What is the recommended daily calorie intake for pregnant and lactating women?

The nutritional needs of women during pregnancy and lactation increase compared to those who are not pregnant or lactating. As mentioned in the previous table, calories are calculated or estimated especially in the last six months of pregnancy. Thus, according to mathematical calculations, the calories required during the last six months of pregnancy and during breastfeeding are equivalent to those needed before pregnancy.

What is the recommended calorie intake for bodybuilders?

During the bulk phase, calories should be increased by 15%. Muscle growth occurs during this phase. The phase of reducing excess body fat is caused by the phase of muscle strengthening through the gradual reduction of calories consumed and the increase of aerobic exercises, so daily calories are reduced by 15% when transitioning from the muscle building phase to cutting phase. Consult a nutritionist at least once a month to adjust your calorie intake.

In 2004, a review published in the Journal of Sports Medicine concluded that a diet should contain 55-60% carbohydrates and 25-30% protein for both of the former phases.
