We understand that it is very hard to gain weight for some people. Your weight might result from your genetics. It can be explained by fast metabolism or can be due to the small amount of food you eat. Whatever the reasons are, you can challenge them. It’s not going to be an overnight change. Achieving your goal weight might take you some time. However, by eating in a surplus and working out, you will get there. Just stay consistent in your endeavors.

What is metabolism, and how does it affect your weight?

Metabolism is a sum of chemical reactions in your body. It determines how food transforms into energy and how your body uses it for living. It includes your physical activity, non-exercise thermogenesis, energy spent to digest food, and basal metabolic rate (the energy your body uses to fuel the brain, muscle tissue, and other organs).

If you have a fast metabolism, your body needs a lot of energy to live. In other words, you need more food to maintain your weight. If the quantity of calories you should be eating is more extensive than you actually eat, you can discover trouble gaining weight.

Is it okay to be underweight?

Being underweight is not always a choice. There are health conditions that can lead to extreme weight or appetite loss. If you start to lose weight without any effort on your behalf, you should immediately see your doctor. It might be caused by diabetes, infections, cancer, or thyroid misfunction.

Health providers determine whether someone's underweight or not by the body mass index. If a person's BMI is below 18.5, they will be considered underweight. If you feel good, have no health issues, and love the way you look with a BMI lower than 18.5, there is no need to worry. Body mass index is just a number. It doesn't consider your genetics, age, and other important factors.

However, underweight people might have greater risks of bone fractures due to the lower bone mineral density. They might have lower fertility and even greater chances of developing dementia.

The main reason behind being underweight is eating fewer calories than you burn. There are two parts to this equation. 

On the one side, your metabolism might be too fast. It happens when you lead an active lifestyle or work physically. Your body can also spend a lot of energy on functioning. If you live in a cold climate and don't dress very warm, your body needs more energy. 

On the other side, you might be in a calorie deficit. This means you don't get enough energy from food and cannot get to the anabolic state when your body builds new muscles or fat tissue.

How does gaining weight for men and women differ?

Men usually have more insecurities about being too skinny because of beauty standards. 

As men have more muscle mass than women, their metabolism is faster too. It can be more challenging for men to gain muscle because they need to consume a lot more calories. The thing is, you need more energy to maintain your muscles than fat. You need to increase your calorie intake when you become bigger.

New lifters can gain one to four pounds of muscle a month. So, the process of transformation is neither easy nor fast. And because of the changes between men and women, it is even harder to build muscle as a female.

As women on average have a bit slower metabolism than men, gaining weight might be easier for them. On the other hand, getting new pounds from muscle and not fat tissue will be more challenging for women.

Both males and females can grow muscles with regular exercise. However, men tend to have more upper body gains and women easies obtain muscle tissue in the lower body.

10 ways to gain weight quickly and healthily

Eating more calories than you burn is the only way to gain weight. See what you can do to make the first part of the equation easier.

1. Don't skip meals 

Many busy people have this habit. Have at least three square meals a day or add more calorie-dense snacks.

2. Count calories 

You will know for sure how many calories you need to gain weight. After a couple of weeks, you will know how much food to eat even without counting. 

3. Prepare meals in advance 

If your days are too busy, prepare several servings at a time. Bring leftover meals to your office instead of buying snacks and coffee.  

4. Drink your calories

Add creamer to your coffee, have the whole and not skim milk, and drink juices and smoothies. They all contain calories but don't make you feel stuffed or bloated.

5. Don't spend too much time at the gym 

You will get decent results if you exercise from 20 to 90 minutes 2-3 times a week. Anything above that volume won’t bring significant changes to your progress

6. Focus on strength training 

Pilates, running, or yoga are great for your health. However, you should choose strength-oriented types of sports to gain muscles.

7. Try post-workout shakes

These are weight gainers that contain proteins and carbs. You can prepare protein shakes yourself or buy mass gainers at sports nutrition stores.

8. Choose whole-fat foods

If you were buying fat-free products just out of habit, stop it right now. Eat whole eggs and not egg whites from a bottle, buy 50% fat cheese instead of low-fat versions, cook an entire chicken and not chicken breasts, etc.

9. Add more oil to your salad

When increasing your fat consumption, remember that there are fat sources that are beneficial for your health (like olive oil, fish, and nuts) and not that healthy trans fat and saturated fats.

10. Try creatine

There are a few supplements for muscle growth that are safe for your health and show science-based efficiency. Creatine is one of them. It can help you improve your strength and power and assist with muscle growth and recovery.

If you're a healthy person with no critical health conditions, you will quickly gain weight using these tips. However, if you want the biggest part of your weight gain to come from muscles and not fat tissue, you will have to add workouts with progressive overload to your routine.

Tips to help you gain weight 

  • Decrease the amount of cardio you do. 
  • If you're prone to fidgeting and moving your body, try to stay calm and rest most of the day.
  • Choose low reps with high weights. Do three to four sets with a maximum of eight reps of each exercise to maximize muscle hypertrophy. 
  • Do compound movements instead of isolated exercises.
  • Stay consistent with your workout plan. There are multiple online programs, and you can choose whatever fits you, from push-pull-leg slits three times a week to more coherent 5-day split workouts. 
  • Lifting weights can increase your appetite too. So, if you're struggling to eat extra calories, you should definitely try heavy lifting!
  • Track your progress. Keep a diary of your nutrition, weight gains, and workouts.

How much time you need to gain weight

Muscle gaining process depends on various factors that include your age, exercise experience, nutrition, the type of sports you do, sleeping hours, and stress levels. You cannot affect your age and sports background but make sure you eat and rest well as muscles grow during the resting phase. 

You will start seeing a difference in your scales in a couple of weeks of regular exercise. Wait for the first noticeable gains that will make you change your clothing size in 3 months. You will be able to obtain more muscle mass in the first year of strength training

Good foods for gaining weight with a fast metabolism

  • Complex carbohydrates. Such foods are rice, quinoa, oatmeal, and whole-wheat bread should be the base of your diet. 
  • Nuts and nut butter. They are very dense in calories and taste good. So, you can quickly eat a lot of additional calories with no effort.
  • Starchy vegetables. Corn, beans, potatoes and sweet potatoes, beans are all a perfect fit for your nutrition. They contain vegetable protein in addition to carbs. 
  • Red meat. It contains more fats than poultry and helps you reach your calorie goals easier. 
  • Fatty fish. Apart from being a good protein source, such fish as salmon is rich in Omega-3 fatty acids and calcium.
  • Whole milk products. They contain more calories and are better for muscle mass development than skimmed dairy.
  • Protein shakes and bars. These snacks are rather calorie-dense but contain enough fats and proteins if you compare them with regular sweets. 
  • Fast food. You might be surprised, but it works well if you choose the right options. One Quarter Pounder with Cheese contains 30g of protein.

Summing up 

You can gain weight only if you are in a calorie surplus. To create a calorie surplus you need to move less or eat more. 

Gaining muscles is the healthiest way to put on weight. Make sure you eat enough qualitative food and exercise regularly to see progress. Don’t forget that resting after a workout is as important. 

High-calorie-dense foods and sports supplements can help you obtain muscle faster and easier.
