The term TOFI, “thin-outside-fat-inside” is used to describe lean individuals with a disproportionate amount of fat (adipose tissue) stored within their abdomen. The figure to illustrate this shows two men, both aged 35 years, with a BMI of 25 kg/m. Despite their similar size, the TOFI had 5.86 litres of internal fat, whilst the healthy control had only 1.65 litres.
