Investor Mark Cuban said in 2014 that his breakfast consists of a cup of coffee and two cookies from a company called Alyssa's Cookies.
The cookies are high in protein and fiber, and low in carbs, according to the company's website.
Cuban inveested in the company in 2012 after its cofounder sent him a sample box of the cookies with a letter asking him to invest $50,000 in the company for a 25% stake, CNBC reported.
"I don't just eat them, I live on them," Cuban says on his company website. "It is not an exaggeration to say there are days when I have had them for breakfast, lunch, and dinner."
His favorite type of cookie is the Healthy Oatmeal Bite, according to the company.
