### SAMI INKINEN QUOTES FROM THE INTERVIEW

**“Structure allows flexibility and spontaneity.”**

— Sami Inkinen

**“Mood follows movement and motion.”**

— Sami Inkinen

**“The biggest secret is saying no to 99 percent of the things that many people consider ‘normal’ so what you care [about] gets done.”**

— Sami Inkinen

**“Truck drivers, their concept of a lunch is McDonald’s. We can’t tell them, ‘Oh, here’s the list. Go shop Whole Foods or Erewhon, and then go home and cook at home.’ It’s like, ‘Okay, McDonald’s it is. We’re going to reverse your diabetes on McDonald’s diet.’ And by the way, we do that.**“

— Sami Inkinen

**“The adherence of Virta patients, again, which are real Americans, not Samis, real Americans, is twice as high at one year as taking a GLP-1 drug. We have 83 percent adherence retention of patients at one year. And look at any of the publicly available data: people stick to GLP-1s like 40 percent, maybe 50 percent, 30 to 50 percent.”**

— Sami Inkinen

**“GLP-1s 100 percent affect your appetite. They change how much you eat, so you eat less, but they alone don’t change what you eat. … And if you don’t change what you eat, you’re not going to be perfectly or even optimally metabolically healthy.”**

— Sami Inkinen

**“Type 2 diabetes can be reversed systematically, not miraculously. And so hopefully I can be a messenger of hope that these conditions are reversible, especially after I already disclosed that I used to live thinking it’s your fault, it’s your fault, you are just lazy, you don’t have the willpower. But that’s not true. Nobody gets these things because they’re lazy or they decide. It’s because of our food environment. And the food environment kind of slowly but surely poisons us. But if you know a few little tricks and changes, you can actually turn back the clock.”**

— Sami Inkinen

**“The love language of American capitalism is dollars. And so when you can help someone else to make money, you’re going to be very, very successful.”**

— Sami Inkinen
