Attitude, action, and perception are all greatly influenced by your physical state...your health. For your life to be great, your health and energy have to be optimized. Here's some advice that will change everything about your life.
Eliminate all simple carbs (sugar, flour, wheat, bread, pasta, potatoes, etc) except for one day a week. No fruit either. Every Saturday, go absolutely nuts with junk food! Then that's it for the rest of the week. This is easy. Without simple carbs, you feel better and don't get hungry as often. I've been low-carb for over a decade, but I never did it consistently until I added the cheat day. This is the diet I have been on for three years now. Eat enough so you aren't really ever hungry. Follow this diet and it is a matter of time until you get to your ideal weight and stay there.
It is ok to have up to two glasses of dry red wine every night. This doesn't hurt anything. But no more (this is where I'm most likely to break the diet). :-)
Drink huge amounts of water. 3 liters per day.
Eat 3-5 cloves of raw garlic every day. Crush it, put it in your mouth, immediately wash it down with a huge glass of water without chewing it. You won't taste it and this will keep you healthy, pain-free, and free from illnesses cause by bacteria or viruses. If you do start to get a cold, eat even more garlic and drink 1-3 cartons of orange juice each day until it is gone. My last three colds, I cured in one day as the other members of my family two weeks.
Take 1,500 mg of L-Carnitine with flax seed oil and cold water as soon as you wake up each morning. Go to the supplement store and make this investment right away. read about the benefits (they are all true and very noticeable). This will completely change your life. You will feel excited about life, positive, never depressed. Take another dose in the afternoon.
Work out hard 3x per week. Take 5-10 grams of BCAA supplements 30 minutes before going to the gym. Have a black coffee with it. Choose 6-8 weightlifting exercises and perform the each, one set of 10 - 18 reps, to the point of failure...to where you can't move the weight. Your first set should be kettlebell swings. Look it up and learn it. Do 70-100 kettlebell reps until it kills you. Then do abs and the rest of your weights, waiting 3 minutes between sets to recover. When you are finished with weights, run for 25 minutes. The whole workout should take less than 1 hour 3x per week. In a month you will be a new person (if you also follow the diet). This Fall, I completely changed my body with this workout after just 3-4 weeks (12 - 15 workouts).
Eat 2-3 eggs each morning within 30 minutes of waking up. I also eat black beans and spinach with them to fill up.
Eat as much meat as you can. Avoid all dairy if possible because it spikes blood sugar just like carbs. No fruit. No sugar. No simple carbs. Veggies, meat, nuts, black coffee, water, 2 glasses wine at night. That's your life. First, break the carb addiction. Next, Learn how to cook and good food becomes delicious. Have Thai, Indian, Sashimi, whatever you want...just no rice, bread, potatoes.
Try this for a month...all of it....100% of what I'm saying....and let me know how much better your life is. :-). You will have much more energy, look better and younger, and you will THINK differently. Research all of this first if you don't believe me. But you have to do all of it or you will undermine the other parts.
