Thermic Effect of Food


“LOSE 15 POUNDS IN A WEEK BY DOING NOTHING BUT DRINKING THESE DELICOUS SHAKES!”

Does this sound familiar? I’m sure it does-- or something of the sort.  With the growing trend in fad diets becoming ever so popular, catch phrases like these are sucking uninformed consumers in at an alarming rate.  Fad diets are a huge part of the multi-million dollar industry that the supplement industry makes.  
The truth is diet shakes such as the Jillian Michaels Meal Replacement Shakes work only because they are essentially portion control in a glass.  However, what is not taken into effect is the thermic effect of food.   The thermic effect of food is essentially the energy required by the body to metabolize the food you eat.  The effect food has on the body has a huge result on the body’s metabolism and how foods are burned as energy.  
These immensely popular protein shakes do not have the same effect on the body as consuming regular food.  This is because they are already pre-digested, which of course is great for immediate nutrient delivery for post-workout or strenuous activity, but not in the place of having an entire meal. A dieter would greatly benefit from eating actual food in sensible portions. 
Calorie control of course is key to any successful diet.  The body, due to the thermic effect of food, will use much of the calories consumed for digestion leaving a smaller amount to be burned off by the individual from exercise.   When drinking the meal replacement shakes, nearly all of the calories will need to be burned off through exercise because the body does not need to “work” to burn off the calories consumed from the shake.  Many people do not realize the value of real food, and think that by drinking only shakes they will be able to lose weight.  What they don’t realize is that by eating real food, they will feel satiated longer and won’t have to resort to intermittent snacking throughout the day, which lowers caloric intake.   Learn more about the thermic effect of food here.

  1. This is such a hot topic in the health science industry. I like that you went into full description of the thermic effect of food and what it does to our body. I did not realize that protein shakes were already pre-digested and that is the reason our body can easily absorb the nutrients. You did an excellent job at emphasizing how individuals trying to lose weight need to eat real portion controlled food. This is crucial advice that is so regularly misunderstood for those individuals trying to lose weight.
