I'm 23,female, 5.7 and 67kg. I've been Paleo for over a month now and have fully changed my lifestyle. For the first 3 weeks I was unaware I was dramatically under-eating (because I was seemingly eating far more than before). For the first 2 weeks everything was going brilliantly - heavy lifting at the gym 3 times a week 30mins a session, getting early nights, walking lots etc the usual. HOWEVER, I took upon eating 2 meals a day; breakfast and dinner, thinking these were large enough to keep me going (later found out I was only consuming roughly 800 calories of Protein/fat a day and to make things worse I was pretty much constantly IF in hope of leaning down quicker). Everyday was in the less than 20g of carbs with no starchy vegetables, fruit etc. After a while I started having extremely awful sleeping patterns, insulin spikes and raised cortisol- taking ages to get to sleep, heart racing, waking up in the middle of the night, brain won't switch off, can't get back to sleep - the cycle begins.
After realising the error of my ways, and a lot more research, I changed things around. Things have been better since I've dramatically increased my calorie intake (lots more protein + fat and no IF), I also began adding in a sweet potato post workout to replace muscle glycogen and have decreased training from 3 to 2 times a week.
My sleep is better, however I am consistently waking at least once during the night to go to the toilet (no I'm not drinking excess water) and then I will struggle for about 1-2hours to get back to sleep with my mind racing. Sometimes I just wake up in the middle of the night thinking and it's killing me that I can't just switch off. Just to add to it there has been no reduction in body fat after 5 weeks and it is now becoming a viscous cycle of stress getting in the way of weight loss.
Sorry - a very detailed question but any thoughts would be much appreciated!
