What's the hottest trend in the diet world? The concept of dieting only part-time. And after conducting numerous studies to understand how it works, nutrition professor Krista Varady has crafted a unique approach to intermittent fasting that helps dieters lose up to 30 pounds in eight weeks, reported CBS 10 News on April 4.
Based on Varady's research, dieters benefit more from intermittent fasting than regular diets because the focus is on fat loss. Other diets may result in muscle loss.
"In our studies, we show people tend to lose 90 percent weight as fat," Varady told CBS News.
In addition to weight loss, intermittent fasting resulted in lower levels of LDL "bad" cholesterol levels and blood pressure, she added. Varady has authored a book about her research and the details of her intermittent fasting weight loss plan: "The Every-Other-Day Diet: The Diet That Lets You Eat All You Want (Half the Time) and Keep the Weight Off" (click for details).
What's involved? In a nutshell (which you can eat on those alternate "feast" days), dieters follow these guidelines:
- On "fast" days, women are limited to 400 to 500 calories, while men are allotted 500 to 600 calories.
- On "feast" days, you can nosh on anything and everything you desire.
Varady also has discovered that dieters tend to only eat 10 percent more on their "feast" days, despite those who doubt the premise.
"When you forbid foods, people tend to over-consume," Joy Dubost, a food scientist and registered dietitian who is a spokesperson for the Academy of Nutrition and Dietetics, argued against the fasting concept. "That could be the fear with this type of diet, that you abstain, and then the next day it's a free pass and you can eat what you want."
In an alternative to Varady's approach, some weight loss experts feel that the semi-fast days are required only two days a week. Read about the "5:2 diet," also called the "Fast Diet," by clicking here.
