You want to build muscle and lose fat. But should you try to do both at the same time (recomposition), or should you focus on one at a time—either cutting (fat loss) or bulking (muscle gain)?
The answer depends on your training experience, age, and gender. Let’s break it down.
When Recomposition Works Best
Recomposition—gaining muscle while losing fat—works well for three groups of people:
- Beginners – If you’re new to strength training (or coming back after a long break), your body is highly responsive to lifting weights. You can build muscle and burn fat at the same time, especially if you’re eating enough protein and lifting consistently.
- People with Higher Body Fat – If you have a good amount of fat to lose, your body can use that stored energy to help fuel muscle growth. A small calorie deficit, combined with strength training and enough protein, can lead to noticeable changes in both fat loss and muscle gain.
- Detrained Lifters – If you were in great shape before but stopped training for a while, your body can "remember" past muscle and rebuild it quickly, even in a calorie deficit.
If you fit into one of these categories, recomp might be a great option. Keep your protein intake high (around 0.8–1g per pound of body weight), strength train at least 3-4 times a week, and stay in a slight calorie deficit (or maintenance).
When to Focus on Fat Loss
If your main goal is getting leaner and you don’t fit the ideal conditions for recomposition, a dedicated fat-loss phase makes more sense.
Fat loss works best when:
- You’ve been training for a while – Experienced lifters have a harder time building muscle in a deficit, so they’ll get better results by focusing purely on fat loss first.
- You’re at a higher body fat percentage – If you’re 20%+ body fat (men) or 30%+ (women), a focused fat loss phase will give you better results.
- You want to see progress faster – Recomp works, but it’s slow. If you’d rather see noticeable fat loss in a few months rather than small changes over a year, a dedicated cut is better.
The key here is eating in a moderate calorie deficit (300–500 calories below maintenance), lifting weights, and keeping protein high.
When to Focus on Muscle Gain
If you’re relatively lean and have been lifting consistently, you’ll probably need to enter a muscle gain phase (bulk) to keep progressing.
Muscle gain works best when:
- You’re at a lower body fat percentage – If you’re already lean (under ~15% body fat for men, ~25% for women), eating more will help you build muscle without unnecessary fat gain.
- You’ve hit a plateau in strength/muscle growth – If you’re struggling to increase strength in the gym, you probably need more food to support muscle growth.
- You’re an experienced lifter – The more years of training you have, the harder it is to build muscle while losing fat. A calorie surplus makes it easier.
For a successful muscle-building phase, eat 100–300 calories above maintenance, train hard, and prioritize progressive overload. Keep fat gain in check by monitoring weight gain—aim for 0.5–1 pound per week.
How Age and Gender Affect Your Approach
- Age – Younger people can typically recomp more easily, thanks to higher testosterone levels, better recovery, and faster metabolism. As you age, it becomes harder to gain muscle in a deficit, so focused fat loss or bulking phases work better.
- Gender – Men generally have an easier time with recomp because of higher testosterone levels and other hormonal advantages that support muscle growth. Women, especially those who have been lifting for a while, may find it harder to build muscle while losing fat and may need to choose between bulking and cutting for optimal progress.
How to Tell If Your Diet Is Working
No matter which phase you’re in, you need to track progress. Here’s how:
✅ Recomp – You should see slight strength increases in the gym while body measurements (waist, arms, legs) shift over time. The scale may not move much, but progress photos should show more muscle definition.
✅ Fat Loss – The scale should be trending down (around 0.5–1 pound per week), and you should see noticeable changes in measurements, photos, and how clothes fit. Strength might dip slightly, but it shouldn’t crash.
✅ Muscle Gain – Your weight should be increasing slowly (0.5–1 pound per week), your lifts should be improving, and measurements for arms, chest, and legs should be going up while waist size stays relatively stable.
If nothing is changing after 3–4 weeks, adjust. Either eat slightly more or less depending on your goal.
