Answer 2

Exercise has been shown to improve your mood and decrease feelings of depression, anxiety and stress (2).

It produces changes in the parts of the brain that regulate stress and anxiety. It can also increase brain sensitivity for the hormones serotonin and norepinephrine, which relieve feelings of depression (1).

Additionally, exercise can increase the production of endorphins, which are known to help produce positive feelings and reduce the perception of pain (1).

Furthermore, exercise has been shown to reduce symptoms in people suffering from anxiety. It can also help them be more aware of their mental state and practice distraction from their fears (1).

Interestingly, it doesn't matter how intense your workout is. It seems that your mood can benefit from exercise no matter the intensity of the physical activity.

In fact, a study in 24 women who had been diagnosed with depression showed that exercise of any intensity significantly decreased feelings of depression (3).

The effects of exercise on mood are so powerful that choosing to exercise (or not) even makes a difference over short periods.

One study asked 26 healthy men and women who normally exercised regularly to either continue exercising or stop exercising for two weeks. Those who stopped exercising experienced increases in negative mood (4).

Some studies have shown that inactivity is a major factor in weight gain and obesity (5, 6).

To understand the effect of exercise on weight reduction, it is important to understand the relationship between exercise and energy expenditure.

Your body spends energy in three ways: digesting food, exercising and maintaining body functions like your heartbeat and breathing.

While dieting, a reduced calorie intake will lower your metabolic rate, which will delay weight loss. On the contrary, regular exercise has been shown to increase your metabolic rate, which will burn more calories and help you lose weight 

Additionally, studies have shown that combining aerobic exercise with resistance training can maximize fat loss and muscle mass maintenance, which is essential for keeping the weight off
