7. Elaborate effects of regular exercise on obesity and overweight.

Answer 1

Regular exercise is one of the most important and effective ways to combat obesity and overweight. For individuals who are obese or overweight, regular exercise can help them lose weight, reduce body fat, and improve overall health. Here are some of the effects of regular exercise on obesity and overweight:

1. Burn calories: Exercise, particularly aerobic exercise, helps to burn calories. When individuals burn more calories than they consume, they lose weight. For example, a person who weighs 155 pounds can burn about 260 calories during a 30-minute brisk walk.

2. Boost metabolism: Regular exercise can also help boost metabolism, which is the rate at which the body burns calories. Regular physical activity can help individuals maintain a healthy weight and avoid gaining weight.

3. Build muscle: Exercise helps to build muscle mass, which can help increase metabolism and burn more calories at rest. Additionally, muscle mass can help individuals look leaner and more toned.

4. Reduce body fat: Exercise can also help reduce body fat, particularly visceral fat, which is the fat located around the organs in the abdomen. Excess visceral fat is associated with an increased risk of heart disease and type 2 diabetes.

5. Affect hormones: Exercise can affect hormones that regulate appetite, such as leptin and ghrelin. Regular physical activity can lead to changes in these hormones that help individuals feel full and reduce their appetite.

6. Improve heart health: Exercise can help improve heart health by reducing the risk of heart disease and stroke. Exercise can also help improve blood pressure, cholesterol levels, and other risk factors for cardiovascular disease.

7. Improve mood: Regular exercise can help improve mood and reduce symptoms of depression and anxiety. This can be particularly important for individuals who are overweight or obese, as they may experience negative feelings about their body image.

In conclusion, regular exercise is an important tool in combating obesity and overweight. It can help individuals lose weight, reduce body fat, improve heart health, boost metabolism, and improve mood, among other benefits. To achieve these benefits, individuals should aim to engage in regular physical activity, such as brisk walking, jogging, cycling, or swimming, for at least 150 minutes per week.
