Explanation:
It is true that according to research the genes that affect energy balance in the body effectively promote energy intake and weight gain but are inefficient to promote energy expenditure and weight loss. This is because it is likely to be a polygenic condition such that there are numerous genes in interaction. Therefore the genes that promote energy intake and weight gain are insufficient to promote weight loss and energy expenditure which is the required energy to carry out physical activities such as breathing, exercising, etc.
