Read in multiple places over the years including here. Perhaps that is someone who is already low bf and has been lifting awhile.
it must be true that I’ve done both because me at 115.3 kg is now fitting into 36 waisted jeans which didn’t happen last time I was this weight.
Yes if you have a decent amount of fat to lose still and aren’t in a huge deficit and are able to keep training at a sufficient intensity and volume, muscle gain should be occurring as you still have a decent amount of accessible energy available to compensate for the lack of energy from food.
Realistically nobody ever recomps into infinity though - otherwise you’d see people getting stage lean and growing whilst eating at maintenance.
The whole point of dieting is to get to a bf level you’re happy with, then either you sit at maintenance forever eking out efficiency gains with what muscle you have and get a bit stronger over time - which is fine and what many people do - or if your goal is to try and aim towards whatever natural limit of fat-free mass you can carry is, you have to be in some form of surplus long enough (and training intelligently enough to progress in your lifts cos linear progression stops working pretty quickly) to grow the new tissue required, some of which will always be fat.
What happens to many people - me included in the past - with that latter goal is they diet down, look all beach body and happy but want to be bigger, but then are scared to gain weight again and consequently their lifts plateau (easier to train harder when there’s plenty of food), and they don’t fill out their frame to the extent they could. When you’re more advanced in your lifting age then the rates of muscle gain are so minuscule that sitting around maintenance is more of a viable strategy but when you’re still capable of growing kgs of muscle it just hinders your progress.
You don’t actually need that much of a surplus to maximise muscle growth rates, but since you never really know exactly what your maint. calories are each day or if you’re actually eating that much, it’s easy to never end up being in a minor surplus at all and consequently you spin your wheels and get nowhere.
Anyway keep up the good work!
I plateaued, I was losing ounces per week, if that, and when I stepped up my exercise and ate more, I stopped counting calories and ate more food even when I wasn't exercising.
I could have shed a ton of fat faster, but want to keep this going, so....
