In the 19th century, he was looking for a way to compare the weight of people to their height so that he could see if people were in the healthy weight range. However, this was not all that he did. He actually created this formula to stop people from using their body as a way to measure health.

Should I lose body fat before building muscle?

The answer is yes. The reason is: if you don't lose fat before you start building muscle, you will be adding fat to the areas where you are adding muscle. However, once you have lost the fat, you will be able to add muscle to the areas where you want it more efficiently. It's a matter of fat distribution.

While you might gain an inch or two around your arms through muscle building, you might gain 4 inches around your waistline if you don't decrease your fat levels first. So the answer is yes, you should lose fat before you start building muscle.

Losing fat may sound simple enough, but it can be a difficult task for people who are overweight. The key to losing fat is to create a calorie deficit by eating less and exercising more. It can be difficult for one who is overweight to start a weight loss program. They may be worried about exercise hurting their joints or that they won't be able to keep up with the exercise once they become more fit.

However, women who are overweight can begin by adding small amounts of exercise into their daily routine. They can choose activities they enjoy, such as walking around a mall or a local park. They can also start by adding a few minutes of exercise each day.

What body fat percentage to see abs?

Anyone who has had a weight loss goal knows that the biggest obstacle standing in the way is simply your body fat percentage. For many people, the number on the scale just doesn't go down until they get lean enough to see their abs.

At this point, the weight loss becomes much easier. You'll have a ton of energy, and your clothes will fit better. But what if you want to know your body fat percentage before you get to that point? Understanding body fat percentage is an important part of healthy living.

To see your abs, or body fat percentage, you need to have a low body fat percentage - a body fat percentage of 10 - 12% for men and 14 - 17% for women. You should also have lean muscle to show the abs, not just fat. This is why it's important to train your body for lean muscle, rather than just fat loss.


Body Mass Index (BMI) is a measurement that assesses the relationship between a person's weight and height. It is commonly used to categorize individuals into different weight status categories, such as underweight, normal weight, overweight, and obesity.

BMI is calculated by dividing a person's weight in kilograms by the square of their height in meters. The formula is BMI = weight(kg) / (height(m))^2.

  • Underweight: BMI less than 18.5
  • Normal weight: BMI 18.5 - 24.9
  • Overweight: BMI 25 - 29.9
  • Obesity: BMI 30 or greater

BMI provides a useful general assessment of weight status for most individuals. However, it does not differentiate between weight from fat and weight from muscle. Therefore, for some athletes or individuals with high muscle mass, BMI may not accurately reflect their health status.

No, BMI should be used as a starting point for assessing weight status. It is important to consider other factors like waist circumference, muscle mass, and overall lifestyle habits for a comprehensive view of health.

For the BMI calculation, weight should be in kilograms (kg) and height should be in meters (m). If your weight is in pounds (lbs) or your height is in inches (in), you can use conversion factors to get the appropriate units.
