Low fetal weight gain

My baby’s weight dropped instead at week 34 (from 2.4kg to 2.1~2.2KG). Baby came out at 40.3 weeks 2.6KG. Healthy and low jaundice, no other conditions :) Gynae asked me to spam more calories to try and increase baby’s weight. I had 10-15 egg whites daily (hated eggs after that) and a lot of chicken breast as I didn’t wanna go with the junk foods. If gynae never raise any issues, then don’t worry too much.
