Calorie Deficit Drives Fat Loss
What causes fat loss?
Fat loss happens when energy expenditure stays higher than energy intake over time. A larger deficit usually speeds up weight loss, but it also increases fatigue and makes muscle retention harder. For most people, consistency beats aggressiveness.
Key Takeaway
Fat loss requires a caloric deficit.
Actionable Tip
Use a moderate calorie deficit and keep lifting hard while dieting.
