If you go keto you'll need to refeed heavily on carbs 1 day a week. Otherwise you are asking for muscle loss. This is called a cyclical keto diet. A straight keto of no carbs over an extended period of time would only suit those who don't exercise.

Do you have any idea of the macro's and cals you are ingesting on the above plan?

The alternative is a low carb diet. You don't have to go crazy low, somewhere between 20-30%. Fats should be 20% with the remainder from protein.

I'd recommend an initial caloric intake of 2500 per day. This figure can always be adjusted depending on your gains/losses.

If you have some time have a quick look over some of this thread from somebody that initially used a 60/20/20 split.
