Why does weightlifting beat cardio for long-term fat loss?
Quick answer:
While cardio burns more immediate calories, weightlifting is the ultimate tool for fat loss because it prevents muscle loss, protects your resting metabolism from slowing down, and stops the brain triggers that make you overeat.
Why this matters:
When you diet without lifting weights, up to one-third of the weight you lose comes from your muscle tissue. This muscle loss slows down your daily calorie burn and causes โcollateral fatteningโ โ a state where your brain activates extreme hunger, forcing you to overeat and gain back all the fat (and often more) until your lost muscle is rebuilt.
FAQ:
Q: Can beginners build muscle while losing fat?
A: Absolutely. In a 5-month study, 85% of people who lifted weights while eating in a calorie deficit successfully built muscle while losing fat.
