Food contains energy. Exercise requires energy. We feel great when we’re full of energy. But are we talking about the same thing in all three sentences? We aren’t, so let’s clear up the confusion.
Whole nuts have fewer calories than were previously thought. For a few years, research confirming that fact has been trickling in, but now the labels on foods are beginning to change. One KIND bar that was formerly 200 calories, for example, will now be labelled as containing 180 calories.
You can punch your stats into online calculators, tweak your Fitbit settings, and meticulously track every calorie you burn, but no amount of maths can tell you how many calories your body really burns in a day. To get a real answer, you need to do a little self-experimentation.
