I have a different approach for weight loss. The most important thing that will affect your weight greatly is diet. Multiple studies have shown calories in calories out tracking is inefficient and to lose weight, one must pay attention to the portion of macro nutrient in the food. High carbohydrate consumption should be followed with high fiber consumption. This is to prevent the increase of an anabolic hormone called insulin which in high concentration may lead to hunger and weight gain. That's why it is easy to lose weight when the portion of carbohydrate is minimal (less than 70g per day).

Exercise is an important component to keep basal metabolic rate high which can stimulate weight loss. Even though exercise has been proven to cause negligible weight loss in multiple studies, but the right kind of exercise such as weight lifting can increase lean muscle mass. Muscle has mitochondria which will cause increase in metabolism.

Weight loss is a broad topic and there are a lot of factors which can contribute to said, weight loss. So good luck in researching, educating people to stay healthier. Even though you are not a doctor, does not mean you can't share what you know. Check out the latest research to protect yourself from outdated piece of information and you're good. Kudos.
