Frequently Asked Questions


Reducing body fat percentage means decreasing the total fat in your body. To lose one pound of fat, your body needs to burn 3,500 more calories than you consume, which means that to lose one pound of fat per week, you should reduce your daily calorie intake by 500 calories (or burn these calories through exercise), according to the U.S. Department of Agriculture (USDA). Lowering your body fat percentage will likely involve reducing the number of calories you consume, in addition to increasing your physical activity level.

A registered dietitian or nutritionist can help you design a safe, nutritious, and sustainable meal plan that reduces your daily calorie intake to achieve your weight goals - but without being overly restrictive. While popular diets may lead to initial weight loss, research suggests that they are difficult to maintain in the long term due to their strict nature and tendency to eliminate entire food groups.

There are many ways to make changes in your eating habits with high levels of physical activity to support fat reduction in the body. Studies indicate that 30 minutes of aerobic exercise per day is associated with sustained weight loss. Aerobic exercises can take many forms, including walking, running, swimming, and/or cycling, and should be based on your physical fitness level.

In addition to reducing calorie intake and increasing exercise, relatively recent evidence suggests that engaging in weight lifting exercises also has a positive effect on body fat percentage. A large systematic review of studies in the Journal of Sports Medicine for 2022 showed that weight lifting effectively reduces body fat percentage, including abdominal organ fat.

Body Mass Index (BMI) is a basic calculation that divides a person's weight in kilograms by the square of their height in meters. Simply put, BMI classifies individuals as underweight, normal weight, overweight, or obese, according to Atkinson, noting that many of her very lean professional athlete clients would be considered obese based on their BMI.

A quick and easy calculation, BMI essentially categorizes individuals as underweight, normal weight, overweight, or obese, according to Zarrabi. "It does not give us a complete picture of your epidemiological health, [and] it is not the most accurate to classify your health status because it does not take into account how much of your total body weight is actually muscle," she says. "Body fat percentage is always a better indicator."

Regular exercise and following a calorie-specific healthy diet can prevent excess fat accumulation in the body.

BMI can be a quick way to assess your risk of epidemiological diseases, in addition to knowing your weight classification, according to Zarrabi. "If you find yourself with a high BMI or outside the range, it may also be best to test your body fat percentage," she says.

Consider testing body fat percentage if you notice an unexplained weight gain of at least 10 pounds in six months, recommends Atkinson, adding that everyone should have an annual check-up to assess their overall health. If your body fat percentage is high, your doctor can discuss how to reduce it during these appointments.

Finally, it's important to remember that body fat percentage is just one marker of health - rather than fixating on the number, focus on your daily lifestyle habits, says Zarrabi. "We need to assess our sleep hygiene, stress levels, outlook on life, dietary behaviors, and movement patterns as well," she says.
