    I appreciate the replies. But what I'm really trying to find out is will doing this a couple of times a week cause excessive muscle wasting? Or is that not really a concern?

    What do you do on the other 4 days of the week? Are any of the 3 days consecutive?

    I haven't read all of the responsed but did read a bunch....so I apologize if this was asked. But how are you calculating your calorie burn? 1500 calories in one day is a lot to come from exercise.

    I think it would depend on what calorie level you were eating at .. 1500 per day times three 4500 per week .. I have about 5250 per week trying for 1.5 per week loss .. .. so if your eating at maintaince every day and using this at calore reduction ??

    Good luck

    That's what I'm trying to get at. 4 days out of the week I'm not even 300 calories below maintenance. That's why I'm wondering if it really matters that on three days I have a big deficit. Some seem to think they are answering my question when they aren't. And others seem to get p.o.'d because I'd like more than one person's thought on the matter. Geez people, if it's such an inconvenience to give your input then don't! This is not toward you red99ryder.
    How is this NOT relevant to your question? Do you think you're going to keep building muscle while your hair falls out and your bones get brittle?
    I said his links (which where were about menstrual dysfunction) weren't relevant to my question.

    Other days are 200-300 calories below maintenance. The three days are not in a row...at least one or two days between them. Thank you for taking the time to try to figure out my question.

    Yes, someone asked. It's usually from about 3 hours of competitive racquetball. Basing it on MFP and other sites to try to verify calorie burn. Granted that amount might not be accurate but it's the best info I have.

    The links are not about menstrual disorder. They are about low energy availability, which leads to low estrogen (lower than you have even now as a 50-something woman), which leads to an inability to regenerate bone tissue, which leads to osteoporosis. That adaptation happens within 2-5 days of the onset of low energy availability. How many calories do you eat all week long? How many calories do you burn via exercise all week long? Subtract the latter from the former and then divide by 7. Then multiply your lean mass in kg by 30 and compare the two numbers.

    Also, if by "his" you mean mine, I am a woman.

    MFP tends to overestimate calorie burns. If MFP says 1500 calories burned, it's probably actually somewhere in the 750 to 1200 calorie range.

    So over a week you have a 5300 - 5700 calorie deficit? I gotta be honest, that sounds dangerous. Why are you eating at a deficit on the other 4 days? Why not try to make some of those 1500 calories back up on the days you don't play racquetball?

    But I think if you are looking at weekly deficits and those are still within a non-crazy range, you should be fine even with big deficits on certain days.

    I just did a quick calculation, supposing your only exercise is those 1500 per day for 3 days, you are netting 800 calories per day. That's a big old no. If you do other exercise on other days, that is reduced again. If you are someone who gets quite a lot of incidental steps in a day, it further reduces it.

    I hope at the very least you are also doing some strength training as all that cardio is not supporting lean mass retention.

    Bottom line, you need to eat more. If this has always been your approach to weight loss it isn't any wonder you keep losing muscle.

    Again, you need to look at overall averages and your numbers are worrying.

    Just gonna go ahead and quote myself here. You are netting 800 or below on average across the week. That is not okay.

    Where that deficit comes from, whether it's 3 days or 7 is irrelevant. Your average deficit is too large to support basic bodily function and lean mass.

    Thanks for your reply. I just checked. I'm netting closer to 950 calories per day. I'm averaging about 5300 calorie deficit a week or 757 per day. That should equate to about 1.5 lb weight loss per week. I've just started back on this fat loss journey recently and I don't want to lose muscle like I did last time. That's why I'm trying to make sure I get this right. I thought between 1 and 2 lbs a week is an acceptable goal. ??? I do try to do some strength training but it's just not "fun" so I don't do it much. I appreciate your input. I guess you answered my question...basically it doesn't matter so much about those three days as long as over the week it averages out to a more acceptable number. I was just concerned those 3 days were going to eat up my muscle mass. I guess if I wasn't trying to lose this weight as quickly as possible it would be moot and I could eat more on those workout days. But since I don't have much of a deficit on those other days I'd like to take advantage of the high calorie burn days.

    My sincerest apologies. I didn't take the time to look at your profile. My mistake. The little thumbnail photo on my device isn't very clear. After looking at your profile I'm am highly impressed with your success. Congratulations!!! That is awesome.

    Thank you and no problem. I am going to pretend that it was because I am so muscular. *flexes* :)

    Calorie deficits should be reasonable (20-25% of tdee). Otherwise you risk dipping into muscle mass to fuel your burn. When weight loss slows, drop calories by 50 cals/day to see if that gets things going again. Don't go below your bmr.

    To retain muscle you would probably do better with an average 500 cal deficit, or a 1lbs a week loss.

    Even though you don't like it as much as cardio, some kind of resistance training or weight lifting will preserve some, not all muscle as you lose, as will a protein level of .8-1g of ideal body weight.

    What you are doing now, only cardio and a high deficit may contribute to a higher muscle loss than you want, or is needed.

    You may find it useful to look up intermittent fasting protocols where the calorie intake for the week is alternated between maintenance days and low calorie fast days. Your 3 exercise days are complete fast days as you are zeroing out your intake through your exercise.

    The way you are approaching your weight loss will probably not give you the body, or results you are looking for.

    Cheers, h.

    @jtintx How long have you been on this plan and NOT losing weight? I think a lot of responders are not seeing that you said you aren't losing weight.

    Safe rate of loss is relative to current weight, amount to lose and safe caloric intake. So no, 1 to 2lbs per week is not one size fits all.

    And again, you calculation of 950 net per day on average isn't taking into account just day to day moving around. That also needs fuelled and will reduce your net further.

    No that was taken on my 50th birthday (2012 when I was an active MFP user)...almost 6 months to the day before my husband passed away. Since then I've gained 40 lbs. I'm an active user again so hopefully I'll get similar results.

    I've only been back on for two weeks. I lost 2.5 pounds the first week and only half a pound the second. So far this week I've gain a quarter pound. I know muscle burns calories so that's why I don't want to lose any. I lost quite a bit of muscle the first go round.

    That's true...unfortunately I'm pretty sedentary most of the day. I'm retired.

    What @VintageFeline says. Your math is off, you are in a much deeper deficit that you think and yes you are going to lose muscle, probably a significant amount. It cannot be any more clearly stated.

    That's basically what I've been doing without realizing it! I guess it's not such a bad thing after all. Thanks!

    You will lose muscle and without wanting to sound in any way rude, at your age you want to be doing every single thing you can to preserve it, it's all downhill for muscle loss and harder gains the older you get.

    And if you really want to retain as much muscle as possible, on top of eating more you really need to do some sort of strength training.

    Exactly (emphasis mine), that's why I was so concerned about the high exercise days. I'll try strength training but I'll probably whine about it the whole time. Honestly, I'm scared to eat more, especially since my appetite has been under control lately with the high protein I've been consuming. I want this weight gone. :smile:
