The Nutrients which mainly give energy to our Body before we dig in the discussion about nutrients for the human body, let us first understand what fuel is. In simple language, it means that it is an agent by which energy is transferred from a place to another and that it is used by the body to maintain its existence. This energy is used in the form of ATP in the human body. The human body derives its ATP or its energy from different nutrients during different states.
The different States of Human Body
So before we can talk about the Nutrients which mainly give energy to our Body, we must also know about the other human body conditions.

The fed state of Human Body
The fed state of human body is defined as the duration of 8 hours since last meal. It is the time duration just after we eat any food or drink any beverage full of calories.
The fasting state of Human Body
Beyond 8 hours since last meal is known as the fasting state of human body. Our nature has got its tricks to gift our body a daily fasting state session. Remember the time you go to bed? Those eight happy and relaxing sleeping hours are the human body’s natural fasting state hours
The Starvation state of Human Body
while beyond 24 to 36 hours since the previous meal is the duration of starvation. Our body has unique mechanisms to counter starvation, but remember keeping your body starved leads to your physical and mental health deterioration.
What are the rich sources of the Nutrients which mainly give energy to our Body.

- Fruits (Carbohydrates, Vitamin C, A and other major anti-oxidants)
- Vegetables (Vitamin C and A)
- Grains (Carbohydrates, Vitamin B and Fibre)
- Pulses (Proteins, Essential Amino Acids, Carbohydrates)
- Egg Yolks (Vitamins A, D and E)
- Milk (Calcium, Magnesium, Lactose, Casein, and all the major nutrients)
- Soya Bean (Vitamin K)
- Red meat (Iron and Zinc)
- Seafood (Good sources of Iodine and omega fatty acids)
Sources for blood glucose during different states
Predominantly during the fed states, Carbohydrates in food acts as the primary nutrient to fuel our body. So mostly our meals serve as a chief source of blood glucose. Usually, our average meals gift us 75 grams of glucose and other nutrients like proteins, fats, vitamins, minerals, etc., out of which 75 grams of glucose forms the basis for our blood sugar testing. If we talk about blood glucose sources in fasting states, it is predominantly our liver glycogen, that is the duration if you are talking about 12 to 8 hours since the last meal. Beyond that, it is chiefly the body proteins, with the help of Gluconeogenesis.
What is Gluconeogenesis and is it harmful?
Gluconeogenesis is a high energy-requiring process, and the preferred primary nutrients fueling our body during that time are proteins and fats.So, Gluconeogenesis is not harmful, it is actually a normal physiological body process.
In short, we can say that carbohydrates are the chief fuel for a body during the Fed States while the fats are the dominant fuel for a body during the fasting states and the proteins are the chief Nutrients which mainly give energy to our Body during the Starving States.
Why must we know about the Nutrients which mainly give energy to our Body and different Body States?
The answer is simple, Weight loss and a healthy lifestyle. So for those who are curious about learning the techniques to reduce the weight, the morning walks are highly efficient in reducing the weight since the fats are utilised during the morning, as the night period of 8 hours in which we sleep acts as the chief fasting duration for a human body after which body starts to use fats have the facts breakdown is maximum in the morning before breakfast.
