HUMAN NUTRITION

Detailed explanation-1: -For most normal-weight pregnant women, the right amount of calories is: About 1, 800 calories per day during the first trimester. About 2, 200 calories per day during the second trimester. About 2, 400 calories per day during the third trimester.

Detailed explanation-2: -As recommended by the Academy of Nutrition and Dietetics, the first trimester does not require consumption of any additional calories above a woman’s baseline calculated needs. It is recommended that she consume an additional 340 calories in the second trimester, and 450 additional calories during the third trimester.

Detailed explanation-3: -First trimester: You probably won’t need any additional calories during your first trimester. Instead, you should focus on choosing nutritious foods that keep your energy up (and, if you have morning sickness, don’t make you nauseous!) while supporting your baby’s development.

Detailed explanation-4: -In general, the first trimester (or first three months) does not require any extra calories. Typically, women who begin pregnancy overweight need an additional 200-400 calories per day during the second trimester (second three months) and an additional 400 calories per day during the third (last) trimester.
