The speaker (Jim Katsoulis) argues that diets fail because they omit the essential "mindset" element needed to create lasting behavioral change. Diets typically instruct what to do but do not teach how to get yourself to follow them, leaving people to rely on willpower that eventually fades. The lasting solution, he says, is to learn to "think like a naturally thin person": changing self-talk and how one thinks about habits and food, not just learning actions.

The reason the diets haven't helped you lose weight is because they're missing the key ingredient needed to create genuine change, which is the mindset piece. The diets are always telling you what to do, but they never show you how to actually get yourself to do it. So that leaves you using the one tool that you have, which is your willpower. And you try and force yourself to follow the plan. And it'll usually work for a little while until you get sick, bored or distracted. And then the willpower fades and you go right back to acting how you always did. So the real secret to not only losing the weight but being able to live the rest of your life at your goal weight is to learn how to think like a naturally thin person. Knowing what to do is not enough. You need to practice thinking thinking like a thin person how you think about yourself, how you think about your habits and how you think about food.
