How Many Calories Should You Eat When Intermittent Fasting?

So my wife and I are trying to start on the IF journey . Its harder than we thought. How can she do coffee in the mornings without throwing off the benefits of the fast? She doesnt care for black coffee, but the chokehold of caffeine has her in its stimulant grip, and I dont want to die in that ditch today.

I, too, live and die by that a.m. cup of coffee. But this person is overthinking it. The best thing to do is simplify your routine. Have your morning cup of coffee exactly as you like it and break your fast then. For example, if youre doing 16:8 , have your coffee at 8 a.m. and your last meal at 4 p.m.

Supplements More Likely To Break A Fast

  • Gummy multivitamins. These commonly contain small amounts of sugar, protein, and sometimes fat, which could break your fast.
  • Branched-chain amino acids . BCAAs appear to trigger an insulin response that opposes autophagy (
  • ).

SUMMARY

Supplements may be used during fasting periods, although some may be better absorbed with food. Supplements that contain calories or sugar are more likely to break your fast.

To break your fast, start by eating gentle foods and be sure not to overeat.

Weight Loss And Fat Loss

Eating during a set period can help people reduce the number of calories that they consume. It may also help boost metabolism.

A 2017 study suggests that intermittent fasting leads to greater weight loss and fat loss in men with obesity than regular calorie restriction.

Research from 2016 reports that men who followed a 16:8 approach for 8 weeks while resistance training showed a decrease in fat mass. The participants maintained their muscle mass throughout.

In contrast, a 2017 study found very little difference in weight loss between participants who practiced intermittent fasting in the form of alternate-day fasting rather than 16:8 fasting and those who reduced their overall calorie intake. The dropout rate was also high among those in the intermittent fasting group.

Level Of Effort: Hard

Limitations: Its 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. Youll 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, youre 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.

Intermittent Fasting Food List: How To Choose The Best Foods

Eating during intermittent fasting is more about being healthy than just rapidly losing your weight. Thus, it is critically important to choose nutrient-dense foods such as veggies, fruits, lean proteins, and healthy fats.

The intermittent fasting food list should contain:

1. For Protein

The Recommended Dietary Allowance for protein is 0.8 grams of protein per kilogram of body weight. Your requirements may vary depending on your fitness goals and level of activity.

Protein helps you lose weight by decreasing energy intake, increasing satiety, and boosting metabolism.

Besides, when combined with strength training, increased protein intake helps build muscle. Having more muscle in the body naturally increases your metabolism, as muscle burns more calories than fat.

A recent study suggests that having more muscle in your legs can help reduce belly fat formation in healthy men.

The IF food list for protein include:

  • Poultry and fish
  • Dairy products such as milk, yogurt, and cheese
  • Seeds and nuts
  • Whole grains

2. For Carbs

According to the Dietary Guidelines for Americans, 45 to 65 percent of your daily calories should come from carbohydrates .

Carbs are the major source of energy for your body. The other two are protein and fat. Carbs come in various forms. The most notable of them are sugar, fiber, and starch.

Make sure to choose foods that are high in fiber and starch but low in sugar.

The IF food list for carbs include:

  • Sweet potatoes
  • Chickpeas

3. For Fats

  • Avocados

Mistake #: Youre Eating Too Many Calories

Do Calories Matter When Intermittent Fasting?

“Does anyone else eat like crazy right when the fast is over and is it normal to have a huge appetite during the feeding period? It is hard for me to get full after a 20 hour fast and I just eat the whole 4 hours. LOL.”

Id venture to guess that this person is eating more calories than whats needed in that 4-hour window. So instead of laughing your way through a marathon all-you-can-eat session, plan for how youll break your fast. Stock up on high-protein foods and/or high-fiber foods . Theyll not only fill you up, but will keep you feeling full.

“If I do a 20:4 fast then I should consume 1500-2000 calories within four hours? Am I understanding this correctly?”

Technically, yes. But depending on a persons body size, eating 2,000 calories in a 4-hour window might not yield any weight loss. I dont know this persons size, though. Now, most people lose weight on 1,500 calories, but one of the pros of IF is that its hard to eat a ton of calories in a short window of time. For some, following IF is an easier way to cut calories and lose weight than simply following a traditional calorie-restricted diet. So if you cant hit the 1,500- or 2,000-calorie mark in 4 hours every day, its OK. If falling below 1,200 calories a day becomes a regular habit, though, reconsider your diet plan. If youre not sure how many calories youre consuming, track them in a free app like MyFitnessPal.

Recognizing True Hunger Matters

It is worth noting that recognizing true hunger is a skill many of us have lost. The refined foods that makeup so much of the standard American diet get digested and absorbed quickly into the bloodstream. The resulting blood sugar spike is followed by an inevitable crash that brings hunger back sooner than expected.

On top of that, years of eating these low-value foods have left many of us insulin resistant, which means that even if we take in a lot of quick digesting calories, our cells resist the energy, and our cravings for more food never go away.

Bottom Line: If your diet was poor before coming to intermittent fasting, you might find it necessary to remaster the skill of recognizing true hunger. Until then, its a good idea to keep track of how many calories you are consuming.

Should You Do Intermittent Fasting And The Keto Diet

We have a crazy extensive guide on the Keto Diet in case youre not familiar with it, so here it is in a nutshell:

This process is called ketosis, and there are two ways for a body to enter ketosis:

Eating in a way that induces ketosis .FastingHey, thats what youre reading about right now!

We actually have an amazing success story here on Nerd Fitness, Larry, who followed our strategies, went Keto and start intermittent fasting. He ended up losing weight, getting stronger, AND overcame the challenges of rheumatoid arthritis !

Heres how the fasting portion of it works:

As your body enters a fast period when there are no sources of glucose energy readily available, the liver begins the process of breaking down fat into ketones.

Fasting itself can trigger ketosis.

Fasting for a period of time before kicking off a Keto-friendly eating plan COULD speed your transition into the metabolic state of ketosis, and fasting intermittently while in ketosis could help you maintain that state.

I personally love fasting for the simplicity: I skip breakfast every day and train in a fasted state. Its one less decision I have to make, its one less opportunity to make a bad food choice, and it helps me reach my goals.

WHY KETO + IF WORKS = eating Keto can be really challenging. And every time you eat, its an opportunity to do it wrong and accidentally eat foods that knock you out of ketosis.

Youre also tempted to overeat.

Your value may vary!

You need to decide what works for you.

I Didn’t Sleep Very Well

I’m not sure if this was one of the results of intermittent fasting, but I noticed that I didn’t sleep very well during my experiment. After a few days, I woke up multiple times during the night feeling super thirsty and had to get up to drink water before I could fall asleep again. I tried to adjust the types of food I was eating to fix it. Other bloggers who have tried the diet reported similar problems, but I couldn’t find concrete research linking the issue with fasting besides my fellow IFers accounts. I normally don’t have a problem sleeping, so this was definitely a negative side effect.

Thinking About Your Activity Level

Finally, last but not least, you need to think about your activity level. Those who are more active throughout the day are going to be burning up more calories total, so this needs to be considered. If you’re working a desk job, you’ll hardly burn any further calories, while if you’re on your feet all day long, you’ll be burning up far more.

Use this as a guideline.

Those whove tried the 16:8 diet say how much more productive they are during fasting hours, spending less time stressing over food and more time channelling their energy into other beneficial tasks throughout the day.

Figuring Out Your Basal Metabolic Rate

Intermittent Fasting: How Many Calories?

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.

Intermittent Fasting May Be As Effective For Weight Loss As Cutting 500 Calories A Day Research Suggests

Diet plans that limit when you eat, and not much else, can lead to weight loss and improve metabolic health, according to a new review.

Intermittent fasting a diet that reportedly helped stars including Jennifer Aniston, Kourtney Kardashian, and Chris Pratt shed unwanted pounds, according to People has been transcending its status as a celebrity fad as research about its weight loss and other benefits continues to emerge. The latest, a review published in October 2021 in Annual Review of Nutrition found that intermittent fasting leads to roughly the same amount of weight loss as traditional calorie-restrictive diets, and may improve other markers of cardiometabolic health as well.

One of our main findings was that people who do intermittent fasting lose about the same amount of weight as people on a regular calorie-restriction diet that cuts out 500 calories a day, says lead author Krista Varady, PhD, researcher and professor of nutrition at the University of Illinois, Chicago.

Additionally, Dr. Varady notes that intermittent fasting appears to help with metabolic health. It did help lower blood pressure, she says. Some studies reported decreases in LDL cholesterol and triglycerides, and insulin resistance.

So How Many Hours Should You Fast

When you explore the beginners guide to intermittent fasting, you may find these schedules very restrictive and difficult to follow. Its a good idea to start slow and fast for 12 hours and eat for 12, or fast for 14 hours and eat for 10.

For women, the 14:10 schedule is easier to follow. For men, this can vary as some men find alternate-day fasting easier to follow.

Working your way slowly will make it easier for you to adjust to a certain intermittent fasting type. You can eventually increase the fasting periods and decrease the eating windows.

What Are The Benefits Of A Keto/if Diet

Proponents of combining IF with a keto diet for weight loss suggest that the metabolic effects are one of the biggest benefits.

Unlike many weight loss strategies that focus on significantly reducing total calories, the Keto/IF approach doesnt necessarily require a decrease in caloriesonly a change in where those calories come from, and when you eat them. Many individuals opt to decrease total daily calories, but only slightly.

The result is that your body burns fat stores due to ketosis and fasting rather than low calorie intake. When ones goal weight is met, its suggested that maintaining weight loss is not as difficult since total calorie level and metabolic rate for not forced to decrease significantly.

Another benefit suggested by Keto/IF books is that fat provides satiety and suppresses appetite. Think about the last time you ate a meal really high in fat then think about how you really didnt even think about food, hunger, or appetite for a large remainder of the day. Since the majority of calories come from fats and oils, theres natural appetite suppressiona particularly nice perk when one is trying to maintain a 16-hour fast.

Wont Intermittent Fasting Burn Muscle

5 Healing Benefits of Intermittent Fasting

That depends on the person and the duration of the fast. During fasting, the body first breaks down glycogen into glucose for energy. After that, the body increases body fat breakdown to provide energy.

Excess amino acids are also used for energy, but the body does not burn its own muscle for fuel unless it has to.49

Some studies, however, suggest that leaner individuals are at higher risk of lean body mass loss, and even reduced metabolic rate. Yet it appears this is less of a concern with overweight subjects.50

In my experience with over 1,000 patients on various intermittent fasting regimens, I have not yet seen a single case of significant muscle loss.51Learn more
