The weight gain of pregnant mothers almost always exceeds the international standard of 25 pounds. Excess nutrition makes many pregnant mothers become \”sugar mommies\”. Ms. Zhou, 30, has had a good appetite since she became pregnant. Her appetite went from one bowl per meal to two and a half bowls per meal, and she often complained of being hungry. She had a check-up when she was 7 months pregnant and found that she had gained 35 pounds. The doctor reminded her to control her diet, but she didn\’t take it seriously. One month later, her weight had increased by 45 pounds.
