Ready-to-eat foods alone can't make you gain weight. However, healthy fats, protein, milk, avocado, nuts, or salmon can help increase your body weight.

Milk for Strong Bones and Energy

Milk contains protein, carbohydrates, healthy fats, calcium, vitamins, and whey proteins. According to research, drinking milk after exercising helps build muscle. It is more beneficial than soy milk in this regard.

Drinking a cup of milk every night before bed helps you sleep well at night and also helps increase your body weight.

Avocado

Although avocado doesn't contain a huge number of calories, eating it regularly helps promote weight gain. One avocado contains 332 calories, 29 grams of fat, and 17 grams of fiber. It also contains vitamins C, E, and K, and can be eaten with salads and sandwiches.

Red Meat

Red meat helps increase body weight and strengthens muscle building.

Since it contains protein and fat that are beneficial for muscle building, it helps increase body weight.

However, eating it in excess can be harmful to your health.

Tofu

Tofu is a food made from soy milk through a production process. It is a good substitute for meat for vegetarians. The protein, leucine, and calcium it contains are beneficial for muscle building.
