That was actually a very good read Jeanette, thank you.
And I do want to clarify, because after reading back thru the thread I don't think my initial comment was as well put as it could have been.
My main point was that it is not easy, and some would say near impossible, to put on muscle long term in a calorie deficit.
And as Jeanette article stated, even if were one to do such a thing, even in a long term capacity, its probably not going to be accidental.
And I have still yet to find an article that shows muscle gain in a calorie deficit long term in people not doing large amounts of strength training and on specific nutritional diets to promote the muscle gain.
So, to summarize: People do not tend to gain muscle long term on a calorie deficit by accident.
That was all.
