Fats can also have high satiety which might make some people eat less.
I think that is part of what happened to me. My blood sugar levels were going up, despite no changes in diet or medication. I wanted to see how much dietary carb levels were affecting that, and decided to try lowering carbs. Nothing radical--just lowering from the 50-60% calories from carbs that is typical to around 40% [1].
I did not attempt to cut calories during this. In fact I did things that would increase calories of some items. E.g., if I was getting a sandwich (50% calories from carbs) I'd order it with mayo or extra cheese or extra meat to get the percent from carbs <= 40%.
Blood sugar did come down, but to my surprise so did weight. It turned out I was eating something like 30% fewer calories, because I wasn't hungry enough for more.
[1] I picked 40% because it is easy to calculate. If something is N calories, it is 40% from carbs if it has N/10 g of carbs. That makes it easy to keep a running total throughout the day of how many grams over or under you are from 40%.
I ate a diet where 80% of my calories were from fat and I struggled to eat more than 1300 calories in a day. I think unless you’re eating cheesecake every day (hyperpalatable foods where carbs + fat calories are near a 1:1 ratio) you’re not going to gain weight eating fat.
