9 Top Entrepreneurs Reveal Their Health Regimen Secrets Look half your age, feel great and crush the competition with these health secrets.

The best entrepreneurs know that in order to crush business, your body needs to be bulletproof. These members of The Oracles have engineered their bodies to feel half their age and perform at the highest levels. Here are their secrets.

1. Juice up.

Get yourself a good juicing machine. There are more people drinking a sugary Big Gulp today than drinking 32 ounces of vegetable and fruits. Juicing daily is an investment in your greatest asset—your body. I want control over my vehicle (body) and that starts with my diet. Lean meats, salads and workouts help me stay energetic all day long. —Grant Cardone, top sales expert who has built a $500 million real estate empire, NYT bestselling author of Be Obsessed or Be Average, and founder of 10X Growth Con 2017; follow Grant on Facebook or YouTube

2. Focus on the most important 80 percent.

My mom used to say: it's not what you eat 20 percent of the time that kills you, it's what you eat 80 percent of the time. Friends who aren't entrepreneurs probably have more time than you do to go to the gym seven days a week. Focus on 80 percent of that, which is five days a week. If they never eat junk food because they're trying to get steel abs, just try to eat 80 percent of the day's meals correctly.

Bradley Martyn, one of the top fitness guys in the world, told me that the best diet is the one you'll actually stick to. If a diet says only eat salmon all day, but you hate salmon, even if it gets you in great shape, you're not going to stick to it. —Tai Lopez, investor and advisor to many multimillion-dollar businesses who has built an eight-figure online empire; connect with Tai on Facebook or Snapchat

3. Compress your eating window.

I eat in a compressed eating window between 1 p.m. and 7 p.m. daily to remain in a fasted state for 18 hours virtually every day. My Primal Big Ass salad at midday is my go-to dietary centerpiece. It has an assortment of veggies, nuts and meat, and of course Primal Kitchen salad dressing. I eat whatever I want and I never eat anything I don't like.

I only make supplement products that I need and use myself—that's the driving principle of my business. Hence, I take the specialized products in my product line: a comprehensive multivitamin/mineral/antioxidant formula, an omega-3 supplement, a probiotic, a high-protein, low-carb meal replacement powder, a phosphatidylserine supplement when I'm under heavy stress, and Vitamin D in the wintertime. Being "strict" is highly overrated; I allow for tremendous flexibility in my daily routine. —Mark Sisson, founder of Primal Blueprint, bestselling author of The New Primal Blueprint, and publisher of MarksDailyApple.com, the world's most visited blog on paleo, primal, and ancestral health

4. Fuel your productivity. Prioritize sleep.

I usually skip breakfast, so I can fulfill my 16-hour fast to help me burn fat and stay energized. I'll have the occasional black coffee—high-altitude Arabica beans are better than instant coffee. Lunch and dinner typically comprise of lean meats like chicken with vegetables or salads. I'll snack good fats like raw almonds and avocados to balance my blood sugar and maintain concentration. In the evening, I wear Swannies blue-light blocking glasses. That way, I can work or socialize in the evening and still get a great night's sleep. (Artificial blue light from electronics or bright light disrupts your sleep.) This rejuvenates my brain so I can wake up with focus and clarity, which enables me to work efficiently in the morning. — James Swanwick, entrepreneur, author, and CEO of Swanwick Sleep and the 30-Day No Alcohol Challenge

5. Discipline your diet, discipline your life.

The biggest shift in my life occurred when I stopped looking at food as filler and started thinking about food as fuel. You have to put nutritional value before convenience. Stop filling your shopping trolley with stuff that is packaged or processed. Instead, reach for leafy greens packed with dense nutritional value. You can get all the vitamins and nutrients you need naturally without having to reach for a supplement. If you can find discipline in your diet, you will be amazed at the discipline you can unlock in the rest of your life. —Josh Black, entrepreneur, author of Personal Best, and CEO of GroupM Content in Asia; GroupM is a media investment group with more than $100 billion in billings

6. Engineer energy and focus.

I have the lives of my patients in my hands every day. I need to be focused. Every morning starts with a full glass of water to hydrate myself, and then it is coffee time. In my organic coffee, I blend MCT oil, collagen peptides and an almond milk creamer. My breakfast usually includes coconut yogurt parfaits, chicken sausages and smoothies. Every morning, I take a multivitamin with minerals, fish oil, probiotic, CoQ10 Ubiquinol, and vitamin D. My supplement regiment takes into consideration that I am a competitive athlete with a challenging workout regimen.

I eat a light breakfast and lunch, then I crush dinner. Eating large meals activates the parasympathetic part of your nervous system, which makes you tired. Eating light during the day with a larger meal in the evening allows me to be energized during the day and tired at night. I stick to my diet 90 percent, because it's impossible (or impractical) to be perfect. —Dr. Nick Zyrowski, founder of NuVision Excel

7. Eat light and drink phytoplankton.

Upon waking, I drink a liter of micronized water with two droppers of Oceans Alive Marine Phytoplankton to flush the body with nutrients. Then, I use 30 sprays of EASE Magnesium on my abdomen and lower back after I shower. I repeat it all again 12 hours later. No stimulants (coffee, chocolate, caffeine teas) ever. These are fake energy, and you'll have far more short- and long-term energy without them. — Ian Clark, founder and CEO of Activation Products

8. Everything in moderation.

I don't have fatty foods often. I stay away from gluten. I make sure I have small meals throughout the day. If I decide to eat chips (my favorite), I grab a handful and put them in a bowl. I never put the whole bag in. Everything in moderation. —Jay Georgi, founder of Nadvia and operations / management / profits-retention coach

9. Get outside first thing.

At first light, I surf or exercise on the beach. Exercising in nature starts my day in the most positive way. On the way back home, I pick flowers for my wife. That ritual of making yourself and your partner happy creates an unstoppable day. —Brian Swan, co-founder of Unstoppable Family
