I had been on a “no-rice” once in a while. It is my means of losing weight especially when I wold hear someone’s remark that I am getting bigger. But I have noticed that when I had no rice for the day, I would feel sluggish on the next day and particularly after lunch time, my eyes would be drooping as if I lacked sleep even if my sleep was enough. What can you say about rice or any other food that supply us with carbohydrate for energy, not having those food will make us weak?
This is part of the transition from burning carbs (sugar) as fuel to burning fat as fuel. If you think of sugar as small pieces of kindling wood that you can put on the fire, and fat as the large log that burns all night, this might help you understand better,
@Corzhens .
When you are burning small pieces of wood, it can burn very hot, but you have to keep putting more pieces of kindling on the fire to keep it going, and that is similar to how our body burns sugars. We only store a small amount (compared to fat storage), and so every few hours, we need more fuel, or you are tired and hungry.
When you transition to burning fat ketones for fuel, it is like throwing that big chunk of wood on the fire, and it will burn all night long. We have enough fat on our body to last many days, even when we are not carrying excess fat; so once you get past that burnout of sugar, and start burning fat, then you will have plenty of energy.
Since you have a huge supply of steady fuel, you really do not get hunger pangs either, because your body is not running out of fuel.
