The correct answer is that the metabolic requirement for increased caloric intake begins after the 13th week of pregnancy, which is into the second trimester.

During the first trimester, many women do not need to increase their caloric intake significantly. The energy demands during this time do not change substantially, and any additional calories typically focus more on proper nutrition rather than sheer calorie quantity.

After the first trimester, particularly around the 13th week, the body undergoes various physiological changes that accelerate metabolism and require additional energy to support fetal growth and development. Women generally are advised to increase their caloric intake by about 300 calories per day starting during the second trimester to support these increased needs.

Understanding this timeline is essential for personal trainers working with pregnant clients, as it allows them to tailor fitness and nutrition plans appropriately throughout the different stages of pregnancy.
