So I'm also confused about this because for the past few weeks, I've been eating up to like 2000 calories (& hating myself for it) but burning 2500 so I'm still maintaining a deficit. Buut I'm NOT. LOSING. WEIGHT.
Granted, I STILL binge with large amounts of food but I am also trying to get out of a binge mindset. But honestly I feel like it's the food weighing me down & not budging the scale. I always lose more weight when I stick to a ~1200 cal plan without exercise.
It's just confusing because it could be food weight or muscle weight (I do mostly LISS, HIIT, and a bit of strength training) but it's been soo so so frustrating and has actually led to the most recent binge cycle I've been in.
So I guess my point is, it is probably better for you to eat higher cal on your higher cardio days, as long as you can control not binging. You might not notice fast results, but getting out of your binge cycle is most important, and then after you get used to it you could maybe start not eating back your exercise calories and see what that does.
Good luuuuck! <3
