Eat, Drink and Weigh Less: Walter Willet and Mollie Katzen


Eat, Drink, and Weigh Less is written by Walter Willet, M.D, head of the department of nutrition at the Harvard School of Public Health, and Mollie Katzen, author of the New York Times bestselling Moosewood Cookbook.

The goal of the authors is to present dieters with nutritional advice that is based on up-to-date research, while at the same time providing healthy recipes that taste great.

Walter Willett Diet Basics

There are nine basic principles outlined in the book that will help you to improve your diet and follow a healthy lifestyle:

  1. Eat mindfully
  2. Consume more fruit and vegetables
  3. Choose foods that contain healthy fats
  4. Upgrade your carbohydrates
  5. Select mainly vegetarian sources of protein
  6. Drink a lot of water
  7. Consume alcohol in moderation
  8. Take a multivitamin
  9. Exercise every day.

The Eat Drink and Weigh Less plan is based largely on the Mediterranean diet with some adjustments to make it easier to follow and to support weight loss. You are encouraged to eat a plant-based diet because this is better for your health, but animal products including fish, low-fat dairy and lean meat are permitted in moderate amounts.

Dieters are provided with a 21-day program that includes recipes that emphasize whole foods such as fruit, vegetables, legumes and grains. You will need to prepare most of your own meals but if you don’t have the time you can have a “fallback meal”, which contains a portion of protein, two or more green vegetables, one orange vegetable and a serving of whole grains.

Walter Willett  and Mollie Katzen encourage dieters to eat breakfast every day and to limit the intake of dessert to an occasional treat. If dieters enjoy wine they can drink one glass a day because moderate intakes have been associated with a positive effect on health.

Recommended Foods
