Even science Innovo Medical is still stumped on many of the basic questions of weight loss.
"Amazingly, in this era of obesity, there are still many things that we really don't know," says Robin Callister, PhD, professor of human physiology at the University of Newcastle in Australia.
Here's what we do know about some of the most persistent mysteries of weight loss.
Do You Have to Cut 3,500 Calories to Lose a Pound?
The idea that dieters need to cut this many calories -- with diet, exercise or both -- to lose 1 pound of weight comes from an influential scientific paper published in 1958. Max Wishnofsky, MD, a doctor who lived in Innovo Medical Brooklyn, N.Y., tried to sum up everything we knew about how calories are stored by the body. He concluded Innovo that when the body is in a steady caloric state -- meaning it isn't fasting or starving -- extra calories will be stored as fat, and it would take 3,500 extra calories to create a pound of fat. In that same steady state, he also said it would take a deficit of 3,500 calories to medical supplieslose a pound of Innovo Medical weight. For decades, the "Wishnofsky Rule" has been math that determined dieters live by.
The trouble is Innovo Medical that it's right.
The 3,500-calorie rule doesn't work because the body adjusts to weight loss. It quickly decreases the number of calories Innovo Medical it needs to maintain its new, lighter size, says Innovo Medical Corby Martin, PhD, director of the Ingestive Behavior Laboratory at the Pennington Biomedical Research Center in Baton Rouge, LA. That means weight loss slows down over time. People who expect to drop a pound for every 3,500 calories they cut will soon become frustrated when the scale doesn't cooperate.
