The old calories in/calories out model states that if you expend more energy (i.e exercise) this will increase your energy out and help to lose weight (obviously if your energy out is lower than energy in). Gary Taubes argues that this is flawed because it is based on the assumption that our bodies will not increase our appetite or decrease our metabolism to compensate, and numerous studies show that our bodies do this. Therefore, these two factors are not independent of each other, and by that I mean you can’t increase your energy out component without directly influencing your energy in (more hunger, metabolic rate reduces).
Gary Taubes argues that rather than exercising to lose weight, thin people tend to exercise because they have access to more energy. That is their bodies are not hoarding all the fat into fat cells and therefore hijacking energy from the food we eat. Now that I am on low carb (< 20g a day) theoretically my body is now, finally, accessing my fatty reserves, and trust me that would be similar to when they first struck oil in Texas – it’s a bonanza of untapped energy.
Regardless, I have found that my energy levels may have increased as a result. I say may because I don’t notice that I have more energy, what I have noticed is that tasks that involved a lot of mental persuasion to do are now been done with little thought. For example, washing the car, cleaning the house, walking to work etc. All of these I would have tried to avoid before because it seemed like too much work (yes I know how sad that sounds), but now I am able to do them without any mental blockages. Additionally, I am able to do more of them for longer before I become tired.
Now this could easily be attributed to the placebo effect – my diet is working and so I feel more uplifted and so more energetic. I would not be confident enough to argue this isn’t the case. So I blog about this with that caveat in mind. The good news is I am dropping weight like no bodies business. Just last night I dropped another 0.9 pounds giving me a grand total of 11.2 pounds lost since last Saturday. I am still very dumbfounded at how easy this is.
