What would happen if I ate maintenance calories(no cutting/no bulking), healthy diet, and did 3 days of lifting and 3 days of cardio.

Would I slowly turn body fat into muscle?

I am finally at the weight I want, but still have a little more body fat than I'd like. I am just starting to see the abs, but I'd like more definition. I don't really want to lose anymore scale weight though.

I'm a little perplexed...

It depends on what your training looks like now? What your diet macronutrients look like now? How well your body has responded to the changes so far?

Sorry, it all depends

No, This is physically impossible. You can not turn fat into muscle or muscle into fat.

You read my mind.

say a trainee began to workout for the first time. he is 150lbs, 21 years old. finished growing. he trains for strength over a long period of time. lets say 5 years. he makes huge progress and he is really strong now. the thing is, he ate maintenance calories the whole 5 years. he is still 150lbs.

so will his body have gained any mass? how would it if he didnt give it food to grow? i can imagine that he would look different! would his body have cahnged?!

"No, This is physically impossible. You can not turn fat into muscle or muscle into fat."

I guess I didn't mean that literally. I meant to ask if I'd gradually burn body fat by eating maintenance calories (eating a good diet and working out) while at the same time building muscle. Or do I need some deficit(say 200 cal) in order to lose body fat? I've been cutting (500 cal deficit) for a long time and I'm not sure if I should continue or increase the calories.

Maintenance calories would mean enough calories to maintain one's weight. A calorie deficit is require for fat loss, and a calorie surplus is required for muscle growth. (So you won't be able to do both at the same time, UNLESS you're an absolute beginner.)

YES....this is possible. However, its abysmally slow. In the '5 year' example above, you might gain 10 lbs of muscle IF you're lucky. Meanwhile those who bulk and cut, gain that much (or more) per year.

Thanks for the input. I'll continue to cut until I see get the abs, then I'll bulk.
