035: Which Is The Best Energy Source: Carbohydrates or Fat

Simple, Healthy Choices for Weight Loss

In this episode, Dr. Steve explores the comparative benefits and downsides of carbohydrates and fats as energy sources. He dissects the processes of energy storage and release in our bodies, sheds light on the role of fats, and reveals the potential harm of carbohydrate-rich diets. The episode concludes with an emphasis on low-carb diets, the risks of processed foods, and the advantages of natural, locally-sourced nutrition.

[00:01 - 05:40] Understanding Calories and Energy Sources

What is a Calorie?

Adenosine triphosphate (ATP) is derived from either ketones from fat or glucose from carbohydrates.

Proteins and fats keep you feeling full for longer than carbohydrates, which are quickly stored as fat

Glucose (from carbohydrates) produces fewer ATP units than ketones (from fats)

[05:41 - 14:52] Energy Sources: Carbohydrates vs. Fat

Carbs break down to glucose, which gets packed together and stored as glycogen, filling 1% of each muscle cell and 10% of the liver.

Low-fat diets since 1977 led to obesity and diabetes surge.

Glycolysis results in harmful free radicals; antioxidants are required for neutralization.

High-carb diets cause diseases, which leads to increased intake of antioxidant-rich foods to try and counter.

Diabetes is NOT just a glucose issue, but mainly a problem with too much insulin, which can ONLY be managed with nutrition.

[14:53 - 24:37] The Role and Importance of Fats in our Bodies

Fats are broken down into fatty acids, which are converted into energy-rich ketones in our cells.

Contrary to common misconceptions, both fat and cholesterol play crucial roles in hormone production and cell membrane formation, as well as being our God-intended, main fuel source for our bodies.

Burning fats is more efficient and cleaner than burning carbohydrates, making it a preferred energy source.

White fat is an energy reserve and hormone provider, while brown fat helps regulate body temperature, plays a big part in increasing our metabolism and can aid in weight loss.

[24:38 - 28:50] Closing Segment

High insulin from carbs turns brown fat to white, storing more fat.

Fewer carbs mean lower insulin, which converts white fat to brown, boosting metabolism.

Processed foods contain harmful ingredients that can cause health issues.

Natural and locally sourced foods, alongside water over sugary drinks, can improve health.
