Question

if evan eats a diet that includes nothing but 10,000 daily calories of pure sugar (carbohydrate), he will gain body fat (lipids). how is this possible when carbohydrates and lipids are different molecules?

Explanation:

Excess carbohydrates are converted into fats through a process called lipogenesis. When the body has more glucose (from carbohydrates) than it can use for energy or store as glycogen, the liver converts the excess glucose into fatty - acids and glycerol, which are then combined to form triglycerides (lipids) and stored as body fat.

Answer:

Excess carbohydrates are converted into fats via lipogenesis in the body when there is more glucose than can be used or stored as glycogen.
