Another strategy I'm considering which would completely turn my eating world upside down, but would solve all my problems: I've for the longest time roughly been following IF because I don't eat breakfast, just coffee. But rather than skipping breakfast, what if I skipped dinner? Imagine I shut down my kitchen after 1pm or 2pm or something. All of my very worst eating and habits start after 6pm. I wouldn't drink. I wouldn't eat garbage. If I loaded up on a healthy breakfast and a regular lunch, and then didn't eat till breakfast the next morning, I would positively lose a ton of weight.
During quarantine there's no reason I can't do this. I wish I'd thought of it and started it 2 months ago. It'll be harder when "work life" kicks back in, including taking clients to dinners, and it being difficult to have a real/big breakfast and lunch during regular commuting work days. Then again, here in NY we're probably still months, maybe many months, from returning to that kind of normalcy. So maybe, just maybe, I can use this "upside down IF" for a few months to kick all the bad habits and get healthy.
