Step 1
The first step is to ascertain the present calorie intake proportion. (Typically, people tend to have a greater percentage of fat in their diets than the ,typical proportion.)
Assuming that a person was originally consuming 2,500 calories at the start of the programme, then the
Expected Ideal Proportion of calorie intake is:
Carbohydrates 60% of 2,500 = 1,500 calories
Fats 20% of 2,500 = 500 calories
Proteins 20% of 2,500 = 500 calories
Step 2
Calorie Reduction: A maximum of 5 per cent per week, which means that in this particular case the calorie intake will be reduced by 5 per cent of 2,500 = 125 calories per week.
Total calorie reduction at the end of 6 weeks = 6 x 125 = 750 calories.
So the total calorie intake of that person after six weeks will be = 2,500(original intake) - 750 (reduction) = 1,750 calories.
Step 3
Adjusted Nutrient Percentage
Carbohydrates 60% of 1,750 Fats =1,050 calories
20% of 1,750 = 350 calories
Proteins 20% of 1,750 = 350 calories
The gradual decrease of calorie intake is achieved by reducing the intake of calories and replacing traditional meals with crafted meals having a higher degree of fibres (which typically don't have calories and are roughage), liquids and foods that increase the metabolic rates.
