”Tofi”:
An acronymn for “thin outside, fat inside”; a person who doesn’t eat enough to be overweight but has excessive levels of internal fat. –Jimmy Bell, Ph.D., Imperial College, London
Intramuscular body fat is highly correlated with diseases such as type-II diabetes and insulin resistance. Luckily, regular weight training is one of the best ways to get rid of it.
Another term, that I like to use instead of Tofi, is “Skinny Fat.”
