gaining muscle but not losing fat
Gaining muscle but not losing fat? Don't get frustrated! You probably just need to make some subtle changes.

Sometimes, working out and watching what you eat just isn't enough.

I know it's frustrating. You're working hard to build muscle, but your physique looks no closer to the image you have in your head.

The muscle just isn't showing through.

You’re not alone, believe me! I've been there, and so have thousands of other men who've joined the Fit Father Project.

The problem is that gaining muscle requires MORE food and losing fat requires LESS food.

It sounds counter-intuitive that you could do both at the same time.

If you find yourself gaining muscle but not losing fat, you may need to hack the system and go against nature.

The good news is that it is possible!

How many calories does it take to build muscle? This video will teach you how to calculate YOUR daily calories for muscle building.


The Science Behind Muscle Gain


Muscles get bigger when you use them.

If you push them to their limits, then you will cause tiny tears in the fibers of your muscles.

This is a good thing.

Your body will heal these tears, making the muscle stronger and bigger in the process.

This is why it’s essential to do strength training. Building muscles requires intense physical stress.

But that doesn't mean you have to spend hours in the gym.

The most efficient exercises are ones you can do at home with a pair of dumbbells or a kettlebell.


It is important to make sure that your body has enough protein to complete protein synthesis.

When you’re lifting weights, it’s recommended that you consume between 1.2 and 1.5 grams of protein per kilogram of your body weight.

You should be able to do this through the food you eat, but it is possible to take a protein supplement to ensure you reach your target on a daily basis.


You should also be aware that muscles should be rested for between 24 and 48 hours between workouts.

This gives them the opportunity to repair and grow stronger, allowing your exercise routine to be successful.

Understanding the Fat Loss Process

The other side of the coin involves losing fat.

The most basic way of burning fat is simply to consume fewer calories than your body needs to survive.

A calorie deficit will cause your body to convert the energy stored in fat cells into glucose for energy.

In the process, your fat cells will be depleted, reducing the fat levels in your body.

But a calorie deficit can also reduce muscle.

That’s why you need to eat enough calories to provide your muscles with the energy they need without overeating.

It can seem like a difficult balance, but it doesn't need to be.

If your current regime has you gaining muscle but not losing fat, you're probably almost there.

You may just need to change things up a bit.

Change Your Routine to Boost Fat Burning

So you know you need to eat more than your maintenance calories in order to encourage muscle growth.

You also know that you need to consume fewer calories than your body's energy requirements in order to burn fat.

While it may seem contradictory, these two goals can be achieved by adopting the right routine.


You should be doing some sort of strength training three times per week.

  • Bench press
  • Push-ups
  • Dumbbell squats
  • Weighted lunges
  • Deadlift
  • Tricep dips
  • Bent over rows

Add in moderate-intensity cardio three times per week, for between 30 minutes and an hour.

Choose something you enjoy, whether it’s cycling, running, or anything else that gets your heart pumping.


  • Make sure you’re getting enough protein in your diet. Experts recommend between 1.2 and 1.5 grams per kilogram of bodyweight.
  • Avoid processed food.
  • Consume some protein and carbs after your workout.
  • Fill up on fiber to keep you feeling satiated for longer.
  • Change your eating habits: Calculate the number of calories you need to consume each day and then eat between 200 and 300 less than that amount. Eat more than your maintenance calories, but less than the amount your body really needs for that day.
  • Get enough sleep. Your body needs time to rest, balance its hormones, and repair your body. You should aim for between 6 and 8 hours every night.

To help adjust your eating habits, it is beneficial to understand that this is a lifestyle change, not a diet.

Foods to Help Burn Fat and Gain Muscle

It’s important to note that building muscle will help with your fat-burning efforts, even if the scales aren't going down.

Muscle burns more calories at rest than fat does.

Having more muscle will increase your calorific burn and help you to burn fat.

Eating the right foods will help:

  • Eggs – They're full of protein, healthy fats, and vitamin Bs.
  • Salmon – A three-ounce serving has approximately 17 grams of protein! It also has omega-3 fatty acids and more vitamin Bs.
  • Chicken – The breast is also full of protein; about 26 grams in a three-ounce serving. Some studies have shown that a high protein chicken diet can help weight loss.
  • Greek Yogurt – As well as protein, Greek yogurts have fast-digesting whey protein and the slower digesting casein protein.
  • Lean Beef – Protein, B vitamins, minerals, and creatine are all present in lean beef. Quality is important if you’re choosing lean beef. 90% lean ground beef has 145 calories and 5 grams of fat. 70% lean ground beef is 228 calories and 15 grams of fat!
  • Shrimp – Most seafood is good for you, and a three-ounce portion of shrimp will give you 18 grams of protein, 1 gram of fat, and no carbs!
  • Soybeans – A great choice if you’re not keen on meat. Soybeans have plenty of vitamin K, iron, phosphorous, and 14 grams of protein per 86-gram serving.
  • Cottage Cheese – With 28 grams of protein in a 226-gram serving, this is a great way to boost your protein intake without significantly increasing carbs and calories.
  • Peanuts – One 73-gram serving has 17 grams protein, 16 grams carbs, and plenty of unsaturated fat. A small serving every day is a good way to boost your nutrient levels.

If You're Gaining Muscle But Not Losing Fat

There are several common mistakes that you need to avoid if you want to boost your muscle growth and burn fat. If you find yourself gaining muscle but not losing fat, you could be making these mistakes.

Mistake 1: Not Getting Enough Sleep

The importance of sleep cannot be stressed enough.

If you're not sleeping well, do something to change it.

Here are a few tips to get more sleep:

  • Get blackout curtains
  • Lower the temperature of the room
  • Use background noise (box fan, air purifier, or even a noise-producing phone app)
  • Go to bed earlier (duh!)
  • Avoid blue light before bedtime (cellphones, laptops, TVs, etc.)

Mistake 2: Not Eating Enough/Improper Balance of Macronutrients

In order to give your muscles the fuel they need to grow, you need to eat more than your maintenance calories.

Of course, everything you eat should be healthy food.

You need a balance of carbohydrates, proteins, and fats to give your body the fuel it needs to complete your exercises and repair muscle.

Mistake 3: Eating Too Much

Eating more than your maintenance amount doesn't mean you should eat everything in sight!

It is important to be aware of your maintenance calorie amount and how much you need to build the muscle you’re seeking.

This is the maximum calories you consume per day.

Eating more than your maintenance amount while working out regularly will simply make you gain muscle and fat.

Mistake 4: Eating At The Wrong Times

Before and after exercise are the most important times.

If you don’t have enough carbohydrates during this period, then your body could break down your muscles with the hormone cortisol, which creates glucose for energy.

You need to consume enough carbohydrates to provide your body with fuel, without overdoing it.

It’s a good idea to start a food diary.

Recording everything you eat will help you to see when and where you are overeating.

After a few weeks, you’ll be able to refine your eating plan and even start preparing your meals in advance.

Having a proper account will help you to consume the right number of calories and balance your carbohydrates, proteins, and healthy fats.

Pro tip: Don't feel obligated to eat if you're not hungry. Intermittent fasting is one of the best ways to burn fat.

See the program 38,000 guys over 40 are using to get results like these

Mistake 5: Eating Processed Foods

All macronutrients are important.

You should be aiming for every meal to have ¼ carbs, ¼ protein, and ½ vegetables.

This is known as the perfect plate method.

Portioning out your plate with a good balance of whole foods is the simplest way to make sure you're getting enough carbs, protein, and fat.

The important thing to remember is that not all carbs are created equally.

Processed carbs are easily absorbed, so won’t keep you feeling full for very long.

Processed carbs also cause blood sugar levels to spike, which encourages fat storage.

Refined carbs will release energy more slowly and keep you feeling fuller.

You should also be aware that processed foods tend to be high in sugar and other artificial additives.

When you’re looking to build muscle and burn fat, you want to minimize sugar and know exactly what you are putting into your body.

This isn't possible if you consume processed foods.

Mistake 6: Consuming Too Much Fat

Some fat consumption is essential for the health of your body, even when you’re trying to lose weight.

The problem is that fat is more calorie-dense than protein and carbohydrates.

At approximately 9 calories per gram, fat has more than double the amount of energy.

The trick is to keep your fat consumption to between 20-30% of your overall consumption.

Mistake 7: Not Getting Enough Protein

Protein is the building block of cells in your body.

In fact, it is an essential ingredient in repairing your muscle cells.

Tiny tears in your muscles are caused when you work out.

The repair process is what makes them stronger and bigger.

You don’t need to go mad on protein, but you do need to consume enough to provide your muscles with the nutrients they need.

Mistake 8: Not Training Hard Enough

If you're serious about gaining muscle and losing fat, you need to weight train two or three times a week, and it needs to be intense.

You have to strain your muscles, causing the micro-tears mentioned above, and allow them to grow.

It is important that you push your limits while weight training.

You should be aiming for 3 sets of 8 reps for most lifts.

The last reps should be almost impossible to complete.

If you can easily do all three sets then you need to increase the weight.

Mistake 9: Doing Low-Intensity Cardio

Cardio training is essential for burning fat, provided it is at the right intensity.

You should aim for between 30-60 minutes at a time and, again, two to three times a week.

Anything longer than an hour will encourage your body to break down muscle cells for food.

Final Thoughts

It’s worth remembering that everyone is different.

The secret to avoiding gaining muscle but not losing fat is to keep it varied.

It’s OK to take a few days off training, to switch it down, or up.

Changing things up will prevent your body from becoming accustomed to the workout, which is likely to cause it to lose its effectiveness.

Perhaps the most important tip we can give you is to join Old School Muscle and get the support you need to keep working towards your goal.

You can become the man you want to be!
