The Keto diet has been proven to raise a lot of heart risks if used for extended periods of time.

The military advises against its use, period.

I'm currently doing a bit of an experiment myself...I'd like to lose about 20 pounds but don't want to lose any muscle mass (actually want to put more on). A lot of new(er) research is pointing to protein--lots of protein--as not just the key to putting muscle on but also to helping burn fat. So, my primary dietary goal is 200g of protein a day. With my meal plan, that puts me right at 2024 calories/day (which is a 500ish calorie deficit). I lift weights every morning and do a 30 minute walk every evening on a 12% incline (treadmill, obviously).

I don't eat a lot of carbs but I don't avoid them.

Also, age is a killer. The way I'm currently working out...when doing similar training in my 20s/early 30s, I'd notice gains nearly immediately. Now, at much closer to 50...it takes months to notice much of anything at all. I want to go on HRT but my docs say no. I'm "high for my age."
