Built on Leaves
The strongest primate doesn’t get power from steak.
Power does not require meat.
Meet the largest primate on Earth — powered, almost entirely, by plants.

Two kinds of strong.
Humans train specific lifts — pressing, squatting, deadlifting — and get very good at them.
Gorillas are built for climbing, pulling, carrying, and moving a huge body through forest.

What a gorilla is built for
Big body
Hundreds of pounds of muscle and frame.
Long arms
Arms longer than legs — reach and pulling power.
Powerful upper body
Built for climbing, hauling, and holding on.
Constant movement
All-day foraging and travel through the forest.
Mostly plant diet
Leaves, stems, fruit, roots — plus a few invertebrates.
A different gut
A digestive system built for fibrous plants, not a copy of ours.
A gorilla is not a human nutrition plan. But it does break the myth that meat is the only path to muscle.

- Western Lowland GorillaGorillas are the largest of the great apes; adult males average 300 lb and up to 500 lb, with an arm span of 8 feet and arms longer than legs. Diet is leaves and stems of herbs/shrubs/vines plus fruit; they get some protein from invertebrates. Adult males eat about 45 lb of food per day.
- GorillaGorillas are the largest of all primates; males weigh 300–400 lb. Almost everything a gorilla eats is plant material — leaves, stems, fruits, seeds, roots — plus ants and termites. An adult male eats up to 40 lb of food each day.
