Of course, Jakicic's findings also support that other factor crucial for successful weight loss -- cutting calories.
The 200 women he evaluated, typically 5-foot-4 and weighing 192 pounds when his study began, all cut their calories to 1,200 to 1,500 a day and fat intake to no more than 30% of total calories consumed.
"In this study, they cut calories by almost one-third their previous levels," says I-Min Lee, MBBS, ScD, of Harvard Medical School, who wrote an accompanying editorial to Jakicic's study.
"It's a balance issue. You can exercise very little but eat nothing and still lose weight. It comes down to how much you are willing to sacrifice, in terms of what you eat and what you do to burn it off. Most people don't want to cut their food intake by too much."
Still, Lee tells WebMD that this study shows that a little exercise, done consistently, can do a lot of good.
Pump Up Your Fitness, Too
-------------------------------------
The researchers also found that all four levels of exercise had
same effect on improving fitness level. Looking at increases in oxygen consumption -- a measure of how well
body uses oxygen for energy --
researchers found that all four groups had similar improvements after 12 months of exercise.
The Greatest Weight Loss
-------------------------------------
"You will get
greatest weight loss from changing your caloric intake in
short run," says Jakicic. "However, it appears that without
exercise,
initial weight loss is less and
long-term maintenance of weight loss becomes extremely difficult. So, diet without exercise will make
maintenance of weight loss very difficult."
Conversely, he says that exercise without dieting makes weight loss slow and probably less effective -- especially if you're looking to drop serious poundage.
His recommendation for
ideal combination: "If an individual reduces their current level of intake by 500 to 1,000 calories per day and exercises 30 to 60 minutes a day,
weight loss will be around two pounds per week, on average."
