The first week drop is mostly water — what your numbers do next
That big week-one drop on Burnie feels like magic, but most of it is water and stored sugar, not fat. Weeks 2 and 3 slow down to the real fat rate, and that slowdown is the maths working, not failing.
Week one ends. You step on the scale. Down a couple of kilos. You feel amazing. You tell your family. You open Burnie and smile at the chart. Week two ends. Down only a little. Week three ends. Down a little more. The smile fades. You wonder, has my plan stopped working? No. Your numbers are doing exactly what maths says they should. The first week lied a little. The weeks after tell the truth. Here is what your numbers do next, and why.
Your body stores sugar and water together
Your body keeps about 500 grams of stored sugar. This stored sugar is called glycogen. About 100 to 120 grams sit in the liver. About 400 grams sit in the muscles. Each gram of this sugar holds on to three to four grams of water. So that stored sugar is really sugar plus a lot of water. When you eat less, the body uses up this sugar first. The water leaves with it. The scale drops fast in week one. But most of that fast drop is water, not fat. One doctor wrote it plainly: this water-heavy sugar store creates illusions of easy weight loss.
The slowdown in week 2 or 3 means my plan has stopped working.
mostly falsemostly false — explained simply
The slowdown does not mean your plan stopped. It means the water part is over. Water that leaves with sugar weighs a lot but carries no energy. Fat is different. One kilogram of body fat stores about 7700 kcal of energy. So real fat loss needs a real energy gap. On a sensible plan, that gap gives you about 0.5 to 1 kg of fat loss per week. That is the honest rate, and it is the rate that lasts. So weeks 2 and 3 are not failure. They are the first time the scale shows fat, not water.

The bottom line
Your first-week drop is mostly water leaving with stored sugar, not fat. From week two onwards, the scale slows to the real fat rate of about 0.5 to 1 kg per week. That slowdown is not failure. It is the first honest number. Add up your week's deficit in Burnie, divide by about 7700, and you will see your plan is still working. Stay in the slow weeks. That is where fat actually leaves.
