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, research has identified the best time to eat breakfast, lunch and dinner for weight loss. According to a study by the 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. Meanwhile, 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.

Meal Day My Method Of Intermittent Fasting
I created the 2 Meal Day because focusing on eating windows can cause issues.
For me, the benefits of intermittent fasting come from learning to listen to your body.
When you focus on the clock, you dont learn to listen to your body.
You eat because the clock tells you to.
This can mean that fasting doesnt become a way of life.
The 2 Meal Day isnt complicated.
Drop one meal, either breakfast or dinner.
Learn to eat when you are hungry.
Your fasting window will change daily between 12-20 hours.
Its the best way to learn to be flexible in your approach and get long-term success.
I have spent years experimenting and trying out every intermittent fasting windows.
I have helped 1000s of other people incorporate it as a way of life.
Most people choose to skip breakfast and have a large, satisfying lunch and dinner.
For the particularly active, an optional snack in between those two meals works well.

May Improve Blood Sugar Levels
Intermittent fasting is generally associated with improving blood sugar control and insulin sensitivity . A pilot study done in 2017 showed that fasting for 18 to 20 hours a day could lead to weight loss and post-meal blood sugar control . This shows that fasting could be extremely beneficial to patients with type 2 diabetes. However, if you are suffering from this disease, please talk to your doctor before trying the 20-hour fast, or any other form of intermittent fasting.

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.
Intermittent Fasting May Affect Men And Women Differently
There is some evidence that intermittent fasting may not be as beneficial for some women as it is for men.
One study showed that blood sugar control actually worsened in women after three weeks of intermittent fasting, which was not the case in men .
There are also many anecdotal stories of women who have experienced changes to their menstrual cycles after starting intermittent fasting.
Such shifts occur because female bodies are extremely sensitive to calorie restriction.
When calorie intake is low such as from fasting for too long or too frequently a small part of the brain called the hypothalamus is affected.
This can disrupt the secretion of gonadotropin-releasing hormone , a hormone that helps release two reproductive hormones: luteinizing hormone and follicle stimulating hormone (
10 ).
For these reasons, women should consider a modified approach to intermittent fasting, such as shorter fasting periods and fewer fasting days.
Summary
Intermittent fasting may not be as beneficial for women as it is for men. To reduce any adverse effects, women should take a mild approach to fasting: shorter fasts and fewer fasting days.
Intermittent fasting not only benefits your waistline but may also lower your risk of developing a number of chronic diseases.

Intermittent Fasting: Is It Right For You
U-M dietitian Sue Ryskamp weighs in on intermittent fasting benefits, who it works best for and how to get started
Weight loss can be difficult, but could intermittent fasting help? This eating pattern, which features cycles of fasting and eating, is making headlines as research confirms its not only what you eat, but when you eat, that matters in the struggle to lose weight.
During intermittent fasting, individuals use specific periods of eating typically within an eight-to-10 hour window to lose weight, says Michigan Medicine dietitian Sue Ryskamp, who sees patients at U-Ms Frankel Cardiovascular Center.
The premise behind intermittent fasting is relatively simple, she says: When our insulin levels go down far enough and for long enough, as they do during a fasting period, were able burn off fat.
Insulin levels drop when a person is not consuming food. During a period of fasting, decreasing insulin levels cause cells to release stored glucose as energy. Repeating this process regularly, as with intermittent fasting, leads to weight loss. In addition, this type of fasting often results in the consumption of fewer calories overall, which contributes to weight loss, Ryskamp says.
A Harvard research study also reveals how intermittent fasting may slow the aging process through weight loss, lower blood pressure and reduced cholesterol.
All Kinds Of Vegetables
A diet rich in vegetables and fruits can help lower blood pressure, reduce the risk of heart disease and stroke, prevent some types of cancer, lower the risk of eye and digestive problems, and positively affect blood sugar levels, which can help keep appetite in check .
There are starchy and non-starchy vegetables:

How Can Intermittent Fasting Help With Weight Loss
Intermittent fasting can be effective in reducing body weight in people of every size, according to a report in Nutrition Reviews . Most studies focused on alternate day fasting or whole-day fasting trials, but there is also evidence to support the success of time-restricted eating. As well as weight loss, intermittent fasting can have cardiometabolic benefits for those with obesity, as found in another review in the 2021 Annual Review of Nutrition .
Similar to the way the keto diet helps with weight loss, intermittent fasting can put you into a state called ketosis where you are using ketones as fuel. A study in the journal of Cell Metabolism indicates that in the state of ketosis, the body metabolizes fat and produces ketones, which the body can use as an alternative energy source.
After a meal, you pass through four different metabolic states as your body digests the food, explains Dr Deborah Lee, MD, from Dr Fox Online Pharmacy . These are: the fed state, the post-absorptive state/early fasting state, the late fasting state, and starvation.
Having worked for many years in the U.K’s National Health Service, initially as a GP, and then as Lead Clinician for an integrated Community Sexual Health Service, Dr Deborah Lee now works as a health and medical writer, with an emphasis on womens health. She is a menopause specialist.

What Are The Side Effects Of Intermittent Fasting
When some people think about intermittent fasting, they worry theyll be hungry and grumpy all the time. For some people, that may be true for the first couple of days. But your body adjusts quickly as long as you dont give in to those initial hunger pangs.
On the positive side, people often report having better focus and mental clarity after they start intermittent fasting. This is because when youre in a fasting state, your body breaks down stored fat into ketones to use as fuel. The brain actually operates better when its fueled by ketones instead of sugar. Studies have shown potential long-term benefits for the brain as well, such as a .
As I mentioned above, intermittent fasting also causes your body to become more sensitive to insulin. In fact, a commitment to intermittent fasting can reverse the effects of prediabetes and help you avoid type 2 diabetes.
Intermittent fasting can also help with weight loss. Most Americans could stand to lose a few pounds, so this is great news for most of us. However, if youre not trying to lose weight or if youre underweight, talk with a dietitian to determine a healthy intermittent fasting plan for your body and goals.
So Which Intermittent Fasting Schedule Is Best For Weight Loss Whichever One You’ll Actually Stick To Tbh
In short, the one that’s easiest for you to follow. “It is all about sustainability for the individual,” says Amanda Baker Lemein, RD, a WH advisor. “If one of these diets work well for you and your lifestyle and preferences, then you will likely see some success. If not, then you’ll likely not see the results you’re are looking for, as the sustainability piece will not be there.” That means picking a diet that work best with all the lifestyle factors you need to consider, like your work schedule, family dynamic, living situation, commute time, and travel commitments, notes Lemein.

It’s worth pointing out, though, that the 16:8 diet seems to be the most doable for a lot of people who are into IF. The 16:8 method also scores points for preventing overeating at night, which can often be a big obstacle for weight loss. And sticking to an eight-hour eating window during daylight hours allows your metabolism to run as its supposed toyou fuel up for energy during the day , and stop eating for rest and recovery at night, per a 2017 article in the journal Nutrition Reviews.
The bottom line: All intermittent fasting schedules may lead to weight loss if you can follow them sustainably, and the 14:10 method may be the easiest way to follow an IF diet.

Most research has been conducted in animals, and human bodies don’t 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 isn’t 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.

In addition to fluid loss, a second significant aspect is responsible for physical complaints such as dizziness.
An undersupply of salt is the primary trigger for this. Therefore, even in strict therapeutic fasting, natural salt is allowed in addition to water.
Besides other electrolytes, sodium, in particular, is flushed out of the body while breaking down carbohydrate stores. Since salt has an unjustly unhealthy image, nutrition-conscious people often save with it.
However, we now know that those countries with the highest salt consumption have the lowest rates of cardiovascular disease .
Moreover, salt takes the bitter taste out of food and acts against cravings. Since it also has a negative feedback loop, unlike sugar, your body will tell you when youve had enough salt.
While sugar consumption promotes insulin resistance and body fat storage, salt increases insulin sensitivity and aids weight loss .
Finally, salt is the natural antagonist of sugar. If you want intermittent fasting without problems, salt your food as you like.
Furthermore, if you have a headache during fasting, you can dissolve natural Himalayan salt in water or drink homemade sole water.

The Difference Between Short And Long Fasts
Every night when we stop eating and then go to bed, we go through a short-term fast until our first meal of the next day. Depending on when you ate dinner and when you consume your first meal after you wake up, you can easily go through a 12 to 16-hour fast with no physiologic change to digestive functions.
Although there is no clear consensus or accepted definition about what the cut off is between a short and a long-term fast, Diet Doctor defines anything less than 24 hours as time-restricted eating, fasts between 24 and 36 hours as a short-term fast, and anything longer than 36 hours a long-term fast.
Time-restricted eating and short-term fasts dont require specific precautions when breaking the fast. Just remember it is a good idea not to binge on highly-processed, sugary, or high-carb foods because you will undo the advantages of the fast. Plan to eat a wholesome, low-carb, high-fat meal, such as any of the meals featured in the Diet Doctor recipes, and you will be just fine.

Zane doesnt pull any punches on the topic of intermittent fasting cheat days: Im not even sure what the point is.
A cheat day is equivalent to a binge day for most people, but the effects of the binge dont disappear after 24 hours. It can take three or four days to recover from the effects of a cheat day, reign in your cravings, regain your energy and focus, and get back on track.
If your goal is weight loss and youre trying to get somewhere effectively, why throw it all off with an entire meal of something like pizza or a bunch of pancakes? Zane asks. A surge of 1,500 calories of junk during an intermittent fasting cheat day will drive you in the opposite direction of your goals.

Choose The Right Fasting Style For You
An Obesity Society study found alternate day fasting can cause an impaired glucose response in women with a healthy body weight, so this may not the best fasting style for women. Mor agrees that women may need to be more careful with intermittent fasting than men. More studies are needed to understand the impact of intermittent fasting on women in particular. There has been some evidence that men can benefit from intermittent fasting, while women may be negatively affected.
Intermittent fasting may be easier in terms of fitting around a typical working day, where you are busy during the day which takes your mind off not eating,” says Dr Lee. “With any diet, but perhaps especially calorie restriction, you need to plan your meals and prepare them in advance. You can also work intermittent fasting around your social life more easily perhaps, making sure you only accept invitations on non-fasting days.
But intermittent fasting can have side effects, she says. As blood glucose levels fall, this can spark headaches, and result in feelings of dizziness and weakness.
“Studies of those fasting during Ramadan have shown that during fasting, severe hypoglycemia can occur. Intermittent fasting may not be suitable for the elderly, as low blood glucose levels can increase the risk of falls.
