Total vs. Net Carbs: Dr. Eric Westman on Personalizing Low-Carb Eating

By Published Reviewed by Dr. Tro Kalayjian, DOReviewed

Highlights from a December 8, 2020 Toward Health group coaching conversation with Eric Westman, MD.

This article reorganizes the original meeting recap so its main themes are easier to find. It preserves the guest’s historical comments and Toward Health’s original summary; it does not turn those comments into individualized medical advice.

About the 2020 conversation

Eric Westman, MD, joined a Toward Health group coaching meeting on December 8, 2020. The original recap described him as an associate professor of medicine at Duke University, board certified in obesity medicine and internal medicine, and the founder of Duke’s Keto Medicine Clinic. It also noted his clinical research, professional roles, books, and work with Adapt Your Life. Those credentials and affiliations are reported as they appeared in the historical recap.

The conversation accompanied the release of End Your Carb Confusion, written with Amy Berger, and focused on how carbohydrate targets can vary, how Dr. Westman approaches total versus net carbohydrates, and how people can monitor their response when making dietary changes.

Low-carb eating does not require one identical target

According to the original recap, Dr. Westman did not believe that everyone needed to follow strict ketogenic eating or maintain a deep level of ketosis to benefit from reducing sugar. He described his clinical approach as starting with a defined carbohydrate limit and then personalizing it according to medical conditions, activity, goals, and individual response.

The recap said his book used a checklist of medical conditions and activity levels to help readers select a starting point. It also described adding carbohydrates back in five-gram increments, remaining at each level for one or two weeks before making another change. This was the guest’s historical framework, not a new Toward Health protocol.

Total carbohydrates versus net carbohydrates

During the meeting, Dr. Westman said he generally recommended counting total carbohydrates rather than net carbohydrates. The original recap attributed this preference to his clinical observation that some patients had better results after moving from 20 grams of net carbohydrates to 20 grams of total carbohydrates.

That statement describes the guest’s reported experience. The appropriate intake for any individual can depend on medical history, medications, activity, nutrition needs, and treatment goals.

Track more than the scale

The discussion encouraged participants to pay attention to how they felt, body measurements, and health markers such as glucose, fasting insulin, and blood pressure when changing their carbohydrate intake. The group emphasized that one scale measurement is only a momentary snapshot.

The recap also attributed to Dr. Westman the observation that some athletes may tolerate substantially more carbohydrate.

Low-carb replacement foods can be useful and difficult to moderate

Dr. Westman and Tro Kalayjian, DO, also discussed packaged keto replacement foods. The original recap said both viewed these products as potentially useful for long-term adherence while also recognizing that highly palatable foods can be easy to overconsume.

The conversation extended the same caution to foods such as nuts and dairy. The practical point was to notice whether a replacement helps someone follow their intended plan or instead becomes difficult to moderate.

Key themes from the meeting

  • A low-carbohydrate approach can be personalized rather than treated as one fixed target for everyone.
  • Dr. Westman described why he favored total-carbohydrate counting in his clinical work.
  • The discussion encouraged tracking wellbeing, measurements, and relevant health markers rather than relying only on the scale.
  • Packaged keto foods may be useful in some situations but can become difficult to moderate.
  • The original recap compared the language of smoking cessation and food addiction; that analogy remains an attributed historical statement.
