Hi and welcome.

First off, this is a great eating plan to do when endurance training. I trained for a marathon 5 years ago whilst on this diet, although I was in OWL, so eating more (healthy) carbs and a lot of food in general to keep energy levels up. At peak fitness training, I was eating every 2 hours. I found that downing egg whites (raw) were a fast and easy way to get protein when I was on the run -- literally.

As far as building mass, you will find that serious body builders eat a low carb/very high protein diet anyway. A good buddy of mine was training for the World Amateur Bodybuilding Championships and he swore by grilled chicken or turkey breast and egg whites, usually raw but not always. Lived on this for weeks and was ripped all over. He believes a lower fat, high protein, low carb diet is the best food plan for building lean muscle mass and I tend to agree.

Finally, as you are at a healthy weight and physically active, I think you are fine to start at pre-maintenance. I wouldn't shoot for ketosis at all. Just eat a lower carb diet full of fresh and locally sourced foods.

Congrats on the weight loss and good luck!
