How to gain weight

The most important thing to gaining weight is creating a calorie surplus, meaning you eat more calories than your body consumes.

If you want to increase your weight slowly aim for 300-500 calories more then you burn each day. This should roughly translate to 0.7-1 pounds gained per week.

If you want to increase your weight fast, aim for 700-1000 calories more then you burn each day. This should roughly translate to 1.7-2 pounds gained per week.

To find out your daily maintenance calorie intake try this calorie calculator. This will give you a rough estimation of your maintenance level.

Note: Make sure to exercise regularly when on a weight gain diet to avoid putting on lots of fat.

How to get the most out of this weight gain smoothie

The best way to add this weigh gainer smoothie into your diet is to add it as your 4th or 5th meal. This way it will help you get a calorie surplus as you will still be having breakfast, lunch and dinner.

The best time to have this is between breakfast and lunch, lunch and dinner or after a workout.

It’s great after a high intensity workout as it has plenty of protein to rebuild muscles, carbohydrates to replenish glycogen and contains electrolytes and sodium.

Did I read this right, 800+ calories in one drink? I have a 6’7 155 pound 15 yr old. Zero fat! He was up to 170 but lost 15 pounds in one varsity basketball season. Metabolism is extremely high and an athlete year round. We try to get 4,000 calories a day in him, but am thinking we need to try for 6,000. I am very concerned about injuries with his body structure and weight. Would drinking this 3/4 times a day be ok? Or suggestions on other ingredients to add to each drink to get the calories over 1000 calories a drink and only having 2 a day?

His 17 yr old brother is 6’6 and 200 pounds. He also needs to gain weight, but not as extreme.

Jack, I have the PE protein powder. The label says 120g of powder per shake but I’m assuming that’s just with milk.

So my question is do I add the 120g or just the 50g?

Hey Aneesah, you can go ahead and add just 50g. The shake would become overly thick and powdery if you were to add much more.

Hi Jack, I am trying to help my son gain weight, but he is lactose intolerant and has peanut allergies. I plan on using sunflower butter to substitute the peanut butter, but what can I use instead of whole milk?I know this recipe will help him tremendously and are looking forward to using it! We appreciate your time!

@Kayli, there lactofree milk. I’m also lactose intolerant and this milk actually helps.

Hey Kayli,

It looks like you've had some great suggestions already!

Sunflower butter is an excellent substitute for peanut butter; it's packed with many energy-packed nutrients.

Oat milk and Soy milk are both great substitutes for whole milk too. Oat milk is higher in calories and carbs, and Soy milk is higher in proteins, fats, and calcium.

If you're planning on adding a weight gainer or protein powder, double-check that they are lactose-free because a lot of weight gain and protein powders use milk.

If you're struggling to find one, a safe bet is to use a vegan protein powder because lactose is only present in animals.

I hope this helps, Jack

@Kayli, Juat dont use the link to weight gain powder it contains milk


Sunday 30th of January 2022

@Kayli, you can use Oatly full fat milk instead of cow’s milk! It has 160 calories per cup. Hope this helps!
