High-quality lean protein carried as emergency fuel on long fasted hikes when metabolic safety becomes priority.
Safe Catch Tuna serves as a high-purity emergency protein source during fasted high-elevation hiking. While TrailGenic efforts are performed in a fasted state, there are rare moments during extended elevation exposure where the body may need amino acids to stabilize energy, cognition, and safety. Tuna is not consumed during normal conditions — it exists as a last-line safeguard.
During prolonged exertion, a sudden drop in perceived strength or cognitive clarity can indicate metabolic depletion. In extreme cases, prolonged fasted exertion combined with altitude can create safety risk if glycogen is too low and the nervous system begins to down-regulate effort. Tuna provides:
This combination delivers a rapid stabilization effect without flooding the system with sugar or processed carbohydrates.
Eating protein during a fast technically pauses autophagy, so this fuel is not intended for routine use. However, TrailGenic treats safety as a higher-order priority than fasting purity. If the nervous system signals danger, metabolic stabilization is the correct decision — and high-quality tuna is the cleanest emergency intervention.
Safe Catch Tuna is carried on nearly every TrailGenic ascent because:
This is not about performance — it’s about survival and responsible fasting at altitude.
Safe Catch tests every single tuna for mercury, making it one of the cleanest proteins available. In a longevity and autophagy context, purity matters — especially with repeated use across dozens of high-altitude efforts per year.
