Three factors are externally responsible for obesity and obesity control. These are:
Nutrition: Certain foods, such as refined carbohydrates and unsaturated fats, contribute the most to obesity
Medicine: Certain prescription medicine, including anti-depressants, steroids, contraceptives, medications for diabetes, hypertension, migraines, seizures, bipolar disorder, allergies, insomnia, and a host of others, are associated with weight gain.
Sleep: Disrupted sleep or less than 7 hours or more than 9 hours can lead to obesity. Difficulty in breathing can also be a reason for disturbed sleep.
Obesity is a complex disease. It appears as a polygenic condition. It is affected by environmental factors (mainly unbalanced dietary patterns and physical inactivity). We will have to take into account genetic factors in the fat reduction process. These are associated with a negative energy balance. (Martinez et al., 2008)
Many people are looking for a silver bullet to reduce weight with the least effort quickly. They try a variety of weight loss supplements and medications. We have reviewed the available supplements and have found that their impact is, at best, can be marginal.
Losing weight is best achieved when we proceed systematically. As others have also said, weight loss is achieved by working up a negative energy balance. It is done through lifestyle modification and not teas and supplements.
