Dr. Bret Scher, MD

bret-scherDr. Bret Scher is a cardiologist practicing in San Diego. He’s hosting The Diet Doctor Podcast, he’s the author of the book Your best health ever!1, and he has a blog and website at lowcarbcardiologist.com.

Dr. Scher’s main focus is on preventing and reversing heart disease naturally rather than putting patients on medication and performing surgery. When he started his own preventative wellness center he was introduced to the whole low-carb world. Being a bit skeptical at first, he was soon convinced by the benefits of a low-carb diet.

In Dr. Scher’s many patients suffering from heart disease, he found that there was a big overlap with cardiovascular disease, diabetes, metabolic syndrome and insulin resistance. It was all very interrelated. When he started treating his patients who suffered from heart disease with a low-carb diet, he could quickly see signs of improvements or even full reversal in all of these diseases.

Dr. Scher is now doing an amazing job hosting The Diet Doctor Podcast. The goal of the podcast is to empower people everywhere to revolutionize their health.

Dr. Scher is also writing news articles, mainly about new scientific studies, and medically reviewing other content.
