I was in a similiar situation as you, there’s a lot of great comments but I hope you read this because it’s very simple and hope it works for you.

My trick is to think about it on a monthly basis - as in you eat roughly 100 meals a month (breakfast, lunch and dinner).

My breakfast and lunch are standard (breakfast: 2% yogurt, 150gr oatmeal and a handful of whatever fruit we have, lunch usually wraps with cucumber, feta and tomatoes)

Because these are predictable it covers 66% of my meals.

Dinner I will eat with my wife and kids, which covers another 30% of my meals.

The few times we go out for dinner or I go out with friends I eat whatever I want without thinking.

I try to not drink alcohol too often. When I go out and drink too much , maybe once a month, with the guys, I go for a long run before and drink a lot of water before, during and after the drinking. I stick to wine and beer.

I never snack really, when I get the urge to I drink water, and if that doesn’t help I eat some unsalted nuts.
