It's Not You, It's Your Genes

Obesity is a chronic, remitting-relapsing, neuroendocrine metabolic disease. Studies have shown us that your genetics has more to do with your weight than what you eat or what you do. Some people are able to eat whatever they want without seeming to gain a pound, while others gain quite easily despite nearly starving themselves. Dr. Streff firmly believes that people are not heavy because they lack the will-power to stay lean.


Lifestyle Interventions

Despite our genes, it is possible for us to alter weight through what we eat and we do. However, there must be a purposeful and  specific plan in place to achieve this goal. Dr. Streff uses several tools for managing weight such as dietary interventions, specific activity prescriptions, medications, or surgical interventions when indicated.  He sometimes utilizes tools for behavior modification, such as continuous glucose monitoring  devices (CGMs), especially if he believes there is underlying insulin resistance making weight loss more difficult.


Types of Diets

There is no single diet that is best for everybody, but there may be one diet that is best for a single body. He will offer advice on helping you find a type of diet or macronutrient composition that works for your body to aid in weight loss and restore your health. Each body is different and will respond differently to various foods, but overall broad principles exist that he will help you implement to discover what works.


Calories vs Hormones

Over the last 80 years there has been an insistence on counting calories and treating all macronutrients the same, "A calorie is a calorie" as the saying goes. This theory of weight management is called either the "Conventional Model" or "Calories in Calories Out" (CICO). It's true,  in order to lose weight you have to restrict something. And it's also true, energy into the system must be less than the energy used by the system (otherwise you'll store energy... as fat). However, merely restricting total calories is like using a sledge hammer to pound a finishing nail. Dr. Streff is more a proponent of the "Energy Balance Model" (EBM), which takes into account the complex milieu of hormonal responses directing energy utilization. By eating purposefully for your body and genetic makeup, doing specific types of exercise, and getting proper sleep, one can alter hormonal responses that will favor weight loss.
