Obesity and physical activity, how to lose weight?
Obesity is one of the most common health problems today. With changes in consumption and transportation patterns, it is on the rise worldwide. Added to this is the evolution of communication technology, which encourages sedentary lifestyles. Overweight and obesity can have serious impacts on health. Indeed, being obese means exposing oneself to cardiovascular disorders. It is also likely to develop diabetes. In the worst cases, obesity can lead to death. Losing weight is therefore an obligation for people suffering from obesity. And to do so, they must opt for sports. How then can obesity and physical activity be combined to reach the ideal weight?
When do we talk about obesity?
Obesity is the imbalance between the amount of fat and the amount of muscle in the body. It is caused by the imbalance between the calories ingested and the calories expended, the former being greater. The difference between the two is stored by the body and leads to obesity over time.
Either way, a few extra pounds doesn't make you obese. In fact, obesity is determined by calculating your Body Mass Index or BMI. The calculation of this index is very simple, simply divide the mass expressed in kg by the height expressed in m and squared. Thus, a BMI above 30 kg/m2 corresponds to obesity. Here again, a ranking has been carried out by scientists to better identify the different types of obesity.
A BMI between 30 and 34.9 corresponds to moderate obesity. Between 35 and 39.9, we speak of severe obesity and above 40, it is morbid obesity.
Obesity-related risks
Having excess fat can have a negative impact on a person's health. Indeed, obesity increases the risk of various cancers (digestive system cancer, breast cancer, ...), diabetes, liver disease, osteoarthritis and gout. Obesity is also one of the risk factors for high blood pressure, excess fat in the blood and sleep apnea syndrome. When morbid, obesity can lead to death.
The effects of physical activity on obesity
When obesity threatens your health, it is important to do everything possible to lose the extra pounds and return to your ideal weight. To lose weight and lose weight, you've often heard that exercising is the best solution? The question then arises as to the main effects of physical activity on obesity. And you will be surprised to find out the answers to this question.
In fact, sport contributes to weight reduction when it comes to obesity. Also, it improves the overall health of the person concerned. By moving, you act by promoting the proper functioning of your respiratory and cardiovascular systems. Another positive effect of physical activity is the prevention of regaining the few pounds lost after a diet. Regular physical activity can help you control your weight and prevent it from coming back.
Sport also promotes weight loss by reducing abdominal fat, visceral fat and the amount of fat massage contained throughout the body. However, the activity in question must meet certain conditions for it to be more effective:
- Physical activity must be carried out in an intense manner
- Opting for aerobic training is the best decision to make to reduce subcutaneous fat
- Making a calorie restriction also helps to promote the effect of sport in relation to the loss of fat mass. So don't hesitate to ask for the help of a nutrition professional to set up an adapted diet.
What kind of physical activity should I do?
Physical activity therefore helps to increase energy expenditure and burn fat. However, it is important to make sure you do not lose lean body mass, as this helps you control your weight through energy consumption. So, to combine obesity, physical activity and weight loss, make sure you combine aerobic-dominant activities with resistance exercises such as strength training to preserve your muscles.
It is also recommended to do moderate physical activity for 45 to 60 minutes in order to expend between 300 to 500 kcal each session. And to choose the right activity for your health, you should seek professional advice. In fact, you may be suffering from back, hip and joint pain.
