Expert: ‘Extreme Diets Don’t Work’
Weight loss researcher Frank M. Sacks, MD, of Harvard School of Health says the more extreme the diet, the less likely someone is to stick to it.
“Extremely low-carbohydrate diets may be safe, but people tend to get sick of them after a few months,” he says. “In this study, 42% of the low-carbohydrate dieters dropped out over time. They also reported more symptoms associated with the diet.”
Those symptoms included constipation, bad breath, and dry mouth.
He agrees that dieters should choose a weight loss plan they can stick to, with the goal being safe, gradual weight loss.
By following his own advice, Sacks was able to lose 15 pounds over nine months and keep it off.
“Half a pound a week may not sound like much, but over the course of a year that’s 24 pounds, which is huge,” he says.
