Whether you whip up an omelet every morning or merely subsist on coffee, everyone has a meal they turn to when trying to fuel a productive day. But for some expert insight into the matter, Business Insider reached out to various entrepreneurs, business owners, and best-selling authors to get a better idea of what a "productive" meal looks like. From Bulletproof coffee in Silicon Valley to the standard hard-boiled egg and English muffin, here's what three real CEOs eat for breakfast when they have a 12-hour day ahead of them:
"I like to start the day with a hard-boiled egg and sometimes a whole-grain English muffin with peanut butter. But all of this wouldn’t work without a large coffee, which is necessary fuel for any entrepreneur and new parent, like myself."
"I start my day with a vanilla protein milkshake, purified omega-3 fish oil, amino acids, and glucosamine for joint health. Add a double espresso and mid-morning protein bar … and I’m ready to seize the day."
"I prefer caffeine or adrenaline to start my day. A Bulletproof coffee with grass-fed butter and Brain Octane hits the spot. It gives me a quick source of energy from fat instead of sugar."
