Will Certain Foods Actually Burn Fat?

The idea is a compelling one: If you eat the right foods, your metabolism switches into overdrive and your body magically starts depleting its fat stores.


So, the theory goes, if you’d just eat more egg whites, or garlic, or grapefruit, you’d lose the weight you’d want.


Unfortunately, your body just doesn’t work this way.


Yes, carbohydrates, fat and protein can increase your metabolism (your body’s ability to convert food to energy) slightly, but it’s still a relatively small increase in the long run.


The fact is that when you eat any food, your metabolism increases to digest and use the food’s kilojoules for various functions. This is called the “thermic effect” of food – and the effect is always temporary. No one food can elevate your metabolism for extended periods. Interestingly, though, some recent data suggests that while certain foods may not “burn” fat, you may not absorb as many kilojoules from them as once thought.

For example, Dr David Baer, from the US Department of Agriculture, studied the measured energy value of pistachios in the human diet.


Baer’s team found that the amount of kilojoules study participants absorbed from pistachios was actually five per cent less than the number of kilojoules on the nutrition facts panel for the pistachios.


No, that’s not a substantial amount you should obsess over, but know this: your body doesn’t absorb every kilojoule from the food you eat (some just pass through you undigested) particularly if that food contains fibre and/or protein.


Does this mean that eating pistachios will burn fat? Of course not.


But it lends evidence to the concept that the amount of kilojoules you think you’re eating may not actually be what you’re eating.


Other foods have followed suit with the pistachio study: apples, carrots, sweet potatoes and beef, are some examples. Scientists are still sorting out exactly what role protein and fibre play in non-absorbable kilojoules.


What does this all mean for you?


1. Don’t believe the hype about certain foods possessing “fat-melting” properties.


2. This is just another reason to add more fibre- and protein-rich foods to your diet.


Try to include meat or seafood, vegetables and fruit, as well as complex carbohydrates at each meal. Though this won’t turn you into a metabolic machine, it will fuel your body and help you consume fewer kilojoules from those foods you eat.


And it’s no coincidence that those exact same foods help to fuel muscle growth, fight disease and keep you fuller for longer so you eat fewer kilojoules over the course of a day. Bonus!
