The fact that fat molecules store energy for fat cells until they are needed is a universal truth in medicine. Triglycerides is the moniker we’re probably most familiar with for these molecules because they are made up of three fatty acids connected to a glycerol. But scientists have long hypothesized that these molecules shift slightly while they are being kept. Even some circumstantial evidence points in that direction. Instead, they are subject to a process called “triglyceride cycling,” a process by which the body breaks these molecules down and reassembles them into new triglycerides.
