The HMR program’s approach makes the top of the list of best diet plans because the Decision-Free plan suggests you can lose up to 66 pounds in 26 weeks. You could also drop 37 pounds on its Healthy Solutions option. The Decision-Free diet is a medically supervised, very low-calorie diet of shakes and snacks; Healthy Solutions includes shakes, snacks, entrees, and your own fruits and vegetables. You should expect to exercise plenty to lose the most weight; you can also sign up for health coaching to boost success. The convenience is a plus—but you will get a very limited choice of foods and aren’t allowed to drink alcohol or eat out. And remember: You risk gaining weight once you go back to real food. Check out these 42 tips for losing weight fast.
This high-fat, adequate-protein, low-carb fad diet sends the body into a state of ketosis, in which the body uses stored fat for energy. Research published in Clinical Cardiology suggests the ketogenic, or “keto,” diet can be an effective weight loss method, but to be successful, you must follow the plan consistently with no cheat days — otherwise, you’re just eating a high-fat diet that may be high in unhealthy fats for no reason.

Cortisone as an oral drug is another common culprit (e.g. Prednisolone). Cortisone often causes weight gain in the long run, especially at higher doses (e.g. more than 5 mg Prednisolone per day). Unfortunately, cortisone is often an essential medication for those who are prescribed it, but the dose should be adjusted frequently so you don’t take more than you need. Asthma inhalers and other local cortisone treatments, like creams or nose sprays, hardly affect weight.
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.
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.
