You can be Fat and Still be ‘Fit’

Highlights

Individuals with severe obesity or a BMI greater than 40 can be physically fit and healthy
Individuals with severe obesity are more likely to develop high blood pressure, glucose, and triglycerides if their fitness level is lower than 20 percent
The above-mentioned risk factors can be avoided if individuals have an 80 percent of fitness level

Individuals with severe obesity or those with a BMI greater than 40 can be physically fit and healthy, reveals a new study.//

Can an overweight individual be fit and healthy? That's the question the research team at York University's Faculty of Health tried answering in their new study, which reveals that physical activity can be equally important, perhaps even more than just weight for people living with severe obesity.

Obesity Prolongs Life For Men With Metastatic Melanoma
Men with metastatic melanoma have a better survival rate if they are obese as they respond better to immunotherapy.

‘Obese individuals do not necessarily need to lose weight to be healthy. Being physically active can help them be fit and healthy.’

The study was led by Jennifer Kuk, associate professor in York University's School of Kinesiology and Health Science, and collaborator Dr. Sean Wharton, MD, medical director of the Wharton Medical Clinic and adjunct professor at York University.

Fat but Fit

Individuals with severe obesity who are fit have a similar health profile to those who weigh significantly less than them.

Obesity can Lead to Sudden Cardiac Arrest in Young People
Screening for obesity and other common cardiovascular risk factors is important to prevent sudden cardiac arrest at a younger age.

This study aimed to analyze the benefits of cardiorespiratory fitness on cardiovascular health in the population with mild to severe obesity.

The results revealed that individuals with even severe obesity or those with a BMI greater than 40 could be physically fit and healthy.

Spiked Canadian Obesity Rate may Lead to Higher Cancer Burden
Reducing the number of overweight and obese Canadians could potentially prevent a lot of cancer cases by 2042.

"Obesity is only related to worse health in individuals who were unfit. 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 reinforces the importance of fitness," said Kuk.

Kuk said that exercising for about 150 minutes every week, according to physical activity guidelines can reduce less than half a pound of weight loss. However, this amount of exercise can bring about drastic improvements in health for those individuals with severe obesity.

Eating Nuts Regularly can Stave Off Obesity Risk
People who regularly eat nuts or consume healthy snack were found to have a five percent lower risk of carrying extra pounds, compared to those who did not.

"You have to disconnect the body weight from the importance of fitness. You can get fit without losing weight and have health benefits," said Kuk.

The data was collected from 853 Canadian patients who were attending Wharton Medical weight management clinics, Southern Ontario.

These patients completed a clinical exam including fasting blood glucose levels and a maximal treadmill stress test.

The amount of fitness required to achieve health benefits was far less than what is usually thought by most individuals.

Benefits of Exercise can outweigh Health Effects of severe Obesity

The results revealed that most significant health benefits come from avoiding the lowest 20 percent of fitness levels, which means that 80 percent of people can be fit enough to get health benefits.

In this study, 41 percent of participants with mild obesity were found to have high fitness levels. On the other hand, 25 percent and 11 percent of the participants with moderate and severe obesity were also found to have high fitness.

Individuals with severe obesity are more likely at the risk of developing high blood pressure, glucose, and triglycerides if their fitness level is in the lowest 20 percent. However, these risk factors were found to be uncommon if they had an 80 percent of fitness level.

In previous studies, less physical activity is required to improve health when compared to losing weight. However, this is the first research study that suggests that physical activity is more important for individuals with severe obesity.

Wharton says, "In my practice, I see many patients who are looking for different results. There are some patients that want to significantly improve their health and others that are only looking for an aesthetic goal. When it comes to health, this study reinforces the notion that people don't need to lose weight to be healthy."

Benefits of Exercise

Exercise is any physical activity, which enhances the overall fitness of the body. A good balance between a healthy diet and exercise for maintaining fitness and a life free of diseases need to be maintained.

Regular exercise helps increase muscle strength. A healthy body houses a sound mind, which in turn, gives one an optimistic approach to life.

Moderate but regular aerobic exercises such as walking, swimming, gardening, and dancing can help obese individuals lose weight, provided that it does not exceed their cardiovascular capacity as well as muscle strengthening, bone strengthening and stretching.

Regular exercise reduces the demand for medication by 20% in people with diabetes and checking the blood glucose levels before and after exercise can be a motivator to continue the exercise regimen.
