I had put on some pounds so started going to the gym, worked really hard to burn calories, I was starting to look good, then covid hit. I tried going a couple of times when they opened again but nobody was doing the sanitizing/mask wearing they required, so I stopped. I'm still somewhat active but not to the degree I was before and the weight was creeping back on. Finally, out of desperation, I decided to start skipping breakfast. It worked. My weight has actually dropped quite a bit in the last few months and I don't have to lift weights or run on a treadmill forever to do it. I'll go back to the gym again when it's safer but I'm surprised how effective just missing a small meal can be.
