I find that low-carb is better for me as keto has too much fat. Calories and fat are more of an issue for me now than they were when I was younger.

I'm on weight watchers and love it. I tried keto and my cholesterol went through the roof. I lose my weight slow but that's ok. I have lost 40 pounds in a year my daughter is on keto and she lost that much in a couple of months.

The ones I've used haven't been as reliable as a blood meter so I don't recommend using them.

It depends on your body size. One study shows that 1.6g of protein per kg of body weight per day (0.73g per pound) is the upper limit so you wouldn't want to go much, if any, beyond that.

With keto, you'll fill up on fat. Protein should be consumed in moderation. It does take some getting used to and it helps to track foods at first.

Doreen. From what I've read, too much protein may not be good for you. That's one reason why keto is a moderate protein diet. I have heard something similar about protein and calcium, but I don't know the specifics. I've been working with a local chiropractor to help me figure out what works best in my low-carb eating plan.

The maintenance plan depends on your age, weight, and sex. There are calculators that can give you a good estimate of the calories needed daily for weight maintenance. I find that eating less than 50-75 grams of total carbs works well for maintenance. I try not to eat too much fat as the calories seem to really impact me at my age so I follow more of a standard low-carb plan getting carbs mainly from veggies and fruit.
