Gaining weight with intermittent fasting

If you're reading this article, you're probably interested in gaining weight while practicing intermittent fasting. You're in the right place! I've also experienced the amazing world of intermittent fasting benefits, but my main goal was always to gain weight and build muscle. However, when researching online, I realized that information on how to gain weight while fasting is scarce. For this reason, I've decided to create this article where I'll address, with scientific information, the key aspects for those who want to increase their body weight while still enjoying the benefits of intermittent fasting. If you resonate with this quest, I invite you to read the complete article and explore this fascinating topic together. Let's begin.

Is it Possible to Gain Weight While Fasting?

First and foremost, let's address the fundamental question: is it possible to gain weight while fasting? The answer is a resounding yes. In fact, with intermittent fasting, you can burn fat and build muscle simultaneously (Journal of Translational Medicine, 2016).

To achieve this, it's crucial to increase your calorie intake during the eating window, ensuring that you provide your body with essential nutrients for muscle growth, such as proteins. During fasting, your body can mobilize stored fat reserves for energy.

Several experts, including Dr. La Rosa, recommend a 16-hour fasting regimen followed by an 8-hour eating window. Combined with a high-protein diet and strength exercises, this can promote muscle mass gain.

Benefits of Weight Gain with Intermittent Fasting

The reason behind this possibility lies in the increased levels of growth hormones and testosterone produced during fasting. This partially compensates for potential muscle loss and helps in muscle recovery and growth when you consume sufficient nutrients during your eating window.

Aside from muscle growth, there are other benefits of gaining weight through intermittent fasting:

  • Better insulin sensitivity and blood sugar control.
  • Enhanced metabolism.
  • Improved cardiovascular health.
  • Reduced inflammation.

How to Gain Weight Effectively with Intermittent Fasting

Now that you know gaining weight with intermittent fasting is feasible, let's explore the steps to do it effectively:

  1. Calculate Your Caloric Needs: Determine your daily caloric needs, including your basal metabolic rate (BMR) and activity level. This will help you set an appropriate calorie goal for weight gain.
  2. Choose the Right Eating Window: Opt for an eating window that aligns with your daily schedule and allows you to consume the necessary calories and nutrients comfortably.
  3. Eat Nutrient-Dense Foods: Focus on whole, nutrient-dense foods like lean proteins, fruits, vegetables, whole grains, and healthy fats.
  4. Incorporate Protein: Protein is crucial for muscle growth. Aim for an adequate protein intake to support your workouts and recovery.
  5. Stay Hydrated: Drink enough water to stay hydrated, as it's essential for overall health and metabolism.
  6. Strength Training: Include strength training exercises in your routine to promote muscle growth and strength.
  7. Monitor Your Progress: Keep track of your weight gain progress and make adjustments to your diet and workout routine as needed.

Sample Intermittent Fasting Weight Gain Meal Plan

Here's a sample meal plan to help you get started:

Breakfast (12 PM): Scrambled eggs with spinach and whole-grain toast.

Potential Challenges

While gaining weight with intermittent fasting is possible, it may come with some challenges:

  • Appetite: You may need to adjust to eating larger meals during your eating window if you have a small appetite.
  • Consistency: Sticking to your eating and fasting schedule consistently can be challenging.
  • Meal Planning: Planning nutrient-dense meals that meet your calorie goals requires effort.

Overcoming these challenges with patience and determination will be essential for successful weight gain.


Gaining weight while practicing intermittent fasting is achievable and offers numerous health benefits, including improved muscle growth and overall well-being. By following a well-planned eating and workout routine, you can reach your weight gain goals while reaping the rewards of intermittent fasting. Remember to consult with a healthcare professional or nutritionist before making significant changes to your diet or fasting regimen to ensure it aligns with your individual needs.
