Hey Fit Family!
Does Body Fat just disappear into thin air?
If not, where does it go?
When we “lose” body fat we lose it from our bodies, but the confusing part is that it doesn’t just disappear.
What happens is that when we eat less calories than we need our body is forced to use stored energy.
We oxidize or “burn” body fat to get the chemical energy from the bonds that hold the fat together, but the carbon, hydrogen, and oxygen that make up that fat are dissipated back into the environment as carbon dioxide and water.
Thus, we lose the vast majority of our body fat via exhaling carbon dioxide from our lungs and then excreting the water via sweat and other bodily fluids .
When you understand this concept it becomes easier to see how it is possible for people to lose massive amounts of body fat eating only ice cream, twinkies, potatoes, or white rice .
It also helps us appreciate that when you control for protein, fiber, and calories, body fat loss is statistically the same between Low Carb vs. High Carb [3, 4].
Intermittent Fasting vs. Small Frequent Meals [5-7].
It also helps us see why utilizing pre-portioned meals has beat dietary advice for fat loss in every single head-to-head study to date [8-13]!
My Fit Foods makes it SO MUCH EASIER to actually get into a caloric deficit where our bodies are forced to burn stored fat for energy.
I hope this stroll through a bit of biochemistry helps you understand where the fat is going and how we at My Fit Foods can accelerate your results while saving you time and money!
