Finding the right diet is like to going on a long road trip: Everyone wants to get there quickly, but losing weight is a journey, not a destination. Along the way you'll learn a lot about yourself, and what you discover en route could ultimately be more fulfilling, rewarding and even enjoyable than better-fitting skinny jeans.

Experts agree that the more tools and guidance you have on this journey, the smoother your trip will be. Some weight loss programs offer services like in-person coaching, full meal plans, prepackaged foods and online support. By considering the different programs, you can find the program that works best with your current lifestyle. Once you've found the right plan, commit to it. You’ll get back as much as you put into it.

What to look for when choosing a weight loss program?

Individual foods allowed on diet

Consider a diet's overall approach to food. What will you be eating every day? Is there much variety, or will you be eating the same foods frequently? If most (or even some) of the foods on a plan aren't enjoyable, within your budget, or readily available, you're going to find a particular plan hard to stick with. Ask yourself: realistically, could you eat the foods on this plan more or less for the rest of your life?

  • Preferred tastes: Think about whether the foods on a given diet are things that you generally enjoy. If you hate eating your greens, you might not like a diet filled with salads; but if you have a sweet tooth, a diet that substitutes milkshakes for meals might be more up your alley. Ask yourself whether you will enjoy the foods on a given diet, or if it will feel like a “diet” food that you won’t be able to stick with long-term.
  • Accessibility to foods: Some diet plans ship foods straight to your door, while others require you to shop for very particular ingredients. There are also a range of price points, with some diets costing substantially more than others. Consider whether the food allowed on a particular diet will fit into your budget and be relatively easy to find at grocery stores.
  • Food allergies and sensitivities: Many people have food allergies or sensitivities that could make a given diet difficult or impossible to follow. Consider whether the diet plan features potentially allergenic or reactive foods, particularly if you plan to eat the same foods daily.

Meal plans

Factor in time, convenience, and cost when determining whether a plan's meals will work for you. If you prefer home-cooked meals, packaged shakes and processed snacks aren't going to work for you; likewise, if a plan demands elaborate meals and you need convenience, you'll probably struggle with the plan.

  • Packaged meals: Many diet plans rely on meal-replacement bars, shakes, or other snack type foods. Still others rely on frozen entrees as a major part of your diet. Ask yourself if you are okay with a bulk of your diet relying on prepackaged snacks, shakes, or frozen meals, or if you prefer the flexibility of cooking your own meals or eating out frequently.
  • Lifestyle fit: Think about how much time and planning goes into each weight loss program. Some people will find that meal planning and preparation takes too long to fit into their busy lifestyle, while others will have the time to commit to a more demanding plan. Figure out whether a plan is compatible with your lifestyle before committing. Some meal plans are very simple; others require more work.
  • Caloric intake: While it is true that less calories usually means more weight loss, some diet plans are strict and can leave you feeling hungry most of the time. Additionally, some people need more calories because of metabolic issues or high activity levels, and low-calorie plans might be insufficient. Think about whether a diet plan will keep you full.

Cost and budget

Every diet plan company has a different business model, and some require an upfront sign-up or initiation fee before you can begin the program. Some diet plans also have hidden costs and other fees that become pricey. Set an approximate monthly budget, then contact customer service to ask questions about price before you commit to a plan.

  • Budget: Ask yourself how much you are willing and able to spend a month on a weight loss plan. Factor in what you get for the cost; plans that provide your meals for you will be pricier but you may save money on grocery bills in the long run.
  • Level: Many plans offer multiple tiers of service or options customized to your preferences. Consider: Do you need the basics or a more comprehensive plan? You may be able to save money by opting out of the unnecessary features of more expensive plans.
  • Monthly costs: Many programs include initiation fees, food fees or counseling fees, while others require you to buy expensive foods and/or supplements. Consider the “big picture” rather than the initial price they mention.

Community interaction

It can be difficult to lose weight and maintain a healthy lifestyle if you don't have adequate social support. Some weight loss programs offer in-person support group meetings, others offer one-on-one counseling via telephone or text messaging and still others use online message boards or forums to connect you with others using the plan.  Corresponding with like-minded people can make your fat-loss journey easier and more productive, but what level of accountability and interaction do you want or need? 

  • Counseling and community: Think about whether you need one-on-one guidance from an expert or a supportive diet-related community to succeed on a weight loss program. Some people prefer to go it alone or involve their friends or family rather than a forum, but others enjoy finding acceptance and encouragement from others who are using the same program.
  • Type of support: Every person has different needs when it comes to what motivates them to succeed. Think about how you have met other important goals, quit bad habits, or motivated yourself to change in the past. Would you be more likely to succeed using social media; in-person meetings with strangers or acquaintances; or expert counseling using text messaging, phone calls or email?
  • Community demographics: What is the demographic of this program’s community? If you’re a college male and the community is middle-aged women who meet in person, you might feel out of place. Think about whether you will fit in with the community and whether that matters to you personally.

Exercise and other lifestyle factors

Losing weight means using more calories than you take in, but whether this is accomplished soley through dietary changes or through a combination of diet and exercise will vary according to each diet plan's requirements. Some plans focus entirely on diet, while others incorporate exercise and lifestyle strategies as part of their fat-loss plan. 

  • Fitness requirements: Think about whether a diet plan has activity or exercise requirements, suggestions, or even the ability to track your daily exercise. If exercise is required, are you willing and able to do it? If it is optional, will the plan motivate you?
  • Lifestyle changes: Many people struggle with weight not only because of their eating and exercise habits, but because their lifestyles are stressful or exhausting, which makes losing weight more difficult. A plan that emphasizes quality sleep, stress control, and other tools that contribute to fat loss can help you lose the pounds and keep them off long term.
  • Personal preferences: Each weight loss program is different, and your personality, preferences and habits will impact whether or not a given plan will be right for you. Ask yourself whether you would find a plan's requirements enjoyable and sustainable, or if you would be miserable on it. Remember that pleasure is important for your success.

Long-term sustainability

While many plans emphasize quick upfront results, maintaining fat loss is just as important as losing it. Think about how the plan supports members after they've met their initial weight loss goals. Does a plan provide the tools and strategies you'll need to stay lean for the long haul?

  • Weight loss maintenance: Does this program offer a long-term maintenance plan for permanent fat loss? The program should have a specific plan in place, with specific suggestions, guidance and support.
  • Ability to continue plan: If it does, are you realistically able to stick with this plan for the rest of your life? Think about factors like price, time requirements for meal planning and preparation, satisfaction and flexibility with your lifestyle.
  • Ongoing fitness and support: Does the long-term plan provide an exercise plan, strategies to navigate specific obstacles, and other tools to enhance permanent fat loss?

Types of weight loss programs

In-person group meetings

These structured programs typically meet at a community center or brick-and-mortar business on a weekly or otherwise scheduled basis. Participants might engage in a group discussion, breakaway groups, or one-on-one sessions with other members or program counselors.

Meal delivery services

Some weight loss programs deliver meals or meal ingredients to your home, either as a part of a broader plan or as their primary service.

Online programs

Some weight loss programs rely on Internet-based forums or communities or mobile applications for meal planning, counseling and/or group interaction and support.

Meal-replacement programs

Some weight loss programs rely primarily on meal-replacement products such as shakes, bars or other snacks.

Supplement programs

Some programs primarily market a dietary supplement, powder or other ingredient designed to block fat or promote feelings of fullness instead of hunger.

Customizable plans

Some programs are flexible and allow you to choose among many different diet plans, formulating one that works for your needs and preferences. These often require more homework but provide a more custom fit than one-size-fits-all programs.

Who uses weight loss programs?

Busy adults

Most weight loss programs are designed with busy, successful middle-aged women and men in mind, especially those who have put on weight in recent years and want to get back into their “skinny jeans.” While women are often the target consumer for these products, more and more men are also turning to weight loss programs for support.

College students

Many college students and 20-somethings have always been able to eat what they want and burn it off. As they age, they may find calories landing around their midsection (e.g., the Freshman 15) and turn to weight loss programs to help them shed the unwanted weight.

Older men and women

Many older men or women who have gone through andropause or menopause begin to struggle with excess weight, and may find a weight loss program helpful.

Former athletes

Athletes at their prime must consume many more calories than the average person to be at peak performance, but as they age and become less active may find that their old eating habits are hard to break. Former athletes who have gained weight and want to become lean and muscular as they age may turn to weight loss programs for help getting on track.

New moms

New moms often struggle with shedding the excess pounds left over from pregnancy, and also have little discretionary time to spend on elaborate diet and meal plans. They may find a diet program helpful, especially one that saves time by taking the planning out of meals.

Dieters on a budget

Many individuals are looking to lose pounds and inches off their waistline, not their wallets. These customers may be looking for affordable weight loss plans to help them achieve their goals.

Kids and teens

While most kids and teens should avoid weight loss programs, some may need a well-defined dietary plan to lose excess fat and become healthier. Kids and teens should always be under the supervision of a physician before starting a weight loss program.

Dieters with food sensitivities

Whether allergic to soy, gluten, dairy or any other ingredients, some dieters want to lose weight, but may have stricter dietary requirements than others. These customers may benefit from pre-packaged meals and dietary programs that avoid certain ingredients.
