So, I know questions along these lines are asked a lot, and I've been searching and reading for several days, but I'm still confused about my current physical response to paleo. Sorry - this is kind of long, but I wanted to give as much info as possible.
I've been pretty strict paleo now for about 6 weeks. Occasionally less strict in social situations, but even then I try to eat as paleo as I can. I don't eat dairy (bar occasional milk in coffee, probably once a week). Prior to paleo I ate 'clean', but more grains (oats, quinoa, brown rice) and less protein and red meat and weekly treats (cake, ice-cream).
I'm 5ft 7in, female, 36, 137.5 lbs. I lost 2.5 lbs in the first week or so (water weight?), but nothing since then. My goal is to 'lean-out'/ lose 5lbs - I carry my weight around my hips and thighs - and to turn the flabby bits into muscle!
I'm counting calories and getting 1500 - 1600 a day and my nutrient ratios are around 10-20% carb, 30-35% protein, 50-55 % fat. I'm probably eating around 30-60 g carbs a day, 100-120g protein. I'm drinking plenty of water and taking a magnesium supplement. Diet is a good range of all types of meat and fish + veg, etc. I eat liver once a week. Physical activity is 2-3 Pilates classes a week, swimming once or twice a week (with a club, so quite intense), and I use a bicycle for transportation, but mostly short journeys.
My sleep has been much worse the last 6 weeks (sleeping lightly, waking up in the night, vivid dreams, waking up early feeling unrested). I've never had issues sleeping before. For the past week or so I've been feeling light-headed and weak. I rarely feel hungry now. This morning I woke up feeling really drained (and my heart was racing a bit), so today I've eaten a few more carbs (a banana before my Pilates class and then homemade parsnip soup as part of my post-class lunch). But that seems to have just given me a bit of a stomach ache (no prior digestive issues).
So, my question is - is this just the adaptation phase? Or the 'low-carb flu'? Or am I not eating enough calories (I've used lots of BMR calculators, which all give me different results, so I'm not sure exactly how many calories I should be aiming for to be in the correct amount of deficit to lose weight/ lean-out)? Should I add more carbs? (Although, I'm wary of upping carbs if that's going to make me feel more hungry and therefore harder to stick to calorie limit). Should I eat less protein and more fat??
Sorry for the long question, but any insight would be great. I love this way of eating, but I can't be doing with feeling so drained and out-of-it.
