Hey there! Are you a skinny guy looking to build muscle? Have you heard about intermittent fasting for skinny guys and how it can help you achieve your fitness goals? Well, you’ve come to the right place, my friend! Let’s start with the basics. Intermittent fasting is a dietary approach where a person cycles between periods of eating and fasting.

During the fasting period, the individual abstains from consuming any food or calorie-containing beverages. While during the eating period, they consume their normal meals. It has become more popular, especially in the fitness community, as a way to boost overall health and potentially aid in weight loss. But don’t worry, it’s not as scary as it sounds!

Now, there are a few misconceptions out there about fasting and its benefits. Some people think fasting means starving yourself, but that couldn’t be further from the truth. Intermittent fasting involves timing your meals strategically to maximize the benefits of fasting, like:

  • Improving insulin sensitivity.
  • Reducing the risk of type 2 diabetes.
  • Promoting weight loss.
  • Increasing longevity.
  • Enhancing brain function.
  • Reducing inflammation.
  • Boosting autophagy.

So, if you’re a skinny guy looking to build muscle and improve your overall health, then intermittent fasting might be a great strategy for you! In this article, we’ll delve deeper into the science behind fasting, how it can help you gain muscle, and provide tips for starting an intermittent fasting routine. Get ready to transform your body from skinny to muscular and improve your health with the power of intermittent fasting!

The Science Behind Intermittent Fasting

     When it comes to intermittent fasting, it’s not just about skipping meals. There’s actual science behind it that can help you achieve your health and fitness goals. Let me explain.

Intermittent fasting can help reset your body’s metabolism. When you fast, your body enters a state called ketosis, which means it starts burning fat for fuel instead of glucose. This is great for weight loss, but it also might help with muscle growth.

But that’s not all – fasting can also improve your insulin sensitivity. This helps the body use the nutrients consumed during the feeding window to build muscle more effectively. Fasting also promotes autophagy, which removes damaged cells that can hinder muscle growth and promotes the growth of new, healthy cells.

And let’s not forget about growth hormone – the key to muscle growth and repair. By fasting, you can naturally boost your body’s production of this hormone (1), leading to bigger gains.

Bottom Line

Intermittent fasting can help reset your metabolism, promote fat-burning and muscle growth, improve insulin sensitivity, and stimulate growth hormone production. It is a powerful tool to help you achieve your health and fitness goals.

Intermittent Fasting for Skinny Guys

     Intermittent fasting can be a great way for skinny guys to gain muscle mass and improve their overall health. However, you can’t just fast and hope for the best, it’s important to make sure you’re still getting enough calories during your feeding window to support muscle growth. So, how do you do that?

That means you need to be mindful of what you’re eating and make sure to consume enough protein, carbs, and healthy fats. Don’t worry, there are some awesome apps out there that can help you track your calorie and nutrition intake, like Cronometer or Macrofactor.

     When choosing muscle building foods during your feeding window, focus on nutrient-dense options. Lean protein sources like chicken, fish, and turkey, as well as healthy fats like avocados and nuts, are great choices. Complex carbohydrates like sweet potatoes and quinoa provide energy for workouts and muscle recovery. So go ahead, load up on those delicious, muscle-building foods, and watch your gains soar!

Bottom Line

To gain muscle successfully with intermittent fasting, you must consume enough calories during your feeding window. This can be achieved by selecting nutrient-dense foods and using tracking apps to monitor your calorie intake.

How to Get Started With Intermittent Fasting?

     Starting an intermittent fasting routine can be a bit challenging, but don’t worry, we’ve got your back! Here are a few tips to help make the transition easier.

Firstly, try gradually increasing the length of your fasting window. Start with a 12-hour fast and work your way up to a 16-hour fast over a few weeks. This way, your body can adjust to the new eating schedule without feeling deprived. And don’t forget to stay hydrated during your fasting period. Drink water, unsweetened tea, or black coffee to keep yourself from feeling hungry.

     Now, when starting an intermittent fasting routine, there are a few common mistakes to avoid. One of them is overcompensating by eating too much during the eating window. Instead, make sure to consume enough calories to support muscle synthesis, but be mindful of not overdoing it.

Another mistake to avoid is breaking your fast with unhealthy foods like processed snacks or sugary treats. It may be tempting to reach for these foods when you’re hungry, but they won’t provide the nutrients your body needs to function properly and support muscle growth. Choose whole, nutrient-dense foods like lean proteins, fruits, and veggies to nourish your body and give you the energy you need for your workouts.

Bottom Line

To start an intermittent fasting routine, gradually increase the fasting window and stay hydrated. Avoid overcompensating with calorie intake and breaking the fast with unhealthy foods, opting instead for whole, nutrient-dense options. 

Intermittent Fasting and Exercise

    If you’re planning to include exercise in your intermittent fasting routine, there are a few things you should know.

First and foremost, listen to your body. It’s essential to take it easy and not push yourself too hard when you feel exhausted or low on energy during your fasting period. No pain, no gain is not the way to go when you’re fasting. It’s better to go slow and steady, and you’ll get there eventually.

Secondly, schedule your workouts during your eating window when your body has the energy and nutrients to fuel them and support muscle growth. You don’t want to feel like you’re running on empty when you’re lifting weights or doing squats.

Now, let’s talk about the best types of workouts to do. Resistance training or weightlifting is an excellent option for skinny guys looking to build muscle mass. Exercises like squats, deadlifts, bench presses, pull-ups, and overhead press are effective for muscle growth. While other exercises like running or cycling are good for overall fitness, they may not be as effective for muscle growth.

Remember, the key is to find a workout routine that works for you and that you enjoy doing. Don’t force yourself to do exercises you don’t like, or you’ll just end up quitting. By combining intermittent fasting with regular exercise, you can build muscle and improve your overall health and well-being.

Bottom Line

Bottom line: Exercise is an excellent addition to your intermittent fasting routine, but it’s essential to listen to your body, schedule your workouts during your eating window, and focus on resistance training to promote muscle growth.


     Great job! You’ve made it to the end of this guide. As a quick summary, intermittent fasting can promote muscle growth, improve insulin sensitivity, and stimulate growth hormone production. To make the most of intermittent fasting, it’s important to focus on nutrient-dense foods and gradually increase the fasting window.

Remember to stay hydrated, avoid overcompensating with calorie intake, and avoid unhealthy processed foods when breaking your fast. With dedication and consistency, you can achieve your fitness goals and transform your body from skinny to muscular. So, what are you waiting for?
