Epicurians will say we should enjoy life and eat as much as possible in our life time. The Stoics on the other hand will say that we should live a frugal life, eat as little as possible to survive and be immune to pleasure , pain and suffering.
There are others who say that we should LIVE TO EAT and yet others will tell us that we should EAT TO LIVE.
From the net I got the following information.
People today eat way more than they used to — and way more than they need to. This means that they're constantly taking in more calories than their bodies can burn. Unfortunately, lots of us don't realize that we're eating too much because we've become so used to seeing (and eating!) large portions.
Portion sizes began to increase in the 1980s and have been ballooning ever since. Take bagels, for example: 20 years ago, the average bagel had a 3-inch diameter and 140 calories. Today, bagels often have a 6-inch diameter and 350 calories. One bagel that size actually contains half a person's recommended number of grain servings for an entire day!
The price of such overabundance is high. It's common knowledge that people who consistently overeat are likely to become overweight. But they also risk getting a number of medical problems, including high blood pressure, high cholesterol, type 2 diabetes, bone and joint problems, breathing and sleeping problems, and even depression. Later in life, people who overeat are at greater risk for heart disease, heart failure, and stroke.
It's easy to understand why the food industry tends to serve way more food than is necessary: Customers love to feel like they're getting the best value for their money! But the value meal is no deal when it triples our calories and sets the stage for health problems.
I generally eat very moderately. But after some days of moderate eating the temptation to eat a full stomach overcomes me. On one such day, I was walking on MG Road and saw a menu board on the sidewalk in front of a restaurant with the word KABSA. I was curious. I went in and asked the man at the counter about the word KABSA. He explained to me that it is a delicious biriyani eaten by the people of Arabia. I couldn’t control myself. So I ordered a plate of chicken kabsa and ate a stomach full. I felt sick due to over eating, tired and sleepy too. With great difficulty I got up, paid the bill and went to Lourdes Hospital to meet a friend who was admitted there for heart ailment.
Since I was feeling sick due to over eating, I went to the cafeteria in the hospital, bought a cup of coffee and sat at one of the round tables and started sipping the coffee. My attention was caught by a slim middle aged woman who briskly walked towards my table and sat on a chair. She looked at me but I pretended to look the other way. She quickly took out a stainless steel container and a small plastic container. She opened them and I saw the stainless steel container had plain boiled rice and the small plastic container had some vegetable curry. Once again she looked at me but I pretended not to notice her. She then took a pinch of vegetable curry and put it on top of the rice and ate it. Then she ate three or four handful of plain rice. Since the plain rice was not going down her throat she pulled out a plastic bottle with water from her bag and gulped down some water. Again she took little vegetable curry and ate it with the rice. Then she repeated the procedure of eating three or four handful of plain rice and gulp down some water. In this way she finished eating the entire rice. Then she got up, took the containers to the nearby tap, washed them, put them back in her bag.and walked away. May be she didn’t have enough money to buy a decent meal, I thought. But she looked very strong and healthy whereas I was sitting there feeling sick, tired and sleepy on account of over eating.
I am sure you have your own views on the subject. Best wishes.
