Researchers Explore the Diet-Exercise Connection

Finding the most effective weight loss regimen is a constant struggle for those who are seeking to lose weight. It seems that everywhere dieters turn, they are presented with conflicting information about which approach will yield the fastest, easiest, and most lasting weight loss results.

One issue that is a focus of much debate is the role of exercise in an effective weight loss plan. Most experts contend that you have to break a sweat on a regular basis to achieve lasting weight loss, but a growing group of naysayers contend that it?s what (and how much) you eat that will ultimately determine the success of your efforts to slim down.

Researchers have also begun to focus more attention on the issue of exercise as part of a weight loss regimen. This week, we?ll review what some of the latest studies addressing this always-contentious issue have had to say on the matter.

Exercise Not Required For Weight Loss

Researchers at the Pennington Biomedical Research Center in Baton Rouge, Louisiana challenged the longstanding assumption that physical exercise is mandatory for overweight men and women who want to shed excess pounds. According to the results of their analysis, it doesn?t matter whether a calorie deficit is created through dietary restriction, increased physical activity, or a combination of both. All three methods are equally effective as part of a weight loss effort.

In their study, the participants who adhered to restricted calorie diets and those who dieted and exercised lost approximately the same amount of body fat. The participants in the exercise-only group lost, on average, much less weight.

Although the researchers affirm the importance of physical exertion for improving overall health, they point out that exercise is not absolutely necessary in order to lose weight. Instead, the only non-negotiable aspect of an effective weight loss regimen is ensuring that you are taking in fewer calories than you are burning on a daily basis.

Even Minimal Exercise Helps Overweight Women Reduce Disease Risk, Improve Health

Obesity is associated with a laundry list of negative health outcomes, including heart disease, diabetes, stroke, cancer, and many other disorders and diseases. However, some people are intimidated by the prospect of initiating an exercise regimen. This is often the case for women who are significantly overweight. For women in this group, lifestyle constraints and physical limitations can make the prospect of thirty minutes on a treadmill overwhelming.

The results of one recent study suggest that even short bursts of exercise may have a sizable impact on the health outlook and overall quality of life for significantly overweight women. According to researchers at the University of South Carolina, as little as ten minutes a day of moderate physical exertion has been proven to have a positive impact.

Among the 427 overweight women who participated in the study, as little as 75 minutes per week of moderate physical exertion was linked with positive health benefits such as increased oxygen capacity, a smaller waist, and reduced blood pressure, although little or no sustained weight loss was reported.

This works out to approximately 10-15 minutes a day of exercise, a commitment that most people feel comfortable making. Furthermore, the researchers underscore the fact that the exertion need not be ?exercise? in the traditional sense -- it?s entirely possible to get one?s daily quota in vigorous housework, playing games with children, or gardening.

Strength Training Less Effective for Obese People

According to the results of a recent study conducted by researchers at the University of Connecticut, men and women who are overweight or obese get fewer benefits from a program of strength, resistance, and/or weight training than do their non-obese counterparts. In a study that assessed the benefits of strength training for adults aged 18-40, the researchers found that obese and overweight participants gained an average of four to seventeen percent less muscle mass than thin participants.

The researchers hypothesized that some of the same genetic differences that make some people more likely to become overweight could also account for the differences in muscles? response to weight training. However, the researchers contend that this type of exercise is still beneficial for overweight individuals, although the results of such a program won?t be as immediately evident.

Although these study results are varied, most experts continue to recommend daily physical exercise as an important part of a healthy lifestyle. Check back each week for more research news geared to help you fine-tune your weight loss regimen!
