Abstract

Provided are methods for reducing food consumption, and methods for altering behavioral, neurological, psychological, or physiological responses to a food portion, mainly for use by an obese or overweight user, or by a user at risk of weight gain. Also provided are user-interactive systems and apparatuses for employing such methods.

Claims

1. A method for reducing food consumption by an overweight or obese user when employing a user-interactive system while eating, relative to food consumption when the user-interactive system is not employed, and without having to determine food portion size, the method comprising:

(a) providing a user-interactive system that comprises (i) a camera means for generating an image of a bite of food that is to be consumed by the user, (ii) an image-processing means for receiving from said camera means the image of the bite of food that is to be consumed by the user and magnifying the image to obtain a magnified image of the bite of food, (iii) a display means for receiving from the image-processing means and displaying the magnified image of the bite of food to obtain a displayed magnified image of the bite of food, (iv) a food source, and (v) a reference object;

(b) allowing the user to present to the camera means a bite of food that is to be ingested, under conditions that permit the user-interactive system to generate and magnify an image of the bite of food and display a magnified image of the bite of food on the display means, said bite of food comprising all or a portion of the food source;

(c) allowing the user to visually compare the reference object to the displayed magnified image of the bite of for a time period immediately before ingestion of the bite of food;

(d) allowing the user to ingest the bite of food; and

(e) permitting the user to repeat steps (b)-(d) zero, one, or a plurality of times up to a satiety point, and thereby reducing a first level of food consumption by the user when employing the user-interactive system while eating, relative to a second level of food consumption by the user when the user-interactive system is not employed.

3. The method of either claim 1 or claim 2 wherein the reference object is a hand of the user.

4. The method of either claim 1 or claim 2 wherein the reference object is selected from the group consisting of an artificial hand, a scale model of an artificial hand, an image of a hand and an image of a scale model of a hand.

5. The method of claim 4 wherein the artificial hand is an artificial human hand and the image of a hand is an image of a human hand.

6. The method of either claim 1 or claim 2 wherein the reference object is an article of manufacture having dimensions that conform to a manufacturing industry standard.

7. The method of claim 6 wherein the article of manufacture is selected from the group consisting of:

(a) an electronic or electrical device or a component thereof that is selected from the group consisting of;

a removable battery for a portable electronic device, an alternating current (AC) wall plug, an AC wall outlet, a light bulb, a compact disc, a telephone handset, a computer mouse,

(b) a unit of currency that is selected from a paper bill of standard denomination and a metal coin of standard denomination,

(c) a common household item that is selected from a twelve-ounce beverage can, a twelve-ounce beverage bottle, a playing card, a deck of playing cards, a pair of eyeglasses, a pair of sunglasses, a ruler,

(d) a scale model of any article of manufacture according to (a)-(c).

8. The method of either claim 1 or claim 2 wherein the user is selected from an overweight user, an obese user, a user having one or more genetic, familial or environmental risk factors for an obesity-linked cancer, a user having one or more genetic, familial or environmental risk factors for stroke, a user having a history of yo-yo dieting or weight cycling, and a user having a condition that is selected from Type 1 diabetes, Type 2 diabetes, impaired glucose tolerance, insulin resistance, sleep apnea, osteoarthritis, gout, high blood pressure, and abnormal blood lipid levels.

9. The method of either claim 1 or claim 2 wherein the user has (i) a leptin signaling deficiency, (ii) decreased left dorsolateral prefrontal cortex (LDLPFC) activity in response to a meal, or (iii) an unhealthy hedonic response to a food portion.

10. The method of claim 9 wherein the leptin signaling deficiency is modulated by at least one of (i) extending duration of the time period during which the reference object is visually compared to the displayed magnified image, and (ii) increasing a degree of magnification of the magnified image.

11. The method of either claim 1 or claim 2 wherein the camera means is selected from the group consisting of a closed-circuit television camera, a digital camera, a digital video camera, a web camera and a projection camera.

12. The method of either claim 1 or claim 2 wherein the camera means is attached to the display means by a support member.

13. The method of claim 11 wherein the image-processing means is attached to at least one of the camera means and the display means.

14. The method of either claim 1 or claim 2 wherein the image is selected from the group consisting of an optically projected image, a television image and a digital image.

15. The method of either claim 1 or claim 2 wherein the user-interactive system comprises a computer operatively coupled to the camera means, the image-processing means and the display means, said computer being programmed to control one or more of image generation, image magnification and image display.

16. The method of either claim 1 or claim 2 wherein the display means is selected from a computer screen, a flat-screen television, a cathode ray tube (CRT) display and a light-projection screen.

17. The method of either claim 1 or claim 2 wherein the user-interactive system comprises a lighting means for illuminating the bite of food when it is presented to the camera means.

18. The method of either claim 1 or claim 2 wherein in step (b) the user presents the bite of food to the camera using a first hand of the user, and wherein in step (c) the reference object that is visually compared is a second hand of the user, said second hand being contralateral to said first hand.

19. The method of either claim 1 or claim 2 wherein the image-processing means comprises a computer processor and a computer-readable medium having executable instructions stored thereon for converting an image signal generated by the camera means into a display signal that can be displayed by the display means.

20. The method of either claim 1 or claim 2 wherein the user-interactive system includes a protective covering such as a tray that protects one or more of the camera means, the image-processing means and the display means from food spillage.

21. The method of either claim 1 or claim 2 wherein the display means comprises a head-mounted visual display apparatus, and wherein in step (c) the user is allowed (i) to visually compare the reference object to one or a plurality of displayed magnified, minified, or both magnified and minified images of the bite of food, said plurality comprising images having different magnification factors, or (ii) to visually compare one or a plurality of magnified, minified or both magnified and minified images of the reference object to one or a plurality of displayed magnified, minified, or both magnified and minified images of the bite of food, said plurality of images of the bite of food and said plurality of images of the reference object each comprising images having different magnification factors.

2. A method for altering behavioral, neurological, psychological, or physiological response to a food portion by a user including an obese or overweight user or a user at risk of weight gain, when employing a user-interactive system while eating, relative to behavioral, neurological, psychological, or physiological response to a food portion when the user-interactive system is not employed, and without having to determine food portion size, the method comprising:

(a) providing a user-interactive system that comprises (i) a camera means for generating an image of a bite of food that is to be consumed by the user, (ii) an image-processing means for receiving from said camera means the image of the bite of food that is to be consumed by the user and magnifying the image to obtain a magnified image of the bite of food, (iii) a display means for receiving from the image-processing means and displaying the magnified image of the bite of food to obtain a displayed magnified image of the bite of food, (iv) a food source, and (v) a reference object;

(b) allowing the user to present to the camera means a bite of food that is to be ingested, under conditions that permit the user-interactive system to generate and magnify an image of the bite of food and display a magnified image of the bite of food on the display means, said bite of food comprising all or a portion of the food source;

(c) allowing the user to visually compare the reference object to the displayed magnified image of the bite of food for a time period immediately before ingestion of the bite of food;

(d) allowing the user to ingest the bite of food; and

(e) permitting the user to repeat steps (b)-(d) zero, one, or a plurality of times up to a satiety point,

and thereby altering a first level of behavioral, neurological, psychological, or physiological response to a food portion by the user when employing the user-interactive system while eating, relative to a second level of behavioral, neurological, psychological, or physiological response to the food portion by the user when the user-interactive system is not employed.
