You lost ten kilos in six weeks! I think it's not likely you're going to feel fantastic when you're so very calorically out of balance. Pick a goal. If your goal is to continue to lose weight (hopefully at a slower rate), I'd back off on the exercise. You don't want your body to actually think you're starving, because that's really bad. Once you're ready to take a break from losing weight for a while, then you can properly fuel your exercise so you are able to work. Alternating between periods of losing weight and fitness might be a reasonable approach. Trying to do both at the same time may be too much.

Hey Tony,

It's probably best to throw up some form of a food and exercise journal.

It could be the balance of your diet or it could be that you're over training.

Here is an example of a similar and more detailed question. There are also some answers there that might be useful. 2 weeks on paleo and I still feel like crap.

Keep tweeking it. You'll find a balance that works for you.

i think its time for a carb refeed friend!, do it every couple of weeks.

This is common when people go paleo , due to the fact they take peoples dogma as gospel ! I really recommend u look @www.leangains.com this is an awesome approach to eating and yes it can be done in a Paleo approach as well which i do myself . Many people when going Paleo always go to ketosis ketosis makez people feel like str8 s**t !! It's good if u don't train ur body but anyone who trains the body , especially extremely needs carbs and needs them in abundance .
