Hmm. Thats rather dissapointing and suprising. I would think its easy to get lean on this diet and then just get your cals up and gain lots of muscle. Did you eat a lot of fruit? I personally believe to gain lots of muscle you need at least 250g of carbs a day.
I definitely wasn't eating 250g. Probably more near 100-150g. Although according to the research I've read, the muscle sparing effect of carbs and fat together is similar to if you'd carbs and protein only.
So for example if I ate 100g of carbs and 150g of fat it'd have the same results as 250g of carbs,
I'm not quite sure where I went wrong on the RPD though. Just felt like I couldn't get enough macronutrients in, or they just didn't work very well together. I ate a lot of fat and I just felt really gross, got fat really fast and then I got some ugly eczema on my neck which I've yet to get rid of.
If I had to guess, then I'd say where I went wrong was eating too much fat. The whole thing just never felt right really, fruit although great, just somehow didn't fit into the equation I think. I feel on primal everything fits perfectly together and I feel smashing.
