We are in super similar situations!! I am 28F, 5’ 3” and hit my highest weight of 232 a few months ago. I was always around 180 (before having babies) and hovered around 190 after having kids. I gained a lot since the beginning of 2020. I have been doing 16:8 for a few months along with 30 minutes of exercise (low intensity.. usually just walking or jogging) a day and I’m at 204 lbs now. I can’t wait to be back under 200. Good luck to you!!
Yeah. The 20+ will start making you crazy (or at least woozy) especially to start. I actually did a 25 today after a Saturday night party and late Sunday brunch nachos (my whole approach as a 54M is just that I don’t really need to eat more than once a day anymore). Keep up the fight!
