Before pregnancy it is ideal to start a balanced diet plan to organize our routine. If you haven’t started it don’t worry, it's never too late to start. Your baby will appreciate a balanced diet because it will completely help in their healthy development. This does not mean you should eat for two or eat twice. What you should do is increase the amount of nutrients consumed. The energy requirements only increase by 300 calories a day during the 2nd and 3rd trimester. Do not stress if you increase fat storage. It is necessary for childbirth and lactation. The weight should not be a problem during pregnancy; instead it favors the baby for childbirth preparation. Women who do not gain weight are at risk of developing complications.
