Week one of a diet is a lie, and so is the week you come back from holiday.

Why week one is dramatic
Cutting carbohydrate depletes muscle and liver glycogen, and each gram of glycogen is stored with roughly three grams of water. A few kilos can disappear in five days with only a fraction of it being fat. It feels excellent and it is mostly plumbing.
Why week three feels like failure
Once glycogen stabilises, the scale reflects actual fat loss — which at a sensible rate is a few hundred grams a week. People who anchored expectations to week one conclude the diet has stopped working, and quit at precisely the point it started.

Get SodaSlim — From $49What else moves water
Sodium intake, carbohydrate load, menstrual cycle phase, air travel, poor sleep, alcohol, hard training producing inflammation, and creatine supplementation all shift fluid independently of fat. A two-kilo overnight jump is water. Fat does not accumulate that fast.
The practical response
Use a seven-day rolling average, add a weekly waist measurement, and judge over months. This applies to any routine, supplement included — which is why SodaSlim is sensibly assessed at the 60 to 90 day mark rather than after a fortnight.
