Choose Your Best Protocol
Krystal began her intermittent fasting journey about a year ago, and she experimented with various protocols until she found the right protocol.
I alternate what kind of fasting I do. Sometimes I stick with a traditional 16:8 fasting period, other times I will do a longer time frame, she says. My longest fast was five days.
Though five days might seem a bit overwhelming to a beginner, Krystal urges readers to find whats best for them. For her journey, Krystal admits, I read a lot about the health benefits of fasting, plus with following a ketogenic diet fasting came naturally as my hunger levels decreased.
What Are The Benefits Of Intermittent Fasting
Heres what the science says about the ways IF might help you get healthier.
One study with 150 participants for 50 weeks showed IF to be as effective as a diet that restricts calories other small studies have shown that IF will help you lose weight in the short-term. A review of 27 trials found that weight loss from .8 percent to 13 percent of baseline body weight occurred with IF, though the researchers pointed out that larger studies of longer duration are needed. In 16 of the studies that measured BMI, the participants BMI decreased by 4.3 percent, says Kelly. Reducing the daily eating window may also decrease caloric intake for the whole day, resulting in weight loss without restrictive calorie counting.
Chronic inflammation is associated with a long list of health conditions, including dementia, diabetes, stroke, and heart disease, says Cohen. While mice studies have demonstrated that short periods of fasting show a reduction in inflammatory markers, a small human study showed IF reduced the levels of pro-inflammatory factors such as homocysteine and C reactive protein, which contribute to the development of plaque in the arteries. Another small eight-week study in overweight patients showed an improvement of asthma symptoms including better pulmonary function.
The Different Forms Of Intermittent Fasting
There are different approaches to intermittent fasting:
- Fast Five With this model, you can eat 5 hours a day and fast for the remaining 19 hours. The food window here would be between 1pm and 6pm, for example, but it is freely selectable.
- Warrior diet: this form adheres to a strict 20: 4 rhythm. Here you can only eat four hours a day, the rest of the time it is fasting.
- Leangains Fast for 16 hours and eat for 8 hours The 16: 8 method is easy to implement, especially for workers, and is particularly popular with athletes.
- Eat Stop Eat: Fast for 24 hours, quite difficult. With Brad Pilons Methoe, you can only eat once a day, but you only have to eat it once or twice a week.
- Alternate Day Fasting: Eat for 24 hours, Fast for 24 hours, and Start Over: With the ADF method, fasting is done every other day.
In general, of course, the following applies: For the elderly success achieve is sports useful fast food, on the other hand, probably not. Its best if you prepare your meals as healthy as possible in the food window. You can find tips for this here:

How To Fast For Weight Loss
Weight loss studies of intermittent fasting have typically investigated the 5:2 diet or alternate day fasting interventions lasting three to six months. For most people in such studies, it takes two to three months to lose 10 pounds.
The good news is that most studies of intermittent fasting using the 5:2 diet protocol or minimal calorie fasting days have reported statistically significant weight loss, approximately equivalent to what can be achieved through continuous calorie restriction. Reported weight loss outcomes of the 5:2 diet range from 3.2% weight loss in comparison to a control group over a 12-week period to 8.0% weight loss in an 8-week trial enrolling overweight adults with asthma.
Obese adults who participated on an alternate day fasting study for 6 months lost roughly 6% of their body weight during the first 3 months. They were allowed to consume up to 600 kcal on their fasting days and ate a low-carb diet on non-fasting days. In addition to losing weight, participants were also able to reduce their total cholesterol, blood pressure, and fasting insulin.
Shorter fasts are also effective at inducing weight loss in humans. Obese patients who restricted their eating windows to 8 hours lost significant weight and improved their blood pressure.
How To Stay Focused
With so many resources pertaining to intermittent fasting, not all the information you find online can be trusted. Poorly informed or false sources can give IF a bad rep, which Krystal felt firsthand.
The biggest challenge is probably other peoples perceptions of fasting and overcoming the idea that not eating is dangerous or an eating disorder, said Krystal. Ive found that having information about why I do what I do helps me stay focused.

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.
Examples Of Different Intermittent Fasting Schedules
If youre considering giving fasting a shot, there are a few different options for working it into your lifestyle.
Daily Intermittent Fasting
Most of the time, I follow the Leangains model of intermittent fasting, which uses a 16hour fast followed by an 8hour eating period. This model of daily intermittent fasting was popularized by Martin Berkhan of Leangains.com, which is where the name originated.
It doesn’t matter when you start your 8hour eating period. You can start at 8am and stop at 4pm. Or you start at 2pm and stop at 10pm. Do whatever works for you. I tend to find that eating around 1pm and 8pm works well because those times allow me to eat lunch and dinner with friends and family. Breakfast is typically a meal that I eat on my own, so skipping it isn’t a big deal.
Because daily intermittent fasting is done every day it becomes very easy to get into the habit of eating on this schedule. Right now, you’re probably eating around the same time every day without thinking about it. Well, with daily intermittent fasting it’s the same thing, you just learn to not eat at certain times, which is remarkably easy.
Weekly Intermittent Fasting
One of the best ways to get started with intermittent fasting is to do it once per week or once per month. The occasional fast has been shown to lead to many of the benefits of fasting we’ve already talked about, so even if you don’t use it to cut down on calories consistently there are still many other health benefits of fasting.

What To Eat With Fasting
Ive found most people who have trouble with their weight do better eating a lower amount of carbs. Im not saying you have to cut them out completely but you should focus on lowering them to boost weight loss. People who are naturally athletic and have more trouble putting on weight do better with lower fats and higher carbs and protein.
You should calculate your BMR to give you a ballpark picture of how many calories your body burns in a day. Then you should keep your calories under that number. You dont have to count your calories for the rest of your life but you should do so for at least for a little while so you can figure out what you should be eating in a day.
Focus on eating real whole foods. Higher protein diets have also been found to be beneficial for weight loss. Avoid starchy, sugary, and carb-rich foods especially those from refined grains and flour. Lastly, make sure youre avoiding bad vegetable oils that could also promote weight gain.
Should you exercise during fasting?
When it comes to exercise youll drop more poundage by working out along with your fasting . I prefer to do cardio in the mornings when Im fasting for an extra fat burn . Then doing a strength training workout later in the day can help to tone up and burn stubborn fat from your body.

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.

Alternate Day Fasting : 2 Method
Some people fast on alternate days to improve blood sugar, cholesterol, and weight loss. A person on the 5:2 method eats 500 to 600 calories on two non-consecutive days each week.
Some alternate-day fasting regimens add in a third day of fasting each week. For the rest of the week, a person eats only the number of calories they burn during the day. Over time, this creates a calorie deficit that allows the person to lose weight.

The 16:8 diet has been one of the most popular diet plans weve seen in years and with good reason.
The 16:8 plan also called the 8-hour diet is an easier and more consistent way of fasting that avoids heavily calorie restricted days found in other popular intermittent fasting plans like the 5:2 diet or Fast 800 calorie diet.
A famous fan of the 16:8 intermittent fasting plan is Hollywood icon Jennifer Aniston. In an interview with the Radio Times, Jennifer revealed that shes a big fan of intermittent fasting in general but specifically this plan. I do intermittent fasting, so no food in the morning. She said, I noticed a big difference in going without solid food for 16 hours.

Benefits Of A Whole Food Diet
In a 2014 analysis by Yale University, they concluded that a diet of minimally processed foods close to nature, predominantly plants, is decisively associated with health promotion and disease prevention.
A diet rich in fruit and vegetables or other high-fiber foods like whole grains and nuts is really important in maintaining good long-term health and preventing health problems like diabetes and cancers. These kinds of foods also help our bodies to cope and control the effects of inflammation.
In fact, one review from 2019 stated that diets high in plant foods could potentially prevent several million premature deaths each year if adopted globally. This is a big endorsement for a whole food diet.
Whether You Have Preexisting Medical Conditions
When you go to the doctor, do you get a clean bill of health? If so, then your body wont impede your weight loss efforts provided youre trying to slim down healthily. Should you have any preexisting medical conditions though, they can affect how easy it is for you to lose weight.
We mentioned before that those with type 2 diabetes might lose weight more slowly than non-diabetics. If you have polycystic ovary syndrome or PCOS, keeping the weight off can be difficult. Thats also true of those with Cushings syndrome and hypothyroidism.
Living with chronic stress floods your body with cortisol that can cause you to retain abdominal fat. Your blood pressure can also go up and your immune system might be less effective.
Some medical conditions make you lose more weight than intended, such as endocarditis, depression, and rheumatoid arthritis. That said, this weight loss is often not healthy, so you should speak to your doctor before you start keto or intermittent fasting.

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.
