The 7-Day Lean Challenge

If you've ever dieted, or if perhaps you've spent much of your life dieting, you've undoubtedly worked very, very hard to achieve results. And possibly experienced the devastating shame or disappointment of having the weight creep back on. Whether you've been working against 10 pounds or 200, losing weight and keeping it off can be one of the toughest challenges. What I'm here to tell you is that weight loss doesn't have to be hard!

That's why I wrote The Lean: A Revolutionary (and Simple!) 30-Day Plan for Healthy, Lasting Weight Loss, and that's why today I am inviting you to take a special 7-Day Lean Challenge.

You may be asking yourself what the Lean is all about. Well, simply put, it's about easing into change. I'm going to have you add healthier choices to whatever else you're already eating.

I'll tell you straight out: We are going to move away from eating animals and work in some delicious plant-based food, because as you'll read in my book, an overwhelming amount of science and data say that this is the way to go if you want to lose weight healthfully and keep it off for good.

In the Lean, old bad habits get crowded out by better ones. It's the old switcheroo. But the key to the success of crowding out is doing it with a fair amount of ease. Diets that are too radically different from what we're used to generally don't work. That's because we want familiarity, tradition, hearty food, good taste. We don't want a whole new life; we want our same life, only absent a few (or more) pounds. If you listen closely, you might hear your true voice admitting, "I just don't want to give up the foods I love. Period." Fair enough, and who does? Not moi. Give up pizza for steamed broccoli and broiled chicken? No thanks. How about switching out pizza for pizza, though? Now we're talking, right? You can still eat your burgers and apple cobbler. Feeling excited yet? You should be! I'm going to introduce you to healthier versions of the things you grew up loving. Better yet, you'll have even more foods to choose from. Yep, that's right -- more food!

It's important for me to say that my book The Lean is 30 days of small changes. So what you will get by taking this seven-day challenge is a very nice jump start. Consider it a test drive. These steps are not "in order," but are designed in a way so that you can get the most out of the seven days!

If you continue on to incorporate the whole program in your life (which I hope you do!) my strong hunch is that by the end you're going to be floored to see the positive benefits to your weight loss and health when you really embrace this process.

So come on, join me in taking this special 7-Day Lean Challenge!

I look forward to seeing you on the challenge.

To health and happiness,
