Process for controlling body weight
View Patent ↗The disclosure relates to a process for controlling body weight in which selection of food servings is based on a calculated point value and a range of allotted daily points which is adjusted for weight change. The calculated point value is a function of measured calories, total fat and dietary fiber for serving sizes specified in readily estimatable units. A range or maximum number of points allotted per day may be calculated based on current body weight, caloric reduction to be achieved, physical activity level, and physical activity duration.
1. System for calculating Points values for use by a person in a weight control process to produce a restricted food intake for the current weight of the person taking into account food ingested and activity level comprising:
means for determining whole number Points values, p, for food servings ingested by the person characterized by the equation
p

where c is calories, f is fat in grams and r is dietary fiber in grams for each candidate food serving and where k 1 is about 50, k 2 is about 12 and k 3 is about 5; and
means for determining whole number activity Points, P A , on the basis of intensity level and duration of physical exercise for addition to a number of basic Points appropriate for the current weight of the person and weight change to be achieved.
2. The system of claim 1 wherein the activity Points, P A , are whole numbers characterized by the equation

wherein k 4 is a predetermined numerical weighting factor determined on the basis of intensity level of physical exercise.
3. The system of claim 2 , wherein k 4 is between 0.05 and 0.2.
4. The system of claim 2 , wherein k 4 has at least three progressively increasing values corresponding to low, moderate and high intensity physical exercise.
5. The system of claim 2 wherein k 4 is equal to about 0.05 for low intensity physical exercise, about 0.07 for moderate intensity physical exercise and about 0.18 for high intensity physical exercise.
6. The system of claim 2 , wherein the addition of activity Points to daily basic Points occurs when determined activity Points exceed a predetermined threshold of 1 to 3 activity Points per day.
7. An apparatus for calculating Points values for use by a person in a weight control process comprising
an electronic computing device having a memory which determines a total Points value (sum of p values) for food servings ingested during the day in which the Points value p for each food serving ingested is characterized by the equation

wherein c is the number of kilocalories in the food serving;
f is the total amount of fat in the food serving;
r is the amount of dietary fiber in the food serving;
k 1 , k 2 and k 3 are preselected constants;
k 2 is in the range k 1 /4.5 to k 1 /1.5 when f is measured in grams;
k 3 is in the range of k 1 /20 to k 1 /5, when r is measured in grams; and which determines activity Points, P A , characterized by the equation

where k 4 is determined on the basis of the intensity level of the physical exercise; which upwardly modifies basic Points allotted per day for the person by a number of Points corresponding to the determined activity Points, P A , over a predetermined threshold; and which determines the number of Points left for the day after subtracting the sum of p values for the food servings ingested; and
means for displaying the number of Points left for the day.
8. The apparatus of claim 7 , wherein k 4 is between 0.05 and 0.2.
9. The apparatus of claim 7 , wherein k 4 is equal to about 0.05 for low intensity physical exercise, about 0.07 for moderate intensity physical exercise, and about 0.18 for high intensity physical exercise.
10. The apparatus of claim 7 , wherein the predetermined threshold is 1 to 3 activity Points per day.
11. The apparatus of claim 7 , wherein the memory of the computing device stores the parameters necessary to make the Points determinations.

wherein c is the number of kilocalories in the food serving;

k 1 , k 2 and k 3 are preselected constants;
k 2 is in the range k 1 /4.5 to k 1 /1.5 when f is measured in grams; and
k 3 is in the range of k 1 /20 to k 1 /5, when r is measured in grams;
a process for determining a number of Points remaining as an indication of the food which may be ingested by the person; comprising:
determining the basic Points allotted based on the person's current body weight;
determining activity Points based on the weight of the person and on the intensity level and duration of physical exercise of the person; and
adding the basic Points and activity Points and subtracting the total Points (sum of the p values) for food servings ingested by the person to determine the number of Points remaining.
