Gaining muscle on a deficit

    Did I mention they are wrong?

    I know this topic has been done to death, but for those of us new to mfp it's a strange concept. The issue, I believe, is that we need to define a calorie "deficit" for this purpose. I'm thinking that a caloric deficit will allow us to lose weight, however, if we go below our bmr needs, that's the actual "deficit" we're talking about?

    For example, if my body requires 2,000 calories to maintain at my current weight and at my current activity level, and I drop to 1,000 cals, that's below my necessary bmr, that which my body needs to function properly. So in this case, I'm guessing my body won't make muscle because it's using everything it needs to function.

    If I up the calories to 1300, which might be my bmr + 100 extra cals, then I could build muscle with that additional 100 cals. Is this too simple an analysis or do I have it right?

    Thx for revisiting this; I get that you've done it again and again and appreciate your patience.

    The calories would need to exceed your TDEE (total daily energy expenditure). If not, then you're still in calorie deficit.

    I think you may be confusing BMR with TDEE

    Think of muscle as a relatively expensive commodity. If you have a deficit that is below your BMR, you are correct in your assessment that your body is using every calorie and every bit of fat just to function. You essentially do not have enough "currency" to even maintain that expensive commodity called muscle, so your body will burn more of it off in an effort to be more efficient.

    If you need 2000 calories to maintain your body weight and have a reasonable deficit of calories to lose weight, but not so drastic as to be below your BMR...and you get adequate protein and do resistance training, you essentially have enough "currency" and savings (fat stores) to maintain a high level of bodily function, provide energy for light to moderate intensity workouts, and maintain LBM, including muscle....where the bulk of those calories for maintenance of muscle will go towards repair...there really won't be enough currency to purchase more muscle (i.e. gain muscle).

    Now, if you eat at a surplus of calories and you are working out and lifting weights, etc...you have enough currency to provide for a high level of body operation, including moderate to high intensity workouts, putting up more weight, running faster and longer, etc. You have more than ample currency for muscle repair, so excess currency actually goes towards the purchase of more muscle. Be careful though...too much excess also leads to increased fat stores along with that muscle.

    Hope that makes sense.

    Excellent post/explanation.

    This is a great thread. One of the best ones I've seen on this forum.

    There's a whole bunch of people saying you can't gain muscle on a calorie deficit. Okay, well, I don't have enough knowledge to dispute that, but I do note that I'm setting 10-year powerlifting personal bests on a 1k+ calorie deficit right now. I have no idea how much of that comes from just getting back in training versus from muscle versus from the development of neuromuscular coordination.

    What I do know is at the rate I'm losing weight I'll be cutting until October before I start trying to build a calorie surplus. Then I'll have a very different problem: With a 4,200- 4,400 calorie TDEE, how the hell do I eat 5,000 calories a day in a balanced, healthy way? I have no idea.

    On my first chest day back in September when I started this journey, I could only do 90 lbs on bench to get 3 sets of 8. Now I am working out with 165-175, and did a 1rm of 195 this week, which is a new personal record. Going for 200 next week. However, I have put on NO muscle, as I have been in a calorie deficit this whole time.
