Summary of Transcript:
The video discusses the concept of caloric availability, which is the amount of calories that can be extracted from a food versus the total number of calories in the food. Using an example of pure white sugar, the video explains how almost all of the calories in sugar can be extracted as it is our base fuel. On the other hand, the video explains how the caloric availability of a food like sweet corn can be different depending on how it is prepared and eaten. When sweet corn is eaten on the cob, much of it remains undigested and can be seen in the feces. However, if it is converted into cornmeal and made into a tortilla or bread, the caloric availability increases, even though it is still the same food source.

Understanding Caloric Availability in Food: Dr Giles Yeo’s Explanation
In this video, Dr Giles Yeo explains caloric availability in food and how it affects weight loss. Caloric availability is the amount of calories that you can extract from a food versus the total number of calories in a food. This knowledge is crucial for anyone trying to lose weight.
What is Caloric Availability?
Caloric availability is the amount of calories that you can extract from a food. It’s different from the total number of calories in a food. For instance, a candy bar and an apple may have the same number of calories, but the candy bar has a higher caloric availability. This means that the body can break down and extract more calories from a candy bar than an apple.
Caloric availability is influenced by various factors, including cooking and processing methods, fiber content, and nutrient density. For example, cooking food makes it easier to break down, leading to higher caloric availability. On the other hand, fiber and nutrient-rich foods have lower caloric availability since they’re harder to digest.
How Caloric Availability Affects Weight Loss
Caloric availability affects weight loss in several ways. First, foods with higher caloric availability can lead to overconsumption and weight gain. They cause a rapid increase in blood sugar levels, followed by a sharp drop, leaving us feeling hungry and craving more food. This leads to overeating and weight gain.
Second, foods with lower caloric availability can reduce hunger and promote weight loss. These foods are typically rich in fiber and nutrients, which keep us feeling full for longer periods. This means that we’re less likely to snack on junk food between meals or overeat during mealtimes.
Tips for Reducing Caloric Availability
Reducing caloric availability in food can lead to weight loss and better health. Here are some tips:
1. Eat more whole foods: Whole foods like fruits, vegetables, and whole grains have lower caloric availability compared to processed foods. They’re also packed with nutrients and fiber, which keep us feeling full and satisfied.
2. Cook your own food: Cooking your own food gives you more control over the ingredients, cooking methods, and caloric availability. You can opt for healthier cooking methods like steaming, boiling, or grilling, which help preserve the nutrients in the food.
3. Limit your intake of processed foods: Processed foods are high in calories and low in nutrients. They also have a higher caloric availability compared to whole foods. Limiting your intake of processed foods can help you reduce caloric availability, lose weight, and improve your health.
Final Thoughts
In conclusion, caloric availability is an essential concept to understand when trying to lose weight. Knowing which foods have high and low caloric availability can help you make healthier food choices and reduce your overall calorie intake. Eating more whole foods, cooking your own food, and limiting your intake of processed foods are all effective ways to reduce caloric availability and promote weight loss.
