secretion of growth hormone decreases significantly compared to their twenties, and their basal metabolic rate also decreases, naturally leading to the formation of "age-related fat."

As we age, the secretion of sex hormones gradually decreases.

This is also one of the reasons for the formation of "age-related fat".

A decrease in sex hormones can cause fat accumulation in the abdomen of both men and women, and also lead to a decrease in muscle mass.

A decrease in muscle mass means a decrease in the body's metabolic rate.

In other words, even if we maintain the same level of exercise as we did in our twenties, the decrease in metabolism will reduce the body's ability to burn energy, leading to weight gain.

Blindly using starvation diets can only lead to water loss and muscle loss, but it cannot fundamentally achieve the effect of weight loss.
