Evidence based Intermittent Fasting for Muscle Gain & How It Can Help You Reach Your Fitness Goals
Introduction: How Does Intermittent Fasting Help With Muscle Gain?
Improved muscle building and fat loss can be achieved with intermittent fasting. According to studies, it can decrease inflammation, raise testosterone levels, stimulate the generation of growth hormones, and aid in muscle rehabilitation. It also helps regulate insulin levels, which helps with the optimal use of nutrients and prevents the storage of excess energy as fat.
Intermittent fasting can also maximize the time and energy devoted to building muscle. Fasting before a workout helps increase focus, giving you more strength and allowing you to train harder for longer. The fasted state can also enhance fat burning, which helps improve body composition by reducing overall body fat percentage.
Is intermittent fasting good for muscle gain? It’s a great way to improve muscle gain, but it should be done with a balanced diet and exercise regimen. Eating nutrient-dense meals during eating windows and getting adequate rest and recovery essentials are essential. With the correct structure, intermittent fasting can be an effective tool for achieving fitness goals!

Understanding the Science Behind Intermittent Fasting Muscle Gain
Let’s dive into the science behind intermittent fasting and muscle gain in a friendly and easy-to-understand way.
Intermittent fasting is a dietary approach that involves cycling between periods of eating and obtaining from eating, also known as fasting. Intermittent fasting supports muscle gain while improving overall health.
While the primary focus of intermittent fasting is often weight loss, it can still be compatible with muscle gain when done correctly.
During fasting periods, your body taps into its energy reserves, including stored fat, to meet its energy needs. When you are fasting, you are only limiting eating to certain periods of the day. This eliminates the temptation to snack. This can lead to a calorie deficit vital for weight loss. However, ensuring you’re still consuming enough calories and nutrients during your eating window to support muscle growth is crucial.
To promote muscle gain while intermittent fasting, you should consider two key factors: calorie intake and protein consumption.
- Calorie Intake
Even if your primary goal is to lose weight by fasting and building muscle, it’s still imperative that you eat enough calories to support muscle growth. A lack of calories can prevent muscles from growing due to the body trying to conserve energy. For adequate energy for muscle growth and repair, consume lean proteins, whole grains, fruits, and vegetables appropriate for your age and weight.
- Protein Consumption
Protein is a vital macronutrient for muscle building. It provides the necessary amino acids that support muscle repair and synthesis. When intermittent fasting, distribute your protein intake evenly throughout your eating window.
Aim for about 0.7 to 1 gram of protein per pound of body weight daily. Lean meats, chicken, fish, eggs, dairy products, legumes, and plant-based choices like tofu and tempeh are all excellent sources of protein.
Additionally, it’s crucial to engage in regular resistance training exercises. Intermittent fasting alone may not stimulate muscle growth to its fullest potential. Resistance exercises, such as weightlifting or bodyweight workouts tailored to the appropriate resistance and difficulty levels, help stimulate muscle protein synthesis and promote muscle hypertrophy (growth).
Can You Build Muscle While Intermittent Fasting?
In a world where quick fixes and weight-loss fads are abundant, intermittent fasting has shown its staying power. Even those involved in strength training are curious about intermittent fasting and its potential impact on muscle building. So, let’s explore whether intermittent fasting can help build muscle.
While most studies on intermittent fasting have primarily focused on its effects on weight loss, it can be an effective tool for breaking through plateaus in strength training. However, the available research regarding combining intermittent fasting with regular resistance training is not fully comprehensive and somewhat anecdotal.
However, the results suggest that individuals following intermittent fasting may experience similar muscle gains and maintenance compared to those following a regular diet, even if they may lose more weight.
It’s important to note: most studies on intermittent fasting have focused on its effects on weight loss. When it comes to losing weight, whether through intermittent fasting or other diets, it’s common to lose both fat and lean mass, including muscle. It will be important to fully study the effects of strength training and intermittent fasting for future research.
Other studies suggest that lean mass may be slightly lost after several months of intermittent fasting, typically around 1 kg or 2 pounds. However, intermittent fasting might be more effective at preserving lean mass during weight loss than non-fasting diets. This means that you are likely to lose more fatty tissue than muscular mass when fasting.
Overall, intermittent fasting is unlikely to cause more muscle loss than other weight loss diets. Generally, when you lose weight, losing fat and lean mass is somewhat expected if you’re not exercising regularly. So, intermittent fasting doesn’t have a detrimental effect on muscle compared to other weight loss approaches.

Does Fasting Burn Fat or Muscle – Simply Explained
When you fast, your body needs to find energy from somewhere since you’re not consuming food. Initially, your body uses the glucose stored in your liver and muscles. Once the glucose stores are depleted, fat becomes its primary fuel source.
By enabling your body to use stored fat for energy, fasting helps you burn fat efficiently. During this process,it encourages fat oxidation, which is the process through which your body converts fat into energy. This may result in a reduction in body fat percentage and weight loss.
However, there is a concern that fasting may also cause muscle loss. When your body is in an energy deficit, it can break down muscle tissue to provide amino acids for energy. This brings us back to the importance of proper calorie and protein consumption during intermittent fasting. This muscle breakdown can happen if you don’t eat enough protein or have an extremely low-calorie intake.
To minimize muscle loss during fasting, it’s essential to do the following steps:
Eat adequate protein
Consuming enough protein during your eating periods is crucial. The building blocks for muscle growth and repair are provided by protein. On a daily basis, aim for 0.7 to 1 grams of protein per pound of body weight and split it up between your meals for the day.
Maintain a balanced diet
Ensure you get various nutrients from whole foods during your eating periods. Include lean proteins, fruits, vegetables, whole grains, and healthy fats to support overall health and muscle preservation.
Engage in resistance training
Regular strength training exercises can help preserve and build muscle. In addition, resistance training stimulates muscle protein synthesis, which is vital for muscle growth and maintenance and supports bone health.
Keep in mind that everyone’s body is different, and it’s always a good idea to consult with a healthcare professional or registered dietitian before making significant changes to your diet or exercise routine especially if you are dealing with any diseases or injuries.
Is Fasting Good for Muscle Growth – 5 Proven Reasons
Fasting is an effective way to stimulate muscle growth. This is due to several factors, including improved hormone regulation and the body entering a catabolic state of fasting. Here are five proven reasons why fasting can be beneficial for muscle growth:
Increased Growth Hormone Production
Fasting increases the production of human growth hormone (HGH) hormones. Increased levels of HGH lead to increased lean muscle mass and lower body fat percentage.
Improved Insulin Sensitivity
Fasting helps improve insulin sensitivity, so your body will respond better to post-workout nutrition. This helps with muscle recovery and performance, leading to quicker gains in size and strength.
Increased Autophagy
Fasting stimulates autophagy, recycling old and damaged proteins into new ones. This helps repair old cells and muscle tissue, allowing them to rebuild stronger.
Catabolic State Fasting
When you fast, your body enters a catabolic state, breaking down fat stores and amino acids to create energy. This releases essential nutrients like branched-chain amino acids (BCAAs), which are vital for muscle growth. During intermittent fasting, your body cycles through stages of catabolism (breakdown) and anabolism (building).

Does Fasting Burn Muscle or What Are the Risks??
The consequences of fasting can vary depending on the individual, so it is vital to be aware of possible risks before starting a fast. Generally speaking, fasting does not burn muscle if done correctly and in moderation. However, some studies suggest intermittent fasting can cause muscle loss, particularly in bodybuilders.
In one study, researchers found that intermittent fasting caused more muscle loss than continuous energy restriction in bodybuilders who had been training for at least two years. This suggests that athletes should consider their calorie intake when considering an extended fast as part of their diet plan to minimize the potential risks of losing muscle mass.
It’s also important to note that even healthy individuals may experience health risks associated with fasting, such as dehydration and electrolyte imbalances. Therefore, if you are considering a fast, you should consult your doctor before starting to ensure it is safe.
Although fasting may not cause a decrease in muscle mass if done correctly and in moderation, it is still essential to be aware of the risks associated with extended or intermittent fasting. Therefore, it’s recommended that athletes consider their total calorie intake when considering an extended fast as part of their diet plan and that all individuals consult their doctors before beginning any fast.
Ultimately, fasting can produce positive and negative results for individuals depending on how it is approached. However, with careful planning and considering potential risks, fasting can be a safe and beneficial part of any diet and fitness plan.
Gaining Weight on 16:8 Intermittent Fasting – Why It Can Happen
It can be disheartening to start a new diet or nutritional plan and find that you’re actually gaining weight instead of losing it. However, if you’ve been using the 16:8 intermittent fasting method and are wondering why you’re not seeing results, there are several potential reasons.
First and foremost, check for any miscalculations in your macros — meaning how many grams of fat, carbs, and proteins you consume daily. If your macro numbers don’t add up correctly, this could spell trouble when working towards your goal weight.
Another possible reason for weight gain with intermittent fasting is due to overconsuming calories during the 8-hour eating window. People often think that if they are fasting for 16 hours that they can eat whatever they want for the remaining 8, but this simply isn’t the case. The eating window should still include healthy and balanced meals with the proper macronutrient ratios.
Does Fasting Build Muscle and 6 Amazing Hacks
Let’s address the question of whether fasting can build muscle, along with six amazing hacks to support muscle growth:
- Caloric Surplus
You generally need to consume more calories than you burn to build muscle. However, fasting alone may make achieving a consistent caloric surplus challenging. Therefore, it’s essential to prioritize consuming enough calories during your eating periods to provide your body with the energy it needs for muscle growth.
- Timing of Protein Intake
Distribute your protein intake evenly throughout your eating periods. Spacing out protein-rich meals can help optimize muscle protein synthesis and support muscle growth and repair.
- Resistance Training
Engage in regular resistance training exercises to stimulate muscle growth. Include activities that target major muscle groups and progressively increase the intensity and resistance over time. This could include weightlifting, bodyweight exercises, or resistance bands.
- Sufficient Protein Intake
Research has found that consuming enough protein is essential for muscle growth and development. Eating enough protein regularly throughout the day will ensure you meet your fitness goals which may include getting abs! In addition, it can be an effective way to help build lean muscles.
- Nutrient-Dense Meals
Focus on consuming nutrient-dense foods during your eating periods. Instead, opt for whole grains, fruits, vegetables, and healthy fats to provide essential vitamins, minerals, and antioxidants that support overall health and muscle function.
- Hydration and Rest
Stay hydrated throughout the day, as water is essential for optimal muscle function. Especially hydrate after a difficult workout. Also, prioritize sufficient sleep and rest to allow your muscles to recover and grow. Aim for 7-9 hours of quality sleep each night.
Fasting and Weightlifting: How to Get Started
When it comes to fasting and weightlifting, timing is crucial. After a workout, you may be tempted to eat right away, but this can impede recovery. Instead, wait at least an hour before eating to allow your body time to replenish its glycogen stores and repair any muscle tissue damage caused by the workout. During this period, you should focus on staying hydrated with plenty of water and electrolytes.
Fasting immediately after a workout can help maximize fat loss while retaining as much muscle mass as possible — especially when combined with calorie restriction. Studies have shown that fasting at least 12-14 hours after exercise can increase fat oxidation (the rate at which your body uses fat for energy). However, it’s important to note that you should always eat enough food to meet your daily caloric needs.
If you’re interested in combining fasting with weightlifting, try these strategies:
- First, select a fasting method that aligns with your lifestyle and preferences.
- Determine the timing of your eating window to align with your workout schedule.
- Experiment with different eating windows to find what works best for you.
- Make sure to consume enough vitamins and protein.
- Before your workout, have a small meal or snack with carbohydrates and protein.
Intermittent Fasting and Bulking: Best Practices to Follow For Maximum Results
Intermittent fasting and bulking are great ways to get the most out of your bodybuilding efforts. However, there are some best practices you should follow for maximum results.
One challenge with intermittent fasting (IF) is that it can take time to meet your daily macronutrient needs. In addition, if you struggle to consume enough calories to gain weight restricting your eating window can make it even more challenging.
Methods like alternate-day or 48-hour fasting may not be suitable for hard gainers. In addition, if you already need help reaching your calorie goals daily, it’s unlikely that you’ll come close to meeting your recommended calories if you’re fasting for extended periods.
However, following the 16/8 intermittent fasting method while still consuming enough calories for your goals can be a viable option. You can enjoy the benefits of intermittent fasting while working towards your muscle-building goals.
First, if you are doing weight training while fasting, start with lighter weights and do fewer repetitions than usual for the first few sets. This will help avoid any dangers associated with lifting too heavy too quickly after not eating for an extended period.
Consider widening your eating window with intermittent fasting to support your bulking goals. This allows more opportunities to consume the necessary calories and nutrients for muscle growth.
Calculate your daily caloric needs, including the additional calories necessary for muscle growth, and aim to reach that surplus within your eating window.
Engage in regular strength training exercises to stimulate muscle growth. Focus on compound exercises that target multiple muscle groups, such as squats, deadlifts, bench presses, and rows. Make sure that your workouts incorporate progressive overload, which means gradually increasing the weight and intensity of your workouts. This is vital for muscle development.
Regularly track your progress, including body measurements, strength gains, and feelings. Then, adjust your eating window, caloric intake, and macronutrient distribution as needed to optimize your results.
How Long Can You Fast Without Losing Muscle?
Research on fasting and muscle loss can explain how long you can fast without losing muscle. In a study conducted in 2010, researchers found that healthy men who underwent 24 days of alternate-day fasting didn’t show any significant losses in body weight, fat mass, or lean body mass.
This suggests that people can fast longer without significantly reducing their muscle mass. However, further research is needed to draw more apparent conclusions about the effects of extended fasting on muscle mass.
Final Thoughts
Finally, can you intermittently fast and gain muscle? Intermittent fasting can help push your physical endurance and strength to the limit. It helps build critical muscle mass when combined with the proper diet and workout regimen.
It may seem easy to start, but to utilize intermittent fasting while maintaining your health and safety, talk it over with a healthcare professional first; they’ll help you design a program that works for you.
Moreover, stay hydrated throughout your fasts by consuming plenty of healthy fluids like water and herbal teas.
Maintain consistency – remember it’s a marathon, not a sprint! Devote time each day to start implementing intermittent fasting into your routine, allowing your body to adapt gradually as you become more comfortable fasting for extended periods.
If you stick with it, don’t be surprised if you suddenly find yourself in top muscular condition with the desired results you were after!
