How Do Fasting Diets Work To Help Rev Weight Loss


The idea behind intermittent fasting is that it increases your metabolic rate, which helps you burn more calories. And by restricting the time periods during the day when you eat, you take in fewer calories each day.

Going into diet change, I knew there was only early evidence that fasting can lead to temporary weight loss, and that more research is needed especially on the potential long-term health effects of this diet. As it stands, experts warn that fasting may not be safe, or smart, for everyone. Fasting is not recommended for some groups, such as pregnant or lactating women, some people with diabetes, people dealing with eating disorders or issues such as low blood sugar, according to the Mayo Clinic. Thats why experts stress that its important to consult your healthcare team before trying any type of fast.

Despite the lack of comprehensive research on intermittent fasting, this eating style has helped me lose weight, regain my energy, and become more mindful about my eating choices.

Metabolic Flexibility The Key

After youve done a proper 21 day reset, the end result should be that youre now metabolically flexible.

Youre now fat adapted and you can easily switch fuel sources from the foods that you eat to your own body fat for energy. Thats when you get into what I like to call accelerated fat loss.

If you dont do a proper reset, and you still follow a standard western diet and you just jump in with intermittent fasting, that is the definition of metabolic inflexibility. And youre not going to see the results youre looking for.

This is where a lot of people find themselves. This is where you hear people say that they got headaches from fasting, they were starving the entire time, they didnt feel good, and they say it didnt work for them.

Yeah, no kidding. I couldve told you that.

Now the people whos taken the proper 21 day primal reset inside the Fat Loss Accelerator have all successfully unregulated their fat burning metabolism. Theyre metabolically flexible and they can easily fast for long periods of time without feeling hungry.

Which means that theyre able to burn more fat. Theyve also all been successful at being able to keep the weight off.

Now, how long will it take for you to start seeing results? It really depends how long you fast for, and how often. I always like to say that the longer you fast, the better.

So if youve been overweight for a long time, that means that youve also been insulin resistant for a long time.

/8you’re Not Taking It Slow

When people switch to a particular diet, one common mistake they make is jumping right to it and not taking it slow and steady.

With intermittent fasting, people do the same. Given that average human beings are used to eating after every few hours, leaping forward to a 24 hour fasting may not be the best solution. Rather one must start with a small fasting window and then gradually increase the frame.

If you go all in on your first try, you may not remain consistent and may lose track over time.

Greater Loss Of Belly Fat

Fasting may be more effective for reducing belly fat compared to other weight loss practices.

Concerns About 16/8 Fasting

Intermittent fasting, especially the 16/8 approach, is completely safe and beneficial. Contrary to common belief, moderate calorie restriction is a healthy practice that improves your metabolic health.

However, if youre using it to get into ketosis, it might not be enough to get you there. If your fasting goal is to enter ketosis, you also need to follow a keto diet.

How Long Does It Take To Start Losing Weight When You’re Doing Intermittent Fasting

There are a lot of factors that can contribute to how long it may take for the weight to start coming off. “Rate of weight loss will vary greatly from person to person depending on several factors, including: starting weight, the intermittent fasting approach used, the types of food consumed during the eating windows, and more,” says Martin.

If you end up reducing your overall caloric intake right away and you consistently eat fewer calories than you expend, then you should start losing weight immediately. “However, you likely wont notice any weight loss results for at least a couple of weeks,” notes Martin, adding that some weight loss in the beginning will “likely be water weight.”

Depending on the calorie amount you consume while intermittent fasting, you could experience an approximate one- to two- pound weight loss per week, which would mean it could take upwards of eight to 10 weeks to notice significant weight loss, says Kristen Smith, MS, RD, spokesperson for Academy of Nutrition and Dietetics.

If youre losing more than that? It could be a red flag. If you notice yourself losing a noticeable amount of weight during the first few weeks of following an intermittent fasting plan, you should likely re-evaluate your calorie intake to ensure you are consuming adequate nutrition to meet your bodys needs, says Smith.

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.

How Does 16/8 Fasting Work

Studies: Does Intermittent Fasting Work for Weight Loss? | 16:8, 18:6, & 20:4 Eating/Fasting Windows

Before we dive into the potential benefits of 16/8 intermittent fasting, lets take a closer look at what researchers have explored so far about the underlying mechanisms that may be at play.

When a person skips food for an extended interval, the bodys use of energy actually changes, explains Dr. , PhD, a neuroscientist with Johns Hopkins Medicine who studies intermittent fasting.

Someone who eats regularly throughout their waking hours is constantly replenishing their livers stash of glycogen, a stored form of glucose energy derived from carbs, he continues. When that supply isnt restocked, however, the body depletes glycogen fairly quickly. Those glycogen stores can get used up in about 10 hours if youre fastingmore quickly if you add in a workout, Dr. Mattson says.

Heres where things get interesting: Once glycogen stores are used up, the body starts scrounging for an alternative source of energy. At that point, it begins breaking down stored fats into substances called ketones to get the job done.

This metabolic switch does more than meet the bodys immediate energy needs, Dr. Steger says. In general, the switch from using glucose to ketones is a trigger pointit shifts your metabolism from focusing on storage and growth to being all about repair and replace, she explains.

What Does Intermediate Fasting Mean

People have made their own rules for the fitness trend but the most popular one is the 16/8 protocol. 16 represents the hours you have to fast and 8 is the time period during which you can eat. This is also defined as the fasting and feasting plan. You fast for 16 hours and the remaining 8 hours are the feasting period.

Now people who follow this regime argue that it is great for burning fat and building muscle. How do they get this idea?

When your body doesnt get the calories it needs, it ultimately starts burning off the body fat for energy. Theory has proven that you can lose weight by fasting for 1224 hours. Fasting also increases the insulin sensitivity of your body. It is believed that it stops your body from storing more fat. So theres scientific proof to put your mind at ease. Once the feasting period starts and you eat, the body can get the calories it needs to function properly.

Is Skipping Breakfast Bad For You The Surprising Truth

Breakfast is the most important meal of the day. This myth is pervasive in society.

Breakfast is perceived as healthy, even more important than other meals.

This seems like a problem, because up to 25% of Americans regularly skip breakfast .

However, new high-quality studies have started questioning the universal advice that everyone should eat breakfast.

This article takes a detailed look at breakfast, and whether skipping it is really going to harm your health and make you fat.

Short Fasts May Speed Up Your Metabolism

You may have heard that skipping meals will slow down your metabolism. But what about intermittent fasting?

Although starvation mode is a real thing, its not going to happen due to skipping a few meals.

In fact, one study found that during a 3 day extended fast, the study participants metabolism increased by a full 14% due to hormonal changes.

Your Body Becomes A Fat

Fasting works wonders on your metabolismyour fat metabolism, to be exact.

Similar to how the keto diet boosts fat-burning, fasting for 6 hours or longer increases your ability to burn fat. As with keto, the primary reason appears to be that you arent eating carbohydrates.

And when you regularly fast for extended periods, the effects become even more pronounced.

In other words, the longer and more often you fast, within reason, the better your bodys ability to burn fat becomes!

Can You Keep It Up

Calorie-controlled diets all have a similar impact on weight loss, but the diet that is really successful is one that people can sustain in the long-term.

One of the difficulties with sticking to a diet is craving forbidden foods, and with IF that is perhaps less of a problem.

“When I am on a no-carbohydrate or low carbohydrate diet all I see is pasta and rice everywhere, but now I don’t crave certain food groups because nothing is restricted,” says Shanae.

She has been following the 16:8 diet for four months now and finds it easier to keep up than the 5:2 diet, during which she gets very hungry.

“The hardest thing is to not reach for the breakfast muffin,” says Shanae.

Imahn Robertson, 26, has been following an IF diet for over four years.

“When I first started I did struggle, the body naturally craves foods at all times. But after I got into a routine it was okay,” says Imahn.

“There is temptation, don’t get me wrong. If I am tempted I will occasionally break my fast and adjust my fasting period the next day.”

However, Imahn admits that her diet has affected her social life.

“I only eat between 12 and 8pm – if someone schedules a dinner for nine o’clock, I will go to the dinner but just drink water.

“What makes it difficult is that people are very judgemental,” she says. “I find it easier to do intermittent fasting when I am single, not when I am in a relationship.”

What Are The Drawbacks Of Following The 1: 8 Diet

While the 16:8 diet seems like a great way to drop weight fast, it does have some cons. Sarah Mirkin, RD, author of Fill Your Plate, Lose the Weight, a 21-day meal plan designed to help women over 40 lose weight, says, “I think that it limits food intake to such a small window of time that it’s difficult for someone to meet their nutritional needs.”

Indeed, fasting for a long period of time probably means you’re not able to enjoy three full meals with snacks each day. Whether you’re skipping breakfast or dinner, missing a meal always results in not receiving adequate nutrients. And since the 16:8 diet gives you license to eat whatever you want, you might be tempted to fill up only on fatty, processed foods, especially if you’re feeling ravenous. Hunger can also clout your better judgment and lead you to binge eat as well. “Studies show that the majority of people are not able to sustain it for very long and oftentimes end up binging on unhealthy foods, causing weight gain,” Mirkin says. Other drawbacks of 16: 8 fasting include poor sleep, muscle mass loss , disordered/binge eating, weakness, nausea, and fatigue, Mirkin says.

Why Is Intermittent Fasting So Popular

Intermittent fasting is becoming an increasingly popular way to lose weight. What’s its appeal and is it safe to fast?

Whether it’s eating in a 5:2 or 16:8 pattern, losing weight is as much about when you eat as about what you eat these days.

Recently, Twitter CEO Jack Dorsey hit the headlines when he claimed to eat just one meal a day. Social media was abuzz, with many critics calling it an extreme diet. But perhaps he was just following the latest trend.

According to a survey by the International Food Information Council Foundation intermittent fasting was last year’s most popular diet.

Intermittent fasting can take many different forms but it always involves periods of time where you are taking in very little food, at regular intervals.

For a massive and aggressive weight loss, focus on low calorie diets and cardio exercises. If your aim is to shed some amount of kilos, then focus more on protein intake, try to eat more food compared to before and have at least 1000-1200 calories per day.

Intermittent Fasting can do wonders. I have already fasted for more than 5000 hours. But, try to include your hours of sleep in the fasting window. Also, try to start from 16:8 and drag it to a maximum of 22:2.

Include strength training to avoid loss of muscle mass and have green tea after your last meal. Add some saffron for more benefits.

How do I stay motivated?: There is no motivation. I feel driven to just complete the goal I have set for myself.

How do you ensure you dont lose focus?: I dont see that as an option. I have already struggled, suffered and been humiliated enough to let go of this.

Fasting Is About More Than Weight Loss

Samantha’s husband Kevin is also participating in the experiment, but he’s on the 5:2 diet.

Kevin must eat a healthy diet for five days but cut his kilojoules down to 2,500 on Tuesdays and Thursdays that’s less than a quarter of his regular intake.

Unlike Samantha, he starts to lose weight immediately.

“I managed to pull an extra notch on my belt for my pants, so that’s an inch down on my belt size,” he says.

“I’m happy to carry on.”

The research into the effectiveness of fasting diets “really is in the early days,” but Dr McMillan is hopeful that her experiment will show the benefits of fasting reach beyond weight loss.

“We’re so obsessed with weight in this culture, we talk about diet in terms of just weight loss. But is about what we eat and its impact on our whole body,” she says.

“What the research seems to show is that, at least in the short term, fasting is at least as effective as a traditional calorie-controlled weight-loss diet.

“But if we only look at fasting as a weight-loss trend, we demean the research we do have into fasting.”
