Also when you eat a lot of excess carbs, your body stores it as glycogen in your liver and muscles. This causes an increase in weight due to water retention associated with it. One reason we lose so much weight in Phase I is due to using up that stored glycogen and the associated water with it.
This explains it:
Firstly, glycogen storage is associated with a concomitant storage of water. It is estimated that every gram of glycogen stored is associated with about 2.7g of water.
and this:
Carbohydrate (stored in your muscles and liver as glycogen) is accompanied by a good bit of water. For every gram of glycogen stored, you store anywhere from 3-4 grams of water with it.
So if you weigh yourself after a splurge or binge, the resulting weight is not accurate. Also there's the weight of the extra food in your gut before it's eliminated. I never weigh myself after an off plan day, or if you do, don't sweat it so much.
