The Larger The Assortment The More Difficult It Is To Choose

Do Calories Matter When Intermittent Fasting?

Due to the skyrocketing popularity of healthy lifestyle, fitness, and weight loss, the media swarms with hundreds of various methods of toning up and shedding pounds. For those whose goal is to trim a couple of inches, the choice of a correct nutritional and workout plan becomes more difficult with the appearance of each new popular diet. As you know, each person has a different body type and requires a different approach to losing weight or packing on muscle. And such a great number of fad diets only confuses people and may even lead to health damage. If you are one of those people, who are sick of extreme calorie restrictions and unreasonable food limitations, then perhaps intermittent fasting, the 18:6 intermittent fasting, in particular, is exactly what you have been looking for.

These Dietitians Reveal How Many Calories To Eat On Intermittent Fasting And Still Lose Weight

Once you get used to going through long stretches of time without eating, intermittent fasting seems like a great way to lose weight and maintain it. There are other health benefits, too, such as improved digestion, more energy, and improved insulin levels. When your body goes through periods of fasting, it boosts the production of growth hormone, which helps you lose weight and gain muscle. While there are several different ways to do IF, the main tenets are still the same: periods of eating interspersed with periods of fasting.

But what do you eat during your feeding window? Technically, intermittent fasting just refers to when you eat, not how much you eat. “There are no rules about how much you should eat when you are not fasting,” Julie Upton, MS, RD told POPSUGAR. “The diet was designed so that the fasting period creates the caloric deficit so that you can lose weight.”

In fact, Kristen Mancinelli, MS, RDN, author of the book Jump Start Ketosis: Intermittent Fasting For Burning Fat and Losing Weight, said she doesn’t tell her clients to count calories. Instead, she advises them to eat until they feel satisfied. Since people who follow the 16:8 plan typically only eat two meals a day, they will naturally eat fewer calories since once they have acclimated to the fasting period, they tend to not get hungry outside of their feeding window.

S Man: Pick Your Wait Class

Weve given you the lowdown on IF before, but heres a little refresher for the new students in class.

While the foods above will give you the most obvious benefits from the diet, its the fasting part of IF that provides the oomph.

There are loads of IF plans, but most focus on fasting for a certain number of hours in the day or days of the week.

Heres a breakdown of the most popular IF models:

  • The 12:12 method: Fast for 12 hours a day and eat within a 12-hour window. If you eat your last meal at 7 p.m. and have breakfast the next morning at 7 a.m., congratulations, youre already an IF pro.
  • The 20:4 method: Fast for a full 20 hours and allow yourself one 4-hour window to eat.
  • The 16:8 method: Eat your daily food within an 8-hour window and fast for the remaining 16 hours.
  • The 5:2 method: Eat whatever you want for 5 days out of the week. For the other 2 days, men can consume 600 calories, while women can consume 500 calories.

IF isnt the only way to lose weight, and like any other method, it comes with some risks and downsides.

There are risks to IF, such as tiredness, irritability, and headaches. Dehydration is also possible if you dont drink enough water during fasting periods.

The fasting/feasting routine is also potentially unrealistic in the long term and may lead to binge eating during feasting periods, which wont support any weight management goals.

Its best to talk to a dietitian or nutritionist before embarking on IF its not for everyone.

Alternate Day Fasting : 2 Method

A Beginners Guide to Intermittent Fasting

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.

Intermittent Fasting Basic Philosophy

The very first thing that you’ll want to think about is how many calories per day you burn at rest just to stay alive.

For most people, this is going to work out to be about 10-11 calories per pound of body weight. If you’re carrying a very high amount of body fat it may be slightly lower than this, but for most individuals this is the best number to aim for.

So first, take your current body weight and multiply by 10 if you’re a female and 11 if you’re a male.

A Sensible Approach Makes More Sense

Weight loss as an endeavour is tasking enough. Adding the mathematical element of counting calories during intermittent fasting just makes it even more tasking.

Some people think you have to count calories on your eating days or eating window. You dont have to. You can if you want to. It wont do you any harm to count calories if it gives you further reassurance and confidence.

But for most people doing intermittent fasting, they dont bother to count calories when they have to eat. They just eat sensibly and avoid over-indulging. You really should not try to compensate for the days or hours you skipped meals.

You wont be doing yourself any favours. in fact, you would be making nonsense of the idea in the first place. Id like to think you are serious about weight loss and weight stability, so why ruin it?

If you are doing intermittent fasting and not losing weight, then theres a good chance you are doing compensatory eating. Compensatory eating is one of the reasons intermittent fasting wont work for you. Dont do it and indeed its not necessary to do it at all.

By compensatory eating, I am referring to making up for lost time in terms of food quantity during your eating window or eating days. Its pointless consuming 2300 calories in one meal, for instance, just because you skipped a meal or two.

So, if your daily calorie requirement is 2500 Calories, you would have to consume 20% of 2500 on 2 days of the week i.e 500 Calories.

Drawbacks Of 16/8 Intermittent Fasting

16/8 intermittent fasting may be associated with many health benefits, but it does come with some drawbacks and may not be right for everyone.

Restricting your intake to just eight hours per day can cause some people to eat more than usual during eating periods in an attempt to make up for hours spent fasting.

This may lead to weight gain, digestive problems and the development of unhealthy eating habits.

16/8 intermittent fasting may also cause short-term negative side effects when youre first getting started, such as hunger, weakness and fatigue though these often subside once you get into a routine.

Additionally, some research suggests that intermittent fasting may affect men and women differently, with animal studies reporting that it could interfere with fertility and reproduction in females .

However, more human studies are needed to evaluate the effects that intermittent fasting may have on reproductive health.

In any case, be sure to start gradually and consider stopping or consulting your doctor if you have any concerns or experience negative symptoms.

How Does Intermittent Fasting Work For Weight Loss

How Many Calories Do You Burn While Fasting – Intermittent Fasting Calories

Intermittent fasting was working perfectly for me, and it was easy to follow. I began to think more deeply about why it was working. Was my body changing because I was fasting for those 16 hours each day, or was it simply a trick I was playing on my mind to eat fewer calories? And if it was a trick, would my mind eventually figure it out?

In general, I think intermittent fasting helps people get more in touch with their needs, Varady says. Weve become accustomed to eating or drinking something every couple of hours. Wed never even noticed when were actually hungry or full. So when you go for longer stretches of time without eating, all of a sudden, your body becomes more attuned to it.

In my case, intermittent fasting made me more aware of my tendency to emotionally eat. Getting up early to get my young son to school, it wasnt as if I wanted to have that bagel and soda. I felt I needed that sugar rush to wake me up and get me going. Exercise replaced that without my needing to ride a sugar roller coaster every day.
