(I’m writing this because I always wanted to know what might happen if you cheat for a vacation, individual results may vary. I’m a male, considered obese by medical standards, but not in a crazy way, just in a love handles and beer gut way. I’m in very good health.)
Keto going off and back on:
I had been almost perfectly keto for 40 days prior to a vacation. I had gone from 191 down to 178.
I had good intentions of eating mostly Keto on an 11 day vacation back home. I even packed a “keto-kit” with my own frying pan/oils/powders/electolytes, etc. We left on a Thursday night, and did really good through Tuesday, then at dinner time on Tuesday, I pretty much let loose eating anything and everything that everyone else ate and drank. I did not drink sugared beverages until the drive back, since it was a long one, and I was kind of sick of coffee. I ended up having a Mt. Dew and a Monster Energy drink.
My weight at the house I was staying at was 179 when I got there, and 186 when I left.
Got home on Monday and just decided not to start up on the Keto regiment until Tuesday.
During the blow out, I ate a lot of Asian food with rice and noodles. French Fries in abundance, and a lot of craft beer and wine. I had a few bites of ice cream and even some cotton candy at the zoo. I had some fast food during the road trip, and pizza at the hotel. I did pretty much stick to skipping breakfast, except when we went out for a big one. My wife described my eating as “going off the rails”. My guess is that I had 3,000 calories per day, but I wasn’t counting.
At home weight (after the vacation, back to my home scale):
Tuesday a.m.: 185 (did a 21 hour fast until 4:30) Broke fast with dinner and some lite beers
Wednesday a.m.: 181 (again did 21 hour fast) Broke fast with 15 Buffalo Wild Wings, miller lite, veggies and tons of blue cheese.
Thursday a.m.: 180 (normal keto day with 2 BPFs)
Friday a.m.: 178 (back to starting weight)
How I felt when I started to eat carbs again: I was immediately bloated a bit and my eyes felt really tired all the time. I was rather drained of energy. Other than that, no issues that were alarming. I just hate that tired feeling.
How I felt as I went back to Keto once I got home: 1st day felt ok, did a 21 hour fast with only coffee.
2nd day felt ok most of the day
3rd day morning headache, keto flu variety
4th day morning headache, not too bad
I normally run 3 times per week, but did not do it on vacation, or when I got back for the first week, due to my running partner also being out of town. I’m glad I didn’t have to run.
In conclusion, I would do the exact same thing again. It made vacation a lot more enjoyable.
