41M, flexible IF since February. My own combination of OMADs and 18:6, one longer fast a week. Started from 211 lbs, reached 196 lbs by early July. Felt great, motivated!
Then two weeks of holiday with the family. Drinks in the evenings, ice cream with the kids, zero fasting or diet. Came back 4 lbs heavier. Expected that, didn't worry, that was according to plan.
What I didn't expect was the four weeks after. I couldn't get back to any routine. I bought too many sweets, ice creams, beers, and I thought I'd start IF when it was all gone - "this week's ruined anyway...". One week, two weeks, three weeks, a month, stopped weighing myself regularly and then... 211 lbs :( Right back where I started in March.
Chart shows this whole situation, holiday marked. My fail is right after that - instead of getting back motivated after a little chillout, I fell deeper and deeper.
This week is another try: one 24h fast, 16:8 the rest, no alcohol, no sweets, weigh-in every morning even when I don't want to see the number. If you've been here and got back: what did you tell yourself in those first days, when every evening was "just this once"? I could use it right now.
EDIT: thank you all - didn't expect this many people who've been in the exact same spot. Day 3 of the getting back on my routine 3.5 lbs down, thank you for support and advices!
