This nutritionally sound book-based food plan is based on the research of Barbara Rolls, PhD, professor of nutrition at Penn State University. Rolls says you can lose one to two pounds per week on the plan. The theory is that by swapping out calorie-heavy fat-laden foods with fruits and vegetables that have a lot of water in them, you can eat more for fewer calories. To boost weight loss, you will need to be active—aim for 10,000 steps a day. You might not lose weight as fast, but Rolls has both short-term and long-term evidence to support her approach. Read more about it in Rolls’ latest book, The Ultimate Volumetrics Diet.
The 3 Day Diet is low calorie, but it certainly is not low-fat, low-salt, or low cholesterol, so it is not a healthy option for most people with certain medical conditions such as diabetes, hypertension, heart disease, and high cholesterol. If you are overweight, weight loss is key to managing these conditions. But it should be a healthy and sustainable weight loss that includes healthy nutrition and exercise.
Notes: Chop the sweet potatoes and halve the Brussels sprouts, and place on a sheet pan. Drizzle with 2 teaspoons olive oil, season with salt and pepper, and toss to coat. Roast at 450°F (230°C) until tender, about 15 minutes. Brush the chicken with 1 teaspoon olive oil and season with salt and pepper. Grill over medium-high heat until marked and no longer pink in the center, about 5 minutes per side.
