I have been paleo for about 4 months, lost about 50 lbs, big improvements in athletic ability/strength/lean mass/etc. Lately my weight loss has greatly slowed though I have another 30-40 to lose. Not a big deal - I am patient and satisfied with my new paradigm of nutrition.
About 4-5 times in the past month or so I have noticed a real uptick in my metabolism and weight loss in response to a big dinner. So I will have maintained my weight for a week or so and then a particular dinner happens to be really big and I might even have a few sensible indulgences with it. The next day, my metabolism seems to be ramped up burning dinner off but going beyond.
I don't think I am under-eating - always get around 2000 cal range. Just curious if there is any reason this might happen? (it also may just be coincidence too). Could it be some sort of fast/feast interplay? I typically have smaller breakfasts because I am not terribly hungry in the morning.
