The sick week — why the scale lies when you have a cold or fever
When you fall sick the scale often drops fast, then climbs back when you recover. Most of that dip is water and missed food, not fat — so do not celebrate it, and do not panic at the rebound.
On Wednesday Priya's throat felt like sandpaper. By Thursday she had a fever and stayed in bed. She ate almost nothing for two days — just sips of dal and a glass of nimbu-pani. On Saturday morning she stepped on the scale. It said 2 kilos less. She almost danced. By the next Saturday, those same 2 kilos were back. She almost cried. Both feelings were tricks. This short read is the story of the sick week — why the scale fibs when you are unwell, and how to read it without a party or a panic.
Why the scale drops when you are sick
Your body is mostly water, and it carries the food you ate as it digests. Take away the water, or empty the food pipe, and the scale falls. A fever makes you sweat more and breathe faster, so you leak water you cannot even see. When you are unwell you also eat less — less dal, less roti, less chai. Less food inside you means less weight on the scale. MedlinePlus, the US National Library of Medicine's page for everyone, lists fever as a major cause of fluid loss, and notes that when you are sick you often do not feel like eating or drinking. So most of the sick-week drop is water and missed food, not fat.
I lost 2 kilos during my fever, so I burned 2 kilos of fat.

Fat loss is slow maths. To lose real fat your body needs a calorie gap stacked over many days, not a three-day fever. What vanished in the sick week is mostly water leaving through sweat and breath, and less food sitting inside your gut. Think of it this way. Drink one big glass of water — it has real weight, and the scale sees it. Eat two rotis — they have real weight inside your tummy, before a single calorie is burned. When you stop eating and start sweating, of course the scale falls. And when you recover, sip chai, and eat khichdi again, the water returns, the food returns, and the scale climbs. That climb is not failure. It is just maths settling back to normal. As MedlinePlus puts it, dehydration occurs when your body does not have as much water and fluids as it needs — and it fixes itself when you drink and eat again.

The bottom line
During a sick week the scale mostly measures water and missed meals — not fat. So no party when it drops, and no panic when it climbs back. Log the weight, write 'sick' next to it, sip your water, eat your khichdi, and read the trend a week after you recover. Burnie is your honest notebook through the fever, not the judge of it.
