The Fasting Mimicking Diet Do
Anne put together four great DIY hacks for a fasting mimicking diet, but the Foodzie team recently agreed we want to do more for our readers. So here is our five-day, total DIY fasting mimicking diet plan.
A few notes first:
What Is A Fasting Mimicking Diet
Fast mimicking is a type of modified fasting. Instead of abstaining from food completely like a traditional fast, you consume small amounts of food but you do it in a way that gives you the benefits of fasting.
A fast-mimicking diet typically lasts about five days youll keep your carb, protein, and calorie intake low and your fat intake high. Calories are kept at around 40% of normal intake. This keeps you nourished with nutrients and electrolytes. It also puts less stress on your body than normal fasting while still giving you the same benefits.
Long-term calorie restriction and long-term fasting can harmful, but fast mimicking is safer and more effective. First, look at how much it differs from traditional fasting.
When Can I Eat On The 1: 8 Diet
If you’re following the 16:8 diet, you can pick any 8-hour window to suit your day. “The most common hours adopted for the eating period is 12pm to 8pm,” explains Tom Jenane, nutrition and fitness expert at Nature’s Health Box . “The reason for this is because people aren’t normally that hungry in the morning and you don’t want to be consuming too many calories in the evening. This window allows for lunch and dinner as well as healthy snacks .”
But while the choice is yours when it comes to eating on the 16:8 diet, research has identified the best time to eat breakfast, lunch and dinner for weight loss. According to a study by University of Murcia , it’s best to stick to a breakfast in the morning as skipping the meal is linked to a higher rate of obesity. While a late lunch can hinder weight loss in those trying to reduce fat mass. And a late dinner decreases glucose tolerance, making it easier to gain weight.

Eat Plenty Of Whole Foods On Non
Most people who fast are trying to improve their health.
Even though fasting involves abstaining from food, its still important to maintain a healthy lifestyle on days when you are not fasting.
You can make sure your diet remains healthy by choosing whole foods like meat, fish, eggs, vegetables, fruits and legumes when you eat.
Summary Eating whole foods when you arent fasting may improve your health and keep you well during a fast.
When Should I Exercise
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.
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.

The 16:8 diet plan is one of the most popular ways to get into intermittent fasting, with big names like Jennifer Aniston and Hugh Jackman swearing by their successes.
It’s not only celebrity endorsement that has got this eating regime its reputation though. While not as restrictive as the 5:2 diet plan, clinical nutritionist Suzie Sawyer says, the 16:8 still prolongs “the period when your body has burned through calories consumed during your last meal and begins burning fat.” In other words, it helps participants lose weight by reducing the amount of time they have available to eat – and so putting them into an energy deficit, which in turn helps them to lose weight.
All of this without the need to count calories or spend hours on a treadmill. But is the plan all it’s really cracked up to be?
Prolonged Fasting For 3
This involves going with no calories for 3-5 days. These types of fasts are usually done under medical supervision. All studies of prolonged fasting allow up to 500 calories during fasting days. These calories should come from low-protein, low-carb foods. This usually means vegetable juices and vegetable soup, averaging a total calorie intake of 200250 kcal and 2535 g of carbohydrates per day. Our CEO does quarterly 5-day modified fasts in which he eats 2 cups of mixed greens with olive oil and a handful of almonds for a total of 250 calories.
Do not attempt a multi-day fast with water only. All clinical trials of multi-day fasts involve at least minimal calorie and micronutrient intake.

Youll Likely Feel Hungry
Even an 8- or 12-hour fast might feel like a long time when youre not used to fasting.
You may go to bed hungry several times per week. That may naturally feel unpleasant and unsustainable in the long term .
Plus, at times, it might be necessary to override your natural hunger and fullness cues in order to not break your fast earlier than planned.
This doesnt mean that fasting isnt a schedule you can get used to. Once youve adjusted to intermittent fasting, you might even find it makes you feel less hungry (
How Much Does Prolon Cost
The ProLon meal kit costs between $225 $249 depending upon how many meal kits you buy at one time. If you buy 1-2 boxes, you pay $249 per box. If you order 3 or more boxes, you pay $225 per box. There is also an option to get subscribe to an auto-ship for $225 per box.
If you break it down by day, your cost is about $50 per day.
That is a bit steep, but since this lasts only 5 days and is to be done only once every 6 months it could be a good option.
For those who like the idea but want to do this with food from the grocery store, Ill outline a do-it-yourself version.

Can Be A Sustainable Lifestyle Change
Intermittent fasting might sound complicated and intimidating, but it can be simple at times. In fact, you might even find that fasting helps simplify your day since you need to plan fewer meals.
Whats more, it doesnt typically require calorie counting, watching your macros, eating certain foods that you might not be used to eating, or eliminating certain foods that you otherwise enjoy.
For example, having an early dinner followed by a late breakfast the next day is one way to fast intermittently. If you finish your last meal at 8 p.m. and dont eat until noon the next day, youve technically fasted for 16 hours.
For people who get hungry in the morning and like to eat breakfast, or for those who cant eat until later in the evening due to work schedules and other obligations, this method may be hard to get used to.
However, other people instinctively eat this way already. They may be more prone to trying out an intermittent fasting eating pattern.
Ending A Longer Fast: A Quiet Gut Revs Up Again
Longer-term fasts are different. Resuming eating after a longer fast takes more planning and care.
As we start to incorporate fasting into our routines, our bodies physiologically take a bit of time to adjust to the new regimen, especially if we used to eat constantly. As chronic eaters, our bodies are constantly spending metabolic energy producing digestive enzymes to process the food were consuming. This changes when we first start fasting. The digestive enzymes are not needed or produced.1

Some General Safety Tips
- Drink water when you are thirsty.
- Adjust your caloric intake during your feeding windows so that you consume enough calories to meet your energy needs according to your weight goals.
- If you feel faint, dizzy or nauseous, we recommend breaking your fast early and speaking with your primary care physician. You may have symptoms of low blood sugar or another issue.
- Talk to your physician before upping your fasting window beyond 18 hours per day.
- Break your fast with low glycemic index foods, such as lean protein and healthy fats like avocados
- Never do fasts longer than 2 days by yourself. Always tell someone, a family member or friend and keep them updated on how you are feeling as you progress.
- During fasts longer than 2 days, watch for signs of electrolyte imbalance: muscle spasms, weakness, blood pressure changes, irregular heartbeat, numbness and confusion.
What Is 16/8 Intermittent Fasting
The practice of 16/8 intermittent fasting involves limiting your intake of foods and calorie-containing beverages to a set window of 8 hours per day. You abstain from food for the remaining 16 hours, though youre still allowed to drink water and other no-calorie beverages, like plain coffee or tea.
You can repeat this cycle as frequently as youd like from just once or twice per week to every day, depending on your preference.
The popularity of this fasting method has grown widely among those looking to lose weight and burn fat. 16/8 intermittent fasting is also believed to improve blood sugar control and enhance longevity.
While other diets often set strict rules, 16/8 intermittent fasting is easy to follow and may provide measurable results with minimal disruption to your diet. Its generally considered less restrictive and more flexible than many other diets and works with most lifestyles.
With 16/8 intermittent fasting, you restrict your food intake to an 8-hour window and fast for the remaining 16 hours. This practice may support weight loss, improve blood sugar, and increase longevity.
It is simple, safe, and sustainable to do 16/8 intermittent fasting.

Save Even More Money On A Fasting Mimicking Diet
The fasting mimicking menus here were designed to create some variety, because fasting is hard enough as it is. But if you want to save even more money, simply repeat soups and snacks.
A box of Imagine Organic soup, for example, has at least two or three FMD meals in it. So if you can handle the same soup for two days, youll save some money. Similarly, one small tub of hummus and one cucumber can be a 75 calorie snack a few times, one box of tea is cheaper than three, etc.
Proposed Health Benefits Of Intermittent Fasting
When it comes to weight loss, there are two thoughts behind why IF has the potential to work. The first: Periods of fasting produce a net calorie deficit, so you lose weight, explains Rekha Kumar, MD, a specialist in endocrinology, diabetes, and metabolism at the Comprehensive Weight Control Center at Weill Cornell Medicine and NewYorkPresbyterian in New York City.
The other concept is more complex: This approach may prevent whats called the plateau phenomenon from happening, Dr. Kumar says.
Though more research is needed on the safety and effectiveness of IF, one of the touted benefits of this approach is that it may prevent this metabolic sputtering. Most people who try diet and exercise to lose weight tend to fall off the wagon and regain weight, Kumar says. Hormones that promote weight regain, like hunger hormones, are kicked into full gear, and the thought is that IF may be a way to prevent this metabolic adaptation from happening. The idea is that the normal periods of eating in IF trick your body into losing weight before the plateau happens.

Level Of Effort: Hard
Limitations: Itâs not easy to skip most of your calories a few days a week and rely mostly on water, coffee, and tea to keep you feeling full. Youâll need a balanced meal plan to eat in moderation on your so-called “feast” days, despite their name. You can indulge in a treat occasionally, but that’s about it if you want to see results.
Cooking and shopping: You can continue your regular cooking and shopping, as long as you stick to mostly healthy foods.
Packaged food and meals? No.
In-person meetings: No.
Exercise: How much you exercise is up to you. But obviously, youâre not going to have a lot of energy for that on your fasting days. The creators of the Every Other Day diet studied people doing cardiovascular exercise while on the alternate-day fasting plan and found that they were able to maintain muscle mass while fasting.
What’s The Evidence From Human Studies Of Calorie Restriction
Some study results suggest that calorie restriction may have health benefits for humans, but more research is needed before we understand its long-term effects. There are no data in humans on the relationship between calorie restriction and longevity.
Some people have voluntarily practiced extreme degrees of calorie restriction over many years in the belief that it will extend lifespan or preserve health. Studies on these individuals have found markedly low levels of risk factors for cardiovascular disease and diabetes. The studies have also found many other physiologic effects whose long-term benefits and risks are uncertain, as well as reductions in sexual interest and the ability to maintain body temperature in cold environments. These people generally consume a variety of nutritional supplements, which limits knowing which effects are due to calorie restriction versus other factors.
To conduct a more rigorous study of calorie restriction in humans, NIA supported a pioneering clinical trial called Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy .
In CALERIE, 218 young and middle-aged, normal-weight or moderately overweight adults were randomly divided into two groups. People in the experimental group were told to follow a calorie-restriction diet for 2 years, while those in the control group followed their usual diet.

What’s The Evidence From Human Studies Of Fasting
Most research to date has focused on the weight-loss aspect of fasting, primarily in obese people, and only a few small clinical trials have been conducted. More work is needed to determine which, if any, types of fasting diets have long-term benefits.
Observational studies have been conducted in people who practice fasting in one form or another. In an observational study, the investigator does not determine the treatment to offer and does not randomize subjects into a control group or experimental group. Instead, the investigator records data from real-life situations.
For example, one observational study compared people who routinely fasted to those who did not fast. It found that those who routinely fasted were less likely to have clogged arteries or coronary artery disease. However, the study did not control for other factors that could have affected the results, such as the kind of diet, quality of food consumed, or use of nutritional supplements.
How Does Intermittent Fasting Work
There are several different ways to do intermittent fasting, but they are all based on choosing regular time periods to eat and fast. For instance, you might try eating only during an eight-hour period each day and fast for the remainder. Or you might choose to eat only one meal a day two days a week. There are many different intermittent fasting schedules.
Mattson says that after hours without food, the body exhausts its sugar stores and starts burning fat. He refers to this as metabolic switching.
Intermittent fasting contrasts with the normal eating pattern for most Americans, who eat throughout their waking hours, Mattson says. If someone is eating three meals a day, plus snacks, and theyre not exercising, then every time they eat, theyre running on those calories and not burning their fat stores.
Intermittent fasting works by prolonging the period when your body has burned through the calories consumed during your last meal and begins burning fat.
