Fasting has many flavours in India.
There is a water fast. The fruit fast. The sabudana fast contains more calories than a wedding buffet. The “only liquids” fast includes three glasses of sweet lassi. The intermittent fast begins at noon and quietly ends at 11 pm. And my personal favourite — eating everything except rice and calling it fasting. We are a civilisation that can convert any dietary restriction into a festival menu.
This morning, my son announced, “I fast every day.”
I asked him when.
“At night,” he said. “It’s called sleeping.”
He laughed. I laughed. Then I realised he had accidentally summarised human evolution. For thousands of years, humans stopped eating when the sun went down. Darkness meant pause. No philosophy. No app. No metabolic debate. Just rhythm.
Then electricity arrived. Refrigerators arrived. Food delivery arrived. Hunger became optional. Now we panic if lunch is delayed by thirty minutes. Our grandparents survived drought.
In my clinic, fasting enters like a theatre.
“Doctor, today I am fasting,” a gentleman declares proudly. By evening, his glucometer shows numbers that suggest a festival inside his bloodstream. Sabudana, peanuts, fried potatoes, and sweet tea. He removed rice. He kept everything else. The pancreas does not understand symbolism.
On the same day, an elderly woman sits quietly in my clinic. She drinks warm water throughout the day. Eats lightly at sunset. Speaks softly. “Body feels less heavy,” she says. Her sugars remain stable. Her sleep improves. She does not post about it. She practices it.
Both are fasting.
Only one is resting. We fear hunger more than we fear excess.
In Indian homes, food equals affection. Refuse food, and someone feels insulted. A fasting person becomes a topic of family discussion. “At least eat fruit.” “At least drink milk.” Hunger disturbs the emotional ecosystem before it disturbs the stomach. But the body understands cycles.
When we stop eating, insulin falls. The liver releases stored glucose. After some hours, the body shifts to a different fuel. It begins to burn what it has saved. Quietly. Efficiently. No drama.
Cells begin maintenance. Damaged proteins get cleared. Old components get recycled. Scientists later named this process and awarded prizes for discovering it. Biology had been doing it long before laboratories confirmed it.
Ayurveda described the same rhythm through the concept of agni. Feed the digestive fire constantly, and it labours without pause. Allow it rest, and it reorganises. Upavasa did not mean punishment. It meant discipline. Sitting near awareness.
Hunger reveals temperament.
The first wave arrives loudly. The second wave weakens. Wait long enough, and it passes. Cravings behave like thoughts. They demand attention. Then they dissolve. Most of us have never observed a craving without negotiating with it.
Watch what happens on a well-structured fasted morning. The mind feels clearer. Not spiritual. Clearer. Digestion consumes blood flow and energy. When it rests, attention sharpens. People call it lightness. It is physiology.
But fasting is a stimulus.
Push it gently, and the body adapts. Push it aggressively, and the body resists.
A young woman extended her fasting window after reading enthusiastic online advice. She came to me exhausted. Irregular cycles. Hair thinning. Irritability. She thought she was cleansing. Her body entered conservation mode. Biology distrusts extremes.
An elderly diabetic on insulin cannot experiment casually. A pregnant woman cannot treat fasting as a fashion. Context decides benefit.
I once had a man who lost twelve kilos through structured intermittent fasting. He felt triumphant. Six months later, the weight returned. Stress remained constant. He removed food. He did not remove anxiety. Cortisol continued its quiet work. The body stores when it feels unsafe.
We live in a convenience culture. Food arrives faster than thought. Kitchens operate all day. Screens glow all night. We solved scarcity. We forgot rhythm.
Fasting unsettles convenience.
It forces waiting. It exposes a habit. Many people do not eat because they are hungry. They eat because the clock says so. Or because someone else is eating. Or because the mouth feels bored.
Across cultures, humans ritualised hunger. Different prayers. Same metabolic rehearsal. Shared fasting synchronised communities long before anyone measured insulin.
What disturbs modern people is not hunger. It is an empty hour. We fill them instantly. With snacks. With scrolling. With noise.
My son’s joke returns to me.
“If sleeping counts as fasting,” I told him, “then opening the fridge at midnight cancels the whole thing.”
He laughed. But the point remained.
Night still offers a natural fasting window. We shorten it. We snack into it. Then we experiment with artificial fasting and treat it like an innovation.
The question is simple. Can we create a structured absence without panic?
In Bengaluru, I see more people fasting for weight loss than for reflection. Motive varies. Biology does not examine motive. It responds to a pattern.
Skip dinner occasionally, and many people sleep better. Stop constant grazing, and the pancreas breathes easier. Create rhythm, and the body responds with surprising cooperation.
Fasting is not about food. It is about control. Hunger passes. Habit does not.
I have written a book.
If this blog spoke to you, the book will stay with you longer.
