When your body gets a boost of the stress hormone epinephrine (like during intense exercise or panic), it starts turning more of your stored fat into ketones — the fuel your brain can use — and this study says it jumps from about 6-7% to 11%.

1992 Aug

The study gave people a specific dose of epinephrine and found that it made their bodies produce more ketones from fat, just like the claim said.

Similar Assertions

When your body releases adrenaline (like during stress or exercise), it speeds up the swapping between two energy molecules called ketones, even if your other hormones aren’t changing—kind of like adrenaline giving ketones a little push to switch forms faster.

When your body gets a surge of stress hormone (epinephrine), it breaks down fat to make ketones—just like when you get a direct fat drip into your vein. This suggests it’s not the hormone itself, but the fat it releases, that actually makes your body produce ketones.
