Some experts argue that the recommended weight gain for overweight women is especially high, saying that women who are overweight to start their pregnancy should aim to stay around 11 pounds weight gain for their entire pregnancy.
While there may be some argument for women who are overweight gaining less weight than women with a healthy BMI, the recommended weight gain at 22 weeks of 14 pounds, 17.5 pounds or 10.5 pounds for normal, underweight and overweight women, respectively is the standard and most widely accepted recommendation.
