Feasting and Fasting phases

1. Our body's insulin level increases when we eat and slowly goes down. When it hits lower limit our body asks for more. If we have enough stored fat and we don't eat body start burning fat. If there is not enough fat body will convert protein to glucose and burn it increasing insulin level for short time. Phases of eating is feasting and phases of not eating is fasting.
2. Our body need to switch between these phases and rise of insulin level should be momentary.
3. Food high in fiber can increase insulin level for longer duration. This may lead to insulin resistance. Food high in fiber can also cause Irritable Bowel Syndrome.
4. Fat burning leads to ketosis (It generates ketones) which is good for functioning of mitochondria in each cell. It is also very healthy for heart and brain.
4. Eating once or twice a day (not even having even very small meal in between) and water only fast once in a week is good way to keep fit.
