Amazing results from medical testing of metabolic rates of overweight subjects. Watch the other videos on this channel for additional clinical testing using this same very sophisticated, and accurate, medical technology.

The mistake this woman made is the "rule" and not the exception to the rule. The DLW (doubly-labeled water) test used to "spy" on how much this woman actually ate during the test has been widely used since the late 1980's. The DLW test is truly an amazing scientific breakthrough in terms of testing human metabolic rates and processes. For more information about DLW go to Wikipedia and input "doubly labeled water" or click on this link: http://en.wikipedia.org/wiki/Doubly_labeled_water

More than 100 DLW studies, published in the world's leading medical journals such as The New England Journal of Medicine, JAMA (Journal of the American Medical Association), International Journal of Obesity Research, etc., have consistently found exactly the same thing the researchers in this documentary found. Literally thousands of thin and overweight people have been tested using this ingenious method. Not only does the DLW testing enable researchers to accurately determine a person's metabolic rate, it allows them to calculate how many calories they actually consumed during the test (usually a 7- to 14-day period). Invariably, virtually ALL of the 100s of published DLW and related studies over the past 20+ years conclusively prove three things:

1) Overweight people don't have slow/defective metabolisms -- they in FACT have much faster metabolisms (see the other videos on this channel),

2) They burn far fewer calories in physical activity than they think do, and

3) They don't know how much they are actually eating (in terms of total caloric intake) and UNDERREPORT all the food and/or quantities they consume when tracking it via food diaries, questionnaires, or from recall.

The narrator notes eslewhere in the documentary that studies show the average person typically underreport their intake about 50%. That means that if they really ate 3,000 calories per day like this woman did, they would record/report they ate only about 1,500 calories per day (and believe it like this woman did). A 100-calorie per day mistake every day for a year equals a 10-lb weight gain.

The DLW testing, and other methods of metabolic testing and research over the past several decades has shed light on several myths about why people are overweight and "believe" they can't lose it.
