Six months later, and change.
I have finished my first semester of medical school. I have dissected a human body. I have memorized the citric acid cycle.
After one semester of medical school, here is my first bit of advice: Starve yourself. Disregard if you have been diagnosed with anorexia or bulemia, but honestly, the anorexics and bulemics are going to have to bite the bullet for the tens of millions of obese Americans. Sorry, majority rules.
America, you are loaded with useless extraneous tissue.
Long ago I posted a link to the layers of a human. Now that I have personally dug through those layers, allow me to recap.
On top you got your skin. It's pretty thick. You'd be surprised.
Under that there is some pinkish, sorta creamy, sorta fibrous stringy stuff, with all of your fat in it. Then under that there is a tough, definitely fibrous layer. And under that fibrous layer there are your muscles. If you're in the belly and you keep going there's another layer before your actual 'guts' (if you will), but enough about that.
Point is, under your skin and above your muscles is where your fat is, and IT ISN'T YOU. Your muscles are organs and stuff are the useful part of your body. That fatty, yellow, creamy stuff is not you. It's junk. Get rid of it. Starve it off. Starve yourself and tell yourself it's over. I won't do it to myself.
Because it isn't you. It's a parasite. And frankly, it's gross. So starve it off.
P.S. Dudes, I am talking 1800 calories. Ladies, you can probably do 1500, unless you're buff. Of course it matters what you eat. Ever hear of a glycemic index? If you haven't, read about it. Eat stuff with a low glycemic index. Examples: Beans, citrus fruit, pumpernickel bread, apples, spaghetti (al dente), lentils, barley. BAD examples: Potatoes, ice cream, white rice. You need calcium for your bones. Make sure you're getting enough. If you're a vegan or something take a supplement, but don't overdo it, you'll get the stone. You don't really need more than 100 grams of protein a day, so take it easy, don't go nuts eating fifty chicken breasts. You do need meat for the vitamin B12, but take it easy. Maybe 5-8 ounces of lean meat per day in addition to your tons of vegetables fibrous grains. When you want a treat have some fruit.
About exercise: Do it. The more of it you do, the more bad stuff you can eat. If you aren't willing to bust your ass for an hour a day, nothing high glycemic index for you. If you run a lot or lift lots of weights, then go ahead and eat a potato, it will actually be good for you in that case.
Your body was made to get its ass busted, i.e., running, climbing, breaking things, raging. If you don't do this type of stuff, you need to watch your diet like a freaking hawk, and you need to starve yourself. But if you start living like an animal, if you can make yourself (with apologies to Full Metal Jacket) born-again hard, then you can eat high glycemic. Otherwise it's barley for you, buddy. Hands off the fries.
Bottom line: Choose your attitude.
"I'm soft and I'm not willing to bust my ass for at least an hour a day."
Prescription: 1800 for a dude, low glycemic, rest of your life, no exceptions, no days off.
"I'm born-again hard."
Prescription: 1800 to much much higher, depending on how hard you bust your ass (find some calorie tables, see how many calories various forms of ass busting use up), and some high glycemic, especially around or during ass-busting times.
Period, it's over, done. No mysteries. Science knows the truth and it ain't pretty.
