Eating at TDEE - 20%. Help! Does it work?

Hello!

I read all of the information on eating at TDEE - 20%, as opposed to 500 calories less than your BMR as is sometimes suggested. So I basically went from being told to eat 1200 calories (MFP suggestion based on wanting to lose 1.5 pounds a week) to 1800 calories based on the TDEE -20% equation.

I am so scared of eating this much! If any women have done this can you share your stories/experiences (i'm a woman so my experiences with weight loss might be different than a man's)? Did it take a while for the weight to come off or did you see it immediately. I do agree that 1200 calories is too low but 1800 seems so high.

If anyone can tell me about their thoughts on it, that would be great! My stats: 29 year old female, weight is 150 pounds. I have around 32% body fat (based on calculations online and a trainer recently tested it). I work out 3-4 times a week, twice with resistance training, twice with high intensity cardio. I don't need to lose weight quickly but I do want to see it move each week.

Suggestions? Thanks in advance!

    Welcome... Yes, It IS scary, isn't it?! The thought that actually fueling ourselves to function, and enjoying food is contrary to most things we've been taught so far.

    If you'd like... you can add me, and I can have my female friends add you. We've all had success. We all love food. It's a beautiful thing.

    Hello,

    Thank you so much! That would be great, I will definitely add you. I'm new to the site so it might take a minute for me to figure it out. Thank you so much!

    Yes, tatd_820, it is! I am trying to wrap my head around eating more and then also going along with the plan as I (hopefully) drop weight! Thats why I'd love suggestions from people who have done it and seen results. I also want to know if I should be patient in seeing them and knowing roughly what to expect. I don't want to be thinking its not working just because I haven't stayed with it long enough :happy:

    for the record, if you go from 1200 to 1800 fast, you'll probably gain a little weight while your body adjusts to the new amount. Better to gradually up your calories over about a 1 to 2 month period to let your body adapt, I'd say anywhere from 100 to 200 calorie increase with about 7 to 10 days allowed to let your body settle. It's a little different for everyone, but that's a pretty standard method.

    So far my experience eating more has been amazing! I have a lot more to lose than you, but the road doesn't seem as long and arduous knowing I don't have to feel hungry all the time to lose weight. Don't be afraid!

    I started out at 197lbs in December (but that was the last time I stepped on a scale; after Christmas it easily could've been over 200). I'm a 5'0 female so there's not a lot of places for that weight to hide, haha. I tried netting 1200 for a couple weeks and did lose a few pounds, but I was always feeling hungry and obsessing over the tiniest amount of calories. I switched to TDEE-20% sometime in the end of January, I believe. I average 1950 calories gross, sometimes more, sometimes less (but never less than 1700).

    Yesterday I weighed in at 177.75. I do power yoga 3-4x a week, and HIIT with a trainer 2x a week. The only week I've seen the scale go up was one week due to the time of the month, ugh. No, it's not the speediest weight loss, but I don't feel deprived, I haven't had to cut things I enjoy out of my diet, and there's always room for chocolate. :P It totally works!

    I've just started with this too and I'm somewhat confused. If you're eating at TDEE - 20%, do you eat your exercise calories back? I know cals are included for general activity level but if you're doing something extra do you eat those cals?

    No, you factor your exercise into your TDEE number so you don't eat back exercise calories. Maybe if you did something way different in a week than you wouldn't normally do when you factored your TDEE, you can eat a bit more on that day to compensate.

    Hi SMN76237! Thank you! This is great to know! And congrats on the weight loss :drinker:

    I'm a little confused though - your calorie intake is 1950 when you weighed 197 pounds but mine is supposed to be around 1850 and i weigh 150. Does it sound right that I'm only eating about 100 calories less than you were when you weighed 197? About how many calories are you eating now? And have you lost the 20 pounds by consistently eating 1950 calories? Sorry for all the questions :embarassed:

    Keep up the good work!

    Essentially its a different way of looking at weight loss. Eating 500 calories below your basal metabolic rate gets you eating WAY too low. It slows down your metabolism and changes your hormones so that you don't burn as much fat. You also lose muscle mass (and guess what? Having more muscle mass means you burn more calories per day).
    Calculating your TDEE Is a way to find out how many calories your body REALLY burns in a day (taking into account your sex, age, body fat percentage and weight). Then subtract that number by 20% and you should have the amount of calories you should eat in order to still lose weight. It may be a slower weight loss but its promoting health, making sure your metabolism isn't slowing down and your body isn't working against releasing fat or breaking down muscle.

    Thanks for this... I guess I can take a little weight gain/adjustment period. As long as it comes off after!

    Thanks! :) How tall are you? I'm pretty short (5'0) so that could account for my number not being much higher than yours, although 100 extra calories every day over a week is actually a pretty big difference!

    I am pretty bad at hitting the same number every single day, so don't use me as an example for that, haha. For example, last week there were 3 days I ate well over 1950, so i compensated by eating a little less than 1950 the other days (but like I said, nothing extreme, more like 1750-1890).

    Depending on how tall you are, at 150 you probably don't have too much to lose, so even TDEE-10% would probably work for you. None of the calculators and stuff are exact. You kind of just have to pick a ballpark number and see how it feels and works for you. That was probably the hardest part for me to come to terms with!

    Hey! I just recently increased my calories from1200-1900 based on the TDEE-20% information I have been reading on the forums.

    I am so happy I did! I have lost more weight and I'm not starving and miserable all the time:)

    At first I was just using the MFP app to track calories and followed the 1200 suggested guideline, but thankfully I signed onto the actual MFP website and discovered these forums!! Seriously, I feel so much better now! There is a lot of information on these forums and I'm thankful to all of those who spend time educating the new MFP members.

    Hope your transition to higher calories works as well as mine!

    I'm so glad you posted this, i'm going through the same thinking right now. I have been on this site and logging for about 5 weeks and lost about 16lb. I just did the TDEE-20 and it wants to up my calorie from 1500 to 2400. This just sounds crazy to me and i'm not sure what to do either! I'm 6'2 255lbs.

    I'm certainly no expert but 1500 cals seems awfully low to me for someone who is 6'2.

    Yes, I asked the guy who wrote about the post on TDEE-20% about eating back exercise calories and he said NO, you don't eat back what you exercise.

    so this is a subjective argument. By that I mean it depends on what you calculate your TDEE with. In other words, if you factor in your exercise sessions into your TDEE then you are correct, you would not include extra calories for exercise. If you don't add in your exercise then you would.

    I make this statement because with regards to MFP it's an important distinction. MFP DOES NOT INCLUDE EXERCISE in your maintenance calories. And thus, has you eat back exercise calories.

    Neither method is better, it's merely a matter of preference. MFP works, and factoring in TDEE with exercise works as well.

    Although factoring in exercise to your TDEE works better for people who are very consistent with their exercise. and MFP works better for both beginners and for people who don't have a regular workout schedule.
