I recommend utilizing a hour fast with an 8-hour eating window for beginning intermittent fasting. You will begin with a hour fast. The good thing is that the hours you are sleeping count toward your fasting window.

What has worked best for me is ending my eating window 2 hours before bed, sleeping 8 hours a night, skipping breakfast, and not eating my first meal until mid-afternoon. I like that approach because I am not a breakfast person and my hunger levels are higher after work. The best way to determine your windows is to look at your daily schedule and see what times would work for you.

During your fast, especially in the first week or two, you may experience hunger pains. This feeling is normal because your body is used to eating during the day and not used to fasting.

However, here are some things you can do to help you get through your fast:. For some reason, black coffee acts as an appetite suppressant.

Working out fasted should have no effect on your gym performance, especially once you get used to it. Training while fasting can even give your pre-workout a boost.

With nothing in your system, your pre-workout will hit you harder. One thing I recommend doing if you plan on training fasted is to consume g of BCAAs before training. BCAAs will help to prevent any muscle from being broken down during your session.

Lose Fat Is Intermittent Fasting a Fit For Your Fat-Loss Go HOW TO DETERMINE YOUR FASTING AND FEEDING WINDOWS I recommend utilizing a hour fast with an 8-hour eating window for beginning intermittent fasting.

WHAT TO EAT During your fast, especially in the first week or two, you may experience hunger pains. However, here are some things you can do to help you get through your fast: 1.

Black Coffee For some reason, black coffee acts as an appetite suppressant. Zero-Calorie Beverages I prefer sparkling waters. The carbonation helps with feeling full.

Wake up: Cup of black coffee 11 a. In fact, the effects are so minor that they may not even exist. As promising as calorie cycling sounds in theory, the research has been fairly underwhelming. If you follow a good hypertrophy training program, eat a good diet, and live a healthy lifestyle, you can build an impressive amount of muscle.

That way, you can build muscle steadily throughout the day. instead of intermittent fasting. That was disproven, and it was more of a fat-loss concern anyway. When it came to bulking , bodybuilders worried that if they spent too much time fasting, their bodies would begin to eat away at their muscle mass catabolism.

That was also disproven. Intermittent fasting is okay for maintaining muscle mass, even in a calorie deficit. But to take advantage of that opportunity, you also need to be on point with your diet.

Norton found that when we eat a meal with enough protein in it, it triggers a surge of muscle growth that gradually slows down over the course of around six hours, like so:.

This Nortonian model of muscle growth brings up some questions. First of all, if you miss a muscle gain opportunity, can you make up for it later by eating a meal that has extra protein in it? For example, what if we could do something like this:.

Unfortunately, catching up is not possible. If you have more than 40 grams of protein in a meal, no additional muscle growth is triggered.

Twenty grams of protein still stimulates a lot of muscle growth. Your breakfast will still allow you to build muscle just fine, and the larger amount of protein with dinner will still be fully digested. This raises another question. How often can we stimulate muscle protein synthesis?

Could we eat protein all day long, perpetually maintaining peak muscle growth conditions? What about something like this? Layne Norton tested this idea and discovered that we can only trigger muscle growth once every four hours or so. How controversial is this research?

Could it be wrong? One of those finer details is that these spurts of muscle growth seem linked to one specific component of protein leucine , not our overall protein intake. For example, you can get maximal muscle growth with just 27 grams of whey protein, whereas you might need more like 50 grams of rice protein in order to get the same effect.

To quote Schoenfeld:. The anabolic effects of a meal last a maximum of 6 hours or so. Thus, consumption of at least 3 meals spaced out every 5 to 6 hours would seem to be optimal for keeping protein synthesis continually elevated and thus maximizing muscle protein accretion.

This hypothesis needs further investigation in a controlled long-term study. Now, one discrepancy to note is that Norton recommends eating every four hours, whereas Schoenfeld recommends eating every 5—6 hours.

While their recommendations are slightly different, their understanding of the research is not. Norton is simply erring on the side of eating more often, whereas Schoenfeld is erring on the side of eating a little bit less often.

Both lifting and consuming protein increase muscle protein synthesis. After a good workout, muscle-protein synthesis will shoot up and then slowly decrease over the course of a few days. This is a pretty classic bodybuilding diet, where you eat 4—5 meals per day and have an especially big post-workout meal.

Fairly simple, and fairly ideal. Does this mean you should be eating 4—5 meals per day? You can trigger muscle growth just as easily with snacks, such as a bit of greek yogurt, a protein bar, a protein shake, or cottage cheese.

These snacks may make your overall diet easier. Just have breakfast early, have dinner late, and make sure your meals have at least twenty grams of protein in them.

One of the main purported benefits of intermittent fasting is increased growth hormone production. If we eat steadily throughout the day, we miss out on that extra growth hormone. Should eat more often to get more muscle-protein synthesis, or should we fast to get more growth hormone?

Which advantage is greater? Researchers have compared different meal schedules and concluded that having several meals spread out over the course of the day builds more muscle than intermittent fasting study. However, once again, the difference is going to be very small.

So small that it may not even be noticeable. In fact, some studies comparing intermittent fasting against a more normal meal schedule found identical amounts of muscle growth study. Eating more frequently may result in leaner gains.

Eating more frequently makes it much easier to eat enough calories to bulk up. And keep in mind that if you have a smaller stomach or faster metabolism , eating more frequently is absolutely essential while bulking.

It clearly shows that if our workouts, diet, protein intake, and sleep habits are on point, we can make good gains while eating anywhere from 2—7 meals per day.

This means that intermittent fasting is still a valid option, even while bulking. Furthermore, some intermittent fasting diets take some of our criticisms into consideration. The main disadvantage of fasting while bulking is the lack of muscle protein synthesis.

However, what if it were possible to stimulate muscle protein synthesis while fasting? This would allow you to get the best of both worlds, right? Supplementing with leucine or branched-chain amino acids BCAAs sort of allows you to do that.

They contain enough of the amino acid leucine to trigger muscle-protein synthesis, but they contain so few calories that Martin Berkhan still considers it fasting. The strategy works better while cutting, as the BCAAs prevent muscle loss and improve workout performance.

There are also types of intermittent fasting where you only fast for one hour period each week. John Berardi used when testing out an extreme bulking plan on the fitness blogger Nate Green Bigger, Smaller, Bigger. So, how can we min-max our muscle-building results based on all of this research?

I have two intermittent fasting protocols you might want to experiment with. You can still eat several times per day, just keep your protein intake high and your calorie intake low. This is how Jared gained 33 pounds in three months, as shown above.

Monday: full-body workout, eat big Tuesday: rest, eat big Wednesday: full-body workout, eat big Thursday: rest, eat big Friday: fully-body workout, eat big Saturday: rest, eat big Sunday: take a break from eating big.

Skipping breakfast increases morning productivity, but you miss out on an opportunity to stimulate muscle growth. This light breakfast could be a protein shake and some fruit, a protein bar and a latte, or even just a smoothie.

These half-fasts are what Dr. Layne Norton recommends to bulkers who are curious about intermittent fasting:. If you want some of the benefits from intermittent fasting but want to optimize muscle mass, I would advise a different type of fast.

Rather than cutting out all calories, simply restrict carbs and fats during your fasting window, but continue to evenly distribute your protein intake throughout the day.

This is what we recommend to our members, and this is how I managed to gain 55 pounds over the course of a couple of years:. A new study by Tinsley et al. looked into the results of using intermittent fasting for muscle gain.

They compared muscle growth between different groups of women, some of whom were eating steadily throughout the day, others who were intermittent fasting using a protocol. I reached out to Eric Trexler, PhD, for his thoughts on what to make of this for guys doing a bonafide bulk eating in a larger calorie surplus and gaining closer to a pound per week.

He told me the following:. The primary benefit seems to be satiety management when caloric intake is low. As far as my own take on this, I think I might need to adjust my graphs to show a larger boost in muscle-protein synthesis from lifting weights and a smaller boost in muscle growth from individual meals.

We have a brand new study comparing the effects of protein distribution on muscle growth. In this study, the participants were put on a twelve-week weight training program. Half the participants were given a breakfast that was extremely low in protein, whereas the other half were given a normal breakfast containing an average amount of protein.

Both groups ate the same amount of protein overall, and both diets had the same macronutrients. The only difference was the schedule. It also yielded larger increases in strength. Both the intermittent fasting and the control group were given instructions about how to eat a good diet.

Both groups lost a similar amount of weight—around 2 pounds. And both groups lost a similar amount of fat. But the intermittent fasting group started to subconsciously move a little bit less, slightly reducing their metabolism. The main finding, though, was that the intermittent fasting group lost more muscle mass.

Maybe it was because they were moving less, stimulating their muscles a little bit less. Up until running this study, he was doing intermittent fasting himself. But after seeing these results, he decided to go back to eating more meals. A meta-analysis by Ashtary-Larky and colleagues found that intermittent fasting might help people lose more fat while cutting study.

Most of these health benefits are connected to the calorie deficit. Most people find that intermittent fasting reduces their appetite, causing them to eat less food. Most people are overweight, so eating less food improves several different health markers.

Furthermore, if intermittent fasting causes a skinny guy to lose weight or prevents him from building muscle, it could be bad for his health. A diet that interferes with that could be bad for us. People tend to eat less food while intermittent fasting.

If you can eat enough calories to gain weight, can intermittent fasting allow you to bulk up more leanly? Intermittent fasting is an extreme example of calorie cycling. To understand how intermittent fasting affects fat storage and muscle growth, first, we need to understand how regular calorie cycling affects fat storage and muscle growth.

The first thing we need to do is distinguish between bulking and cutting. You can use calorie cycling to help with either goal, but the effects are rather different. Your body will be primed for muscle growth after a good workout, and then that muscle growth will gradually slow down as time passes, usually grinding to a halt within 48 hours.

The other thing to keep in mind is that any calories which cannot be invested in muscle growth will be stored as fat. However, this is a compromise. You might improve your gains by lining up your calorie intake with your muscle growth potential, eating extra calories in the meals following a workout, then easing back on the calorie surplus afterwards.

It makes sense in theory, but the evidence is still fairly weak. You still want to be steadily building muscle all day long, all week long, and all month long.

You might not even notice it. Your muscles are getting bigger, too, stretching your fat thinner and giving your body more structure. Even if you gain some extra fat, you might not lose any muscle definition.

The fat may even help you look buffer and fuller. Bulk more slowly. That will slow your rate of weight gain , leaving fewer surplus calories to spill over into fat gain.

Instead of gaining one pound per week, gain 0. Intermittent fasting doubles down on calorie cycling. The misconception comes from the fact that in order to gain weight, you need to be in an overall calorie surplus.

That means during your feeding periods, you need to make up for all the calories you missed while fasting. When you try to catch up on those calories, some will spill over into fat storage. What happens is that you lose a bit of fat while fasting, then gain even more during the feeding window.

In this case, with such a small overall surplus, you miss out on some of the extra testosterone, nutrients, and cellular signalling, so your growth potential slows down, like so:. They might be able to get results that look something like this:. However, to say that their programs are designed for this would be to sell them short.

Even the LeanGains intermittent fasting protocol is designed for fat loss and muscle maintenance , not for bulking. To quote the guy who created it, Martin Berkhan:.

If you combine hypertrophy training with a calorie deficit and a good cutting diet , you can lose fat while keeping most of your muscle.

Some skinny-fat beginners are even able to gain muscle while losing fat. This is true whether you use intermittent fasting or not.

The advantage of intermittent fasting is that it makes it easier and arguably more enjoyable to get into a calorie deficit. In fact, the effects are so minor that they may not even exist. As promising as calorie cycling sounds in theory, the research has been fairly underwhelming.

If you follow a good hypertrophy training program, eat a good diet, and live a healthy lifestyle, you can build an impressive amount of muscle. That way, you can build muscle steadily throughout the day. instead of intermittent fasting.

That was disproven, and it was more of a fat-loss concern anyway. When it came to bulking , bodybuilders worried that if they spent too much time fasting, their bodies would begin to eat away at their muscle mass catabolism.

Building Muscles and Losing Fat Are Physiological Processes that Occur Simultaneously The body is in a state of constant growth or breakdown.

Intermittent Fasting Is the Best Diet to Build Muscle and Burn Fat All at Once Intermittent fasting is a diet that optimizes when food should be eaten and when exercise should be done to achieve maximum results when it comes to losing fat and building muscle.

It is also based on the phenomenon of exercising on an empty stomach, which has two main advantages: Low insulin resistance promotes muscle building and reduces the risk of cancer.

To put it simply: Insulin is released the moment we eat something. Sugar enters the liver and muscles in the form of glucose and is stored there so that it can be used as a source of energy at a later point in time.

The problem is that if we eat too often and too much, our bodies become more resistant to insulin. Regular fasting also allows less insulin to be released over a long period of time, making our bodies more sensitive to the hormone.

This risk of heart disease, diabetes, and cancer is reduced too Stolzenberg-Solomon et al. For example: a. Strength training should ideally look like this: 30—60 minutes Short and intense 6—12 reps per set Max.
