One thing people miss out: at home, I have complete control over portion sizes.

I tend to end up overeating at restaurants because the portions are bigger.

At home, I can only serve as much as I want and keep the rest in the fridge.

In theory, I can - and do - do that at restaurants as well, but somehow, the restaurant environment promotes eating more. If I have four bites left, I might hesitate to ask for a takeaway box. But in the house, I can just throw that into a tupperware and pop it in the fridge
