SAMA HOOLE: But when you eat seed oils, you're consuming the same fats hibernating animals use to shut down their metabolism for winter.

Bears, ground squirrels, and hedgehogs deliberately gorge on high-PUFA foods before hibernation.

Nuts, seeds, high-linoleic acid plants.

Bears, ground squirrels, and hedgehogs deliberately gorge on high-PUFA foods before hibernation. Nuts, seeds, high-linoleic acid plants. Why? PUFAs lower metabolic rate and body temperature. Perfect for months of torpor. This is evolutionary strategy: Consume fats that slow you down when you need to slow down. You're not hibernating. You don't want lowered metabolic rate. You don't want suppressed body temperature. You don't want torpor. But when you eat seed oils, you're consuming the same fats hibernating animals use to shut down their metabolism for winter. Then you wonder why you: Feel sluggish Gain weight easily Have low energy Can't get warm Need coffee to function You've activated hibernation metabolism. In the middle of summer. While trying to live a high-performance life. Carnivore with high saturated fat does the opposite: Raises metabolic rate (thermogenic effect) Increases body temperature (mitochondrial uncoupling)

Provides consistent energy (stable fuel source) Promotes alertness (ketones for brain) Hibernating animals evolved to eat PUFAs when survival required shutting down. Humans evolved to eat saturated fats when survival required staying active and alert. You're eating hibernation fuel while expecting performance fuel results. The mismatch explains everything. Stop eating like a bear preparing for winter torpor.

Start eating like a human optimised for year-round activity.
