Energy-boosting foods are also metabolism-boosting foods: foods that support our bodies' abilities to convert food into energy. “Alas, our bodies are not 100 % efficient at converting food energy into mechanical output. I advise all my one on one coaching clients to incorporate a 12 hour overnight fast, for example, finish eating at 8 pm and start eating at 8 am. This question sort of comes to mind when hearing how efficient an internal combustion engine is turning chemical energy in mechanical energy (something like 20-40%) with lots of excess heat. (5) The body converts the chemical energy of food to the chemical energy of ATP with about 50 percent efficiency, converting the rest to fat. B-complex vitamins and omega-3 fatty acids are some of the most energy-boosting nutrients available, but many other nutrients and flavors are associated with increased wakefulness and alertness. When your body does not have enough iron, your cells do not receive enough oxygen and cannot produce enough energy. So TSH is within normal range because the pituitary is getting plenty of thyroid hormone, but the rest of the body is hurtin’ for certain.
