Trying to maintain.

I've not got to exercise very much last 3 weeks because of my arm (left Radial neck fracture), so no bicycle, weights, etc... Don't want to make my right arm stronger than my left (more than it already is, I'm right handed) and can't really hold onto weights. I've been walking and running 2-3 times a week, total time 1 1/2 to 2 hours each workout, slow, boring, and seems to last forever, but at least I'm getting a little physical activity. Plus a little ab work, though not a bunch.

 

Anyways, I'm using my fitness pal to track my intake and even though I've switched to maintain, I lost another .4 pounds this week. Started dieting (low carb, 50g or less and about 1950 calories per day for about 6 months before I started upping carbs and calories) August of 2013 at 295+ pounds (I'm 37, male, 6-0) and had not exercised for 20 years since high school. Shortly after starting my diet I started exercising 3-5 times a week (before my arm, I was doing 5 days a week, 3 weight days and 2 conditioning).

 

Anyways, I got to 165 pounds and ~10% (perhaps a little under, hard to tell with loose skin in lower abs, wish it would go away, but I'm leaner than I've ever been today) body fat couple weeks ago and decided to switch it up and maintain my current weight. Since then, I've lost about another pound (164.2 this morning) eating 2400 calories a day. Today, I adjusted my macros to 30% protein (was 35), 35% carb (was 30%), and 35% fats. However, don't know if this will help, though right now, I feel as though I'm getting enough protein (more than 1 g per pound of body weight) I don't know how low I should go with it. (180 G of protein is goal at 30%) Fat, I try to get 80 or so grams a day, and carbs, though I eat more than I use to, most of my carbs is fiberous vegatables. Though I do get cereal (Kashi Go Lean), sweet potatoes, bread, and little rice.

 

My plan is to maintain until my arm heals (Next monday will be 4 weeks, ortho said 6-8 weeks, though it is a lot better now and I can use for light stuff, I don't know how long it will be before I can lift heavy, I'm doing as told, to lift light and slowly build up to heavier weight, don't know how long that will take) and then I'd like to maybe start building some muscle (I'm skinny, LOL, I have abs for first time in my life though, and more time goes by the more they become visible, I can see them in any light--even lower part is there, once you look past skin) but I don't know if I need to up my calories more, keep going at current level and see if it stops or what. 2400 based off of lightly active on my fitness pal (though I could very well be "active" which would require more calories, I'm a welder but most days I'm up and down ladders, walking, carrying etc... Any thoughts?

 

Know, backwards from normal, I'm not losing weight questions, but I don't want to get too skinny. My original goal was to hit 8% (i'm really close I feel) but feel that it is time to put on some muscle before I get any leaner.
