The biggest thing that helped me lose weight was subscribing to a meal delivery service and sticking to it (drink water if you need to feel more full and avoid the desire to eat more). Outsourcing my food choices to someone else made it substantially easier to avoid consuming more and unhealthier calories because of the enjoyment of putting things in my mouth or the challenge of controlling portion sizes. I grew up in a home where we had to finish all the food on our plate, and that combined with the the absurdly large portion sizes that you get at almost all restaurants in the United States presents a significant obstacle to weight control.

That's the hack that worked best for me, but I wouldn't say its a "weird tip". It really boils down to the following three factors which really all need to be present.

1. Exercise - You have to demand things of your body so it will send energy to rebuilding rather than conservation.

2. Calorie intake - You have to consume fewer calories than your body is demanding.

3. Food quality - Eat mostly whole foods and low glycemic index carbs that are less calorie dense.

Many people tend to focus on just one of those three things, and while that can work, doing all of them is far more effective. I tend to think that the "weird trick" mentality is a significant obstacle to success (in this as well as many other areas of life). The one weird trick is that hard work is the path to accomplishing things.
