Fasting Helps Weight Loss

How to do Intermittent Fasting: Complete Guide

Fasting can be a safe way to lose weight as many studies have shown that intermittent fasting fasting that is controlled within a set number of hours allows the body to burn through fat cells more effectively than just regular dieting.

Intermittent fasting allows the body to use fat as its primary source of energy instead of sugar. Many athletes now use fasting as means to hitting low body fat percentages for competitions.

What Is Intermittent Fasting And Does It Really Work

The best diet is the one where you are healthy, hydrated and living your best life.

By Crystal Martin

Generally, intermittent fasting is a diet strategy that involves alternating periods of eating and extended fasting. Theres quite a bit of debate in our research community: How much of the benefits of intermittent fasting are just due to the fact that it helps people eat less? Could you get the same benefits by just cutting your calories by the same amount? said Courtney M. Peterson, Ph.D., an assistant professor in the Department of Nutrition Sciences at the University of Alabama at Birmingham who studies time-restricted feeding, a form of intermittent fasting.

We asked Dr. Peterson and a few other experts to help us sort out the real from the scam on intermittent fasting.

How Much Weight Can You Lose On 1: 8 Diet

To lose weight on the 16:8 diet, its important to match the fasting with healthy eating and exercise. If done so correctly, theres a typical weight loss of around seven to 11 pounds over a ten week period. This is according to a review of 40 different studies published in Molecular and Cellular Endocrincology who found that on average, someone weighing just over 90kg would lose 5% of their total body weight in the ten week period.

A 2018 study published in the Journal of Nutrition and Healthy Eating revealed that the 16:8 diet plan can help people lose weight, without having to count calories as the 8-hour fast produces the same kind of calorific restriction and weight loss.

However, whether theres a distinct weight loss advantage achieved on the 16:8 diet compared to other diets remains to be seen. Some studies have demonstrated that theres almost no difference between people who do intermittent fasting compared those who count calories and cut back on unhealthy food.

Set Up And Getting Started

DoFasting is available as a free Android app and iPhone app, although it requires a subscription to use. There is no free trial. When we first tested the app in early 2020, there was no option to purchase a subscription through the App Store or Google Play Store. You had to create an account and pay for it online. This has changed. Paying through one of the app stores is a better option for consumers because it gives them more control over canceling. The option to sign up and pay online still exists. If you pay for the account that way, you have to send an email to request cancelation.

To create an account with DoFasting, you answer a series of questions, including whether you’re male or female, when during the day you feel hungriest, what time of day you eat your meals normally, how much you work out, whether you work and if it’s seated work, plus height, current weight, and desired weight.

When you pay for your account, be prepared for upsells. In testing, we turned down at least four offers. Don’t you want to pay for a personal nutritionist, and fiber packets? How about some chocolate or vanilla flavored Keto Fuel, or a lifetime subscription? Lines like, “We are probably losing money on this deal” make it sound like they’re selling snake oil.

When Should I Exercise

Pin on Intermittent Fasting

When Varady and her colleagues conducted a study that combined alternate day fasting and exercise, they allowed the participants to pick whether they wanted to exercise on a feasting or fasting day, and found there was no strong preference one way or the other. But the researchers were surprised the dieters actually reported feeling more energetic on fasting days.

I lost over 5 pounds, but more than that I gained so much knowledge. It’s easier now to want to eat healthier even just small tweaks…Colleen Frazier

Won’t You Just Eat More Later

You might. Still, you should try to eat a healthy amount of food and not stuff yourself after a fast. Quality still counts. But even among people who eat the same number of calories, those who fast tend to have lower blood pressure, higher insulin sensitivity, more appetite control, and easier weight loss.

That being said, exercise before you eat because people get hungry about half an hour after they finish working out and may find it too hard to stick to their plan if they cant eat anything at all afterwards, Varady noted.

If youre on the 16:8 plan, exercise before or during your eating window. If youre doing alternate day fasting and are exercising on your 500-calorie day, save food for after your exercise session.

What Are The Benefits Of Fasting

There’s a lot of preliminary research on fasting that points to some pretty promising benefits, but many more studies are needed to back up the claims.

One major benefit of fasting is that it helps promote autophagy — a process in which your cells essentially “take out the trash” by removing dysfunctional components. Increased autophagy can possibly regenerate the immune system and increase your cell’s protection against stress.

Some research suggests that fasting can also lower blood pressure, as well as making your body more sensitive to insulin. Being more insulin-sensitive means that you’ll store energy from food more efficiently, and get less hungry between meals.

Now to the main reason people try fasting — to lose weight. While one study showed that both fasting and caloric restriction had the same weight loss results, losing weight is a highly individual journey. If you’ve been struggling to find a way of eating that helps you be your best self, you may want to give fasting a try.

Will Regular Modified Fasting For Three Days Cause Muscle Wasting

Pin on Health

A lot of people worry that fasting for any length of time will make their body start using up muscle for fuel. But think about that logic for a second: why would mother nature cannibalize your muscles during times of food scarcity? In the wild, youd need those muscles more than ever, to search for food, run from predators, etc.

During a fast ,10 your body will use fat stores for energy first. Thats why they exist! Youd have to fast for a very long time, with zero calorie intake, to start using muscle for energy. In one large-scale study,11 where participants fasted 35 out of 70 days, they lost an average of 6% body mass and 11% fat mass. Translation: your muscles are safe!

As fasting expert Dr. Jason Fung says,12

If periodic starvation caused our metabolism to decrease, then we would have less energy to hunt or gather food. With less energy, we would be less likely to get food. So, another day passes, and we become even weaker, making us even less likely to get food a vicious and unsurvivable cycle.

Dr. Jason Fung

The root of this fear may come from the fact that our basal metabolic rate DOES fluctuate based on calorie increases and restrictions. If you usually eat 2,000 calories per day and restrict to 1,500 calories per day, your basal metabolic rate will decrease to match your caloric intake. However, as Fung adds,

Does Intermittent Fasting Work

While intermittent fasting may be a popular trend in the diet world these days, those trying to lose weight or improve their overall health should know that it can be a hard plan to stick to.

The approach alternates between periods of fasting and non-fasting during a particular time period. Intermittent fasting is not about deprivation, but about splitting up your calories differently than the three-square-meals a day plus a snack routine.

The reason IF is thought to be effective in weight loss is because it increases your bodys responsiveness to insulin. Insulin, a hormone that is released when you eat food, causes your liver, muscle and fat cells to store glucose. In a fasting state, blood glucose levels drop, which leads to a decrease in insulin production, signaling your body to start burning stored energy . After 12 hours of fasting, your body runs out of stored energy and begins burning stored fat.Two of the more well-known IF plans

  • 5:2 diet: Eat normally, but healthfully for five days of the week and consume only 500 to 800 calories on two nonconsecutive days. Women usually aim for closer to 500 and men around 800 calories. Some might opt to split their calories into two or three mini meals.

  • Alternate days: Eat normally one day, then fast the next, and repeat for the rest of the week.

Why Should You Fast

First, lets talk about the benefits of fasting. Fasting is a great way to give your system a reset and help your bodys natural processes work more efficientlysuch as energy production, metabolism, and digestive function .

For most people, during the day, youre in the fed state. This means your body is working hard to digest, absorb, and assimilate all the nutrients from the foods you eat. But when you enter a fasted statewhich simply means youre not taking in any caloriesyour body can shift gears and use your energy to focus on the functions that are prioritized after digestion, such as burning fat and boosting metabolism .

This is why the fasted state is often referred to as the fat-burning state. And although you might expect to feel tired or weak without eating, many people experience more energy, less brain fog, and improved focus and concentration when they enter the fasted state.

How Often Can You Do Intermittent Fasting

This also up to you. There are no set rules on how often you can do intermittent fasting for. You can have an initial phase where you hit your goals after a couple of weeks. Then have a break for say 3 months and eat the routine way for the 3 months.

Then, re-start intermittent fasting again for another 3 months, have a break for 3 months and do the same thing again.

You can use a 2 month ON, 2 months OFF model, 4 months ON, 4 months OFF . Do this repeatedly. No rigid rules about how often you can fast intermittently.

If the question is about how often to fast during the week, it would depend on the IF plan you adopt. The 5:2 requires you to fast 2 days a week . Alternate day fasting is as the name suggests, every other day.

The 2 days you fast in the 5:2 plan are not actually a total fast. It only requires you to hold back on your calories to 500 Calories for those 2 days.

The true 24-hour fast may require you to do this twice or three times a week, if you can handle that frequency.

If you cant, even one day a week is okay until you get comfortable with it and you can then try 2 days a week.

Even one day a week is certainly better than what you are currently doing. It will still work. Its just going to take longer.

So, if you want to know how many weeks to do intermittent fasting, all I can say is theres no one size fits all approach.

What Are The Possible Side Effects

How to do Intermittent Fasting if You Workout in The Morning

There can be a number of possible side effects of intermittent fasting.40 Heres what to do if you encounter them:

  • Hunger is the most common side effect of intermittent fasting. This may be less of an issue if youre already on a keto or low-carb, higher-fat diet.41Learn more
  • Constipation is common. Less going in means less going out. However, keep in mind this is a normal response to eating less. It is not a concern and shouldnt require treatment unless you experience significant bloating or abdominal discomfort. Standard laxatives or magnesium supplements can be used, if needed.
  • Headaches are common and tend to disappear after the first few times on fasts.42 Taking some extra salt often helps mitigate such headaches.43
  • Mineral water may help if your stomach tends to gurgle.
  • Other possible side effects include dizziness, heartburn and muscle cramps. Learn more

A more serious side effect is the refeeding syndrome. Fortunately, this is rare and generally only happens with extended fasts when one is undernourished.44

Since most of these side effects are manageable, they do not mean you have to stop your fast. However, if you truly feel unwell, are excessively dizzy, profoundly weak or have other severe symptoms, then you should break your fast.

Just remember to go slowly when you break it and prioritize fluids and salt . And of course, if the symptoms persist, see your doctor immediately.

Why You May Not See Results

Although there is research supporting the effectiveness of intermittent fasting, there are many reasons you may not see results. It may sound counter-intuitive, but you may not be eating enough calories during your fasting window. If you severely restrict calories, it can backfire. Sudden under-consumption can lead to metabolic adaptation, a process where your body becomes more efficient at using energy and storing fat which means youll burn less calories. The goal is not to count calories and cut them, its to eat minimally processed, nutritious foods during your eating window until you are full.

If you eat ultra-processed, energy-dense foods during your meals, that could be another reason why youre not getting the results you desire. Fasting can help you burn fat, but it doesnt mean that its magic! Remember to fill your plate with lean proteins, complex carbs, and healthy fats.

Finally, make sure you drink plenty of water during your fasting window. Hydration helps you feel full and satiated, and its easy to mistake thirst for hunger. If youre not hydrated when you approach your eating window, you may be prone to choose and eat ultra-processed foods.
