18 Best Healthy Foods to Gain Weight Quickly and Safely

Introduction
People think gaining weight is easy; you just have to eat more, right? And for a lot of them, it often is easier than losing weight, but that’s not the case for everyone, especially for people with a fast metabolism, medical conditions, or those who are underweight.
This article will explore the best weight gain foods, how to maintain a safe calorie surplus, and gain healthy weight without compromising your health.
Why Do Some People Have Trouble Gaining Weight?
People think gaining weight is much easier than losing weight, but that’s not how it works. Many people, for different reasons, have trouble gaining weight, and here are a few reasons why:
- Fast Metabolism. Some people can burn calories faster than they can consume them.
- Poor appetite or stress.
- Medical conditions, such as hyperthyroidism, malabsorption, and others that impact appetite and weight.
- Genetics.
If one of these scenarios applies to you, then you need foods that are nutrient-rich and also calorie-dense to gain weight safely, without engaging in binge eating practices.
How to Gain Weight in a Healthy Way
Gaining weight quickly doesn't mean eating junk food or binge eating! Instead, you should:
- Eat more calories than you use to create a calorie surplus.
- Include protein-rich foods in your diet for muscle-building
- Add healthy fats and complex carbs to your diet with the protein.
- Eat regularly and have at least five to six meals per day.
- Use weight gain foods and natural dietary supplements as needed, but don’t forget to consult with your doctor before you make any drastic changes to your diet.

What Makes a Food the Best Option for Weight Gain?
The best weight gain foods are:
- High in calories
