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. Other factors that can be considered in the calculation include the thermic effect of food, though this is not always factored into the calculation, and has a relatively smaller impact than BMR and activity level.If you failed to gain sufficient tissue stores during pregnancy, then all lactation needs must be met through diet alone. Once BMR is calculated, it is typically multiplied by an activity level factor, which is based on factors such as exercise and whether a person has a sedentary or very active job. They are generally pretty similar, but the Katch-McArdle Formula, for example, which takes metabolic activity (resulting from differences between lean body mass and body fat) into account, can be more accurate for lean persons. Some of the more commonly used equations for estimating BMR include the Mifflin St-Jeor Equation, Harris-Benedict equation, and Katch-McArdle Formula. This includes physical characteristics such as age, gender, height, and weight. The calculation usually begins with an estimation of basal metabolic rate (BMR), which is based on the use of equations that have been developed for this specific purpose. TDEE is calculated based on the factors described above. Protein, for example, has a far larger thermic effect than dietary fat, since it is more difficult to process. It is sometimes estimated as 10% of food energy intake, but this can vary significantly depending on the type of food consumed. The thermic effect of food, also referred to as specific dynamic action, is the amount of energy required by the body to process and use food. These factors are more specifically referred to as the thermic effect of activity, and non-exercise activity thermogenesis (energy expended for non-sleeping, eating, or sports-like exercise). This includes deliberate exercise as well as other activities that a person may undergo as part of their job or typical daily activities. In other words, it is the minimum energy needed to maintain a person's vital organs only.Īctivity level is a factor that is based on the amount of activity a person undergoes. More often, it is estimated using factors such as a person's basal metabolic rate (BMR), activity level, and the thermic effect of food.īMR is a person's energy usage rate while at rest in a temperate environment when the digestive system is inactive. TDEE is hard to measure accurately and varies day by day. It is the total energy that a person uses in a day. TDEE stands for total daily energy expenditure.
