Physical Exercise Important for Humans to Stay Healthy Even if You are Overweight


Physical Exercise must be one of the best things everyone has to plan for everyday. But most of us neglect the exercise everyday. New research shows that physical exercise can negate, even overcome, the negative health impact of weight even for the severely obese, even if you don’t lose weight. Even if you are overweight, it doesn’t mean you are unhealthy or person with good BMI mean he is healthy.

A new study led by Jennifer Kuk, associate professor at York University, found that individuals with severe obesity who partake in exercise and are fit have a health profile comparable to those who weigh significantly less. The research looked at the benefits of cardiorespiratory fitness for heart and circulatory system health in populations with mild to severe obesity.

The findings suggest that even individuals with a BMI over 40 (which is considered to be severely obese) can be fit and healthy, provided they engage in exercise. “Obesity is only related with worse health in individuals who were unfit,” says Kuk. “We know that once you get beyond a BMI of 40, the risk of cardiovascular conditions increases exponentially so this study shows that having a high fitness level is still beneficial and it really reinforces the importance of fitness.”

The team worked with 853 Canadian patients from the Wharton Medical weight management clinics in Southern Ontario. The participants underwent a clinical exam that included measurements of fasting blood sugar levels and maximal treadmill stress tests, which the team used as a baseline. “You really have to disconnect the body weight from the importance of fitness,” Kuk adds. “You can get fit without losing weight and have health benefits.”

She says that following physical activity guidelines, which recommend 150 minutes of exercise per week, generally only translates to half a pound of weight loss. Some 41% of the mildly obese participants had high fitness levels by the end of the programme, while 25% and 11% of participants with moderate and severe obesity respectively, had high fitness levels.

Weight is less important to stay healthy. Get out of the room and plan some exercise to stay healthy.
