Pregnancy weight gain so far?

Between week 10 and week 14 i gained a total of 4 kg.... my gynae said i gained too much weight... but i tot i was due to not having much appetite during the first trimester as i kept on vomitting and my appetite was better during 2nd trimester. Gynae said 1kg a week is too much and advised me to watch what i am eating and not to eat for 2. But to be honest, i didnt really eat a lot.
