Is it true that ... muscle turns into fat if you stop working out?

If you take a break from the gym you may lose muscle and gain fat, but it isn’t as simple as one turning into the other

Is it true that ... muscle turns into fat if you stop working out?

TL;DR

  • Muscle does not biochemically turn into fat, nor vice versa.
  • Stopping exercise can lead to a loss of muscle mass.
  • If calorie intake isn't adjusted during a break, an energy surplus can lead to fat gain.
  • The combination of muscle loss and fat gain can falsely suggest one tissue becomes the other.
  • Staying active during a break results in fewer changes than complete immobilization.
  • Maintaining high protein intake and slightly reducing calories is recommended during exercise breaks.
