Diet Recommendations
A healthy diet is essential for brain functioning.
Many kids have the false idea that a low-fat diet is healthy for weight control. Fat is a major component of a healthy diet and is essential to keep our brains and many other organs running properly. Your brain is mostly made of fat, so don't skip out on one of your body's most essential building blocks. Carbohydrates are turned into glucose which is the only fuel that your brain can use for energy. Our neurotransmitters are made from amino-acids which are the breakdown products of protein we eat. Without the right amino-acids, we can make ourselves depressed, anxious and slower thinkers.
A balanced diet of an even proportion of fat, carbohydrates, and protein is probably the best diet for humans. We must also account for activity level when we eat. If you are a couch-potato, the calorie requirements are not the same as if you are an endurance runner.
Some helpful tips
1lb=3500 calories
-if you want to lose a pound or gain a pound, it’s all about the numbers. If you eat 500 calories more than you need, you’ll gain a pound per week (500x7=3500calories=1lb). If you eat less or exercise equivalent to 3500 calories less than your base calorie need, you will lose one pound.
Base calorie need:
-take your weight in lbs and multiply by 12 and that’s the minimum number of calories you need to stay your current weight. If you do lots of physical activity, you may need to multiply by 13 or 14 to get you basic needs. If you need to lose weight, then multiply your target weight by 12 and eat that many calories.
Food Diaries:
-keeping a food diary and using web resources to calculate you total calorie intake, fat/protein/carb balance is really helpful. “Lose It” is a great application if you have an iPhone. Caloriecount.com and livestrong.com are other great resources.

Life is not a Spectator Sport- by George Sheehan MD
The weakest among us can become some kind of athlete, but only the strongest can survive as spectators. Only the hardiest can withstand the perils of inertia, inactivity, and immobility. Only the most resilient can cope with the squandering of time, the deterioration in fitness, the loss of creativity, the frustration of emotions, and the dulling of moral sense that can afflict the dedicated spectator.
Physiologists have suggested that only those who can pass the most rigorous physical examination can safely follow the sedentary life. Man was not made to remain at rest. Inactivity is completely unnatural to the body. And what follows is a breakdown of the body's equilibrium.
When the beneficial effects of activity on the heart and circulation and indeed on all the body's systems are absent, everything measurable begins to go awry.
Up goes the girth of the waist and the body weight. Up goes blood pressure and heart rate. Up goes cholesterol and triglycerides. Up goes everything you would like to go down and down everything you would like to go up. Down goes vital capacity and oxygen consumption. Down goes flexibility and efficiency, stamina and strength. Fitness fast becomes a memory.
The seated spectator is not a thinker, he is a knower. Unlike the athlete who is still seeking his own experience, who leaves himself open to truth, the spectator has closed the ring. His thinking has become rigid knowing. He has enclosed himself in bias and partisanship and prejudice. He has ceased to grow.
And it is growth he needs most to handle the emotions thrust upon him, emotions he cannot act out in any satisfactory way. He is , you see, an incurable distance from the athlete and participation in the effort is the athlete's release, the athlete's catharsis. He is watching people who have everything he wants and cannot get. They are having all the fun: the fun of playing, the fun of winning, even the fun of losing. They are having the physical exhaustion which is the quickest way to fraternity and equality, the exhaustion which permits you to be not only a good winner but a good loser.
Because the spectator cannot experience what the athlete is experiencing, the fan is seldom a good loser. The emphasis on winning is therefore much more of a problem for the spectator than the athlete. The losing fan, filled with emotions which have no healthy outlet, is likely to take it out on his neighbor, the nearest inanimate object, the umpires, the stadium or the game itself. It is easier to dry out a drunk, take someone off hard drugs or watch a three-pack-a-day smoker go cold turkey than live with a fan during a long losing streak.
Should a spectator pass all these physical and mental and emotional tests, he still has another supreme challenge to his integrity. He is part of a crowd, part of a mob. He is with those the coach in The Games called, "The nothingmen, those oafs in the stands filling their bellies." And when someone is in a crowd, out go his individual standards of conduct and morality. He acts in concert with his fellow spectators and descends two or three rungs on the evolutionary ladder. He slips backward down the development tree.
From the moment you become a spectator, everything is downhill.
