I didn't know that thank you I shall start weighing the protein as well
The guidelines for protein vary a lot depending on age, sex, activity levels etc. The 1g per kg weight is a one size fits all and is the minimum amount we should consume, not necessarily the ideal amount. You need what you need. It is an essential component of every cell in the body. Hair and nails are made of protein. It builds and repairs tissue. It makes enzymes, hormones and such like. It is an important macronutrient for bones, muscles, cartilage, skin and blood. Unlike fats and carbs, protein is not stored (as protein) by the body, so needs constant supplies. Too little and we suffer.
Some of the excess protein can be broken down and stored in the liver where it is converted to glucose to be used mostly in the absence of carbs or when the body detects too little glucose in the system for its immediate needs, such as during times of exercise or fasting. This is how we get liver dumps.
It is all a fine balancing act.
