I consider these the “Big 4”

Exercise

A gym session or brisk 30-minute walk can help. Physical activity stimulates various brain chemicals that may leave you feeling happier and more relaxed. You may also feel better about your appearance and yourself when you exercise regularly, which can boost your confidence and improve your self-esteem.

Nutrition

Eating a diet rich in some vegetables and fruits as part of an overall healthy diet may protect against certain types of cancers. Diets rich in foods containing fiber, such as some vegetables and fruits, may reduce the risk of heart disease, obesity, and type 2 diabetes.

Genetics

Genetic variants influencing the effectiveness of weight loss strategies.

Sleep

Sleep makes you feel better, but its importance goes way beyond just boosting your mood or banishing under-eye circles. Adequate sleep is a key part of a healthy lifestyle and can benefit your heart, weight, mind, and more.
