IMHO... I've done the keto and low carb thing in the past. A balanced diet with proper macros, micro nutrients and, in your case, a calorie deficit is a far better plan to get bf% down. Especially if you excercise regularly. I've had far more success with a moderate carb intake diet. 45%P, 30%C, 25%F. With ~500 calories deficit you will shed fat and keep your metabolism up and fiber intake healthy. GW will only expedite the process
