THERMIC EFFECT OF FOOD

THERMIC EFFECT OF FOOD
•Thermic effect of food (TEF) also known as Specific dynamic
action (SDA), or dietary induced thermogenesis (DIT)
•Apart from resting metabolism and activity energy expenditure,
the body also burns calories every time you eat. This is referred
to as the thermic effects of food or the thermogenic effects of
food.
• In order for you to use the calories from your food, digestion and
processing of nutrients has a certain cost in the form of calories.
As well, it is vital that your body maintain itself in a narrow
temperature range so it has to spend a certain amount of calories
on producing heat.
THERMIC EFFECT OF FOOD
•The thermic effect of food can vary quite substantially. Protein is
actually the hardest food for your body to process and utilise.
Therefore, your body wastes 20 to 30 percent of the calories in
protein in its processing and the release of heat. This is one of
the best reasons to eat sufficient protein with each meal.
•On the other hand, carbohydrates are utilised more efficiently by
the body so that 5 to 10 percent of the calories in carbohydrates
are wasted in processing and heat.
•Fat is the most efficient source of energy for your body, because
only zero to 3 percent of the calories in fat are used in processing
and heat. This is why fat in excess tends to go right onto your
waistline.
THERMIC EFFECT OF FOOD
•This also explains why replacing carbohydrates and fat with more
protein results in more weight loss and less gain in fat
•The thermic effect of food is increased by both aerobic training of
sufficient duration and intensity or by anaerobic weight training
•The primary determinant of daily TEF are the total calorie content
of the meals and the macronutrient composition of the meal
ingested
•TEF is increased by larger meal sizes compared to smaller and
frequent meals
•Thermic effect of food, TEF is very important in weight
management by choosing the right kind of food intake
