Wow I feel for you, they've really not been very kind or informative to you, I would look for another doctor.
I don't know much about being pregnant or having babies, but your 4kg increase in 4 days will most likely not be due to putting on fat, or excess sugar. It will be a combination of fluid retention, and the fact that your baby is growing and getting heavier. Fluid retention is when your body starts holding onto water. It happens to a lot of women during pregnancy, so looks like they have gained a lot of weight, when really they are just storing water.
