Use this calculator to easily calculate the thermic impact of food (TEF), a.k.a. thermic result of feeding, a.k.a. diet-induced thermogenesis (DIT) for diets through different amounts of calories and also a various macronutrient mix. Calculates TEF in kCal and also as percent of TDEE/TEE based on a mentioned mix that carbohydrates, fats and proteins.

how to usage the Thermic result of Food calculator?

Using the calculator to calculation the thermic result of food in kiloCalories and kiloJoules as well as a portion of power intake or complete daily energy expenditure (TDEE) is fairly straightforward. Start by picking how you desire to get in the macronutrient balance information: as percentages (e.g. 25%), proportions (e.g. 0.25) or in state of number of kCal or kJ (e.g. 1,000 kCal, 4,184 kJ). Then enter the macro info for proteins, carbohydrates and fats.

If you push "calculate" at this suggest the device will only output thermic impact of food together a portion of complete energy intake. Girlfriend can select to get in the full energy entry in kCal or kJ in i beg your pardon the TEF calculator will also output the thermic impact of food in kCal and kJ. If you additionally input the full daily energy expenditure it will output TEF as a percentage of TDEE together well.

What is Thermic impact of Food?

Feeding root cause a climb of metabolic rate because of the processes of digestion, absorption, and also short-term warehouse of macronutrients. In other words, that takes power to procedure and save energy. This is what is referred to as the thermic impact of food, a.k.a. The thermic result of feeding or diet induced thermogenesis. The state "thermic effect of food" and also "thermic result of feeding" room equivalent and both conveniently abbreviate to TEF. The various other term, "diet-induced thermogenesis, is abbreviated together DIT.

Contrary to part statements, there appears to be no far-reaching difference in the thermic effect of food bewteen lean and also obese human being consuming the exact same amount of calories through the exact same macronutrient composition. In fact, the impact increases linearly v caloric intake and is independent that leanness and also obesity <2>.

On the other hand, the TEF/DIT impact can be broken down by nutrient kind as the energy required to process and store different macronutrients varies depending upon the kind of macronutrient being consumed. Proteins require multiple times much more energy to procedure and save than execute both fat and carbs. Fat has actually the least contribution come thermic effect of food. As result of this, the all at once thermic result of feeding varies depending on the macronutrient mix the the person"s diet.

While that is commonly assumed the the thermic result is around 10% of energy intake, that is a bad approximation in many cases. Because that example, the is around true just for a balanced diet the 50% carbohydrates, 25% proteins, and 25% fats (10.63% of energy intake), but varies in between 6% and also 13% in some dietary mixes, as portrayed below:

impact of Macronutrient Balance on Diet-Induced Thermogenesis

The table listed below presents worths for thermic effect of feeding (TEF) as power value and as percent of full intake because that a couple of common dietary choices. All tabulated worths were calculated making use of this thermic impact of food calculator.

Thermic effect of food for various macro proportionsDietMacro Mix (C/P/F)TEF (kCal / day)TEF together % of Intake
High Carb60% / 25% / 15%27811.13%
DASH Diet55% / 27% / 18%28311.33%
Moderate Diet50% / 25% / 25%26510.63%
Zone Diet40% / 30% / 30%28111.25%
Low Carb30% / 40% / 30%32513.00%
Keto Diet10% / 15% / 75%1596.38%

In the above table the thermic result of food is calculated based on an input of 2,500 kCal every day.


Thermic result of Food Equation

The formula used in this calculator is from room 2009 <1> that cites the from a work-related by Blaxter K.: "Energy metabolism in Animals and Man" and it is:

*

Where the three alphas (αF, αP, αC room the short-lived thermic effect coefficients because that fat, protein, and also carbohydrates, respectively, and also FI, PI, and CI represent the intake amounts or proportions of the 3 macronutrient types.
