BMI 15.5 (What Should Do)

Really, it all depends. Although 15.5 is a low BMI, there are people who have gone even lower, and there are those who live with it. It is ideal for a person with a BMI of 15.5 to review their overall health and determine if their BMI and weight are harming their health. In general, I believe that the BMI scale’s risky zone is 15 and beneath. However, while BMI can only tell you so much, it actually relies on the person who has it. Dropping down to a 15 for someone of average size or larger would be dangerous, however, someone who has always had a naturally low BMI would be fine.

Most people do not aim for a BMI below 18, thus I would steer clear of a BMI of 15.5 in general.

What Does Underweight Really Mean?

A body mass index (BMI) of less than 18.5 is considered underweight. This is thought to be lower than the body mass required for optimal health. Over 25 is considered obese, and over 30 is considered overweight.

However, keep in mind that the BMI scale, which solely considers weight and height, has a number of flaws. It does not take into account muscular mass. Some people are naturally thin, but they are healthy. Being underweight on this scale does not always indicate that you have a health problem.

In comparison to men, girls and women are 2–3 times more likely to be underweight. In the United States, 1% of males and 2.4 percent of women aged 20 and up are underweight.

  • Infections: Certain infections might make a person dangerously underweight. Parasites, TB, and HIV/AIDS are examples.

If you’re underweight, you should consult a physician to rule out any major medical issues. This is especially crucial if you’ve lately begun to lose a lot of weight without even trying.

Protein is the single most important ingredient for gaining a healthy weight. Protein is the building block of muscle, and without it, the majority of those extra calories may end up as body fat. According to studies, a high-protein diet allows many of the additional calories to be converted into muscle during periods of overeating. Keep in mind, though, that protein is a two-edged sword. It’s also quite filling, which may dramatically lessen your hunger and appetite, making it more difficult to consume enough calories.

Aim for 0.7–1 gram of protein per pound of body weight (1.5–2.2 gram of protein per kilogram) if you’re aiming to gain weight. If your calorie intake is extremely high, you can even go higher. Meats, fish, eggs, many dairy products, legumes, nuts, and other high-protein foods are examples. If you don’t obtain enough protein in your diet, protein supplements like whey protein can help.
