The Claim

The human body is capable of producing adequate glucose via endogenous gluconeogenesis to satisfy metabolic requirements, including during periods of high energy expenditure such as endurance training, which implies that dietary carbohydrates are not essential for maintaining metabolic function.

How it works
0 studies reviewed
In plain English

Your body can make all the sugar it needs, even when you're doing intense exercise like marathon training, so you don’t actually have to eat carbs to stay healthy.

See the scientific wording

The human body endogenously produces sufficient glucose through gluconeogenesis to meet metabolic demands, even under conditions of high energy expenditure such as endurance training, rendering dietary carbohydrate intake non-essential.
