So How Do I Follow The Alternate Day Fasting Diet

How To Lose Weight Fast with Dr. Ken Fujioka | Ask the Expert

On the first day of the diet, you have just one fifth of you normal calorie intake that keeps your weight steady. As a guideline, women need around 2,000 calories a day, and men 2,500 calories a day for weight maintenance. This means on a fasting day when you are allowed just one fifth of this women should have 400 calories and men, 500 calories. However, the heavier you are, the more calories you need just to keep your weight steady.

You can get a more accurate picture of how many calories you need for weight maintenance by entering your weight, height and sex into the personal information on Weight Loss Resources database. Then divide this figure by five to calculate the amount of calories you should have on a fasting day.

To make it easier to stick to such a low calorie intake on fasting days, the Alternate-Day Diet recommends sipping ready-made meal replacement shakes that add up to your fasting daily calorie allowance. These have the advantage of being fortified with nutrients and help to remove the temptation to overeat. On the second day of the diet, you simply eat what you would normally eat. Then on day three, you do the same as on day one and so on.

So How Do You Water Fast Then

Everyone seems to invent their own rules and techniques for fasting, but hereâs what I felt sure about:

  • Donât eat ANYTHING. Even eating a small amount keeps digestion going which will make the fast torturous.
  • Drink however much water you feel like you need. Donât drink gallons, and donât just drink a thimble, and youâll probably be fine.
  • You donât need the electrolytes / vitamins, but they probably donât hurt.
  • Donât drink âjuice,â that stuff is terrible for you anyway.
  • Do as much activity as youâre comfortable with.
  • Sleep as much as you feel you need, but donât lie in bed just because your body is more tired than usual. What I found was that once I started moving or working, my body provided me the energy I needed. If I stayed inert, I got tired.

What Happens To Your Body When You Fast

Theres not a lot of evidence to show exactly what happens when we fast, says Nathalie Sessions, R.D., at Houston Methodist.

Theres only been a few viable scientific studies that have been done with humans on intermittent fasting, she tells MensHealth.

Most research has been conducted in animals, and human bodies dont function in the same way.

Many theorize that giving your body a break from eating helps your body repair damaged cells, a process known as autophagy, says Sowa. However, most of this research has been conducted in mice, so the science isnt 100 percent clear.

However, there is evidence that fasting lowers insulin levels, according to Sowa. Healthy adults experienced a decline in insulin levels after fasting, according to a 2005 study published in The American Journal of Clinical Nutrition. Insulin, a hormone made by the pancreas, regulates blood sugar and other hormones. Too much insulin has been linked to obesity and health conditions like heart disease.

How Does Water Fasting Help In Weight Loss

For the first two days during your water fasting phase, all you lose is the water weight. The fats start to burn from the 3rd day of water fasting phase. When you stop eating, your digestive system stops working. Your body slows down, except the brain and the heart. The stored fat is now broken down to provide energy for all involuntary and voluntary functions of the body. Water helps to get rid of the toxins and any waste present in the colon. This further helps you to lose a good chunk of weight. All this coupled with the right amount of daily exercise will help you to lose a considerable amount of flab.

The Duration Of The Fast

Most non-diabetic men experience significant success following a 16:8 fasting regimen daily or fasting intermittently for 24 hours. Women dont appear to have the same success with either of those regimens. Most women, especially at the start, achieve success doing 36 or 42 hours of intermittent fasting. It isnt a significant amount more than men, but its just enough to have a significant impact on our waistlines. In my experience, a 42 hour fast done three times a week has been the most successful fasting protocol for women looking to lose weight.

So Is Weight Loss Purely Down To An Overall Calorie Reduction

According to the author of the Alternate-Day Diet this isnt the case. Certainly, a total calorie reduction through fasting aids weight loss. However, this approach is based on the idea that fasting every other day also activates a skinny gene called SIRT1 that helps to boost weight loss further and adds to the health benefits of such a diet.

So How Does If Work For Weight Loss Exactly

How Much Weight Can I Lose When Fasting?

Intermittent fasting is about when you eat, says Charlotte Martin, MS, RDN, CPT, owner of Shaped by Charlotte, LLC. Depending on the IF approach, youre either shortening the eating window each day, or engaging in about 24-hour fasts one or more times a week. One of the most popular approaches is the 16:8 method, which is when you fast for an 16-hour window, like from 8 p.m. to 12 p.m. the next day.

Essentially, by restricting your food intake to a shortened time window, you naturally decrease your caloric intake and, in turn, can lose weight. âNot only are you taking in fewer calories, but youre also slowing down your insulin pump, which may boost fat burn,â explains Martin.

How Much Weight You Might Lose Through Intermittent Fasting

Intermittent fasting, in which you consume calories only during specific eating windows, ramps up the weight loss potential as well. A 2014 report from the journal Translational Research states that the average intermittent faster might drop between 0.55 and 1.65 pounds a week.

Besides losing weight, you can also reduce belly fat through intermittent fasting, says that same study. The rate of belly fat loss can be anywhere from 3 to 8 percent in up to 24 weeks.

Focus On The First 5% To 10%

Instead of saying, I need to lose 25 pounds, and overwhelming yourself with what seems like an impossible goal, look toward the health benefits that can come from even modest weight loss.

Set smaller, achievable targets, suggests Bennett. Losing only 5% to 10% of your total body weight can greatly improve your health and lower your risk for illnesses, such as type 2 diabetes, stroke, cardiovascular disease and certain types of cancer.

Why Does Intermittent Fasting Work

Experts believe that intermittent fasting is effective because it keeps us more in tune with the way that our bodies evolved. Traditional hunter-gatherer methods, which existed for minimally tens of thousands of years before the advent of farming, frequently involved extended periods between meals.

In contrast, the average American diet includes consistent eating across a 14-hour time frame each day. People usually include three meals a day with snacking in between. This allows your body to survive off of the calories that you put into your stomach each day. Its only when you run out of these calories that your body starts burning fat.

The theory behind IF is that it gives your body a longer time between meals than the average American diet. Youll need to use the energy in your stored fat when you run out of recently eaten calories.

What It Feels Like To Do Alternate Day Fasting:

How much weight can I lose in a month with intermittent fasting?

The first two weeks can be a challenge, but hunger or the lightheadedness that can come with not eating for an entire day actually wasnt a big issue for the participants after a while, Pieber noted. People often feel very energetic on fasting days, he added.

It can take the body 10-14 days to get used to metabolizing food in a different way, said Jamie Baum, director of the Center for Human Nutrition at the University of Arkansas.

As a nutrition scientist, Im never pro omitting food for the entire day, said Baum, who was not involved in the study. I always say if it works for you and its not eliminating a food group, Im supportive of it.

Alternate day fasting may be easier to stick with than a normal diet because people know they can eat whatever they want the next day and they dont have to count carbs or calories, she added.

Other experts werent so sure.

I think it would be really difficult for people to follow, said Krista Varady, a professor of nutrition at the University of Illinois, Chicago, who has been studying fasting for 15 years. Previous shorter-term studies found people struggled with zero-calorie alternate day fasting, she noted.

Still, some people find its easier to just not eat at all because even a small bite of food can cause them to want more, Varady said.

The Best Way To Maintain Weight Loss After A Water Fast

Again, in my experience the best way to maintain weight loss after water fasting is eating a diet focused on healthy proteins and filing the rest of your plate with foods that keep your blood glucose as stable as possible. Learn more in THIS BOOK and wear a Continuous Glucose Monitor

You may think initially that wearing a CGM means that youll need to stick to a keto or very low carb diet, but thats not the case at all. Many foods contain carbohydrates AND support stable blood glucose

And in THIS BOOK you will learn how eating a lettuce salad BEFORE carbs like pasta, white rice, brown rice, white bread, and other whole grains can nearly eliminate any health-damaging glucose spike too!

And again, to be honest if you have been yo-yo dieting for years your metabolism is probably damaged.. a 7 day water fast will not magically repair it. Many people are singing the praises of fasting as the holy grail of weight loss and healthy living Im not here to say that their experience is wrong, only that you need to be very cautious of their level of experience with fasting over the long term before you assign value to their opinions.

How Much Weight Can You Lose While Fasting

Let’s be clear about one thing: intermittent fasting doesn’t guarantee weight loss. In theory, you’ll consume less calories because you’re eating fewer meals, but it’s entirely possible to overeat while fasting.

You don’t want to gorge on a burger, fries, and shake right after fasting, says Sowa.

“In order to continue the benefits of the fast you want to choose foods that will not spike your insulin,” she says.

She recommends eating foods that are high in fiber and protein, like leafy green vegetables, eggs, and chicken.

Research about intermittent fasting for weight loss is mixed.

“Some studies have demonstrated that it can result in as much as a 7 percent weight loss in body weight,” says Sessions.

However, a randomized clinical trial of obese adults showed that intermittent fasting was no better than standard calorie restriction, according to a 2017 paper published in JAMA Internal Medicine.

Intermittent Fasting Weight Loss Faqs

Now that you know what intermittent fasting is and how to get started, its time to answer your other questions.

Below are answers to the questions frequently asked about intermittent fasting. These answers should help you and make getting started a lot easier.

How Much Weight Will I Lose?

The amount of weight you lose with fasting is determined by how often and long your fasts are, what you eat afterward, and other factors.

One study published by The American Journal of Clinical Nutrition found that average weight loss on an intermittent fasting diet was around 9lbs after 12 months, and weight loss was most successful in those who strictly adhered to their chosen diet.

Can I Work out While Fasting?

Yes, you can. In fact, doing the right type of workout while fasting will help you lose weight faster and even build muscle.

If you are a hardcore athlete who often exercises for an hour or more each day, intermittent fasting may not be the best choice for you as this amount of exercise requires fuel to keep you moving and build muscle. However, light to moderate intensity workouts 2 to 4 times a week should work with intermittent fasting.

The best workouts to do while fasting for weight loss are strength training workouts. This means anything from standard strength training to kettlebell or body weight workouts. Combine these with lighter forms of exercise like walking, jogging, or yoga.

What Is The Optimal Term Of Your Water Fasting

How Much Weight Can You Lose on a Water Fast?

And what about the optimal term of your water fasting? Yes, many people have practiced the 30-day fast weight loss approach, drinking only water and avoiding food at all. Some dieters start with a 5-14-day water fasting to prepare their bodies for this stress. Others stick to this diet for 22 and even 40 days at once everything depends on their goals. Technically, this is possible. Some people even claim that when the body doesnt have to spend energy for digestion, they have more energy for other things. Many of them claim even being able to continue their normal life go to work and have regular training sessions.

Your body can deal with only-water-diet-plan for a month, but it is extremely dangerous. Everything depends on your overall health, possible medical conditions and the amount of body fat you have. As it was mentioned above, this dietary pattern is not for everyone. If your aim is only to lose weight quickly, it also has one major minus. In the majority of cases, after such crazy and over-restrictive diets, people tend to regain their weight. And that is in addition to all the risks for your health, listed above.

However, there are short-term water fasts that arent dangerous for your body. Because of all the risks, health professionals dont recommend fasting for a period longer than 1-3 days. Remember that it is dangerous to stick to this dietary pattern for a longer period without medical supervision.

The Three Popular Approaches To Intermittent Fasting Are:

  • Alternate-day fasting Eat a normal, healthy diet one day and then completely fast or have one small meal the next day. Usually, the small meal is fewer than 500 calories.
  • 5-2 fasting Eat a normal diet five days a week and fast two days per week.
  • Daily time-restricted fasting Eat normally but only within an eight-hour window each day. For example, skip breakfast, but eat lunch around 11 a.m. and dinner by 7 p.m.

Reduce Stress And Improve Mental Health

The 16:8 diet help reduce cortisol levels and help reduce inflammation. Plus, since you wont be dealing with hunger for two days a week, its better for your mental health.

Those whove tried the 16:8 diet say how much more productive they are during fasting hours, spending less time stressing over food and more time channelling their energy into other beneficial tasks throughout the day.

Why Might Changing Timing Help

But why does simply changing the timing of our meals to allow for fasting make a difference in our body? An in-depth review of the science of IF recently published in New England Journal of Medicine sheds some light. Fasting is evolutionarily embedded within our physiology, triggering several essential cellular functions. Flipping the switch from a fed to fasting state does more than help us burn calories and lose weight. The researchers combed through dozens of animal and human studies to explain how simple fasting improves metabolism, lowers blood sugar levels lessens inflammation, which improves a range of health issues from arthritic pain to asthma and even helps clear out toxins and damaged cells, which lowers risk for cancer and enhances brain function.
