>I want to start fasting to dig into the body fat but how are you supposed to do that without sacrificing muscle
you don't lose significant amounts of muscle while fasting if you're overweight or obese
Your body has a remarkable ability to protect your lean body weight and prevent muscle loss during fasts. If you're doing short fasts (3-7 days at most) you will regain pretty much all of the muscle immediately after your fast, provided you eat enough protein and aren't already considerably lean (~18% bf and under)
Do cardio while fasting, don't do any heavy lifting if you're going past 3 days, and make sure that your meals during the first few refeeding days are extremely heavy in protein.
