Why We Eat What We Eat

Why We Eat What We Eat
(In Praise of the Minimalist Diet)

By Basil Gala, Ph.D.



(1508 Words)


Why we eat? What kind of a question is that? Why, we eat because we are hungry! Nothing drives us to food with as much alacrity as hunger pangs. Hunger is strongest in childhood when the body most needs nutrition for growth and energy; hunger is an instinctive response of an animal to bodily needs. A classic psychological experiment put infants in front of a large variety of foods (bread, fruits, ice cream, candy, meat, vegetables, cake, cheese, milk), letting them eat what they wanted. At first, the infants went for the candy, cake, and ice cream, but later they chose to eat what a nutritionist would have prescribed for their bodily needs. Infants behave naturally to boost health, just like other animals; yet, as you grow older enmeshed in culture, hunger cannot be your sole guide to eating right; you could end up fat, with diabetes, arthritis, and heart disease.

Besides hunger, other reasons why we eat may also lead us to gain ungainly weight instead of good health: eating for pleasure, for a birthday or other celebration for feasting; eating because it's time to eat, or because the food is there in front of us on our plate; eating food offered to us by someone we like or love, someone like our mother, wife, friend, or a movie star, cleaning our plate and the plates of our children so the food doesn't go to waste; eating while watching television or a movie to relieve our tension from the drama; eating to relax from the stresses of work, family, or social connections. The reasons for eating are endless, but none of them is sufficient by itself to fully justify eating, except one.

The only sufficient reason that justifies eating is: to give our body the nutrients it needs for healthful living.

The other reasons why we eat are good too; but hunger, convenience, celebration and so forth should not divert us from the objective of giving our body the very best nutrients in the right amounts; having picked food which satisfies our body's needs, then we may seek pleasure, etc., in what we eat.

Hunger is good; when we go to our meals with a strong appetite, we smell and taste acutely the deliciousness of roasts, baked dishes, and fresh fruits, or vegetables. We eat well, we are satisfied; we digest better. If the food is nutritious, we don't want more, we stop eating when we had enough. Nutritious food is chockfull of proteins, good fats, vitamins, minerals, fiber, anti-oxidants, and phytochemicals, yet low in calories. Good foods satisfy us for several hours; but if we eat sugary snacks, white-flour products, white rice, potatoes, and other denatured, high-glycemic foods, hunger returns soon with a rebound, pushing us to eat more of the same junk. Thus we take on more fat, while our body starves.

True, the body's primary need is for energy, glucose released slowly in the blood stream from good foods, to operate the brain and other organs, especially our muscles; about 70% of the calories we take in are used that way, even without exercise. Adults need surprisingly small amounts of protein for tissue repair and fat for vitamin transport: daily about 70 grams of protein (unless you are building muscle exercising hard), and 35 grams of fats: that's three ounces of protein and two tablespoons of oil, from all food sources. Any more protein or fat we may eat is burned for energy, excreted, or converted to body fat. Burning protein or fat produces toxic ketones; with water as byproduct, burning complex carbohydrates for energy is healthier, provided we eat whole grains, fruits, and vegetables.

Having regular meals is fine too; it's a good discipline. Body and mind get ready for food at a habitual time, assisting digestion, elimination, and energy production when needed. My dad always ate at 7 am, 1 pm, and 7 pm--if he could help it. He never admitted to being hungry, considering that a weakness. His breakfast was oats and milk, lunch a cooked protein meal, usually fresh fish, and dinner, a salad; he lived to a hundred years. Start your day, then, with a rib-sticking whole-grain breakfast, and end your meals with a light dinner, early. If you eat too close to bedtime, you will convert more food to fat, because you will not use your muscles much during sleep.

Celebrating life with food in the company of family and friends is also pleasing and beneficial. A little wine helps lift our mood, as well as satisfy the palate. We should not eat in the presence of people who upset us. I never complain about the food or service in a restaurant; I just go elsewhere for a meal. It is better for our health to skip a meal than eat one in a sour, unhappy, frame of mind.

There is nothing intrinsically wrong with convenience or economy in food preparation, if the nutrients, quality, and quantity are also there in our servings. Our problem is often in the quantity of food we consume.

People in rich countries eat too much, unless they are models or desperately want to look like movie stars. Studies with animals and humans show that a low-calorie diet promotes good health and extends the life span 30-80% through the activation of the SIRT-1 gene, nature's way to get animals get past food scarcities; a diet of 1200-1500 calories a day for the average adult, but containing all necessary nutrients. Ah, there's the rub! If you want the benefits of a calorie-restricted diet, you have to be very careful about what you eat. Some people follow the rule of eating a little bit of everything, including sugary and fatty foods. Well, this rule is okay as long as you are very active, eating enough to get the necessary nutrients and using the extra calories for energy. For the rest of humanity, a misstep in downing a drink, a sweet, or a piece of meat could derail a healthy regimen. It is vital that for all your meals you choose food high in nutrients but low in calories.

High-nutrient content with low calories are found mostly in low-starch, low-fat vegetables; breast of chicken or turkey, fresh fish, egg whites, non-fat dairy (cottage cheese, yogurt, milk), are fine in small amounts, but have no fiber, a very important nutrient for good digestion and hunger control. I prefer whole grain and bean products as sources of protein for good health, including tofu and other soy milk products, eggplant, dark green leafy plants, and mushrooms. Get your antioxidants and phytochemicals from tomatoes, carrots, peppers, berries, and fresh fruits. If you slip up and eat something like French fries or onion rings, marbled meat, pastry, ice cream, whole cheese, you will likely end up with two problems: you'll take in more calories than you are able to use for energy, turning those extra calories to fat; or skimp on your next meal or two, depriving your body of essential nutrients.

When planning, preparing, ordering, and eating meals, first think of needed nutrients. Still since infancy, you and I have developed certain preferences in food. We have our habits for over eating and wrong eating. We have grown up in a family with its own peculiar eating culture; we have matured in a particular ethnic cuisine, American, African, Asian, or European. Inevitably, unless we consciously intervene, we continue behaving according to personal and social habits, even though this way we damage our health.

Consciously intervene in the process of eating; exercise mindfulness (concentration) before eating and during eating; after eating allow some time for the food to leave your stomach, then seek means to exercise. Plan your meals to make them right for you and your family. Use small plates; serve small portions of protein, carbohydrates, veggie fiber, and fats; avoid buffets. Take small spoonfuls and forkfuls of food, chew well, and enjoy the flavor and aroma of each bite. Set your fork or spoon down while chewing. Count calories or portions consumed each day to stick to the longevity diet, because you want to thrive and prosper.

Remember again, to exercise before and after meals regularly. Exercise depresses hunger, while burning calories. If you have reached your calorie limit for the day, drink something with fiber such as psyllium husks, exercise, get busy with something to get your mind of food, or go to sleep. If you can keep your mind off food, sleep depresses hunger. Try prayer or meditation at bedtime. Next morning you'll have a lovely appetite for a hearty, nutritious, and delicious breakfast.

Why you eat what you eat is dictated by your background; don't take dictation which harms you, whatever its source: personal habits, family, ethnicity, or religion. It is all right to discriminate against what's destructive to your life. Be your own person, directing your actions after conscious thought to a better life with vigorous body, mind, and spirit.

The Magic of Light Eating

The Magic of Light Eating

By Basil Gala, Ph.D.


Do you remember when you were a kid and had to share a piece of pie or cake with a brother or sister? You each looked carefully to the cutting of the sweet to make sure you were not short changed. In a world which in the past was short of food, getting a fair share of it, or more, became instinctive. Whoever ate more was more likely to survive the next famine. Today, in wealthy societies, we have the opposite situation. We have a superabundance of food which has brought us an epidemic of obesity. You will live a longer, peppier, and healthier life with less food: less food means more life; light eating is magical indeed.

Biologists have known for many decades that animals have longer and healthier life spans when the calories they consume are restricted. Recently, we have found some evidence from genetics to explain how this happens. A period of light eating activates (triggers) a gene, SIRT1, which performs the magic when scientists deprive laboratory animals from eating all the food they normally eat from what is laid out for them. The procedure is called calorie restriction (CR) or calorie deprivation (CD) in biology. I call it calorie control (CC), light eating for you and me and our families.

You may ask, what about nutrition? In the experiments, biologists supply the full nutritional needs of the animals. But they found out that they can still reduce calories by 30%. Initially the animals lose weight, but after a time, weight loss stops, and the animals remain lean, vigorous, and very healthy, to a very advanced age. Mice, and all other species of animals to which the procedure is applied, maintain a normal weight when allowed to eat as much as they want, as opposed to humans who often overeat compulsively, getting fat. Once well fed, animals tend to other needs, such as reproduction.

Reproduction takes precedence over longevity when the food supply is plentiful. When food is in short supply, that’s when the SIRT1 gets to work: animals do better when they live longer to get past the scarcity to the next plenty for their offspring to eat. Then again, the SIRT1 gene is de-activated during times of plenty.

In the case of mice or rats with diabetes induced by experimenters, the disease is reversed with caloric restriction. The gene for diabetes is de-activated, after SIRT1 has been activated.

Incidentally, resveratrol, a polyphenol in red grapes and other plants, brings some of the benefits to health of SIRT1 activation. Plants produce this phytoalexin to counter infections from bacteria and fungi. Associated with the French paradox of health, resveratrol fights cancer, viruses, inflammation, and extends life, if taken in large quantities. A small company in Massachusetts, Sirtris Pharmaceuticals, is working to synthesize a compound stronger by far than resveratrol to bring us these benefits without calorie restriction. This medicine is in the early stages of development and may not pan out. In the meantime, we have the option of light eating.

What can we make of this magic of light eating in our lives as humans? We don’t know that we can extend our lives with SIRT1 activation, because experiments with humans are in the initial stages. A pioneer in CR, Dr. Ray L. Walford of UCLA, applied the procedure to himself with the objective of living to 120, but he did not live much beyond a normal human life span, dying two months short of 80. We have, however, much evidence that CR promotes healthier, longer, and more vigorous lives in us humans--provided we get the nutrients we need for growth, tissue repair, and energy.

Specifically, if you maintain a normal weight with 2,000 calories a day, using light eating you cut the calories down to 1,400. You will lose weight and fat for a while. Normal weight according to the charts is probably not the healthiest. Normal is average, and the average weight in the U.S. is too high. Check your body fat percentage: that should be about 15% if you are a man or about 17% if you are a woman. If you continue to lose fat getting much below 15% or 17%, increase your calories to maintain the right body fat percentage for you.

Mind, I am not advising here a strict diet to drop 20 or 60 pounds, look and feel great for a while, then resume your customary eating, regaining the weight just as quickly. The longevity gene is activated to render its health benefits to you after you have restricted calories for a long time. The gene will quickly get de-activated with a little overeating. To benefit fully from the magic of light eating, you commit to it for the balance of your life, every day. To do this, you look at food, not as a source of pleasure so much, but as a source of healthful nutrients. It has been said: “Eat to live, don’t live to eat.” I say, “Get your nutrients first, please your palate second.” Yes, you want to enjoy thoroughly what you choose to eat for health. Thus you avoid feelings of deprivation which lead to eating fattening foods. When you enjoy delicious food leisurely, you digest it better too.

But how do you get enough nutrition from 1,400 calories a day? Ah, there’s the rub: you must eat foods high in nutrition and low in calories. Pack your 1,400 calories with good stuff only. Don’t eat refined grain flours in pasta, breads, or other products; eliminate sugary snacks, fats such as butter, shortening, nuts, avocados, white rice and potatoes, or just have an insignificant amount of such foods for taste. On the positive side, after maturity humans require very little in nutrients. Protein is very important, but 3-4 ounces of protein a day from all sources is sufficient for tissue repair. You need some good fat, unsaturated or mono-saturated with omega-3s and omega-6s, but only two or three tablespoons of fat a day. So far you have used up about 600 calories. The rest can be complex carbohydrates from vegetables and fruits, giving you fiber, vitamins, minerals, and phytochemicals with antioxidants. You can also take non-caloric supplements for any other nutrients your doctor recommends.

You may object: “But I would be very hungry with 1,400 calories only.” I say to you, it’s okay. Get good and hungry for your next meal; you will enjoy it more. Your best chance of a great meal next time is to limit your present meal. Hunger will enhance your smell and taste. Choose to eat the most exquisite foods in small amounts. You can afford these foods since you will eat so little. Relish every precious morsel of delicious food, eating slowly. Lay your fork or spoon down for a minute between bites and chew well until each savory morsel flows down your throat. We are not wolves to be bolting down our food. Most people don’t pay enough attention to their food. Concentrate, meditate, with full awareness on what you are eating; try not to think about anything except your food. Certainly don’t walk television, or read while eating. Don’t talk until after you have swallowed; that’s also polite. Music can also be distracting, although you may listen to fine music to relax before the meal or afterwards. When you are no longer hungry, stop eating and begin digesting your small meal. I repeat: this is the way to prepare for the best enjoyment of your next meal, by having fully digested what you ate before, by getting quite hungry again.

When hungry we tend to eat faster; get used to slowing down instead, allowing twenty minutes to elapse until your blood sugar has moved up and hunger subsides. Have you noticed how quickly people eat in our busy society? Fast food is not only served fast to us; we tend to eat it fast also. Put a platter of food on the table with several people to share. Notice how quickly it disappears. That’s instinctive in us. We want our share before someone else takes it. Let others serve themselves and take a little of what’s left. You will not starve, I assure you.

Before you eat something, estimate the calories on your plate and get a subtotal for the day. You have a budget of 1,400 calories, which you must not exceed. Does that seem hard to do? At first estimating calories is a daunting task, yes, but you will get used to a quick estimate in each portion of food with constant practice. Initially, a food scale, recipe cups, and calorie reference book will help. I recommend The Calorie King Fat and Carbohydrate Counter. If you are having difficulty keeping track of calories, eat prepared meals until you get used to portion sizes of the right foods. Eating off an 8-inch plate with a small fork or spoon will also help.

To limit calories each day, try meal replacement for dinner with a protein-juice-psyllium drink or a commercial product; if you are dining out replace your lunch with a protein drink.

If you find you get too hungry between meals on light eating, and are tempted to gobble up something like a small candy bar (240 calories) or a doughnut (350 calories), then snack on something low in calories and high in fiber. A snack on a carrot, cucumber, celery, jicama, lettuce, broccoli, cauliflower, or other raw vegetable will serve you well. A protein drink with psyllium fiber or oat bran also works wonders in suppressing excessive hunger. Four or five nuts, if you can limit yourself to that many will cut down between-meal hunger too. Eventually you will get used to light meals. As my sister likes to say, your stomach gets smaller. Or, your eye gets smaller than your stomach.

People in wealthy nations have big stomachs, eating far too much, overindulging in their appetite for a huge variety of high-calorie foods, especially animal products. Most of the food goes to waste, not even turning into fertilizer like the Chinese “night soil.” Our bodies are constantly burdened with digesting too much, making us sluggish and sleepy and we constantly slosh down caffeine drinks to stay awake at work or play. You will be far more alert and energetic on light eating, without stimulants.

With light eating, you will experience the magic of weight loss without diets, pills, or liposuction. To lose and maintain the right weight, keep in mind that about three quarters of the calories we take in are burned up just to maintain body functions; exercise uses the balance of the calories that we put to good use. (Walking all day just drinking water will burn one pound of body fat.) The rest of your food is excreted or stashed into fat tissues for the next famine.

If you don’t expect a famine next winter, but want to get rid of excess fat, light eating is the answer for you--with the aid of some daily exercise. Don’t expect too much from exercise, because you need to burn about 3,500 calories to get rid of one pound of body fat. Walking uses about 300 calories an hour. Wrestling, running, or vigorous sex is more effective at 600 calories an hour--50 calories in 5 minutes. But how many of us have the time or stamina to exercise for hours every day? Of course, you can bulk up lifting weights for several hours a day; bulging muscles will burn more calories while you are exercising, or at rest, even asleep. Can you spare the time and motivation for such exertions?

Alternately, you may want to try fasting one day each week. Fasting works magic in many ways as part of a light eating habit. In addition to fat loss, fasting promotes the elimination of toxins throughout your body and gives your digestive system some rest. Don’t fast then gorge; that’s worse than not fasting at all. It’s as bad as skipping meals, especially breakfast or lunch, which some people practice. Gorging then fasting is bad too—similar to gorging then throwing up. I know many people who fast for good health with no ill effects. I usually fast on Sunday, breaking the fast with psyllium, protein power, and juice blended in spring water whenever I get hungry or thirsty. I don’t work on Sunday, taking time to meditate and relax, exercising lightly with yoga. On Monday, I take care to get back to light eating again, not overindulging in food because I fasted.

On light eating, you will find you are less hungry between meals if you eat highly nutritious foods: sprouts, mushrooms, egg whites, chicken breast, fish, and fresh low-starch vegetables, low-calorie high-fiber spinach, kale, broccoli, cauliflower, mustard greens, collard greens, beet greens--are all great for light eating, delicious with some lemon juice, olive oil, a little sea salt. Steaming or quick poaching preserves the colors, flavors, and nutrients of vegetables; it’s my favorite cooking method, if I cook my vegetables at all.

Raw foods are good for you, organic and thoroughly cleaned, but skins on. Eat organic fruits and vegetables with skins, cores, and seeds, if they are very fresh. The best way to get them really fresh is off a tree or vine, ripened to perfection. For such you need a garden; otherwise, go to a farmers market, or select the best, freshest stuff you can spot at the supermarket, usually buried underneath all the stale things, as my mother taught me.

Shopping for food brings me to the matter of savings. You are going to save a ton of money at the grocery store when you are on light eating. Vegetables, grains, and legumes cost far less as a rule than meats and processed foods, especially the small quantities you will be buying. With light eating, you will discover most restaurants serve awfully bad stuff for you and you will eat at home, saving even more money. If money is not a problem for you, think of the food saved for the poor that you will not be putting in your body as ugly, unhealthy fat.

The poor may not be a concern for you, but animals and other living things may be. Light eating implies consumption of fewer animal products, which are high in calories compared to vegetables. Vegetables are living things too; some people believe plants have feelings too, hurting when we cut them down. In our current state of food production we need to cut things down in order to survive, but at least let’s do as little damage as possible with our light eating of leaves, seeds, and fruits.

You may also want to grow your own sprouts for freshness, good quality, and additional savings. I have found sprouts in stores to be of poor quality, often stale, so I grow my own. Fresh sprouts add much to the magic of light eating. They are packed with proteins, vitamins, and minerals, and are low in calories, because fat and carbohydrate content goes down with sprouting. Eat two parts grain sprouts to one part bean sprouts to get complete proteins. You can easily grow sprouts in jars from unprocessed seeds. Rinse seeds daily and drain well. Cover the jar opening with cloth or tissue, so your sprouts are able to breathe. When the seeds have sprouted, put them in your refrigerator, but rinse and drain daily to maintain freshness for up to a week.

With fresh sprouts and other living foods, your body will grow into a lean, dynamic machine very soon. You will be amazed at the energy you will be able to generate. You will love floating on your feet like walking on the moon, never huffing or puffing climbing stairs, gliding up with ease. You will enjoy your curves or angles; so will those that look at you: friends, relatives, and strangers, complimenting you and congratulating you. And what will you have to pay for all this? You will pay less money than before your light eating, enjoying fine dining, exercising only a little self discipline, and rejecting gluttony, one of the seven deadly sins.
