Lol, this happens. 95% of all restaurants will introduce carbs and sneak them in. Unfortunately, if you want the full effects, it’s best to keep a 7 day period from your last carb nite, accident or not. It’s okay even if you did a 14 day low carb period, you won’t suffer from it.
Think about this, what if you continue these carb nite accidents, then you’re not really on a diet.. right? Just try to be very mindful next time you decide to eat out. Restaurants don’t do a good job with low carb foods, and a lot of them don’t taste that good. What I do, is just get a drink of unsweetened ice tea, or a diet coke, and sip very very slowly. I also get wings (plain) with the bone.. or a dry salad with no croutons… and eat that slow.
