Dr. Bret Scher, MD

bret-scherDr. Bret Scher is a board certified cardiologist and lipidologist practicing in San Diego. He’s our full-time Medical Director, writes medical blogs, reviews guides and news stories for medical accuracy and hosts The Diet Doctor Podcast.

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.

He is also the author of the book Your best health ever!1, and he has a blog and website at lowcarbcardiologist.com.
