I need help finding the correct caloric range (TDEE)

in Health and Weight Loss
I am brain dead when it comes to TDEE. I have not been doing it. Can someone help me with the calcuations? I have been eating at about 1500 cals and I am completely washing out here. I am exhausted, my hair is falling out a bit and I am thinking of quitting. I need help.

I am:

48
female
258 lbs
I swim an hour a day, burning about 1000 calories (I'm not overestimating - it's an aggressive swim)
I do some pushups, situps, unweighted squats, lifting and such, about 30 minutes a day.

I looked on the TDEE site and there are several methods to calculate what I should be shooting for and I don't know which to choose. Is there anyone who can help me?

I'm starving.

Thanks in advance.

    Try using this spreadsheet. It is done by HeyBales in this site and is what I use. I agree with you that TDEEs can be all over the place depending on what site you use.

    I hope this helps.

    I like fitness frog's calculator.

    What is your height?

    Of course, chronic dieting, medications, and other hormonal alterations like PCOS, menopause or underactive thyroid can affect your metabolism so you have to take it with a grain of salt. Your ideal deficit off your TDEE also varies. How did you come up with 1500?

    At your weight, 1700, 1500, won't really matter. If you use the TDEE method, DO NOT add back and eat exercise calories.

    Why not just use MyFitnessPal's numbers? It works, and especially at your weight you shouldn't have trouble losing with an aggressive deficit. The TDEE stuff is much more important as you approach a healthy weight.

    Keep It Simple.

    You will become accustomed to the low calories after a while. Stick with it.

    I used to be 5"11, have a big frame. I'm 5'8" now.

    According to fitness frog, your TDEE would be between 2900-3200 depending on whether you would consider your exercise moderate or heavy -- since it's an estimation, I'd round to 3000. The IIFYM calculator, which uses a different and probably more accurate formula, also puts you around 3000.

    A 2 lb loss per week would be a 1000cal daily deficit. Right now you are at a 1500 cal daily deficit if your total intake is 1500. That's a high deficit. If you're hungry and weight loss has stalled at 1500, I would try eating closer to 2000 cals per day (gross, no additional for exercise). Hopefully that would help with hunger and sustainability and you should lose at a good clip even if the TDEE is a bit off. You could also try adjusting your macros, make sure you are getting enough protein as it tends to be more satiating.

    Two questions I want to ask you, since you say your hair is falling out. Have you started menopause, or peri-menopause yet? And have you had blood work to check your thyroid levels? OK, let's make it 3 questions. Do you have any autoimmune diseases?

    You should definitely get your thyroid checked if you have not. Hair falling out is not normal unless you are starving yourself, like annorexia.

    I've had the same question! I've used the calculators at Fitness Frog, IIFYM.com, Fat 2 Fit Radio, and Scooby Workshop. I get a range of values for TDEE -20% from 1750 to 2200 calories. Maybe it's because they measure activity levels differently? Some ask about hours of activity per week, versus days/week you exercise.

    So far I've been eating around the 1950 calorie range and losing weight at a pretty decent rate (slightly more than a pound per week). I'm female, 186 lbs, 39, 5'4", and do a combination of strength training and cardio exercise between 5-6 times per week (this week I did about 390 minutes of exercise at 65% max HR or higher). So I would think that someone of your height, weight, and activity level should be eating more like 2300-2400 calories per day to lose around a pound per week.

    Yes perimenopause, thyroid is perfect, no autoimmune disorders.

    Some of the hair issue might be from chlorine breaking off my hair. I'm not sure.

    I'm not anorexic.

    The perimenopause is a pain. I missed this last period. This has been happening since I was 43 or so.

    You shrunk 3 inches?

    Yes. Three inches. I T-boned a car in 1988 that ran a stop sign and destroyed three lower lumbar disks. All of my loss has been in the spine. I still have super long legs and monkey arms. And 12 inch long feet.

    Do I calculate my height on 71 inches or 68?

    98% of my bones are still that of a 71 inch person.

    Boy. Sorry to hear that. I have no idea on which to choose. Why don't you take something in the middle? You can always adjust if you aren't getting the results - and it shouldn't be more than 50 or 60 calories difference for an inch and a half.

    I would do the 68 inch since you lost the height in your trunk and that is where most of the weight would be in a body.

    It doesn't make a significant difference.

    Ok. The calculator says 2566 is for light activity, 2892 for moderate, 3214 for heavy.

    I do swim an hour every day, except today, but I don't do much else. I don't work and am, frankly, lazy.

    If you were me, where would you set the cals on the MFP goals? And am I supposed to then eat exercise calories?

    Just trying to get this straight.

    Why don't you start with 2566 and see how you feel and whether you get the results you're looking for? Do not eat exercise calories back if you are using this method--that energy expenditure is already accounted for in the TDEE.

    What calculator?


    If you used some offsite TDEE calculator, you DO NOT eat more on exercise days. Only you can choose your Activity Level - and whatever the calculator suggested is what you should use. They are all a little different.


    If you use MFP, just set it to Active & "Lose two pounds per week" AND eat back the extra calories you receive from exercise.

    Pick one.

    At your weight, you can afford to have a large deficit. Just use MFP, keep it simple.

    What you don't want to do is to keep changing it. The only way you can gauge the effectiveness of your plan is to be consistent and keep good records. No matter which method you use, they all depend on accurate record keeping over a period of time before making any more changes.

    That means a digital food scale, and scrupulous food entries every meal. If you choose MFP, just use all their numbers, including their exercise numbers. It is set up in a specific way - just trust the program, and keep good records.
