Summary
This is a common myth that we’re going to completely rip apart, today! Listen in on this research review to better understand the role of insulin, what actually causes obesity, and why you can't blindly take advice in the fitness and nutrition industry.
Background: The carbohydrate insulin model (CIM) states that increasing fat deposition in the body—resulting from the hormonal responses to a high-glycemic-load diet—drives positive energy balance.
Said differently, Diets with a high proportion of carbohydrate elevate insulin secretion and thereby suppress the release of fatty acids from adipose tissue into the circulation and direct circulating fat toward adipose storage and away from oxidation. This altered fuel availability is theorized to lead to a state of cellular ‘internal starvation’ leading to adaptive decreases in energy expenditure and increased hunger.
- Concept: High glycemic load (GL) foods (e.g., high carbs) raise insulin, suppress glucagon, and elicit glucose-dependent insulinotropic polypeptide (GIP) response. This cascade drives glucose into muscle/liver/fat cells for about an hour. At about 3 hours post-meal glucose rapidly decreases to (theoretically) lower than pre-meal state which tells the brain “I need food” and induces a hormone response increasing the drive to eat(ghrelin, etc).
The carbohydrate-insulin model suggests that endocrine dysregulation of adipose tissue is the primary driver of positive energy balance.
Overlap: Both theories suggest that changes in food quality drive weight gain. However, according to the CIM, hormonal and metabolic responses to the source of dietary calories, not merely calorie content, lie upstream in the mechanistic pathway. In the Energy Balance Model (EBM) all calories are metabolically equivalent.

| 0:00.0 | Welcome to the tailored life podcast, the one and only fitness and nutrition podcast that goes way beyond just training and nutrition. |
| 0:14.3 | I'm your host, Cody McBroom, and today with me I have Dr. Brandon Roberts, the chief science officer of tailored coaching method. |
| 0:21.2 | What you were about to hear is this week's research review. |
| 0:24.1 | Every single week, we're going to bring you a short 10 to 20 minute podcast, |
| 0:28.1 | breaking down one specific topic, diving into all the research and teaching as much as possible |
| 0:33.0 | and giving you application takeaways to use this for a science-based approach. |
| 0:38.3 | So stay tuned and get ready for this week's research review. |
| 0:42.2 | All right. |
| 0:42.8 | So today's research review is all about carbohydrates and insulin. |
| 0:46.4 | I'm really excited about this one because I think that it has been kind of used as a |
| 0:52.1 | almost like propaganda or like a fearmongering tactic and really a lot of the |
| 0:56.5 | marketing behind low carb diets keto fasting those kind of things which there's a time in place |
| 1:01.1 | for all of them so there's nothing against those methods but this is some of the marketing that |
| 1:04.6 | has fueled those areas or people quote unquote within the industry and not always for the right |
| 1:10.3 | reason in my opinion. |
| 1:11.1 | So the study we're going to dive into is called carbohydrate insulin model, |
| 1:15.7 | a physiological perspective on the obesity epidemic. |
| 1:18.7 | And as Brandon's going to get into, it's not necessarily a research study, |
| 1:22.2 | but more of, you can correct me on this, |
| 1:24.4 | an interpretation or these authors gathering all the different |
| 1:27.5 | research on this topic and kind of like an article or experiment on it. |
| 1:32.0 | But essentially, we're answering, you know, what is the carbohydrate insulin model and how |
