This is hands down the best, healthiest, safest, most satisfying diet I’ve ever found to help you blast through fat and reach your goal weight. The Smoothie Diet was created by Drew Sgoutas, a Board Certified Health Coach and Nutrition Expert. The plan is simple. For 21 days, you swap out two of your three meals with delicious, hearty, nutrient-dense smoothies. That’s it. You can still have snacks and one whole food based meal throughout the day, and you won’t have to stress about planning them since the Smoothie Diet guide includes sample meals and snacks (plus vegetarian options). If you choose, you can use a “flex day” every week where you just eat three healthy, meals (they’re all spelled out inside the Smoothie Diet). This way, it’s very convenient.
