Rat Science fools Weight Loss Researchers

Hamilton, April 15, 2009: ‘Rat Science’ Doesn't Work For Humans.

Obesity experts have failed to discover the secret to successful weight loss because their work with rats in the laboratory does not relate to real human experience. That's the opinion of one of Canada's leading lifestyle experts.

"In the past 11 years we have consulted with thousands of Canadians who are consistently consuming less than 1200 calories per day, often for months and years at a time without any weight loss," explains Keep America / Keep Canada Slim President Lee Fairbanks. “This flies in the face of traditional science which has always claimed that weight loss or weight gain is a simple equation of calories in versus calories out.”

Maintenance calorie levels for non-exercising women typically range between 1600 and 2000 calories a day.

"When I have discussed this phenomenon with researchers and scientists they simply tell me that all of these thousands of people have been lying constantly about what they actually eat. This is a personal insult to all involved and is also clearly invalid as an explanation of what we observe in the real world."

Keep Canada Slim is a weight control program that teaches a new approach to shopping, cooking and eating. It was founded 11 years ago by Fairbanks and is the only program in Canada which establishes minimum calorie levels for each individual client as well as maximum calorie levels.

Fairbanks claims that a significant number of Canadians - "in the millions" - are currently undereating almost every day in a desperate attempt to either lose weight or maintain their current weight. This habit of undereating leaves them nutritionally deficient and increases their risk of degenerative disease later in life.

Perhaps more important to those trying to lose weight, Fairbanks says his research with real Canadians shows that this low-calorie lifestyle does not create ongoing weight loss and in fact has the risk of causing muscle loss in the absence of sufficient calories for energy from food.

Fairbanks says the fault lies in the way scientists use rats to study obesity.

"The human body has an amazing ability to adapt to whatever challenges it faces,” explains Fairbanks. “During repeated cycles of low-calorie diets leading eventually to a permanent low-calorie lifestyle, the body adapts its metabolic processes to allow it to survive for years without measureable health risk despite not receiving adequate levels of energy and nutrition.”

“In a lab rats are put through a single cycle of dietary adjustments and then killed so that the results can be measured. Because of this single cycle approach it's natural for scientists to conclude that weight control is simply a matter of calories in versus calories out. This equation does work in humans the first or second time they try it. However scientists never experience the cyclical nature of ongoing dieting and therefore do not observe the adaptation process.”

Fairbanks says that this knowledge is slowly creeping into academic circles (see reference below) but that it may be decades before scientists can agree on how this process occurs and be willing to put their reputations at risk by making these claims publicly.

"With advanced real-time measurement of human metabolism and continued studies of existing diet programs some scientists are starting to realize that the traditional explanations don't explain what is happening. There are clinical trials emerging which prove that people do not lose the expected weight based on the calories in - calories out equation. However no one has made this claim publicly.”

“In the meantime the millions of Canadians who are already undereating are still being told to eat less and exercise more. In our program it is routine for us to insist that clients eat more calories every day than they are currently eating. As soon as they surpass their minimum calorie level the adaptive process stops and weight loss restarts. This has been the case with thousands of real people living real lives. Lab rats are not people."

Fairbanks points out that Canadians have been following the “eat less” instructions for decades, and yet even highly-educated, highly-motivated people are not having success losing weight this way.

“Demographic researchers like to point out that obesity rates are higher among low-income and poorly-educated Canadians, but go to any $100-a-plate fund-raising dinner and you will see that obesity rates are too high in every level of our society. It’s time we stopped studying rats and starting learning what real people are doing every day. Then our message will have validity.”
