If you’re reading this, you are probably like me. I’m a skinny guy, and I have trouble gaining weight, even when lifting big and heavy. In under six months, I put on 15 pounds – from 145 to 160. This may not seem like a lot to some, but it was certainly a big deal for me! I wanted to offer help to others with this best weight gainer for skinny guys list.
I spent years getting very strong and even started looking much better, but I would stay about the same weight. This prompted me to start adding some weight gainers and more protein into my diet.

Some other benefits of mass gainers:
- You will stay hungry and keep eating
- You’ll get over 1000 extra calories
- Necessary vitamins are added
- Taste isn’t bad – unlike other supplements
- You will definitely get bigger
If this list looks like something you’re interested in, then keep on reading. We’ve developed this list to help those looking for the perfect weight gainer to build into their routine. Put on some weight with these awesome products.

If you don’t get very hungry or have an ultra-fast metabolism (like me), this will make all the difference. You can get by drinking one after workouts, or you can add more throughout the day for faster results. Be sure your body can handle the extra intake – I would recommend starting small and building up.
This blend comes in six different flavors, so just about anyone can find something that fits their tastebuds. In addition, you can save money if you buy a subscription to get repeated deliveries. You may want to be sure you like the taste and product before this though. Either way, you WILL get bigger with Optimum Nutrition.

Best Under $60 Weight Gainer for Skinny Guys
Naked Vegan Mass
What’s awesome about Naked Vegan Mass?
- 3 Ingredients – Wow
- GMO, Soy, and Gluten-Free
- Vegan
- 50 Grams of Protein
- 248 Grams of Carbohydrates
- 10.3 Grams of BCAAs
If Naked Mass was a little bit less expensive, it would have certainly topped our list! It’s one of the best weight gainers that exist, so that’s why it’s here on the best under $60 spot. You will really love this blend if you hate ingredients that are hard to pronounce or if you like things with minimal additives. Who wouldn’t like the idea of their shake being made of only Pea Protein Powder, Organic Rice Protein Powder, and Organic Maltodextrin (tapioca)? Naked Mass really is an awesome product!
If you’re a vegan, clean eater, or even lactose intolerant, then this blend is definitely right for you. You will gain weight and build mass – while avoiding some artificial sweeteners – here. As we said, you may not like the price tag in comparison to some of the other options, which really is why this didn’t take the number one spot. Naked has A LOT of happy customers and repeat buyers, so you know they’re doing something right!
With the happy customers always come some Debbie Downers, so we’ll fill you in. Some people were unhappy about 4 scoops being the serving size, so keep this in mind if considering Naked Mass. Also, there is a good bit of sugar (24 grams) per serving. I guess this is one of the prices to pay when staying vegan and avoiding artificial sweeteners. With the negatives come many more positives, so keep Naked Mass in mind if your need to put on some real and clean mass.

FAQ
How Can Skinny Guys Gain Weight?
Us skinny guys really do have a lot of trouble gaining weight. Some people envy us, but we all know it kinda sucks to have this problem if we want to get bigger. I could literally fit in clothes from when I was 11 years old when I was in my 20s. Since we tend to have a fast metabolism, much of gaining weight boils down to simply eating more.
If we take in more calories (I know sometimes it’s tough), we’re much more likely to put on the pounds. Protein powders, weight gainers, and other supplements can all help. If you aren’t a powder guy, then you’ll have to do some work – either cook more food with protein or eat a more balanced diet that will help you put on some mass.
You also want to continue lifting heavy and working out. We don’t just want to put on unnecessary fat – we want it to be muscle mass. So, you should definitely also have a good exercise routine. Some trainers will tell you to avoid cardio if you want to gain weight and you’re skinny, but I disagree. Cardio is good for overall health, so you don’t want to cut it out completely. Just be sure to eat more, eat better, and lift heavy.
How skinny people gain weight fast?
To be honest, it boils down to discipline – and what your definition of “fast” is. If you’re looking to put on some serious weight, then try to be patient. As I said above, it took me less than 6 months to put on 15 pounds, but I probably wasn’t working as hard as I could’ve been. Personally, I changed my breakfast routine, started eating protein with most meals, and drank a protein shake after my workouts.
Specifically, if you eat something like eggs and Greek yogurt for breakfast, start drinking shakes if you don’t already, and try to be mindful of what you’re taking in for every meal. In addition to this, you want to lift heavy and fairly often. With a good diet and workout routine, you can certainly put on some serious weight relatively quickly!
