Did I Mess Up My Metabolism?

Hi there. Hoping to get some new insight.

I'm a 31-year-old female, 5'8", approx 135 pounds. I've lost around 30 pounds using MyFitnessPal - I've always been very active, but I also love food and probably ate more than I should have and didn't pay attention to portion control. Once I started working out harder and carefully counting calories (using an HRM for workouts and a food scale to measure portions), the weight began to come off. However, even with adjusting calories downward, I'm now stalled. I set my base at 1330 calories per day, but I work out (intense cardio for at least an hour and a half) and burn at least 700 calories per day. I eat back most of my calories because, well, I'm hungry. I very rarely take rest days because I feel guilty - and I feel like I can't stay within 1330 calories without being really hungry. Heck, sometimes I'm hungry even when I eat 2,000 calories. My job is very sedentary, so I feel like I absolutely can't skip the gym.

I've been stalled at the same weight for over 2 months, and I feel like no matter how many hours I spend at the gym or how careful I am with food, I'm just maintaining, not losing. Could I have fooled my body into thinking it needs 1330 cal (plus exercise cal) to maintain? Is there any way to fix that?

Others have suggested taking a week off from logging and just eat what I want as a "reset," but I'm nervous about eating too much and feeling out of control. Any tips? I'm not looking to lose a lot more - 5-10 pounds at the most.

    Agree with Mr.M You simply haven't much left to lose. It will be much easier, and probably leave you looking much better if you slowly gain weight while doing resistance training (weight lifting). Try and gain around 1 lb a month. That will ensure the weight gained is mostly lean mass and not fat. After a prolonged period of muscle gain, you can again try a deficit and you will find that when you reach the same weight you are now, you will look MUCH better and more defined.

    If you are burning off that much and consuming that little, your definitely slowing your metabolism down. I don't feel you really need to lose much either! I am 5"9 and now 145 pnds up from 137 about a year ago. my body composition is much better though despite the weight gain! all due to weight lifting! I have been told that you can damage your metabolic rate, by eating very little. A personal trainer at a seminar I attended for my ceritification said they do testings where a woman normally RMR could be 1200-1300 and a client who had an eating disorder in the past was only 600 a day. probably best to try and get an accurate calculation try a online calculator inputting your stats. It can get you a starting point.

    Your b.m.r is 1370, so, in order to get that weight loss rolling, get the net calories to 1370 a day. If you need anything, you can message me.

    @collingmommy - I feel like that is what I'm netting - a little less, around 1300 per day. Hmm.

    @ars1300 - I'm still eating like 2,000 calories (or more) total per day - is that too little? It seems like kind of a lot to me.

    @vismal and @MrM - I guess my main issue is that I'm afraid to start doing more weight lifting versus cardio - I know when wearing my HRM, my heart rate goes WAY down when I do weight lifting - or really, any time I'm sitting or laying down to do floor exercises. Thus, it looks like I'm burning far fewer calories, which means I can't eat nearly as much as when I do, say, a half hour of running followed by spin class. That's what's preventing me from doing heavy lifting - I want to get as much bang for my buck (or in this case, calories burned for my time) at the gym... and I know lifting will show up as fewer calories on my HRM and thus, less food. How would you approach this?

    Thank you all so much for your help and advice.

    I know it sounds crazy, but.. It's not that magic number of 1370 net, then your body is holding everything. Our bodies are weird little things, you have to give then what they all for or you get no results. Like I said, go to fat2fitradio.com and look at the info. You will be pleasantly surprised

    HRM are only meant for steady cardio so they cant estimate heavy lifting calories burned. You are better off using a TDEE calculator and going off that vs what your HRM says as it can be inaccurate if you don't use it with the correct exercise. You may burn less calories doing heavy lifting than cardio but your body will continue to burn calories after a heavy lifting session as your body repairs your muscles and whatnot.

    I am 150lbs, 5'7, female. I maintain at 2,100 calories with 3x/heavy lifting for about 40 minutes each session. That's all the exercise I do.

    Thanks! That's a good point.

    I calculated my TDEE (with 7 days exercise) at 2255. So does that mean I eat that amount (minus like 10%) regardless of what the HRM says or how much I work out?

    I also calculated it via Fat to Fit (BMR), and I'm getting 2444 at the "very active" level (minus 10% to lose some weight). Do I use that regardless of exercise?

    Your TDEE calculates your exercise calories in with the total number so you would eat 10% minus your TDEE (or whatever percentage you decide). You wouldn't add extra calories.

    If I have a bad week or am sick, I will recalculate my tdee using sedentary/light active and eat that for the week. Usually my exercise stays the same.

    I'd stick with 2,225 - 10% and see how your loss goes. You can still wear your HRM if you like to see how you work out (I still wear my Fitbit even though I don't use it to calculate how much to eat) if it suits you. If you don't lose weight after a few weeks, reevaluate your numbers.

    Out of curiosity (not trying to be rude honestly, it's hard to tell tone with text so I'm clarifying), how much more weight do you want to lose? I've been told by my doctor I should weigh about 110 lb and I'm only 5'1. You're seven inches taller than me, and if you weigh 130 lb right now...

    I guess I'm just wondering how much lighter is healthy (I really have no idea), since you mentioned getting "bang for your buck" regarding burning calories, so it seems you're looking for weight loss, not muscle toning. I'm worried that if you want to be lighter, maybe I should be aiming for less than 110 lb.

    i am shorter than you and do less exercise, but my TDEE is around 2,200? which calculator are you using to get your TDEE?

    I think it is possible to mess up your metabolism with too much dieting. If you body is stalling it may be that you have just reached your natural weight - you are well within healthy guidelines - perhaps your body is trying to tell you something. If I were you I would continue to go to the gym to keep yourself fit and healthy and not worry about losing any more. Please don't get hung up on numbers, believe me it can become an obsession and really mess with your head. You have had a fantastic result and are a good healthy weight, I am sure you are looking fabulous so maintain it and enjoy it.

    you should eat around 1600 calories total daily (that is with the TDEE method) but it would also be advisable to do a program that has more resistance training. JM is more cardio than weight training. Also, set your macros around 40% carbs, 30% protein and fats.

    OP, I agree with MrM too. If anything you should have a very minor deficit and worry about recomp. It's actually not surprising that you are still not happy with your body and very close to being under weights. This is actually fairly common because too many people worry about weight loss not fat loss. The reason most people are unhappy with their body is from a lack of lean body mass. At this point, you can recomp for awhile or do a few bulk/cut cycles to gains some muscle back.

    Try the 5.2 lifestyle basically eat you calories on 5 days of the week and on the other 2 eat only 500 It may sound daunting but IT WORKS! Fill up with water or low cal things Ive lost 7lb in 6 weeks.

    Just to clarify, when you do 5:2, you eat at your maintenance or slightly above your maintenance on the non fasting days and then 500 on the fasting days. This is just a type of interim fasting. Essentially, you create your deficit on two days as opposed to a daily deficit. Over the week, it will produce the same results.
