Why It’s Hard to Get Below 10% Body Fat

Getting below 10% body fat is harder because a smaller calorie margin, more hunger, and reduced energy can make the final stretch difficult to sustain. In my experience, the tradeoffs become much more noticeable than they were around 15%.

This FAQ is for men considering that final stage of a cut. It covers food tracking, lifting, hunger, plateaus, and whether getting that lean fits your training goals. Single-digit body fat is not a requirement for health or athletic performance.

My comparison at 6 ft tall: 202 lb on the left and 182 lb on the right, at approximately 15% and 8–9% body fat. The percentages are estimates.

Why is it so hard to go from 15% to sub-10% body fat?

Metabolic adaptation: As you lose weight, a smaller body generally uses less energy, and energy expenditure can also adapt during a sustained deficit. The calorie intake that worked earlier in the cut may no longer create the same deficit. There is no universal 15% threshold where this suddenly starts.

Increased hunger: In my experience, the final stretch below an estimated 10% is much hungrier than getting to around 15%. How much hunger you experience varies.

Energy dips and fatigue: Lower body fat can lead to reduced energy levels, impacting daily activities and workouts. You won’t believe how awful your workouts feel in the last few weeks of a cut when you are in the single digits for body fat.

Consistency and tradeoffs: The final push takes more attention to food, recovery, and training. Deciding the cost is too high is a valid choice.

Greater attention to detail: Smaller tracking errors matter more when progress is slow. Review portions, cooking fats, sauces, and snacks before assuming you need a more aggressive deficit.

Hormonal changes: Hormones that regulate appetite and metabolism, such as leptin and ghrelin, may shift unfavorably, making fat loss more difficult. Translation: the leaner you get while in a deficit, the shittier you’ll feel.

What does 15% body fat look like?

At 15%, you’ll likely have some visible muscle definition (especially in arms and chest), but still a bit of softness in the belly or love handles. You likely can just barely see your abs when relaxed and can kind of see them when flexing but they don’t look that great.

For more examples, see my photos at approximately 15%, 10%, and 7% body fat. These are estimates, not a way to measure body fat precisely from a picture.

Why does fat loss slow down at lower body fat levels?

As you get leaner, your metabolism slows, making it harder to lose fat. You either have to cut calories more (I don’t recommend going much lower than 10x body weight in pounds) or increase expenditure (low-intensity cardio is your friend here).

How should I eat to get leaner without losing muscle?

Protein: 1g/lb of bodyweight

Carbs: Carb cycling can help—have higher-carb days around workouts and lower-carb days when you’re less active. Timing carbs around workouts is a huge one for me when on a cut.

Fats: Keep fats low to moderate to support hormone health, no lower than 30% of body weight in grams. (If you weigh 200, no lower than 60g of fat per day)

Example for a 200-pound male: 200 g of protein, 70 g of fat, and 200 g of carbs total 2,230 calories. This is an example, not a universal calorie target.

The more low intensity cardio you do, the more carbs you can eat.

How can I deal with hunger during this phase?

It will be a near constant once you get close to 10%.

High-volume foods can help, but how closely you log them depends on your situation. Here is when to count vegetable calories.

Here are a few things that can help:

• Increase protein and fiber intake for satiety—lean meats, vegetables, and whole grains.
• Drink more water throughout the day. I’m a huge fan of diet soda. Keeps you hydrated and satisfies the sweet cravings a bit.
• Eat high-volume, low-calorie foods. Some of my favorites are air-fried potatoes and Brussels sprouts.
• Consider intermittent fasting to manage cravings by limiting your eating window. I typically only eat from ~1pm-7pm when on a cut.
• Stop using protein powder. When cutting this low, you need to be maximizing your intake of real, whole foods. Don’t use any powders or bars.
• Refeed days: A planned higher-calorie day can provide a mental break, but it is not a guaranteed reset of hunger hormones. Keep it structured. Read my experience with refeeds.

Do I need to do tons of cardio?

No, but you should. The key is keeping the intensity low. Doing HIIT during a cut is a terrible idea.

What’s the best way to break a fat loss plateau?

Plateaus will happen and exactly how it happens can vary from person to person. For me, once I get near or below 10%, my weight typically won’t move for 3-5 days then will drop 2-3 pounds in 1-2 days. It’s like it’s fighting me and then finally gives up. It’s annoying, but I’ve learned that’s how my body does it so I know what to expect.

 If you hit one, here are some things to try:

• Check the trend first. A few flat days are not enough to establish a plateau. Compare weekly average weight, waist measurements, and adherence over multiple weeks before making another change.
• Adjusting your calories or activity levels slightly. A 5-10% calorie reduction or adding an extra cardio session or a few thousand more steps is a good starting point. But don’t do this too quickly!
• Review your food log: Check hidden calories from oils, sauces, and snacks, along with serving sizes and raw-versus-cooked entries.
• A planned maintenance break: Spending time at maintenance may make a long cut easier to manage. It does not guarantee a metabolic reset or faster subsequent fat loss. I have not personally used this approach. A randomized trial in resistance-trained women found no improvement in resting metabolic rate or body composition from diet breaks compared with continuous restriction; that specific study does not settle the question for every athlete.

What kind of training is best for getting lean?

Strength training is mandatory but you probably don’t need to do as much as you think you do to maintain mass. 3 days per week of low to moderate volume is plenty for most people. 

Low-intensity steady-state (LISS) cardio is easier on muscle retention and good for longer sessions. You can basically do as much as you want or can handle. Walk, bike, elliptical, whatever you like to do, do a lot of it and keep the HR low, generally 110-120bpm is plenty.

How do I know if I’m making progress?

Pictures, body weight, and body measurements (specifically the waist).

You should track weight every day, waist every week, and pictures as often as you want.

If your pants are getting looser and your waist measurement is decreasing, those can be signs of progress even when daily scale weight fluctuates.

How long does it take to get below 10% body fat?

There is no fixed timeline. Your starting point, muscle mass, calorie deficit, adherence, and recovery all affect it. A visual body-fat estimate is too imprecise to promise a finish date.

Use weekly weight averages, waist measurements, comparable photos, and training performance to judge the direction of travel. If hunger, fatigue, or declining performance make the plan unsustainable, reconsider the target instead of forcing a deadline.

Is getting below 10% worth it for a hybrid athlete?

It depends on the goal. In my body-fat photo guide, I describe feeling good around an estimated 10–11%, while 7–8% brought more hunger and worse training. Those are my experiences, not universal cutoffs.

Visible abs are not the only useful measure of progress. Consider your running, strength, recovery, sleep, and enjoyment of food alongside appearance. You do not need to maintain single-digit body fat to train as a hybrid athlete.

If you choose to try it, good luck!

It is hard, and whether the tradeoff is worth it depends on your goals and how you feel.
