When I first started this journey more than a year ago, I took the concept of energy balance for granted -- calories in should equal calories out for weight maintenance. When I started to change my diet and eat better, higher quality foods and much less junk, I began to question that assumption: Is a calorie just a calorie?
Then I watched the Weight of the Nation documentary series. It said that someone who was previously overweight but not anymore, and who weighed the same as her never-overweight friend, needs fewer calories than her friend to maintain that same weight. theweightofthenation.hbo
An article in the Scientific American issue that I posted about yesterday mentioned that our bodies process foods differently based on a variety of factors, including our gut microbes. (Another topic I blogged about!) So a calorie of a single carrot isn't the same in my gut as it is yours?
And then today I came across an article on Greatist that mentions studies in which the energy balance hypothesis is not supported. It's a good guideline, the author says, but we need to figure out what works for us. He advocates food tracking. greatist.com/health/yoni
So much still left to learn in the realm of nutrition. Fascinating!
