The BMR equation for females takes this into account, that’s why it multiplies height and weight by smaller values. Women often have less lean body mass than men, so they will generally have lower BMRs. Nourishing an infant as it grows (and, later, producing breast milk) requires extra energy from the body - if you've ever noticed a woman's appetite increase when she becomes pregnant, you've seen this effect in action. Women who are pregnant (or breastfeeding) will have higher BMRs than women who are not. However, women are unique in that pregnancy can also significantly impact BMR. Springer International Publishing Switzerland.Just like in men, the Basal Metabolic Rate varies greatly among women based on height and weight.įor an accurate BMR measurement, get right values for your height and weight.ĭiet, growth, body temperature, muscle mass, and heredity can influence a woman's BMR. An Illustrated Guide to Pediatric Surgery. Current breastfeeding research does not indicate that breast milk intake changes with baby’s age or weight between one and six months. Infant Nutrition and Feeding: A Guide for Use in the WIC and CSF Program.
Breast milk nutrient content and infancy growth. Breastfeeding Reduces Postpartum Weight Retention. Core Curriculum for Lactation Consultant 3rd Edition.
When a baby starts being given the complementary feeding, the main calorie source is breast milk, and then it is reduced gradually. 9Įstimated calorie requirements (based on age) are shown below: 4 Calorie requirements of 0-1 year old infant is about 100–120 ccal/kg/day. The common indicator showing if an infant gets enough calories per day is weight gain, length, and head circumference. Technically, a kilocalorie is the amount of energy required to increase the temperature of 1 kilogram water as much as 1 0C 8. Kilocalorie is a measurement used for energy produced by food. Somebody’s energy needs are pictured by the amount of ‘calorie’ needed by a unit of the body weight.

In the first month, the caloric content in the preterm milk and full term milk is shown below 7: Starvation and dehydration will decrease the breastmilk volume. In other words, the caloric content in breastmilk is not dependent on the mother’s diet, unless she is malnourished. The mother’s diet has no effect on the amount of fats and lactose in the breast milk, but has an effect on the type of fats in breastmilk 4. The calories in a normal supply mother who only breastfeeds are higher than those of a mixed-feeding mother 6. 5Ī breastfeeding mother with overproduction tends to have the breast milk containing less fats, protein and higher lactose. Breastfeeding mothers tend to lose the pregnancy weight easier. 3 Otherwise, fats and lactose in breast milk production have an effect on the mother’s weight. Fats in breast milk also depend on a mother’s body mass index, pregnancy weight gain, parity, menstruation, and breastfeeding frequency. Compared to the preterm milk, full term breast milk contains less fat and water. It depends on babies’ requirements and growth. The composition of breast milk is dynamic. Average caloric content in breast milk is 67 ccal /dL 4.Ĭalories in breastmilk (average) : 67 ccal/dL The breast milk calories from fats, lactose, and a little from protein, are about 65-70 ccal/dL 3. 2 The fat in breast milk remains stable, about 3,4-4,5%, starting from 21 days after delivery. Breast milk contains about 7g/dL lactose. Lactose is the main form of ‘sugar’ in breast milk. Fat and lactose are the main sources of calories in breast milk, about 50-65% and 35-40%. Breast milk contains 87% water, 3.8% fat, 1.0% protein, and 7% lactose 1.
