Getting healthy is a mammoth undertaking, no question about it, but it is worth every effort expended on it and then some. The Good News is that you can do it one step at a time. Small simple changes add up in time little by little to produce great results. You didn't get unhealthy over night. It took years of hard work. And it will take about the same time period to reverse all that damage that it took to do it in the first place.
Another consolation is there is absolutely nothing you could better spend you time on than tending to your health. Many things are important but none are more important than you health. Your wife, your husband, your children, your partners, your parents, friends and family, your Country, and your God are all important along with a dozen hundred other things, but you are worthless to all those other people and demands if your health is not tip-top.
Then, after you do this Shape-Up you know you should do, if you do become sick for any reason, you can justifiably make a claim on all those "others" to come to your aid. But, if you have let yourself go in all kinds of ways, and put your health second, then you have a weak case when it come to asking for help from the "others" that you have been an unnecessary burden to.
I want to get this preamble lecture out of the way before launching into what you must do to begin the process of taking care of yourself.
The positives of beginning the process of taking care of yourself has many many rewards. It means you will be a better employee, spouse, father, child, partner, church member, patriot, and servant of God. It means you will like yourself better, have more self-esteem, be happier, make more money, and be more likely to be able to accomplish whatever in life you want to do.
First a couple of basics of good health that may not seem, at first glance, to be part of good health, but believe it they are the essential foundations of good health.
A. Vices you should Dump to take out the trash in your life: These are just some of the common ones. You can add those we may have left out. They are Gambling, Smoking, Drinking, Drugs (both legal and illegal,) Spendthrift Ways, Not Saving, Gluttony, Pride, Arrogance, Envy, Being a Loner, Eating Junk Food, Disloyalty, and Blasphemy, to name only a few.
4. MONEY: The Bible says that "Love" of Money is the root of all evil, and that is true, but notice Money is not called the root of all evil, but rather Loving Money is the root of all evil. The Bible goes on to say that "Money, answereth to all things." and surely it does, so Money itself, properly used, could be called the "root of all good." So Save, Save, Save, MONEY, and if you only make a dollar a day, be sure to save 10 cents of it, and with that rule in place you will have plenty of money all your life. The typical ungodly spendthrift says, "I don't have any money to save." What they mean is "I will never have any money to save, even if I make a million a year." If you can't save when you are broke you will never save when you have more. Saving is a state of mind that has nothing whatsoever to do with how much money anyone has at any one time. Savers save, no matter how little they have, and Spenders spend it all no matter how much they have. Memorize that!
By all means avoid the four killers of the Food Apocalypse: SUGAR, SALT, GREASE, and FLOUR. These four typically have near zero nutritional value, and additionally pack a poisonous punch that you don't want in your system.
Grease, another death ingredient. The Bible says, (Always listen to the Bible, it is the distilled wisdom of the ages, and the sages, inspired by God) to cut off and burn all of the fat, and to only eat the lean meat. All Animal fats are harmful in any amounts, and add to that some poor grade oils, like corn oil and soy bean oil, and try never to consume any of these. Please don't pick at exceptions. There are some, it is true, but these are general rules made to be interpreted to suit your own special needs or doctors orders. Always listen to your doctor.
Finally, Flour can be another killer substance. Even if it is Organic whole grain flour, it is not that good for you. It is better to eat the grain in as near to its original form as possible. When grain is beaten into powder it loses a lot of nutrients, and becomes subject to going rancid very quickly, on top of which it converts to sugar in your mouth, stomach and blood far faster than eating the whole grains. Such a sugar rush is never good for you, no matter all the clatter about you "needing" an energy boost that raising blood sugar can give you. Thus avoid white flour altogether, and take it easy on the other organic, whole grain flours as well.
The Rule is: Avoid, Avoid, Avoid, the Four Horsemen of the Food Apocalypse.
And get your Rest above all, because when you are not rested your body fails to function properly, AND you overeat, among other things. Your judgment is not intact when you are tired, especially when you are chronically deprived of rest.
And try to Fast in some form. All animals in nature Fast, and it is good for their health to do so. Nature and Nature's God are good teachers for us. An ideal Fasting schedule might look something like, (to keep it simple) one day a week, one week a month, and one month a year. Now, that is just an oversimplified estimate to give you some idea of how animals fast, and yet remain very healthy. Even one 24 hour day fast a year would be helpful, but there are very few people who even do that.
