Dr Shannon Ritchey says some weight loss may come from muscle without strength training

What was said

"So we see that 25% of weight loss can come from muscle if you're not properly strength training. So there's an opportunity cost."

Dr Shannon Ritchey argues that people aiming for fat loss can over-prioritise cardio while neglecting strength training. She says that in a calorie deficit, weight loss can include muscle as well as fat, and claims that around 25% of lost weight may come from muscle if someone is not properly strength training.
