Subjects will be provided with either a HFLC diet or a LFHC diet to consume for 2 weeks. These diets will be designed to meet subjects energy requirements. After consuming the diet for 2 weeks (diets will comprise of 3 meals and 3 snacks per day), subjects will return to the laboratory for the second study visit. Subjects will be provided with a set of visual analogue scales to complete on days 4, 8 and 12 of the intervention period. Subjects will then return to their habitual diets for 2 weeks, before completing the second intervention.
