I'm participating in a paleo challenge and lost about 4 lbs the first week but at the end of week 2 I've actually gained 3 lbs back! Very frustrating as I have not cheated at all: no grains, starches, alcohol, sugar (including artificial sweetener), dairy, soy or processed foods. I'm 5'3" and have been stuck at a plateau (145 - 147) for at least 6 months. I started doing Crossfit 3 weeks ago (approx 4 days a week) and the paleo challenge 2 weeks ago; thinking these changes would get me over the plateau hump!
I would really like to figure out what I'm doing wrong quickly. If I wasn't doing Paleo I would try to stick to approximately 1200 calories a day (more if I workout that day) at a ratio of 55% carbs/30% fat/15% protein. I know these ratios should be different on paleo but I don't know what it should look like. Am I eating too much fat now? Not enough protein? Too much carbs? (36% carbs/37% fat/27% protein).
Any and all advice is very much appreciated.
