Intermittent Fasting And Muscle
Two ground-breaking studies have recently been published on the effects of intermittent fasting on males. One group of researchers studied the effects that 16 hours of intermittent fasting had on males that lift weights. They found that muscle mass stayed the same, fat mass decreased significantly, and the males who fasted for 16 hours a day burned more fat for fuel compared to the control group that only fasted for 12 hours.
Another study showed that combining 20 hours of fasting with resistance training resulted in an increase in muscle mass, strength, and endurance, and this was achieved by eating ~650 calories per day less than normal.
The benefits of intermittent fasting translate to untrained overweight and obese individuals as well. One study published in Obesity Reviews found that eating fewer calories is effective for fat loss, but it does come with some muscle loss. However, if the subjects fasted for 24 hours and ate as much as they wanted on the next day for a period of 12 weeks, they lost significantly less muscle mass.
Yes you read that correctly 24 hours of intermittent fasting without any resistance training and these subjects were able to preserve more muscle mass than the subjects that ate fewer calories every day without fasting at all. This finding contradicts our common sense, but when we dig deeper into autophagy we can find the mechanism behind this result.
How To Do Intermittent Fasting Safely
Fasting for weight loss can be effective, but you need to do it safely. Here’s what you should know first.
Fasting for weight loss can be effective, but you need to do it safely.
You’ve probably heard of intermittent fasting, the popular diet that involves restricting the hours during which you can eat. It’s heralded as a weight loss method, and research suggests that it can also boost your immune system, cure high blood pressure and more.
Intermittent fasting is well-known, but it’s only the tip of the iceberg when it comes to fasting diets in general. There’s practically infinite ways you can adopt a fasting regime that suits your own lifestyle and health needs. Let’s take a look at all the different fasting diets, the health benefits they may bring and how to do them safely.
Tips And Tricks About Fasting
#1) Dont freak out! Stop wondering: can I fast 15 hours instead of 16? or what if I eat an apple during my fasted period, will that ruin everything? Relax. Your body is a complex piece of machinery and learns to adapt. Everything is not as cut and dry as you think.
If you want to eat breakfast one day but not another, thats okay. If you are going for optimal aesthetic or athletic performance, I can see the need to be more rigid in your discipline, but otherwisefreaking chill out and dont stress over minutiae!
Dont let perfect be the enemy of good when it comes to your intermittent fasting plan.
#2) Consider fasted walks in the morning. I found these to be very helpful in reducing body fat, and also gave my day a great start to clear my mind and prepare for the day.
Simply wake up and go for a mile walk. Maybe you could even start walking to Mordor?
#3) Listen to your body during your strength training workouts. If you get light headed, make sure you are consuming enough water.
If you notice a significant drop in performance, make sure you are eating enough calories during your feasting window.
And if you feel severely off, pause your workout. Give yourself permission to EASE into intermittent fasting and fasted workouts. This is especially true if you are an endurance athlete.
#4) Expect funny looks if you spend a lot of mornings with breakfast eaters.
#7) Track your results, listen to your body:
This is just one tool that can contribute to your success.

How Can I Suppress Hunger During Intermittent Fasting
Eat high-fiber foods, such as nuts, beans, fruits and vegetables, and high protein foods, including meat, fish, tofu, or nuts, during your eating window, Varady advised. Chewing high-fiber gummies can also help.
Drink lots of water. People tend to think they’re hungry, when they are really just thirsty, she said.
Go for black coffee or tea, or cinnamon or licorice herbal teas. These beverages may have appetite-suppressing effects, Varady noted.
Watch less TV: I know this sounds strange, but while you are watching TV, you are bombarded with dozens of ads for food. This can make you feel hungry, when in actuality, you are not hungry at all, she said.
Remember, being “a little hungry” is the best thing that can happen to you, wrote Madelyn Fernstrom, health and nutrition editor at NBC News, calling it a “true mind-body connection” that helps you recognize fullness.
Recommended Foods And Tips
While the 16:8 intermittent fasting plan does not specify which foods to eat and avoid, it is beneficial to focus on healthful eating and to limit or avoid junk foods. The consumption of too much unhealthful food may cause weight gain and contribute to disease.
A balanced diet focuses primarily on:
- fruits and vegetables, which can be fresh, frozen, or canned
- whole grains, including quinoa, brown rice, oats, and barley
- lean protein sources, such as poultry, fish, beans, lentils, tofu, nuts, seeds, low fat cottage cheese, and eggs
- healthful fats from fatty fish, olives, olive oil, coconuts, avocados, nuts, and seeds
Fruits, vegetables, and whole grains are high in fiber, so they can help keep a person feeling full and satisfied. Healthful fats and proteins can also contribute to satiety.
Beverages can play a role in satiety for those following the 16:8 intermittent fasting diet. Drinking water regularly throughout the day can help reduce calorie intake because people often mistake thirst for hunger.
The 16:8 diet plan permits the consumption of calorie-free drinks such as water and unsweetened tea and coffee during the 16-hour fasting window. It is important to consume fluids regularly to avoid dehydration.

Should You Do Intermittent Fast Every Day
If you can follow a daily intermittent fasting schedule, your body gets used to the cycle, and you may not feel as hungry as you do when you start. Your body adapts to the change in eating patterns.
Lets face it we are used to eating several times a day. And if you gradually ease into intermittent fasting, you will find it gets easier.
However, suppose you feel that you simply cannot do this. In that case, you can try expanding your eating window to 12 or 14 hours and eating a lot of vegetables and fruits, which are filling and yet not very calorific.
Do you find this very restricting? Then opt for skipping meals occasionally. Whatever method you adopt, know that eating fewer calories and eating healthier will enable you to lose weight and improve your health.
Simplifying The Mechanisms Behind The Benefits: Autophagy Ketones And Fat Loss
Intermittent fasting is so powerful because you can use it to restrict calories, induce ketosis, and activate the processes of autophagy that are brought about by protein restriction and starvation.
If this scientific jargon is throwing you off, think about what it takes for you to clean your room. You may clean it in your spare time or have a set time on the weekend to do it, but what happens when the weekend comes?
Tasks or chores come up and you prioritize something else. After a week without cleaning, your room is just a bit dirtier than usual, but after a month of being too busy to clean, your room is filthy.
This is what happens to our cells when we eat three or more meals a day that completely fulfills our calorie needs every day. Even by eating the healthiest of foods, your cells still can get backed up with non-essential proteins and toxic compounds so what can you do?
To make sure that you clean your actual bedroom, you fast not from food but from being consumed by other obligations. To make sure that your cells can clean themselves, you must fast from food.
This fasting process will not only activate this clean process for your cells, but it will increase your ketone production and promote fat burning as well. Simply put, by adding intermittent fasting to your keto lifestyle, you can experience the benefits of keto more quickly along with the effects of autophagy.

How Much Weight Loss Can You Expect In A Month On Intermittent Fasting
Many factors go into how much weight you actually lose on intermittent fasting. Weight loss will depend on your current weight, metabolism, what you eat, and your activity levels. Obviously, if you follow a healthy eating pattern and exercise every day or a few times a week, it will help you shed weight faster.
Intermittent fasting may enable you to lose between 0.51.5 pounds a week. In 4 weeks, you could lose anything between 26 pounds.
Longer Fasting Regimens 24 Hours Or More
I arbitrarily divide it at 24 hours but there is no physiologic reason to do so, other than for classification purposes. There is no magic dividing line.
We covered fasting regimens using periods less than 24 hours previously. The longer regimens are generally done less frequently. The major determinant of which fasting regimen is right for you is personal preference. Some people find longer fasts easier and some find them harder.
Most people find that hunger increases into day 2. At that point, hunger peaks and then gradually recedes. This is important knowledge if you are attempting a longer fast . It is easier to continue knowing that hunger gradually gets better.
This guide is written for adults with health issues, including obesity, that could benefit from intermittent fasting. Learn more.
People who should NOT fast include those who are underweight or have eating disorders like anorexia, women who are pregnant or breastfeeding, and people under the age of 18. Learn more.

Fasting On Alternate Days
Alternate-day fasting consists of fasting one day, then eating regularly the next. On this schedule, your caloric intake on fasting days will be roughly 25% of your usual calories. For example, if you typically eat a 2,000-calorie diet, youll limit your calorie intake to 500 calories during your fasting time.
So Which Intermittent Fasting Schedule Is Best For Weight Loss Whichever One You’ll Actually Stick To Tbh
In short, the one that’s easiest for you to follow. “It is all about sustainability for the individual,” says Lemein. “If one of these diets work well for you and your lifestyle and preferences, then you will likely see some success. If not, then you’ll likely not see the results you’re are looking for, as the sustainability piece will not be there.” That means picking a diet that work best with all the lifestyle factors you need to consider, like your work schedule, family dynamic, living situation, commute time, and travel commitments, notes Lemein.
It’s worth pointing out, though, that the 16:8 diet seems to be the most doable for a lot of people who are into IF. The 16:8 method also scores points for preventing overeating at night, which can often be a big obstacle for weight loss. And sticking to an eight-hour eating window during daylight hours allows your metabolism to run as itâs supposed toâyou fuel up for energy during the day , and stop eating for rest and recovery at night, per a 2017 article in the journal Nutrition Reviews.
The bottom line: All intermittent fasting schedules may lead to weight loss if you can follow them sustainably, and the 16:8 method may be the easiest way to follow an IF diet.
When Can I Eat On The 1: 8 Diet
You can pick an 8 hour window to suit your day. So, for example it could be between 10am 6pm or 11am 8pm and so on. Plus, you can still drink tea and coffee outside of those hours too, although because of the benefits of drinking water you are also encouraged to stay as hydrated as possible.
Most people choose to fast through the night, and opt to eat their first meal at about 11am or in the middle of the day.
Tom says, The most common hours adopted for the eating period is 12 till 8pm. The reason for this is because people arent normally that hungry in the morning, you dont want to be consuming too many calories during the evening and this allows us to eat our lunch and dinner as well as a healthy snack.
What Can I Eat While Intermittent Fasting
During the times when youre not eating, water and zero-calorie beverages such as black coffee and tea are permitted.
And during your eating periods, eating normally does not mean going crazy. Youre not likely to lose weight or get healthier if you pack your feeding times with high-calorie junk food, super-sized fried items and treats.
But what Williams likes about intermittent fasting is that it allows for a range of different foods to be eaten and enjoyed. We want people to be mindful and take pleasure in eating good, nutritious food, she says. She adds that eating with others and sharing the mealtime experience adds satisfaction and supports good health.
Williams, like most nutrition experts, regards the Mediterranean diet as a good blueprint of what to eat, whether youre trying intermittent fasting or not. You can hardly go wrong when you pick complex, unrefined carbohydrates such as whole grains, leafy greens, healthy fats and lean protein.
Is 16/8 Intermittent Fasting Right For You
16/8 intermittent fasting can be a sustainable, safe and easy way to improve your health when paired with a nutritious diet and a healthy lifestyle.
However, it shouldnt be viewed as a substitute for a balanced, well-rounded diet rich in whole foods. Not to mention, you can still be healthy even if intermittent fasting doesnt work for you.
