Weight Gain Food List: 24 Best Healthy Foods For Gaining Weight Fast

Being underweight can be just as harmful as (or more than) being overweight. This can cause health issues such as infertility, a weak immune system, and osteoporosis. To prevent such issues, a doctor may recommend that you gain weight (28). This can simply be done by incorporating healthy, nutrient-rich foods into your diet.

Weight gain foods are typically high in calories and protein. While fatty, fried, and overly processed foods are also high in calories, they are not particularly the best for your health. In fact, they may even increase your risk for some chronic diseases (4).

That’s why it’s important to focus on healthy foods when you’re trying to gain weight. These 24 choices are all high in nutrients, low in unhealthy fats, and provide ample calories and protein to help you reach your goal weight.

• Milk

Whole milk is high in protein and calories, making it an ideal choice for weight gain (12). It also contains many essential nutrients, such as calcium, vitamin D, and potassium (13). 

• Yogurt

Like milk, yogurt is a high-protein food that is perfect for weight gain. It’s also packed with probiotics, which are important for gut health (6). 

• Eggs

Eggs are another high-quality source of protein. They also contain essential vitamins and minerals, such as choline, vitamin B12, iron, and zinc (25). 

• Nuts

Nuts are a great source of healthy fats, proteins, and fiber. They are also calorie-dense, making them an excellent food choice for weight gain (10). Be sure to include a variety of nuts in your diet to get the most benefit. Almonds, peanuts, cashews, and pistachios are all great options.

You can snack on these raw, add them to smoothies, or use them as a salad topping for extra crunch. 

• Beef

Beef is a high-quality source of protein and essential nutrients, such as zinc and iron (5). It’s also calorie-dense, making it an excellent choice for weight gain.

• Salmon And Oily Fish

Oily fish are the best sources of healthy omega-3 fatty acids (14). These fats are important for overall health and can help you gain weight in a healthy way.  

Some good options include salmon, mackerel, tuna, and sardines. These kinds of fish also contain high levels of protein and other essential nutrients such as vitamin D. 

You can either eat these fish steamed, sauteed, grilled or baked, or you can add them to your diet in the form of fish oil supplements, but in that case you will miss out on the protein that eating the fish can offer you.

Dried Fruit

Dried fruit is higher in sugar and calories than fresh fruit, making it an excellent food choice for weight gain (3). It also provides a variety of essential nutrients, including vitamin A, potassium, and iron. 

Some good options include apricots, raisins, figs, and dates. Be sure to avoid dried fruits with added sugar.

For people who are looking to gain weight, protein shakes can be a great way to do so. Protein shakes provide your body with the protein it needs to build muscle mass, and they can also be a source of additional calories (23) 

When choosing a protein shake for weight gain, it’s important to select one that is high in calories and has a good balance of protein and carbs. Some good options include:

• Hemp protein shake: Hemp protein is a good plant-based choice for those looking to gain weight because it is high in calories and protein, and it also contains healthy fats.
• Pea protein shake: Pea protein is another good plant-based choice for weight gain because it is high in protein and low in carbs. It also has a high glycemic index, which means that it will digest quickly and provide your body with energy.

When choosing a protein shake for weight gain, it’s important to make sure that you are getting enough nutrients. So be sure to choose a shake that is fortified with vitamins and minerals. And since you are not likely getting all the nutrients your body needs from your shake, be sure to also eat a healthy diet that is nutrient-dense.

Healthy Weight Gain Tips

Aside from a calorie-dense diet, here’s what else you can do to gain weight:

Eat Small Meals Every 3-5 Hours

When you eat small meals throughout the day, your body will have a constant flow of energy (26). This will help you to maintain a healthy weight and gain muscle mass. It also prevents you from feeling overly  full and sluggish. 

Include High-Calorie Snacks In Your Diet

If you find it difficult to eat enough calories in three meals, try snacking on high-calorie foods instead. Nuts, seeds, avocados, and dried fruit are all healthy snacks that are high in calories. 

Drink A Protein Shake After Working Out

A protein shake is a great way to refuel after a workout. Protein shakes are high in calories and help you to build muscle mass (22). They are also easy to digest, making them a good choice for people who have trouble eating after working out. 

Use Condiments And Toppings Often

Top your food with healthy condiments and toppings to add extra calories and nutrients. Nutritional yeast, avocado oil, olive oil, and grass-fed butter are all healthy additions to your diet. 

Nuts, dried fruit, cheeses, and salad dressings are also healthy toppings to consider. 

Get Plenty Of Sleep

Getting enough sleep is essential for overall health and well-being. It’s also important for weight gain (24). When you’re well-rested, you’re less likely to feel irritable or stressed. This will help you to make healthy food choices and maintain a healthy weight. 

Try Supplements

If you are having difficulty gaining weight, consider using supplements. Supplements such as protein powder, multivitamins, and omega-3 fatty acids can help you to reach your daily calorie goals. 

The Bottom Line

There are many healthy foods that can help you to gain weight quickly. By including such foods in your diet, you can reach your weight gain goals in a healthy and sustainable way.
