There is no amazing secret that lies behind losing weight. It comes down to one simple formula:
Calories in (Eaten) needs to be less than calories out (Used through exercise) which creates what is known as a ‘calorific deficit’.
As long as you are following this formula to create a calorific deficit you will lose weight. Obviously things get more advanced than this but that tends to matter more for people taking part in body aesthetic competitions or those really wanting to fine tune their appearance. However for general weight loss for the basics are all that matters.
