e've added a separate category, apart from the category of weight loss unintentional, for dysphagia requiring the absorption of liquids thickened. We assume that people will have a normal weight.People with weight loss and dysphagia will be classified in this category of weight loss unintentional.
All the conditions contained in this category requires an additional energy for the treatment of weight loss. The cost is based on the percentage of weight loss.
In clinical practice, prescription or energy needs in this area based on sex, age, height, weight, activity level and the stress factor. For purposes of this exercise, all calculations are based on data by referring to a man 70 kg.
Among the non-obese, weight maintenance requires a contribution of 25 to 35 kcal / kg body weight. (22)
We have therefore calculated that the range of daily energy needs for an adult male who weighs 70 kg is 1750 to 2450 kcal / day.
70 kg x 25 kcal = 1750 kcal
70 kg x 35 kcal = 2450 kcal
People who undergo weight loss due to a medical condition will be in a state of metabolic stress, so we used the need for higher energy 2450 kcal / day to calculate the costs.
In the absence of specific anthropometric data, we estimate 640 to 820 kcal / day the daily cost of energy to gain weight in the context of various medical conditions. (23) We used this figure to calculate the total energy requirements for each category of weight loss.
