The Weight Loss Scientist: You've Been LIED To About Calories, Dieting & Losing Weight: Giles Yeo

Caloric Availability

The concept of caloric availability challenges traditional views on calorie counting by highlighting how cooking and processing alter the calories we extract from food. Giles Yeoh illustrates this with celery, which contains six calories raw but increases to 30 calories when cooked due to the breakdown of fiber, making more calories available 1. This phenomenon underscores the complexity of calorie counting, as the same food can yield different caloric values depending on its preparation.

Caloric availability is the amount of calories that you can extract from a food versus the total number of calories in a food.

Yeoh emphasizes that while calorie counts provide a rough measure of food intake, they fail to account for the nutritional quality and the actual caloric absorption, urging a focus on food quality over mere caloric content 2 3.

   

Calorie Counting Debate

The debate on calorie counting as a weight management tool reveals its limitations and potential benefits. Steven Bartlett and Giles Yeoh discuss how calorie counting can provide a relative measure for those who consistently eat the same foods, but it falls short when dietary changes occur 4. While some find success with calorie counting, Yeoh warns that it doesn't account for the nutritional value of food, which is crucial for overall health.

If you stick to a purely calorie counting diet...the chances are you probably would lose weight...But how healthy would you be?

--- Giles Yeoh

The conversation also touches on the inadequacy of BMI as a health measure, as it doesn't consider individual differences in body composition and fat distribution 5.
