I do think it can be hard to figure out what to do though -- e.g. diet soda says 0 calories, but does it mess with your metabolism? (research is undecided). Personally I've done keto and found it less effort than working out every day. Some people don't understand that 10 chinups burns comparable calories to walking up the stairs. Also muscle weighs more than fat, so scales may be a fairly bad measurement.
That’s true. I remember being so surprised when I found out how few calories I burned running a mile! There are other reasons to exercise obviously, but it’s easy to overestimate how important it will be to weight loss for sure.
