Math? To plan dinner? Isn’t there a better way? Yes there is. Just take a look at your hand. Use your fist, palm, cupped hand, and thumb to practice calorie control – while avoiding the hassle of counting calories
Next, you have to assume that the handbooks, websites, and databases’ calorie estimates are correct. They’re often not. In fact, research has shown they can be off by about 25% because of incorrect labeling, laboratory measurement error, and food quality.
Then, of course, there’s the “calories out” side. Estimating your calorie expenditure each day comes with another 25% measurement error because of the equipment you’re using, laboratory measurement errors, and individual differences.
First of all — on the “calories in” side — you do need to figure out how many calories are in the foods you want to eat. And that takes handbooks, websites, databases and math. Just to plan your lunch.
All you need is the ability to count to two. And your own hand.
