In this article, I’ll discuss the concept of a “keto mass gainer” to see whether or not a ketogenic mass gainer is actually a thing.

One thing’s for sure, though: most people go on ketogenic diets to lose weight. So, if you’re trying to gain weight on a ketogenic diet, then you’re probably going to struggle.

But that’s certainly not to say that you can’t gain weight on a keto diet. It’s just that, when you eat carbohydrates, your appetite tends to increase, which makes gaining weight easier.

Is There Such Thing as a Keto Mass Gainer?

No, there is no such thing as a keto mass gainer in terms of supplements because mass gainers are characterised by their high carbohydrate contents, which makes them unsuitable for those following a ketogenic diet.

Most mass gainers contain at least 50 grams of carbs per serving, which would already blow your carbohydrate allowance for the day if you’re on a keto diet.

In fact, many mass gainers have 200+ grams of carbs per serving, making them the furthest thing away from a keto-friendly supplement.

Rather than taking a mass gainer, those following a keto diet should opt for a protein powder that has a good amount of fat, which is something that many weight gainers lack.

These high-fat shakes, though not technically mass gainers, can certainly help you gain weight if your body is in a calorie surplus. It’s this energy surplus, rather than a specific supplement, that determines how much weight you gain, if any.

How Can You Make a Ketogenic Mass Gainer?

You can certainly make your own moderate to high-calorie smoothies that are keto-friendly, as long as you keep a strict watch on the carbohydrate content.

For example, you could use low-carb plant milk as the base, which will be much tastier than water. From there, you can add in some keto protein powder with a good amount of fat. And to finish things off, you could add some avocado and/or a healthy nut butter of your choice.

Although the likes of avocado oil, olive oil, and coconut oil are popular among keto dieters, I wouldn’t add them to your keto smoothie because they’ll really affect the flavour.

Instead, stick to high-fat ingredients like almond butter, avocados, low-carb plant milk, and ketogenic protein powder.

Also, while you can definitely make keto pancakes to keep your diet interesting, you should steer clear of weight gainer pancakes, as they’ll cause you to overload on carbs.

Is The Keto Diet Good For Getting Big?

Since the keto diet is helpful for suppressing your appetite, it’s definitely not the best diet for building muscle and bulking. 

While many people have gained muscle on a keto diet, something which is proved by studies, those with at least some carbohydrates in their diet tend to have an easier time packing on mass than those who eat a very low-carb or zero-carb diet.

When your muscles are glycogen-depleted, you won’t have the same strength endurance, meaning that you won't be able to get as many reps per set, which ultimately makes for slower and less substantial muscle growth.

Not Optimal: While you can bulk on a keto diet, you'll likely make better bulking progress with some carbs in your diet.

So, while you can bulk on a keto diet, it’s definitely not the most efficient option. But there’s no harm in trying if you don’t feel like you respond well to a high-carb diet.

After all, there’s no one-size-fits-all diet that’s best for bulking—as long as you’re in a calorie surplus, you’re on the right path to gaining weight.

The Verdict On Keto Mass Gainers

So, as we established, a keto mass gainer is pretty much a contradiction in terms because weight gainers as a supplement category are, by definition, high in carbohydrates and low in fat.

Honestly, mass gainers are the furthest thing from a ketogenic supplement that I can think of. So if you’re following a keto diet or any other kind of low-carb diet, you should stay well clear of  mass gainers of all kinds because even half a shake is likely to make you consume too many carbohydrates.

You can, of course, get a keto protein powder that has a good amount of healthy fats. This is the closest thing to a “keto weight gainer” that you’re going to get, and it’s certainly an efficient way to get some extra calories in your ketogenic diet, especially if you don’t have a particularly big appetite.
