Fat Loss Is Driven by a Sustained Calorie Deficit
What causes fat loss?
Body fat comes down when you maintain a calorie deficit over time. That deficit determines how fast you lose weight, but pushing it too hard also raises fatigue, hunger, and the risk of losing lean mass. The best fat-loss plan is not the most aggressive one, but the one you can sustain while still training well.
Key Takeaway
Fat loss requires a sustained calorie deficit.
Actionable Tip
Use a moderate deficit you can sustain for weeks, not a crash diet you can barely survive.
