![]() Most studies have shown similar BMR in the lactating and non-lactating state. For men: BMR 66.5 + (13.75 x weight in kg) + (5.003 x height in cm) - (6.755 x age in years) For women: BMR 655.1 + (9.563 x weight in kg) + (1.850 x height in cm) - (4. Research into changes of Basal Metabolic Rate during breastfeeding has proved contradictory and ambiguous. ![]() Weight LossĪ review of over 17 studies found that mean rates of weight change in the first 6 months postpartum are greater in well-nourished women (-0.8 kg or -1.76 lbs per month) than in undernourished women (-0.1 kg or -0.2 lbs per month). ![]() This amount takes into account the energy released from tissue stores. The most recent and thorough set of research concludes that įor exclusive breastfeeding through 5 months postpartum, the energy cost of lactation (based on mean milk production) is 454 Calories per day (over non-pregnant, non-lactating women). However, caffeine can be found in breast milk, so consumption of coffee and energy drinks should be managed carefully. Although assumed, caffeine does not generally lead to a diuretic affect (reseach is inconsistent). It is generally not necessary to consume extra fluids, following your body’s natural cues is sufficient to meet lactation needs ( source). Where energy input from diet is not enough, tissue stores will be mobilized. This increase in energy output is from milk production – BMR (Basal Metabolic Rate) remains largely the same whether breastfeeding or not. Research of healthy breastfeeding women has shown that – while lactating – women have a greater energy output (~2718 Calories) than when lactation has ceased (~2528 Calories). If gradual weight loss is required – then this should be 500 Calories per day. How Many Calories Should a Breastfeeding Mother Consume? Earlier ResearchĪdditional energy needs for an exclusively breastfeeding woman is approximately 670 Calories per day. Therefore, gradual weight loss should occur. The calculator determines daily calorie needs for maintenance, adds the energy cost of lactation, then substracts a factor of 15%. The remaining energy will be met with diet. Provided that a well-nourished woman has gained this amount of weight – then fat stores accumulated during pregnancy may be used to cover part of the energy cost of breastfeeding. Some of this is for the development of the baby, and some is for maternal energy stores to be used throughout lactation. Mean weight gain during the 9 months of pregnancy is 26 pounds (12 kilograms). Please consult your physician or nutritionist for a more accurate approach that takes into account your own particular situation. In this situation you should be consuming more food. If you failed to gain sufficient tissue stores during pregnancy, then all lactation needs must be met through diet alone.
