You’ve probably seen headlines like this online:
“Lose 5.5 kg (12 lbs) in 3 days with this one drink!”
“Doctors hate this secret fat-melting tonic!”
These claims are not just exaggerated—they’re misleading, potentially dangerous, and not supported by science. Let’s break down what’s really happening—and what’s safe.
⚠️ Why “5.5 kg in 3 Days” Is a Red Flag
- Healthy fat loss is about 0.5–1 kg (1–2 lbs) per week.
- Losing 5.5 kg in 3 days is almost entirely water weight, glycogen, and gut content—not fat.
- Such rapid loss often comes from severe calorie restriction, diuretics, or laxative effects—which can cause:
- Dehydration
- Electrolyte imbalances
- Muscle loss
- Slowed metabolism
- Gallstones or nutrient deficiencies
🩺 Medical consensus: Rapid weight loss like this is not sustainable and can harm your health.
