I was just thinking and wondering about it.
Earlier in my life i ate a lot of snacks and drank soda. Ate way more and way more unhealthy and didn't do any sports but never got heavier than 78kg. Now i live way healthier. I eat healthy, eat less, do sports and have about 70kg. But if i was to quit sports and get back into my old eating habits I would put up 3-4kg in a month i'm sure of it.
But why wouldn't I get fatter after a certain point(78kg for me)?
If I take more kcal in than I put out, shouldn't I theretically gain those 3-4 pounds every month as long as i continue to live like that and soon reach the hundrets?
