I've been eating primarily paleo since last sept, sometimes more on the Mark Sisson end of the spectrum, sometimes more whole30-esque. I've lost about 40 lbs of fat, which was much needed. I no longer eat this way primarily for the weight loss, but it is a definite perk and I think contributes to my overall well-being.
A few times I have fallen off the wagon (typically on vacation) for a week or two -- I start out with a beer, then figure hey I've already had gluten, why not have a brownie?, then I think hey I'm in Key West I should have Key lime pie for gods sake, and then things spiral gradually out of control. I'm bad about working out on vacation too (I do crossfit 2x week at home), so that doesn't help. When this happens, I inevitably gain 5-8 lbs. I then snap out of it, clean up my diet, go back to the gym, and lose the 5-8 lbs in a week or two, an then continue on my overall downward trend of weight loss.
So my question: is this "bad" in some way? Is it yo-yo dieting thats f-ing up my metabolism? Or just some fluid fluctuation related to carbs? Is this a pattern I should try to break? I'm currently "recovering" from a Cape Cod vacation (hello fried seafood and salt water taffy and gelato!) and I found myself thinking "sure I'll gain a few pounds but I can drop it easily" making it that much easier to rationalize a nice glass of rum punch with dinner.
Thoughts, experience, suggestions appreciated!
