Question about Intermittent Fasting and where excess cals

AnswerzPwease

I'm very new to this, so this may be a stupid question, but its one I don't know the answer to and everyone has to learn at some point.

So on IF, you would eat 8 hours per day and fast for 16 - correct?

1pm _ _ _ _ _ _ _ _ _ 8pm

TDEE: 896
Calories Eaten: 1800
Difference: +904 calories

Would your body, because it has no need for those 904 extra calories in those 8 hours, store it as fat?

And do you then rely on the other 16 hours of fasting to burn those 904 calories, before burning more fat?

Or is it more complicated than this?

where are you getting a TDEE of 894? i think you may be mixing some numbers up...

anyway, your over thinking this. your body is constantly storing and burning fat in cycles, so for say those 8 hours you eat, you may store some fat yes, but as long as your TDEE is greater than your calorie intake you will burn off more fat than you are storing. its the same for someone who isnt practicing IF, just that the cycles of burning and storing fat are longer since the time you are eating is more drawn out

2700 TDEE for the day divided by 24 hours = 112 TDEE per hour.

112 x 8 hours of eating = 896 TDEE for those 8 hours

112 x 8 hours of eating = 896 TDEE for those 8 hours

i see where your getting that thinking from but its kind of the wrong way to look at it. your TDEE is a daily total, assuming your keeping the same level of activity throughout the day you will burn the same amount of calories in the 8 hours that you are eating compared to 8 hours of fasting.
so your tdee is 2688, you ate 1800, your daily deficit is 888 calories
if you hadve eaten those 1800 calories over a 16 hour span your daily deficit would remain the same

I'd say it's less complicated than that.

Just find your daily TDEE, and take a cut from it. THOSE are the calories you should be eating. It doesn't matter if you spread them throughout the day, from 1pm-8pm, or 9pm-10pm. Just eat that number of calories, and you should lose weight.

It's actually quite simple my friend.. If your caloric goal is 2700 then you eat 2700 calories during your eating window every day.. If 2700 calories is your maintenance or your deficit, than no, it will not be stored as fat... Stay well

I would strongly encourage you to discuss this with either your primary care physicain or a registered dietitian.

Well, some consider 16:8 as IF but many dont as well. Some see it as just having to eat at a deficit and skipping one meal.

It doesnt work that way in just one day actually for cals to be stored as fat or used as energy. It isnt ike the body says after the calender day is over "oh, I had 1600 extra calories today than I burned so now it will be stored as .5lb of fat".

If you are doing the 16:8 you will still need to count those calories and eat at a def just as you would if you were not fasting those 16 hours.


Whenever something new gets big there are programs that try to adjust it to make it easier and promise the same results.

Intermittant fasting usually is around 20-24 hours of fasting (up to 500 cal) and then about the same time frame of eating your TDEE of which mine is 2200-2500. It is when the body experiences those longer fasts that you see the better benefits.

BUT many see that as too tough so some experts tweek it to make it sound easier.

The lure of IF is having to really restrict only on those fasting days, and eating to your maintenance on the other days. What it does is create a deficit over a week, month, or whatever time frame. The 16:8 is a way of fasting that basically just skips a meal but you still need to make sure you eat at a def during those 8 hours.

Ok thanks!

You are still burning calories during the hours you are fasting. So you TDEE (total daily energy expenditure) is still 2700.

You're way over complicating things...

There's a few different styles of IF - LeanGains 16/8, 5/2, Eat Stop Eat, Warrior Diet, etc. Choose whichever template or approach you want, it doesn't make a difference.

Whatever approach, with weight loss being your goal you still need to end up in a caloric deficit. If TDEE is 2700 you would need to create a deficit below that and eat in the applicable time frame, that's it. Also, don't fret and go into panic mode if you exceed the window...

It's just an eating mechanism to control hunger which has subsequently proven meal timing (personal performance excluded) to be irrelevant to it's impact on body composition.

^^^ This!
Would only add - do your research, pick a template follow the template . Too many people don't do the research and just cherry pick random bits and pieces then wonder why results aren't as expected.
