Question 1

What is the Thermic Effect of Food (TEF)?

Answer 1

TEF is the amount of energy expenditure above the resting metabolic rate due to the cost of processing food for use and storage.

Question 2

What contributes to the Thermic Effect of Food (TEF)?

Answer 2

TEF is influenced by the composition of food, with protein-rich foods having the highest TEF followed by carbohydrates and fats.

Question 3

How does the Thermic Effect of Food (TEF) relate to overall metabolism?

Answer 3

TEF is a component of metabolism, contributing to total energy expenditure along with basal metabolic rate and physical activity.

Question 4

What is the approximate percentage of total energy expenditure that the Thermic Effect of Food (TEF) accounts for?

Answer 4

TEF generally accounts for about 10% of total energy expenditure.

Question 5

TEF - Initials

Answer 5

Question 6

How does the Thermic Effect of Food (TEF) influence weight management?

Answer 6

Higher TEF can lead to increased energy expenditure and thus may contribute to weight loss or management.

Question 7

Can the Thermic Effect of Food (TEF) be modified?

Answer 7

Yes, TEF can be influenced by factors such as diet composition, meal frequency, and individual metabolic factors.
