IF - does it have to be caloric restriction?

Answered on August 19, 2014

I looked around for the answer but couldn't find anything on this site. So this should hopefully just be a quick question.

If I was going to do IF from 4pm until 9am the next day, would I still try and get my normal amount of calories in for the day before fasting? Am I still getting the same number of calories but fitting them into a smaller eating window? Or am I going to have to reduce my total calories for the day? Thanks so much, y'all.

IF does not necessarily have to be restrictive in calories. There are plenty of benefits of doing an 18-20 fast then still eating your normal calories during the feeding window.

One of the main benefits is autophagy, or the catabolism of degraded or dead cells. Most of the stuff I've seen is anecdotal, but from personal experience, I can buy it.

Another way to look at it is that even if your consumption of calories is lower, i.e., 1600 vs. 2500/day need, your body makes up the difference in needs by drawing on your bodyfat stores (which is what most of us want!) This works particularly well if you are fat adapted. So although you are consuming less calories, your body still gets all its energy needs through the combination of dietary intake and stored energy (bodyfat). That's exactly the way nature designed it, but the key is to eat a Paleo diet, so your body isn't crashing because you aren't shoving Ho-Hos in your face every three hours.

Just my take. I IF everyday and eat about 1600 calories, 60-65% from fat, and have lost about 30 lbs in 3 1/2 months.

According to The Paleo Answer IF will naturally lower your calories by 30%. Really depends on your goals. Do you want to lose fat, lean out or bulk?

IF does not need to be calorie restricted. It tends to be if the eating window is short because it can be hard for some people to eat enough in a short window. If you eat all the calories you need during your eating window, then it qualifies as IF.

If you IF once a week or every other week etc... For less than 24 hours. Then there is usually a calorie deficit. You would want to taper off your fast with a normal or even lighter meal.

If you are doing a lean gaines protocol where you are fasting every day then there is no calorie restriction.
