The amount of body fat you have is really not relevant - if you have any fat to burn, and you always do, your body will burn it when it needs energy. So if you're lacking energy, for some reason your body isn't able to access the fats it needs.
Further to what Turgon said above, if you're still stimulating too much insulin release through excessive carb and protein consumption, you may have difficulty getting into fat burning mode when you need it for physical exercise. Insulin prevents fat burning.
I would lay off the fruit and maybe replace it with non-starchy vegetable (green beans, kale, sauerkraut, salads, that sort of thing) so that your insulin isn't rising sharply to meet with the demands sugars make on the body, (natural fruit sugars or otherwise). I would also start restricting protein more and INCREASE THE FAT.
I was going through similar issues when I switched over to an all meat diet, and it was simply because I was eating too much protein (and probably not enough fat). It pays to weigh out how much protein you're eating so you have an accurate idea of what you're consuming. I know it seems like a pain to be measuring things at meals, but if you're suffering from these symptoms, it's likely you're still doing too much protein/carb which is causing too much insulin release and preventing fat burning.
You could also try adding L-Carnitine as a supplement. It helps to get the fats into the mitochondria to be burned for energy.
Hope this helps :)
Thanks for the info dugdeep. Although I am on a strict ketogenic diet, I have been losing some weight lately and I can't seem to figure out why given that until recently my weight was pretty stable at around 62Kg while I'm now at 55Kg. I'm not sure if my weight loss is due to eating too little protein, fat or both?. My body fat went down by less than 1% so I'm worried that I may be losing lean tissue. I do keep to the 1.0 grams of protein per Kg of body mass and eat plenty of fat. I also do two very short resistance training sessions per day (10-15 mins in the morning and afternoon) and I do feel a lack of energy compared to how I felt before losing weight. At this point I'm really unsure as to whether I'm not eating enough protein or if I'm eating slightly too much which prevents my body from burning fat? (I'm not really putting up any fat though).
Also, does eating too much or too little fat affect your muscle mass when in ketosis, or is that just related to protein consumption?
