How 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 your muscle-building meals, we’ve broken down everything you need to know about training to build muscle mass to get you on the right track.

How to gain weight

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 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.”


Chris and his stuntman Bobby chow down on yet another meal to fill out the Thor costume.

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 high-protein smoothie recipes to help you gain weight (without feeling like you’re constantly eating).

Muscle-building foods to gain weight and muscle

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 fibre. 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, 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

Foods 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 snack often and opt for nibbles that combine two or more food groups – for instance, dipping apple slices in peanut butter.

Try adding these Centr snack recipes into your regular rotation.

High-calorie shakes for weight gain

In the best diet for weight gain and muscle building, protein shakes are the secret weapon. That’s because the amount of calories required to maximize muscle mass can make it feel like you’re constantly eating. So when you couldn’t possibly eat anymore, drink!


Getting some of your calories from smoothies and shakes can make gaining weight easier – especially when they taste as good as the Green Super Smoothie.

Using protein powder in high-calorie shakes for weight gain is one of the easiest ways to boost your daily intake. Smoothies are especially useful as a post workout meal to get your protein fix, or as a quick bulking breakfast you can grab and go.
