When working from home, i managed to lose on the order of 5-6 kg by eating less and skipping the occasional meal.
Now that the office is open again, the weight is slowly creeping upwards. This is due to the rather large plate served in the canteen at work.
To balance that out, my estimate is that the 45 km of biking a week i do, will have to be supplemented with gym visits 2-3 times a week.
With the above it will be possible to get within 4-5 kg of the ideal weight:

So maintaining a healthy weight is not easy without reducing servings and the ideal weight is even harder to achieve.
I tried switching to smaller plates. Doesn't seem to help too much.
I was finding that salads help. Not sure how much, though. I was basically in a starvation diet when it was working well.
That said, counting calories definitely helps better than I want it to.

Though, I am sympathetic to the idea that some foods encourage you to be more active. At least, some do the opposite. Eating a full pizza will almost certainly not be followed by anything active.
Oddly, following anything active with eating a pizza seems better.
