"I could never gain much weight. I've always had a fast metabolism"

Marc Wallice's quote recommends that he has actually always had difficulty gaining weight due to his quick metabolic process. This might be due to a variety of elements, such as genes, lifestyle, or diet plan. It is possible that his body is naturally more efficient at burning calories than the average individual, making it hard for him to gain weight. It could also be that he has an active way of life, which needs more energy and burns more calories than a sedentary way of life. Furthermore, his diet plan might not be supplying him with sufficient calories to put on weight. Whatever the cause, it is clear that Marc Wallice has always had problem gaining weight due to his quick metabolism.
