What happens to the body when you stop eating carbohydrates?

Carbohydrates, or carbs, are one of the three major macronutrients that fuel the human body, the other two being proteins and fats. In simple terms, carbs are the body’s most accessible source of energy. They are found not just in staples like rice, chapatis, and potatoes, but also in fruits, vegetables, milk, pulses and whole grains.
Biologically, carbs come in three forms:
• Sugars – The simplest, quickly digested form found in fruits, milk, sweets, etc.
• Starches – Longer chains of glucose found in cereals, rotis, rice, pasta, potatoes and lentils.
• Fiber – The indigestible component found in vegetables, fruits, whole grains and seeds that feeds the gut, stabilises blood sugar and supports digestion.
