What to eat to gain weight and muscle mass

Centr Team

If you want to build muscle and gain weight, shakes are the best way to do it… Is that right? Wait, someone else says that to gain weight, foods such as chicken and steak are best. No, that can’t be it...

When every lifter in the gym has their own secret recipes for weight gain, or wants to tell you about the ‘best bulking meal ever’, it’s hard to know what advice to listen to. That’s why we want to break down the essentials for any healthy meal plan to gain weight and muscle, from what to eat before a workout to fuel your body to what to eat after a workout to gain weight, all so you can achieve your muscle-building goals.

So before you crack on with that post-workout meal, we’ve broken down everything you need to know about the best foods to gain muscle mass and training to get you on the right track.

How to achieve your weight-gain goals

It’s important to factor in your personal goal, calculate your individual calorie needs, follow a muscle-building program that uses progressive overload and compound exercises, and prioritize recovery and sleep.


Just like you go to the gym every day and monitor your form, you need to stay on top of your nutrition and monitor your outcomes.


Chris Hemsworth and his personal trainer Luke Zocchi have designed the definitive muscle-building program Centr Power, inspired by the training they used to prepare for the latest Thor movie. They have refined their process over the years, and this includes planning nutrition for a muscle-gain diet just as carefully as they plan workouts.

What does a muscle-building diet look like for these guys? It includes a lot of variety, and small meals spread out across the day. Yet Luke’s biggest tip is not to simply eat like Chris Hemsworth, but to adapt to your own needs and be consistent: “Just like you go to the gym every day and monitor your form, you need to stay on top of your nutrition and monitor your outcomes.”

So while you’re carving out time to go to the gym, you should also be doing some meal planning in the kitchen. Meal prepping doesn’t have to be a headache. Your meal prep could be as simple as planning and shopping for a week of meals in advance, batch cooking several meals on the day you have time, or stocking your freezer with dinners for those nights you’re late home from training.

Whether you’re starting a muscle-building program, or fine-tuning your nutrition to perform better, we’ve got the tips you need to maximize your results. We’ll also share a few of our favorite quick and easy muscle-building recipes, plus smoothie recipes destined to become one of your go-to sources of protein.

Muscle-building foods to help you gain weight

Any meal plan or diet to gain weight and muscle should include a range of healthy whole foods, with plenty of protein to aid muscle growth and colorful veggies for nutrients and fiber. For Chris and Luke, a regular meal will have a macro breakdown of around 30–40% protein, 30% carbs and 30% fat.

In your daily meal plan to gain weight and muscle, aim to include foods such as:

  • Fish

  • Lean meat

  • Chicken

  • Starchy carbs (e.g. potato, corn, grains)

  • Oats and whole-grain bread

  • Rice

  • Pasta

  • Dairy in the form of milk and Greek yogurt

  • Tofu and tempeh

  • Legumes

  • Nuts and nut butters

  • Seeds

  • Eggs

Extra calories to avoid when you want to gain weight

When you’re thinking about what to eat to gain muscle mass, sweets such as soda/soft drinks and candy, or fast food may seem like the easy route to get the calories you need – a no-effort way to stack on weight fast.

But while these foods may be high in calories, they’re not the kind you want. Known as ‘dirty bulking’, this kind of ‘eat whatever you want that is high in calories’ bulking plan is more likely to expand your waist with fat than it is to build up your muscles with protein.

Bulking snacks for building muscles: How to top-up when you’re trying to gain weight

Most people following a muscle-building program find that eating regular snacks throughout the day is easier than sitting down for enormous high-calorie meals three times a day. So rather than focusing only on your post-workout meal for muscle gain, snack often and opt for nibbles that combine two or more food groups – for instance, dipping apple slices in peanut butter.

Top muscle-building workout advice

We can’t talk about how to gain weight and muscle without mentioning your training.

If you want to build muscle effectively – without spending endless hours in the gym – compound movements that work several muscles at once should be a priority. By varying your form on this style of exercise, you can shift the emphasis to different muscles.

Good examples of compound movements are:

  • Squats – engages your quads, hamstrings, calves, glutes, core and lower back.
  • Bench press – works your chest, shoulders and triceps.

“Any muscle-building program worth your time is going to focus on those big compound moves,” says professional bodybuilder and Centr expert Torre Washington. “Because compound exercises are multiple joint movements, they allow you to work different muscle groups all at once.”

If you’re new to building muscle, check out Torre’s rules for getting started.

The other essential element of building muscle is progressive overload – regularly increasing load and training intensity so your muscles are forced to adapt and get stronger. In the main, this means gradually increasing the weight you’re lifting each week. But you can also challenge your muscles by increasing reps and sets, and switching tempo to increase time spent under tension.

Consistency and repetition is also key to getting results – that means having a solid lifting schedule. Whatever your experience level, the 13-week Centr Power program will help you master lifts and lock in a routine to maximize muscle mass.

You can choose to train in the gym, or follow the home program.

So what should you eat to gain weight?

There’s no secret recipe or magical weight-gain foods that will instantly give you the size you’re looking for.

Take these rules with you to create a sustainable plan and be consistent: the results will come.

To gain weight

  • You need to be in calorie surplus – but avoid ‘dirty bulking’ which is more likely to expand your waistline than your muscles.

  • Eat a variety of foods, spread out in small meals across the day.

  • Follow a personalized muscle-building program to get results. You don’t need to be the heaviest lifter in the gym – start at a level that’s right for you.

  • Leave enough time for rest and recovery.

Foods to aim for

  • Protein-rich foods like fish, lean meat, chicken and eggs

  • Starchy carbs like potatoes, corn, grains, rice and pasta

  • Dairy in the form of milk and Greek yogurt

  • Seeds, nuts, and legumes

  • And when you feel like you can’t possibly eat anymore, drink instead – smoothies are your friend!
