Indeed! I've heard people say it numerous times: "That's OK, I'll just take a calcium pill when I get home." Instead of eating veggies that are loaded with calcium.
Admit it. You're addicted to junk food! Now, take the 6 week challenge: Eat nothing but whole foods on a plant-based, animal-free diet for 6 weeks. I'll bet you feel better. And at the end of 6 weeks, when you try some of the stuff you used to eat, you'll be amazed at how bad it tastes. You will feel the oil coat your tongue and the sugar and salt will jump on your taste buds. You won't like it anymore...
