- During fasting, fatty acids are an important source of energy for liver and other tissues. If they are not converted to energy, it results in lethargy (lack of energy) and hypoglycemia (low blood sugar).
- Energy from fat keeps us going whenever our bodies run low of our main source of energy (glucose.) This might happen if we miss a meal or when we sleep.
- Once sugar or glucose is gone, the body tries to use fat without success. This leads to low blood sugar (known as hypoglycemia) and the buildup of harmful substances in the blood.
