There has been quite a bit of debate in the medical and diet community about a recent study entitled Calorie Restriction with or without Time-Restricted Eating in Weight Loss which showed, in essence, that intermittent fasting was no more successful in providing weight loss than caloric restriction.

First, let’s talk about how this study was misinterpreted. Many media outlets interpreted this study as saying intermittent fasting was ineffective. However, other studies have shown this not to be the case. Some thoughts:

A Bit More About Intermittent Fasting

Intermittent fasting is a concept that is derived from thousands of years of religious- and cultural-based rituals. Today, plenty of data show that fasting may have significant health benefits. There are different time intervals for fasting, each of which has its pros and cons but similar health benefits. Of course, fasting cannot be considered the primary or only treatment for obesity or other diseases. Instead, patients should look at intermittent fasting as part of a more significant lifestyle change that includes improving diet through caloric restriction and exercise. Dr. Robine is a fan of the Pesco-Mediterranean diet that prioritizes lean and exceptionally healthy protein like fish and healthy fats, like olive oil, avocado, nuts, and seeds, while deemphasizing saturated fats and simple carbs, like red meats, added sugars, and processed foods.

Ultimately, we can’t look at this study and dismiss intermittent fasting because it doesn’t offer incredible weight loss gains over calorie restriction alone. As such, we continue to suggest intermittent fasting to patients who can benefit from it for their heart and overall health. Intermittent fasting should not be started without the supervision of your primary care physician or cardiologist, as any diet can be problematic if not pursued appropriately.
