How People “Lose” 5.5 kg (12 lbs) in 3 Days — And Why It’s Dangerous
You’ve seen the headlines:
“Drop 12 pounds in 3 days!”
“Flush out fat fast!”
“The celebrity detox that melts weight overnight!”
It sounds like magic.
But here’s the truth:
No one loses 5.5 kg (12 lbs) of body fat in three days.
That’s physically impossible.
What they’re losing is mostly water weight, not fat — and the methods used can be dangerous.
Health professionals from the Mayo Clinic to the American Heart Association warn against extreme short-term weight loss because it can lead to:
Buy vitamins and supplements
- Severe dehydration
- Electrolyte imbalances
- Muscle loss
- Heart strain
- Gallstones
- Nutrient deficiencies
Let’s break down how this kind of rapid drop happens, why it’s misleading, and what safe weight loss really looks like.
