Are you avoiding carbs like the plague, convinced they’re the enemy of metabolic health? What if cutting out too many carbs is actually making things worse? In this episode of ReInvent Healthcare, Dr. Ritamarie Loscalzo exposes one of the biggest misconceptions in the keto community—the belief that all carbs are harmful.

She breaks down why non-starchy vegetables are not the enemy, but rather an essential part of supporting metabolic health and lowering A1C. Many people following a strict keto diet drastically reduce their carb intake, often to the point of avoiding nutrient-dense vegetables. While this may show short-term benefits, what does it mean for long-term blood sugar control, insulin sensitivity, and overall health?

If you’ve been told to limit yourself to just a few grams of carbs a day to stay in ketosis, this episode will challenge what you think you know about carbohydrates and blood sugar.
