Not if you’re a shrew!
A shrew is a compulsive eater with an incredibly fast metabolism. In fact, if several shrews are confined without food, the hungriest will eat the others and finally itself!
Anyway, if you’re not a shrew you can’t eat high-fat or high-sugar foods and lose weight, unless you eat it as an occasional treat.
