I eat between 150-250 grams of protein a day, the bulk is definitely from meat and fish, the rest dairy/eggs, nuts and nut butter, fruit/berries, veg/avocado, tubers, etc. I'm starting to play with whey protein shakes now as well just to see how it works as an additional source.

I only had side effects when I ate lower than this. I was tired, stopped building muscle, and just overall did not feel "right" if that makes any sense? I played around with fats, proteins, etc. and this ratio of protein has done me up well and I feel good. I burn through my food fuel really quickly so upping the protein, upping the fat a bit more, and it's been aces. I've steadily gained muscle but remained nice and lean.

If it helps, I CrossFit and lift heavy 3-4 days a week, cycle maybe 30-miles a week (down from 100+), and have started Bikram 1-day a week.

Anything over 1g/lb of bodyweight is a waste for the most part according to the majority of studies, ultimately you have to expirement though to see what works for you. I typically eat 150+ but that's because I weigh 170.

If you don't feel like your recovering right or making the gains you want maybe try upping it a tad, as long as you don't go over 250 I think you should be fine as far as excess protien goes but not too sure on that one.

I heard it's only (red) meat that creates ammonia,not sure if it's true. So,you could probably eat more eggs,fish,poultry?...not sure about game meats. Dairy,if you do dairy.

High protein is hard to avoid on the Paleo diet. You really have try to find paleo carbs and fat, because protein is such a readily available food for us. When I was eating tons of protein from meat, I was getting hives across my body when I would get nervous or workout. Once I laid off protein, this never happened.

From my experience as a type 1 diabetic, you can only eat so much protein and then the rest your body converts to glucose. If I over consume protein I end up with a higher blood glucose level later. I've tested this my eating strictly protein for breakfast and then looking at blood glucose levels before and after. I chose breakfast because I've generally fasted for an extended period of time prior. I'm not a scientist so maybe someone can help me explain the biochemistry behind this.
