When you want to lose weight, what is the weight you want to lose made of? The obvious answer is 'fat'. Fat can refer to either the biochemical substance that we call fat or to the tissues that stores this substance. The storage tissue is called 'adipose tissue'.

Adipose tissue consists of specialised cells called adipocytes that contain a large globule of the biochemical substance. Biologists refer to the globule as the 'lipid droplet' made of triglyceride. Triglyceride is the substance you are actually talking about when you say you want to lose some weight.

Losing fat depends on the total balance between the amount of fat you burn and what you store over time. Storing fat is something your body does all the time; even while you're in an energy deficit, your body will switch between storing and burning fat. So to lose fat, you have to keep fat oxidation or fat burning at a higher rate than fat storage.
