How Do You Calculate Your Own Appropriate Calorie Deficit?

Posts: 26
Apparently people are sick of other believing that 1,200 calories a day is healthy, but nowhere can I find a semi-understandable way to calculate how many calories I SHOULD be eating.
Should the deficit be 500 calories? Should I eat back all of the calories I burn off at the gym, or 60%?
I also don't know if I should be doing high intensity cardio intervals mixed with weight training, or lots of low intensity cardio, or just weight training. I honestly have no idea! This place is a treasure trove of conflicting ideas.
I already read the "Road Map" post, and it was too difficult to understand as a beginner.
If it helps, here's a little about me:
Gender: Female
Age: 21
Height: 5'4
Weight: 142lbs
BF%: No Idea
Goal Weight: 125lbs
I haven't decided on the level of activity I would like to take up, because I can't figure out what is best for me. But I assume that when I figure out which type of exercise I should be doing, I will probably exercise 4-5 hours a week.

Bump.
Please help me, fitness gurus!0 -
The bottom link is a Google spreadsheet that a Great guy(heybales) set up, it will help you figure your Body fat% and calculate your numbers, I would suggest reading through all the info first.
Here is good info:

use this to figure your numbers if you want detail

I used this to help me figure out my bmr. i am supposed to eat about 1500 a day and since then ive lost weight, and i dont feel like im starving.
hope this helps0 -
Do you like to eat to a static number or vary it based on your workouts?
How active are you in the day?0 -
At your age go with cardio and low weights and more reps. Your body will respond quickly. Plus more cardio will burn off fat faster. Building muscles helps to burn fat but it also adds more weight so it can be confusing. You might want to try all different kinds of activities, dance, martial arts, swimming, zumba, pilates, yoga, orbitz, etc., because when you find one you really like, you'll want to go more often.0

In Place of a RoadMap (link posted by Railr0aderTon) is full of all the information you need. I used my FitBit to figure out what my average calories burned weekly (did the average of 6 weeks) divided it by 7 (days of week) to find my average calories burned daily. Then I subtracted 20% (which is roughly 500 calories) and ended up with 1700 calories a day to eat. I roughly burn 2200 calories a day (running days are higher while weekends are low). I keep an eye each week and how my deficit is and will be increasing my calories to 1850 soon as I increase my running times.
If you don't have a device like FitBit / BodyMedia then just figure out your TDEE (In Place of a RoadMap explains it all) and take 20% off (more if you have 30+ to lose and less if you have 10 pounds you can lower it)0 -

This should help you out. It's very easy to follow.0 -

What does age have to do with it?
Strength training is important to preserve muscle mass while dieting and has a slew of other benefits, including improved bone density. I would imagine that the OP is more worried about BF% than scale weight (I would hope anyway).0 -
I like this site when recommending calories... http://iifym.com/iifym-calculator/0

Honestly, it's trial and error. You can follow all the "Road Map's" and calculations but you're still going to have to find what works for you.0

I was having the same problem until someone walked me through this. First, go to the above link and fill in all the fields that are in YELLOW. Then, input/change the numbers on MFP to what they are in green.
I was getting really confused with the whole "to eat back or not" but since this already takes into account the ammount/how often you're exercising, you don't eat back your calories. I switched my "goal calories burned/week" to zero so it doesn't confuse me (I'm easily confused!)
For example, after all my numbers were in my TDE was roughly 2600. That's because I exercise 7 days a week so am in the "very active category". -20% of that leaves me with roughly 2000 calories that I need to consume in order to lose fat but retain muscle. Entering all these numbers in gave me a deficit of 400+ calories/day and a projected weightloss of .8lbs a week, which seems like a much steadier pace.0 -

Thanks so much for your help, guys!
Apparently my BF% based on the calculator as per my measurements is 27%. I would be more comfortable getting down to around 21-22%. I expected this number to higher, honestly. I should probably have my BF% correctly read at my gym, but it costs money, which I think it wrong.
My "Total Daily Eating Goals" should be 1,630 calories if I do 120 minutes of high intensity cardio and 120 minutes of weight lifting per week.
This was said to equate to a 0.8lb fat loss per week. It said that that doesn't necessarily mean I will lose 0.8lbs in weight a week though. Idk how long it will take me to get to my goal self, but everyday I put off doing the right thing as a day less that I get to enjoy a body I can be proud of!
I'm hoping to have made great strides by July 26th, my wedding day!
Thanks again0 -

I think that this is the best advice I've ever read : )0 -
If there is one area in which MyFailPal totally fails it's that the site does not offer members any information to help them decide how many pounds to lose per week. So many people - particularly women - are choosing the wrong deficits simply because they are unaware that we have limits to how much fat that can be oxidized in a 24-hour period.
To answer your main question, which [again] isn't addressed by MyFailPal, we calculate our deficits considering how much total fat mass we have and how much fat mass we wish to lose. Think of it as a maximum deficit in which fat reserves will be used as fuel since we all have a limit to how much fat that can be burned daily. The closer one reaches this maximum deficit, the more lean body mass is lost. If one goes over this max deficit, then only lean body mass, and not fat, is utilized.
Use this simple formula: 31 x lbs of total fat mass.
For me, 31 x 16 lbs = 496 max deficit
This means that my theoretical max deficit should be no greater than 496 calories since my body will not burn more than that amount in fat mass daily. However, based on real world practice, I choose no more than a 300 calorie deficit since I seem to lose excess lean body mass beyond that.0 -

Confused about this, to be honest. Gah, I feel like everything around here is confusing, and I'm typically not that dense lol. According to your formula, my max deficit would be 1,178 because apparently my total body fat is 38lbs so that would be 31 x 38. If that's the case, then my calories could definitely b at 1,200. I understand that "max" might be the operative word here, but how do I know what sort of deficit I can have and still be within a healthy range that won't cause me to plateau.
My ultimate goal here is to consume the least amount of calories without plateauing so that I can have the largest amount of loss in the shortest amount of time. I want to be healthy about this of course, but my wedding is just under 14 weeks away, so time is of the essence here.0 -
