7 Day Intermittent fasting diet meal plan All about the IF diet
The Intermittent fasting diet meal plan offers a time-restricted eating pattern.
So, how does this work? It recommends consuming food for only 8 hours of the day and avoiding food for the remaining 16 hours.
Some studies suggest that this method works by supporting the bodys internal clock, the circadian rhythm.
The easiest way to follow the diet is to incorporate this 16-hour fasting period into the time you sleep.
You can make the interval period coincide with the time of the day when you are active.
However, stopping eating 2-3 hours before going to sleep will be beneficial for your health, quality sleep, and weight loss.
So, should nothing be consumed in this 16-hour fasting period? Of course not. You still need to drink lots of water.
Apart from that, you can drink as much tea as you want .
Also, you can drink unsweetened coffee. But thats all. You cannot consume anything that is not zero in calories.
In addition, supplementing this diet with light exercises will always give better results and will bring you the result you dreamed of faster.
This applies to every diet you follow. Now lets look at how we should eat in the intermittent fasting diet meal plan day by day.
According to ClevelandbLab intermittent fasting also helps lower blood sugar levels.
The 3 Types Of Intermittent Fasting Compared
Fasting for five days with juice will just leave you cranky and hungry. But fasting for 16-24 hours throughout the week? Thatll leave you energized and leaner.
Intermittent fasting, as this diet method is known, is just as effective as daily calorie restriction for improving body composition, according to a 2017 study analysis from the International Society of Sports Nutrition.
Unlike calorie restriction, though, intermittent fasting doesnt require you to count calories all the timeand its better at preventing hunger.
Furthermore, intermittent fasting is especially good at helping you lose fat while maintaining muscle, rather than losing both , says Krista Varady, Ph.D., an associate professor of kinesiology and nutrition at the University of Illinois at Chicago and key researcher on intermittent fasting. According to a study analysis in Nutrition Reviews, intermittent fasting also helps improve total cholesterol and triglyceride levels in both overweight and normal-weight people. The best part: Theres virtually no downside.
There are three types of intermittent fasting: whole-day fasting, alternate-day fasting, and time-restricted feeding.
Youll see the same benefits from eachthat is, losing fat without losing musclebut, since each type incorporates a different fasting period and fasting frequency, some are better-suited to certain guys and fitness lifestyles.

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.
Alternate Day Fasting Approach
In the alternate-day fasting approach, the person eats every other day according to their wish and then fast on the alternate days.
If someone finds alternate day fasting tough, then that person can consume up to 500 calories even on fasting days but not more than that.
This intermittent fasting approach can help reduce the risk of heart disease and insulin levels.

Intermittent Fasting Diet Plan
To ensure that you get the most health benefits from intermittent fasting, its vital that you consume nutritious foods and beverages during the eating periods. Consuming nutrient-dense whole foods will help you benefit the most from this health regimen.
Although there is not a diet plan per se, incorporate the following during your eating periods:
Fruits: All fruits are good options especially oranges, apples, pears, peaches, bananas, and berries.
Vegetables: You may consume all the vegetables. Opt for many green, leafy options as well as broccoli, cucumber, cauliflower, tomato, etc.
Whole Grains: Avoid all products containing refined wheat. Opt for grains such as buckwheat, barley, quinoa, oats, rice, etc.
Healthy Fats: Skip all saturated fats. Choose oils made from coconut, olive, avocado, mustard, peanut, sesame, etc.
Protein: Choose lean protein options such as poultry, meat, eggs, seeds, nuts, legumes, lentils, etc.
During the fasting period, you may consume calorie-free drinks such as unsweetened tea , coffee , and water. These will help you stay hydrated. Avoid binging on junk food or over-eating during eating periods as this will prevent you from experiencing the positive effect of this health regimen.
Modified Alternate Day Fasting
If the thought of going an entire 24 hours without eating freaks you out, youll be happy to know that you dont have to do that with the modified alternate-day fasting plan.
Like alternate-day fasting, you will fast 24 hours, every other day. However, you are allowed to eat a small number of calories during your fasting window. The limit is 500 calories or 20-25% of your regular calorie budget.

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.
Heres What Happened When I Tried Time Restricted Feeding
Krista Scott-Dixon, PhD, Precision Nutritions director of curriculum, is a morning person.
I didnt want to give up my big breakfasts, so I chose evening fasting first. she says. I normally trained in the mornings, so this worked for me.
However, she noticed three things about her sleep when fasting in the afternoons and evenings.
First, she was much more tired. Once my battery ran out, I was done. Getting up the stairs to bed was a terrific ordeal, she says.
Second, although shed conk out quickly, she didnt sleep well.
Third, she woke up extremely earlyat a consistent 4am.
Later, she experimented with skipping breakfast and lunch.
At first, that felt like much more of a sacrifice, she says,
Eventually she got to like the efficiency of waking, grabbing a cup of tea, and getting straight to work. And she slept a lot better after a good meal in the evenings.
Bottom line: For any fasting schedule, youll want to experiment, tweak the plan, and do what works for you.

Are There Benefits To Crash Diets Over Intermittent Fasting
Crash diets always fail because losing muscle mass is counterproductive and even when you lose lots of pounds, the fact that you are losing several pounds of muscle means you dont look better. This is disappointing because when starting a crash diet with a goal of losing 30 pounds or more, in your minds eye you picture yourself returning to the body that had 30 fewer pounds of fat on it. Your new crash diet body doesnt look anything like you anticipated.
Plus you tend to feel lousy and all you think about is food.
When you engage in intermittent fasting, you do not cut calories, and do not enter a semi-starvation mode. On the contrary, although my weight has been reduced, I actually eat more now than I did before I started intermittent fasting because I dont want to lose any more weight. Thus, I am easily replenishing my liver glycogen stores every day, and sustaining my blood glucose at optimal levels which preserves my muscle mass.
All thats required is simply making the firm decision to commit to eating at prescribed times and sticking to it.
Why Does My Blood Sugar Go Up During Fasting
While this does not happen with everyone, it can occur due to hormonal changes that occur during intermittent fasting. Your body is producing sugar in order to provide energy for your system. This is a variation of the dawn phenomenon and in general is not a concern as long as blood sugars are not elevated the rest of the day.45

Alternate day fasting builds upon a 24 hour fast and is more of a weekly intermittent fasting schedule rather than a daily one. A typical schedule includes fasting for even days of the week and eating on odd days . With ADF you typically fast for 36-44 hours and then have a 12 to 8 hour eating window during one day.
When beginning ADF and longer fasts, make sure to break your fast gently with a food such as broth, milk , a handful of nuts, or something similarly gentle on your stomach to gently reawaken your digestive system.
Once you get good at the alternate day fasting, consider yourself an intermediate faster!

First What Is Metabolic Syndrome
Metabolic syndrome is a cluster of conditions that increase your risk of heart disease, stroke, and type 2 diabetes. These conditions include increased blood pressure, high blood sugar, excess body fat around the waist, high LDL cholesterol, and abnormal triglyceride levels.
Metabolic Syndrome is not new, and has become increasingly more prevalent. At the time of this writing, 1 in 3 older adults have this condition. However, fasting can play a key role in reversing many of these symptoms. Research consistently demonstrates that intermittent fasting is one of the best methods for reducing excess body fat and many of the conditions that go along with it.
In fact, type 2 diabetes, can be reversed with long term intermittent fasting. Type 2 diabetes in the last 10 years is being re-understood thanks to the work of Dr. Jason Fung and others. It is essentially a disease of chronically high insulin that progresses very gradually, typically for many years patients wont know that they have high insulin, then the begin to get symptoms of insulin resistance, then prediabetes and eventually , full blown type 2 diabetes.
Science Of Intermittent Fasting For Weight Loss
To understand the science of intermittent fasting, we need to look into the basics of nutrition.
And it is quite straight-forward: the food we eat gets broken down to molecules and ends up in our blood, which feeds the cells in our bodies.
Part of those molecules are net carbohydrates and our body turns them into sugar so our cells could use it for energy.
To be able to use sugar for the energy we need insulin, which is produced in our pancreas and spikes each time we throw in some food with carbohydrates.
Any excess sugars that we dont utilize get stored in the form of fat with the idea that we will use that fat for energy later, once we have no sugar left.
The best way to NOT end up having huge fat reserves is to spend the same amount of energy you get from food.
However, life is not perfect and many of us have lifestyles that limit our chances to move throughout the day. In fact, office workers tend to spend 75% of their waking hours sitting.
So, what can we do to lose or not gain weight?
One way to do it is to focus on increasing your energy expenditure through increased physical activity or in laymans terms exercising and doing sports. But you knew this one already, didnt you?
Another way though is to focus on consuming less food than you need for the energy that day and as a result, creating a caloric deficit.
And thats where intermittent fasting comes in.
