We’re in a similar boat!! I’m trying to lose about 20lbs by May as well! I’ve never seriously given IF a chance, so I’m excited to try it out!
Good luck with 20:4, I’m hoping to build up to that! And good luck on your journey!
Also coffee has always been my problem too. I don’t get sweet coffees but I get a lot of cappuccinos or lattes, and those calories add up for me. (A lot meaning I drink 2-4 a day 😬)
