JAKARTA - Having a thin body does not mean being free from fat problems in the stomach. A bloated stomach can appear even though the body weight looks ideal.

This happens because body composition is not only determined by body weight, but also fat distribution and muscle mass. This condition is often referred to as skinny fat, which is when the body looks slim, but stores fat in certain areas, especially the stomach.

To understand the occurrence of skinny fat, you need to look deeper than just body weight, from daily habits to internal body conditions. The following are some of the causes of a bloated stomach despite being thin.

1. Less active lifestyle

Quoted from the Mayo Clinic, on Thursday, April 16, 2026, an inactive lifestyle is one of the main causes of a bloated stomach in a thin body. Like sitting too long, rarely moving, and just spending time with gadgets.

This habit makes daily calorie burning decrease drastically. This makes the body easier to store fat, especially in the abdominal area which makes it accumulate to form a distended stomach.

2. Genetic factors and body conditions

Flabby bellies in thin people can happen for things that aren't completely controllable. Like genetics, which can determine where a person's body tends to store fat.

Some people easily store fat in the thighs, cheeks, and others in the abdominal area. In addition, body conditions such as hormonal changes, certain medical conditions, and even drug side effects can also affect body composition.

Therefore, understanding this factor is important in dealing with a distended stomach, so that you can focus on things that can still be controlled. Such as diet to physical activity.

3. Unbalanced eating patterns

Another cause of a distended stomach in an ideal body is an unbalanced diet. This is because the quality of nutrition determines the shape of a person's body.

Many thin people actually consume high-calorie foods, but low in nutrients such as processed foods or junk food. This makes the body lack essential substances to build muscle, but still store fat.
