If you lost weight you have burned more calories than you consumed. The other way unfortunately does not work.
Sometimes you restrict calorie intake, you feel ill, your body adapts and starts burning less with other repercussions.
If you want to lose fat you must restrict calories but also provide enough time for your body to use the stored fat, and it can not be used while the insulin levels are high. This is the reason that both IF and keto “work” (if calories are also somewhat restricted).
Ofcourse if you eat 1 meal a day it is more likely that you will consume less calories tahn eating 5 times a day (IF), also if you do keto you will not eat sugars (or other carbs) and again it is very likely this will lead to consuming less calories than otherwise.
A normal, safe level of calorie restriction in the range of 500 kcal/day will not cause your body to burn significantly less. However as you lose weight your resting metabolic rate will decline just because you have less tissue to keep alive and that takes less energy.
