Don’t Underestimate Sleep in Weight Loss

Posted In: Resource By Rob Ziltzer MD. FACP

Very few people get the 7 hours of sleep required for optimal health. They likely do not understand how sleep deprivation is affecting their health. As health care providers, we have an opportunity to make a significant impact in our patients’ lives without prescribing medications. [Read more]

It has been previously shown that 5% weight loss leads to a 50% reduction hypertension and diabetes risk, or 15 pounds for a 200 lb. individual. Long term weight loss is difficult as it leads to compensatory reduction of Leptin, which reduces metabolism and increases appetite at the level of the hypothalamus. Also, weight loss causes an increase in baseline and peak levels of the appetite stimulating hormone ghrelin. These changes persist for at least one year, and likely lifelong. [Read more]

Phentermine was approved for use in 1959 and for a period of 12 weeks. As obesity has been identified as a chronic disease, the long term use of phentermine has become mainstream amongst physicians who practice full-time obesity medicine. 97% of obesity medicine specialists indicate phentermine is their drug of choice among the current medication options available. Reasons for this include efficacy, safety, tolerability, low cost and low addiction potential. Despite this, concerns regarding safety and addiction potential have continued to limit the use by some physicians. [Read more]



Are 800 calorie diets safe?

It seems nearly everything we learned about obesity in training was wrong if we were taught anything at all. Medical schools and residencies teach the essentials of nutrition for the critically ill patients. When someone is hospitalized, they need adequate nutrition for healing: protein, essential fatty acids, electrolytes, vitamins, minerals, trace elements and water for recovery and healing. Then when we began outpatient medicine, we were flooded with patients with obesity and its consequences of diabetes, hypertension, hyperlipidemia, sleep apnea, fatty liver disease, cancers, and arthritis. Many of those conditions resolve with weight loss. Unfortunately, we were ill prepared to manage the underlying disease of obesity. If we had the knowledge, we never had the time to dedicate during a busy office visit to implement a successful weight loss plan. That is why the specialty of obesity medicine exists. [Read more]

Is Junk Food Marketing Causing Obesity?

Posted In: Obesity Medicine By Rob Ziltzer MD. FACP

As it turns out, food ads may play a huge role in obesity. A new German research study demonstrates that looking at pictures of salty or sweet foods (such as Viennese Schnitzel, ice cream or pizza) causes an increase in grehlin, a hunger hormone. Pictures of pianos, bikes or shoes did not have the same effect. This is the first time pictures of junk food pictures have been shown to cause immediate adversity. So we should take notice!
