Weight Loss FAQ

How much weight can I lose in a week?

A safe rate is 0.5% to 1% of your body weight per week. For most people, that's 0.5kg to 1kg (1-2 lbs). Losing faster often means you are losing water weight and muscle tissue, not just fat.

Is "Starvation Mode" real?

It involves metabolic adaptation, where your body burns slightly fewer calories as you lose weight. However, it will never stop weight loss completely if you are in a true deficit. It's often exaggerated online.

What is the best exercise for fat loss?

The one you enjoy and do consistently. However, a combination of Resistance Training (to keep muscle) and Zone 2 Cardio (to burn calories directly) is biologically optimal.
