> it's difficult to keep yourself from getting back into unhealthy territory unless you're willing to spend your entire life counting calories and tracking weight religiously.

It depends on your habits. My habits are generally good enough that I don't need to count calories. Which is mostly luck, not an achievement of mine, btw.

> The last time I gained weight (from 68 kg to around 88 kg) I did it eating only healthy food in unhealthy amounts.

First, there isn't even clear consensus what's healthy and what isn't. But even if there was, I doubt you only ate healthy food. It is very hard to gain much fat eating a lot of vegetables and some fish and eggs.

Of course it's possible your diet is great. My experience with fat people has been that their diet was a whole lot worse than they claimed...
