To understand why body fat percentage is important, we first need to understand what it is. Our bodies are composed of many different components — muscles, bones, body water, organs, and of course, fat. Fat percentage is the ratio of fat in relation to those other components.
Now, although fat gets a bad reputation, it is essential for many of our body functions. It helps maintain life and reproductive functions, and the accumulation of adipose tissue from stored fat helps cushion and protect the organs in your chest and abdomen. So having accumulated fat is important, but like everything in life, you need to maintain a balance. That’s why calculating body fat percentage is so important in identifying your health — having a body fat percentage that is too high or too low can indicate certain health risks.
There are several methods to calculate this. Here are some of the most common ones.
It’s based on the idea that about 50% of total body fat lies under that skin, and involves measuring the thickness of skinfolds at standardized sizes. It is also known as the Skinfold Method
Steps to calculate body fat using calipers:
This is a value derived from the weight and height of a person; a simple numeric measure of a person’s thinness and thickness. Having a numeric value allows health professionals to discuss weight problems more objectively with their patients. We use this system at our cult centers!
Steps to calculate the body fat using BMI:
Body fat % = –44.988 + (0.503 * age) + (10.689 * gender) + (3.172 * BMI) – (0.026 * BMI2) + (0.181 * BMI * gender) – (0.02 * BMI * age) – (0.005 * BMI2 * gender) + (0.00021 * BMI2 * age)
Uses X-rays to scan and measure whole-body bone mass and soft tissue composition, and is the preferred method for identifying bone and body composition
Steps to calculate the body fat using DEXA:
Uses an imperceptible electrical current to measure body composition. Body fat (adipose tissue) causes greater resistance and slows the rate at which the current travels through the body
an underwater weighing method based on on the Archimedes Principle. A person weighs themselves on land and underwater. The difference between the two values can help determine body density and fat percentage. Tough this is considered one of the most accurate measurement methods, it requires a lot of resources and space and is therefore not the most feasible
Calculates body fat by using a person’s height as a constant and girth of neck and abdominal for male and neck, hip and waist for females
Using any of the above methods can give you an idea of your body fat percentage, but the number alone doesn’t tell you much unless you know how to interpret it. Here’s what body fat percentage means according to the American Council on Exercise (ACE)
As you can see, the values differ for men and women, and there are further differences if you break these groups down by age. You may have noticed the term ‘essential fat’. This refers to the fat present in bone marrow, nerve tissues, and organs, and can’t be lost without compromising physiological functions. The chart above shows that women need to have higher essential fat percentages, as these fats are very important in maintaining hormonal balance and aiding and protecting the reproductive organs.
These numbers are useful in determining whether a person is underweight, at a normal weight, overweight, or obese, which can have a direct link to their health. Higher body fat percentage, for example, is linked to a myriad of health issues, including cardiovascular disease, hypertension, insulin insensitivity, diabetes mellitus, and even certain types of cancer. If your body fat percentage is too low on the other hand, you’re at risk for anemia, malnutrition, osteoporosis, low immunity, and, if you’re a woman, fertility issues. Knowing your body fat percentage can also give you an idea of how fit you are and what you need to do to work towards your fitness goals.
You can reduce your body fat percentage by reducing your overall weight. There are many ways to do this in a healthy way — without going on a hunger strike! Try the following tactics:
Consume fewer calories than you burn. Everything you eat is converted into fuel for your daily activities. When you consume more calories than you can burn, it’s stored as excess fat. You can prevent this with a caloric deficit of about 10-20%. Of course, this doesn’t mean you cut out all high-calorie foods from your diet. Remember that your body needs calories for day-to-day functions like muscle repair and sustained energy. You want to make sure you have the right kind of nutrients — proteins, carbs, and even fats — in your diet to stay functioning throughout the day!
Focus on cardiovascular and resistance training. A low-calorie diet alone isn’t enough to reduce weight, it needs to be complemented by the right workout. Cardiovascular and resistance exercises are great for this because they help build and maintain lean muscle mass — which in turn reduces body fat. Weight training is particularly important in your fat loss journey because, when done properly, it creates a greater caloric expenditure than steady-state cardio. And don’t forget consistency is key in maintaining both muscle gain and weight loss.
Weight loss doesn’t necessarily mean loss of fat. Losing weight signifies a loss in total body mass, but this doesn’t mean you’re reducing your stored fat. Loss of lean muscle mass or less water retention can also result in weight loss. Keep in mind that you can only lose body fat by following a caloric deficit and a good training program. In fact, research shows that fat loss without sacrificing muscle is more effective when caloric deficit is achieved through training. Keep track of the calories you consume and the activities you do and find the right balance between the two. If you find your caloric intake is high and your activity level is low, look into increasing the level and frequency of the workouts. If you feel like you’re doing the right amount of exercise but are still taking in too many calories, it may be time to make some dietary changes. Choose wisely to make sure you’re not losing valuable muscle mass instead!
Body fat alone is not an indicator of health, although it is a main component. A person’s lifestyle, metabolism, and workout regime are other indicators that can provide a more holistic view of their health. That being said, body fat percentage is an easily quantifiable metric that can give you a good idea of what it will take to achieve your fitness goals. If nothing else, it’s a friendly benchmark for your weight loss journey!
Managing weight and body fat is a big part of controlling the symptoms of diabetes. Living with this medical condition creates issues with regard to obesity and this results in a lack of good flow of insulin. Maintaining body fat ensures the right distribution of fat across the body parts and provides protection to the organs.
There are several different natural and activity-based ways in which the body can burn fat. Strength training exercises, a high-protein diet, well-rested sleep, consumption of healthy fats as opposed to unhealthy fats, drinking a lot of water, eating more fiber, etc.
Health-wise, it would be safe to lose about 0.5% of the total body fat per week which means 2% of the overall body fat per month. You can keep a track of this at home by measuring your height and weight and calculate the body fat %
