Across the board, one of the most common goals our clients share is trying to figure out the best way to lower body fat percentage. 

It's important to remember that losing fat doesn't mean getting rid of body fat completely. You need to have some body fat to maintain your health.

So, when we hear our clients ask, "what is the best way to lower body fat percentage" we know that the goal they're after is improving body composition. This typically means lowering body fat while increasing lean muscle mass.

Losing body fat may help you achieve the slimmer, toned look that you're after. If you're at an unhealthy body fat percentage, dropping some weight can also help increase your energy, performance, and confidence.




How Does Body Fat Affect Your Health

Before we jump into the best way to lower body fat percentage, let's take a look at how body fat affects your health and what a healthy body fat percentage looks like.

Main Types of Body Fat

There are three main types of body fat: 

  • Essential fat
  • Subcutaneous fat
  • Visceral fat

What is Essential Fat?

Essential fat is the amount of body fat that's necessary for your survival. This type of fat provides insulation to help keep you warm, protects and cushions your organs, and allows you to absorb certain vitamins.

What is Subcutaneous Fat?

Subcutaneous fat is the fat that lies directly underneath your skin's surface. When you talk about fat, this is the type you're probably thinking about.

What is Visceral Fat?

Visceral fat is a deep type of fat that surrounds your organs. You can't see visceral fat, but it's the most dangerous type of body fat because it's biologically active, which means it can produce hormones and other substances that affect your health. Visceral fat is connected to insulin resistance and metabolic diseases, and it can shorten your lifespan [1].

While subcutaneous fat may be your motivation behind wanting to lose some body fat, visceral fat is most concerning. The good news is when you lower your body fat percentage, you lose some of both types.

Keep in mind that while too much body fat is more of a widespread concern, having a really low body fat percentage comes with its own set of health problems, like:

  • Increased risk of vitamin deficiencies, especially the fat-soluble vitamins A, D, E and K
  • Decreased muscle mass
  • Heart problems
  • Brain and nervous system disorders



What is a Healthy Body Fat Percentage?

Now that you know the health risks associated with having too much or too little body fat, the next question is, “What's a healthy body fat percentage?” You might even be wondering, “What should my body fat percentage be? Is there a magic number I should aim for?” 

Healthy body fat percentages are given in ranges and differ between men and women. Let's break them down:

Healthy Body Fat Percentages for Women

A healthy body fat percentage for women is between 25-31%. Anything over 32% body fat for women and is classified as obesity [2].

That being said, women who are physically fit and have a higher muscle mass typically have body fat percentages between 21-24%. 

Healthy Body Fat Percentages for Men

A healthy body fat percentage for men is between 18-24%. Anything over 25% is considered to be obese [2].

Just like women, men who exercise more and carry more muscle will typically sit at a lower body fat range. For them, this range is around 14-17%.

When Is It Safe To Lose Weight?

There are times when your body is primed and ready for weight loss. Here are a few situations when it is safe to lose weight:

  1. If you are at or above the obesity percentages we shared above
  2. If you have been eating at calorie maintenance or surplus for a prolonged period of time (wondering what this means for you? A 1:1 online nutrition coach can give you specifics based on your body and goals!) 
  3. If you're in the "healthy body fat percentage" range and want to lean out a bit more (this is even easier if you're new to strength training!)
  4. For women: because calorie deficits and weight loss can impact your hormone levels more than we typically see in men, it is safe to lose weight when you are regularly cycling and have an all-clear from your OBGYN!

When Is It Unsafe To Lose Weight?

It is possible to lose too much weight.

Remember, essential body fat is the minimum amount of body fat you need to stay healthy. For women, this is around 10-13%, and for men, it's considerably lower at 2-5%. We recommend staying away from these percentages [2].

Some times it may be unsafe to lose weight are:

  1. If you are below the "healthy" or "physically fit" levels we shared above
  2. If you have been eating at a calorie deficit for a long period of time and are not seeing any changes in weight or body composition
  3. If you are losing weight at a very quick rate and are noticing major changes in your energy, mood, performance, sleep, and stress
  4. For women: in most situations, losing weight during pregnancy is no recommended. It may also be a sign it is unsafe to lose weight if you've been dieting and lost your cycle.

Body Fat Percentage vs. Body Mass Index

“BMI” (or, body mass index) is a concept that has been around for a while. Many people wonder if BMI is the same as body fat percentage. Before jumping into how to measure body fat, we need to quickly discuss the difference between body fat percentage and body mass index, or BMI.

Your body fat percentage is a measure of how much of your body weight exists in the form of fat.

Your body mass index is a way to figure out if you're at a healthy weight for your height. While some people say that you can determine whether or not you have too much body fat by calculating your BMI, it's not really an accurate measure of body fatness or even overall weight status.

Because BMI only uses your height and body weight, it can't effectively measure body composition. This is especially apparent for people who have a lot of muscle mass, like bodybuilders.

Bodybuilders may weigh more than other people who are the same height because they have more muscle and lean body mass, which is denser and can lead to higher numbers on the scale.

If you want an accurate picture of your percent body fat, you have to measure it directly. 



How to Measure Body Fat

The quickest way to measure body fat at home, or at your gym, is with skinfold calipers. Calipers measure the thickness of your skin, including the underlying fat mass, to give you an idea of the amount of body fat you have.

There are other ways to measure body fat too, but you can't do them at home. You have to find a fitness center or a medical center near you that provides these services.

Some other ways to measure body fat are:

  • DEXA scan
  • Hydrostatic weighing
  • Bioelectrical Impedance Analysis (BIA)
  • Bioimpedance Spectroscopy (BIS)
  • Air Displacement Plethysmography (Bod Pod)
  • Electrical Impedance Myography (EIM)
  • 3D Body Scanners

Keep in mind that while these methods sound really fancy, they're not that superior to using regular old skinfold calipers. To put it into perspective, skinfold calipers have an error rate of 3.5% to 5% [3] while DEXA scans have an error rate of about 4% [4]

That's why you should consider any body fat measurement as a way to observe trends in your body composition and measure overall progress instead of getting hung up on the exact number.

How to Lower Body Fat Percentage

If you've gotten your body fat percentage tested and it's higher than you'd like to see, or you're just not feeling like yourself lately and you want to do something about it, the next step is figuring how to lower your actual fat levels. 

It is important to keep in mind that this is just one piece of information. You can use it to assess whether or not the efforts you put into fat loss are working or if something needs to change or adjust. But, it isn’t the only measure of progress.

Just like the number on a scale is part of a bigger picture, your current body fat percentage is also just a number. 

Connecting back to other factors like how you feel in the gym, increases in energy, food quality, changes in measurements, and how your clothes fit are all other measures of progress to keep an eye on through your journey.



1. Try High-Intensity Interval Training for Fat Loss

High-intensity interval training, or HIIT, involves alternating short bursts of high-intensity exercise with slightly longer periods of low-intensity exercise.

The goal is to spend 20 to 90 seconds working as hard as you can to increase your heart rate and then back off a little to allow for a quick recovery before you rinse and repeat. 

Research shows that HIIT can increase your metabolic rate and reduce both subcutaneous fat and belly fat better than other types of exercise, including moderate-intensity training and aerobic exercise [5, 6].

For optimal fat burning, try to do some HIIT workouts a few times per week. If you're new to the concept of HIIT, a personal trainer can show you the way.

2. Resistance Train for Fat Loss

Along with high-intensity interval training, you'll also want to incorporate resistance training, aka strength training or weight training, regularly. 

Resistance training can help improve your body composition by helping you build muscle and lose fat at the same time. 

In one study, a group of overweight women was instructed to start resistance training, with resistance bands, three times per week. After a 12-week period, the women lost a significant amount of overall body fat and belly fat without any muscle loss [7].

When compared to other types of exercise, resistance training also has a higher excess post-exercise oxygen consumption, or EPOC, for short. This means that your metabolism may stay higher for longer after weightlifting, so you can burn more calories even after your workout is over [8].

When you gain muscle, it can increase your resting metabolic rate, or RMR, which means you burn more calories, even when you're not doing anything.

3. Eat at a Calorie Deficit (& Hit Your Macros Consistently)

You may have heard “you can’t outrun your fork” or that fitness is 20% exercise and 80% nutrition. Those percentages aren’t exact — they’re just part of the saying — but the point is that lowering body fat percentage requires a balance between exercise and food.

While regularly hitting the gym is an essential part of improving your body composition, spending an hour or two working out every day won’t offset constant hours of snacking and eating meals. Think about it, you spend 1-2/24 hours in the gym. The rest of that time, you’re either sleeping or in an environment with tons of treats and temptations that are easy to grab.

If you want to accelerate fat loss, it’s important to hit your macros — or carbohydrates, protein, and fat recommendations — consistently.

Macros are based on your caloric needs, so when you prioritize hitting them, you naturally stay on the right calorie diet for you. This will prevent you from taking in extra calories that can make it harder to burn fat.



4. Focus on Micronutrient-Rich Foods

One of the really great things about flexible dieting is that it’s, well, flexible. There’s a lot of room for you to eat all of your favorite foods while still staying within your macros. 

But if you’ve noticed a stall in your progress or you just really want to dial it in, try to focus on including as many micronutrient-rich foods into your meal plan as possible.

In other words, choose foods with high amounts of vitamins, minerals, and antioxidants over foods that don’t have as much to offer in that department. 

This will naturally lead you to choices like fruits, fiber-rich vegetables, lean proteins, and slow-digesting carbs that keep you full and balance your blood sugar, while also helping to slim you down. 



5. Manage Your Stress Levels

It's not all about dieting and exercise, though. Your body composition also has a lot to do with your mental health and the way you handle stress. 

When you're stressed out all the time, it increases the amount of cortisol in your blood. High cortisol levels can make you store more body fat, especially in the form of belly fat [14].

While it's impossible to get rid of stress completely, you can become more resilient to the effects of stress by regularly practicing things like yoga, meditation, and deep breathing. 

Learning how to say "no" and making sure you have a good work-life balance are also critical to healthy stress levels.

6. Get Enough Sleep

Sleep plays an imperative role in weight maintenance. There have been several studies linking getting less than seven hours of sleep per night with a higher body fat percentage [15]. 

When you don’t get enough sleep, the resulting low energy causes you to move less throughout the day. This makes it much more tempting to skip your workout, and your NEAT (non-exercise activity thermogenesis) naturally decreases as well. This decreases overall calorie burn throughout your day.

Lack of sleep also triggers a spike in your stress hormone, cortisol. This triggers your body to conserve energy (aka, body fat). Your hunger and fullness hormones are also impacted. Your “I’m hungry” hormone, ghrelin, increases, and your “I’m full” hormone, leptin, decreases. This is a double-whammy when it comes to hunger. When you’re hungry, tired, and stressed, this is a recipe for overeating and putting on weight [16]. What can you do about it? Here are a few quick tips to help you increase your sleep quality:

  • Stick to a regular sleep schedule
  • Turn off electronics at least 30 minutes (preferably more!) before bed
  • Keep your room cool, dark, and quiet
  • Get more sunshine
  • Exercise regularly
