1. cut out extra salt, sugar, artificial sweetner, dairy, alcohol, beans/legumes and all grains (THIS INCLUDES CORN IN ALL FORMS! and rice) for 30 days.
2. Increase your intake of vegetables (try and eat a rainbow of colors). Stick with healthy starches like sweet potatoes.
3. Eat more fruit (berries are high in antioxidents)
4. Eat healthy fats like avocado, olive oil, coconut oil, tree nuts
5. Eat a variety of lean protein
6. Take a multi vitamin
7. WATER WATER WATER!!!!!! If you must, add a bit of unsweetened organic cranberry juice (get this in the natural food section or at a healthfood store. This is NOT Ocean Spray). Aim for at least 64 oz/day, more if you're exercising. Water flushes your system.
8. Green tea is lovely and gives you a nice metabolism boost with the caffeine and EGCG.
9. Sweat. Get out and move as much as possible. Your body releases toxins through sweat, urine, etc.
10. Be prepared to feel like crap (lethargic, weak, headache, moody) for the first week. Your body will legitimately detox from the garbage you regularly eat as well as the sugar and carbs. You can take milk thistle to help combat the carb detox. Keep up with the water and do whatever you have to do to get through it. Once you're past the initial hurdle (for me I feel good by day 4), you'll have energy and feel pretty amazing. Bloating from dairy and grain should subside within a week.
I've found that the Whole30 challenge is a great way to "detox" my body and get off of the caffeine/sugar wagon.
