- May not lead to sustained weight loss or long-term improvement in health outcomes
- Not recommended for children, teens, pregnant or lactating women, or people with chronic health conditions
Healthy weight management comes with its benefits: less risk of diabetes, heart disease, joint issues and some cancers just to name a few. It is too soon to say that intermittent fasting is a reliable, long-term method for successful weight management as there are too many important questions that still require research to answer. However, initial results from studies are promising and should encourage future studies that examine the role of intermittent fasting in promoting weight loss and improved metabolic, neurological and cardiovascular health.

Gentle Foods To Break A Fast
When youre ready to break your fast, its best to ease out of it. Toward the end of your fast, you might want to introduce small portions of foods that are more easily digested, so you dont overwhelm your digestive system.
Breaking your fast with foods that are especially high in fat, sugar, or even fiber can be difficult for your body to digest, leading to bloating and discomfort.
Foods and drinks that can be even more shocking to your system after a fast include those like a greasy cheeseburger, slice of cake, or soda. Even high-fiber raw produce, nuts, and seeds may be difficult to digest.
On the other hand, nutrient-dense foods that easy to digest and contain a bit of protein and some healthy fats can break your fast more gently.
Below are a few examples of what to eat to break your fast.
Breaking your fast with healthy foods that may be better tolerated can help replenish important nutrients and electrolytes while easing food back into your diet.
Once youre tolerating gentler foods, add in other healthy foods like whole grains, beans, vegetables, nuts, seeds, meat, poultry, and fish and return to eating normally.
Be Mindful Not To Overeat
It can be easy to overeat between fasting periods.
Although fasting doesnt emphasize what you eat as much as when you eat, its not designed to be an excuse to eat unhealthy foods.
Overeating and eating junk food between fasting periods can cancel out the health benefits of fasting. Instead, choose minimally processed, whole foods as much as possible for the most overall health benefits.
When youre ready to break your fast, start with foods and drinks that will be gentle on your digestive system. Avoid foods that are especially high in sugar, fat, and fiber. Additionally, take care not to overeat.

For instance, fiber is a carbohydrate that aids in digestion, helps you feel full, and keeps blood cholesterol levels in check.
Carbs often get a bad reputation for causing weight gain. Not all carbs are created equal and they are not inherently fattening. You should choose foods that are high in fiber and starch but low in sugars.
Healthy carbohydrate-rich foods include:

Why Do Intermittent Fasting Then
So if fasting per se isnt what results in weight loss and health improvements, why then do intermittent fasting in the first place?
Well, although fasting doesnt seem to have any magical properties in and of itself, there are a number of good reasons why you should consider doing intermittent fasting! This is, after all, why we often use this approach with many of our online fitness coaching clients!
So here are a few reasons why you should consider doing intermittent fasting :
1. More structured eating
How often have you found yourself mindlessly snacking between meals? A couple of cookies with your coffee, a small piece of cake that Suzy brought for her birthday at work, a few nuts and dried fruits before dinner, some popcorn with a movie at night. When you think about it, little snacks here and there can add up to quite a few calories. Well, the more structured eating that is a result of intermittent fasting can eliminate this problem and can help people better control their diet.
2. Bigger, more satisfying meals
Eating every 2-3 hours sucks. For one, its impractical and makes you think of food all day. It also means that you never really get to eat big meals, especially if you are a smaller, physically inactive person. On the other hand, more infrequent meals that are larger in volume and provide more calories are usually much more satisfying and may help you feel fuller for longer.
3. Sustainability and adherence
4. Social Flexibility
5. Improved hunger awareness
Diet Plan: What Can You Eat And What Are The Benefits
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.

Break Your Fast With Modestly
Breaking your fast by bingeing on large portions of junk foods will turn out to be counter-productive. When you’re fasting for 12 to 14 hours, you are likely to be ravenous when the fasting window ends. But overcome your instinct to eat lots of food and instead break your fast with a modestly-sized and healthy meal.

It May Aid Weight Loss
Various methods of intermittent fasting, including 20-hour fasting cycles, have been linked to weight loss.
One study, which closely mimicked the Warrior Diet , found that people who consumed meals over four hours in the evening experienced more weight loss than those who consumed the same amount of calories in meals throughout the day.
Whats more, those who ate one meal per day showed significantly reduced fat mass and greater muscle mass .
A recent review of six studies concluded that various types of intermittent fasting, ranging from 3 to 12 months, were more effective at promoting weight loss than no dietary intervention.
However, the review found that there were no significant weight loss differences between dieters using intermittent fasting or continuous calorie restriction , meaning that calorie restriction without fasting was equally effective .
Additionally, although reducing calorie intake is the most common outcome of the Warrior Diet, some people following this eating pattern could technically consume too many calories during the four-hour overeating period and experience weight gain.

How Does The 1: 8 Diet Work
The 16:8 diet works on an hourly basis. So each day you can eat within an 8 hour time frame and fast for the remaining 16 hours. The best part? You dont have to restrict your calories when eating during the 8 hour window. As long as you eat healthily in your 8 hour time frame, youll see the weight drop off.
Experts say that the 16.8 diet restricted schedule gives our bodies the chance to process the nutrients stored in foods and burns away calories. Plus, you wont go hungry like you do on those two fasting days on the 5:2 either.
As Tom Jenane, nutrition and fitness expert explains, The 16:8 diet is a brilliant form of intermittent fasting that has proven results in a number of cases.
Jennifer Aniston is a famous fan of intermittent fasting.
As well as Jennifer Aniston, other Hollywood names who have seen success after following the 16:8 diet include Hugh Jackman, who reportedly used the diet to get in shape for his Wolverine films and actress Jennifer Love Hewitt.
I Would Move Away From Intermittent Fasting For Fat Loss And If You Want To Adopt It Think About The Health Benefits Rachel Clarkson
Someone who has a high-carb diet might never move beyond the catabolic state as they will always have a reserve supply of glycogen. However, someone with a low-carb diet and who regularly exercises might move through it very quickly . I would move away from intermittent fasting for fat loss, and if you want to adopt it think about the health benefits, says Clarkson.
How to fast
To fast you have to downregulate the feeling of hunger, says Clarkson. Hunger is felt when ghrelin, a hormone released from our stomach, triggers the production of two other hormones, called NPY and AgRP, in the hypothalamus.
While these three hormones generate feelings of hunger, there are a multitude more that suppress it. Sometimes called the satiety hormones, one of the key ones is leptin which is released from fat cells to suppress the production of ghrelin basically telling the body “there is fat here that you can burn”.
Ghrelin is sometimes called the short-term hunger response because it is released when the stomach is empty and there is less pressure on the stomach wall. It can be overridden to a certain extent by drinking water. Leptin meanwhile works over the long term.

Does Intermittent Fasting Boost Your Metabolism
Intermittent fasting is an eating pattern that involves periods of food restriction, called fasting, followed by a period of regular eating.
This pattern of eating could help you lose weight, reduce your risk of disease, and increase your lifespan .
Some experts even claim that its beneficial effects on metabolism make it a healthier way to lose weight than standard calorie restriction (
Studies have shown that when it comes to weight loss, intermittent fasting can be just as effective as traditional calorie restriction, if not more so .
In fact, a 2014 review found that intermittent fasting could help people lose an impressive 38% of their body weight in 324 weeks .
A 2016 review concluded that in people who have obesity or overweight, intermittent fasting may be a better approach to weight loss than very low calorie diets (

You Sabotage With Soda
Mills says the carbonation in soda can mask your sense of hunger, which can set you up for being too hungry at your next meal and lead you to overeat. “Artificially sweetened drinks can also raise the satisfaction bar for sweet tastes, so when you do eat a piece of fruit it may not be satisfying.”
She adds these beverages may also have caffeine, which can affect people differently. “Some caffeine may make you jittery and set you up for craving sweets. While other caffeine may mask your sense of hunger and postpone eating until well past feeling hungry.”

What To Drink While Intermittent Fasting
So, what are you allowed to drink when youre fasting? The goal is to choose beverages that are calorie-free, says registered dietitian Colleen Tewksbury, PhD, MPH, RDN, CSOWM, LDN, a national spokesperson for the Academy of Nutrition and Dietetics.
Water is always a great choice: tap water, bottled water, sparkling water, even flavored water, as long as its calorie-free.
I always recommend staying adequately hydrated with water while intermittent fasting, as dehydration combined with low food intake is a recipe for feeling downright exhausted, says Sheri Vettel, RD, a registered dietitian at the Institute for Integrative Nutrition.
Other possible choices:
- Coffee. Go with black coffee or add a little calorie-free sweetener.
- Tea. Again, forego the spoonfuls of sugar.
- Diet soda. Read the label to make sure its calorie-free, and not just low-cal.
If the idea of unsweetened drinks makes you despair, you could try a non-nutritive sweetener like stevia or xylitol. But xylitol can upset your stomach, so you might want to go easy on it, especially at first.
It does sweeten quite nicely, says Stanford. But it can cause significant GI upset if you take too high a quantity of it.
Some experts do suggest steering clear of diet soda or other drinks that contain artificial sweeteners. But Stanford notes that unless youre consuming really large amounts of sweetener all the time, its probably okay.
Everything in moderation is where I stand, says Stanford.
