Most diets and health advice focus on weight loss rather than weight gain. As a result, finding reliable information on how to gain weight appropriately can be challenging. Whether you aim to increase body fat for health reasons or to prepare for a role in a new movie, you can achieve this in safe and healthy ways instead of avoiding exercise and consuming unhealthy foods. By following the right methods, you can gain weight while maintaining your health.
Steps
Preparing to Gain Fat

Consult a doctor. Before adjusting your diet or making any changes to your body, you should undergo a health check-up for a comprehensive evaluation. If you have a medical condition, such as high blood pressure or high cholesterol, your doctor may advise against gaining weight. Always take your doctor's advice seriously before making any changes.
- Certain medical conditions may require you to gain weight. Thyroid issues, digestive problems, diabetes, and cancer can lead to significant weight loss, posing serious health risks. Being underweight can result in health issues such as a weakened immune system, anemia, hair loss, and reduced bone density.
- Excessive physical activity can cause you to be underweight. If you're an athlete, gaining weight might benefit you by increasing your energy levels and allowing you to train for longer periods.

Set a goal. Having a clear plan is essential when aiming to gain weight. How much weight do you want to gain? Over what period of time? Answering these questions and creating a plan will help you achieve your weight gain goals more effectively.
- Start by determining how much weight you want to gain. You can set a personal goal or consult with a doctor and nutritionist. Either way, establish a specific target before beginning your weight gain journey.
- Remember that the basic principle of gaining weight is consuming more calories than you burn. When planning, calculate how much you need to eat daily to offset the calories burned. There are various tools available to estimate daily calorie expenditure, such as online calculators like http://www.caloriecount.com/tools/calories-burned
- You can also explore articles on setting realistic and achievable goals.

Start gradually. Suddenly consuming high-calorie foods in large quantities can be harmful to your heart, blood pressure, digestion, and other bodily systems. Gradually help your body adapt to increased calorie intake. Begin by adding 300 calories daily for about a week, then increase to 600 calories, and so on. This approach prevents your body from being overwhelmed as you start your weight gain regimen.
- Break your weight gain journey into phases. Determine how much weight you want to gain each week or month. This allows your body to adjust slowly rather than gaining too quickly.
- Similar to weight loss, aim for gradual weight gain. Gaining 0.25-0.5 kg per week is healthy (achieved by adding 250-500 calories daily). Avoid exceeding 500 extra calories per day.

Plan your meals. To gain weight, you need to eat more. Focus on nutrient-dense, calorie-rich foods rather than unhealthy options. Many foods can help you gain weight while providing all the nutrients your body needs to stay healthy.
- Increase your meals to more than three per day. Aim for over five meals daily, including snacks throughout the day.
- Ensure your meals are nutritionally balanced. Each meal should include carbohydrates, protein, and unsaturated fats—the three most beneficial nutrients for weight gain.
- Eating more frequently and incorporating healthy foods into your diet can be costly. Therefore, plan a new budget to accommodate your dietary changes.

Incorporate strength training. In addition to gaining fat, building muscle can also contribute to weight gain. Strength training helps utilize the nutrients you consume to build muscle. Increasing muscle mass ensures you maintain strength and overall health while gaining fat.
Eat the right types of food

Consume foods rich in unsaturated fats. While fats are essential for gaining weight, not all fats are created equal. Saturated and trans fats may help you gain weight but can also increase cholesterol levels and the risk of cardiovascular diseases. On the other hand, unsaturated fats reduce the risk of heart disease and boost the immune system. Ensure each meal includes a source of unsaturated fats.
- When aiming to gain weight, focus on these "good fats" to increase body fat healthily while providing essential nutrients your body needs.
- Nuts, peanut butter, fatty fish like salmon and mackerel, and avocados are rich in unsaturated fats and calories, offering essential nutrients. Incorporate these foods into your main meals or snacks throughout the day.

Eat whole grains or whole wheat carbohydrates. Carbohydrates act as the body's energy source. If you don't burn this energy, it gets stored as fat, aiding weight gain. After fats, carbohydrates are the next most important factor in weight gain, so increase your intake of carbs in your diet.
- Focus on consuming whole grains instead of refined carbohydrates. Refined grains are bleached and processed, losing most of their essential nutrients. Whole grains, however, provide carbohydrates along with fiber, vitamins, and minerals.
- Replace refined grains with whole-grain bread, pasta, and brown rice. Increase carbohydrate intake to support weight gain.

Use full-fat dairy products. Dairy is an important part of the diet due to its calcium and vitamin content. Most dairy products are low-fat, so opt for full-fat versions to increase calorie and fat intake. Drink whole milk and consume cheese and yogurt made from whole milk.
- Replace sugary drinks (which lack vitamins and nutritional value) with a glass of whole milk to increase fat intake and nourish your body.
- Note that whole milk contains high levels of saturated fat. However, some evidence suggests that full-fat dairy products may help reduce the risk of cardiovascular disease.

Incorporate meat into your diet wisely. Protein and fats from meat are essential for weight gain. However, be cautious with red meat consumption. Studies conclude that excessive red meat intake can lead to cardiovascular diseases and certain cancers. Limit red meat to 3-5 servings per week to maintain health. Otherwise, opt for poultry to provide protein and unsaturated fats.

Add calorie-dense ingredients to your meals. You can eat your usual meals but enhance them with ingredients that promote weight gain. Some healthy and effective options include:
- Adding boiled eggs to salads.
- Incorporating cheese into sandwiches, eggs, and salads.
- Using sauces and gravies with meat dishes.
Tips for Gaining Fat

Avoid consuming refined and processed sugars. Gaining fat doesn't mean you have to eat unhealthy foods all day. Instead, focus on calorie-dense, nutrient-rich foods that provide vitamins and essential nutrients. Processed sugars offer no nutritional value and can lead to diabetes, cardiovascular diseases, tooth decay, hormonal issues, and other health problems.
- Cut down on sugary foods as much as possible. Candies, cakes, cookies, and other desserts are typically high in sugar.
- Reduce or avoid sugary drinks. A single can of soda contains more sugar than most desserts.

Eat before sleeping. When you sleep, your body requires fewer calories. The food you consume before bed is more likely to be stored as fat. Take advantage of this by eating a larger meal before bedtime, combined with strength training or going to bed right after lunch.

Avoid drinking water 30 minutes before meals. Water fills your stomach and can make you feel full prematurely. To prevent this, avoid drinking water about 30 minutes before eating. This ensures your stomach is empty, allowing you to finish your meal.

Exercise correctly. Gaining weight doesn't mean you should stop exercising. In fact, becoming inactive and stopping exercise can be detrimental to your health.
- Improper weightlifting can hinder your weight gain goals. Strength training boosts metabolism and burns more calories. Therefore, after workouts, replenish calories to prevent excessive calorie burning and continue gaining weight.
- Stretch regularly. Inactivity can cause muscle stiffness and reduce flexibility. Stretch your arms, legs, hips, and back daily to keep your body flexible and functioning well.

Use protein shakes to gain weight. In addition to eating more, you can increase your body weight with protein shakes and protein powder. Many products provide protein to help you gain weight and build muscle when combined with strength training. Always follow the product instructions carefully.
- Whey protein powder is a popular option that can be added to various beverages. Blend it with fruits, yogurt, and a few scoops of protein powder for a nutritious shake.
- There are numerous protein drinks and bars available. Use them as snacks throughout the day to boost your calorie intake.
- Read product labels carefully when purchasing. Many products contain added sugars that can harm your health. Opt for products with minimal added sugars.
Warnings
- Continue regular health check-ups. Gaining fat is a significant change for your body, so regular doctor visits are essential to ensure healthy weight gain.
- Gaining fat is only beneficial for those who are underweight.
- You cannot target fat gain to a specific area of your body. Weight gain will be distributed evenly. If you aim to increase the size of your chest, hips, or buttocks, understand that your overall body size will also increase.
