Gained about 5lbs in 20 days of no weights. Got a bit of a roll around my lower waist.
I did do some swimming and calisthenics, but generally just relaxed and I enjoyed my holiday with my family. My plan to "holiday-proof" my body was a bastard IF/CBL plan, I fasted until noon and tried to stick to a 8-10 hour window and eat ULC, or at least eat carbs only at night (desserts and fruits galore!). Fortunately, most parties here have roasted or fried animals, so it wasn't too hard.
One thing I forgot to plan for was nuts. I have terrible portion control with nuts, and my parents had walnuts, almonds, pistachios around the house. Needless to say, I probably ate 300+ calories worth of nuts a day.
Tested my strength, so far it's been maintained.
Did a 7 day recalibration right after New Years day and got right back into weightlifting... finally my humble 4-pack abs are almost back
