What features matter most?

Individual foods allowed on diet

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: Am I going to enjoy this food or will it feel like a “diet” food that I won’t be able to eat long-term?
  • Accessibility to foods: Will this food fit into my budget and be relatively easy to find at grocery stores?
  • Food allergies: Is this a potentially allergenic or reactive food, particularly if I eat it frequently? (e.g. Soy, Dairy, Eggs, Gluten)

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 shakes 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: Am I okay with prepackaged meals and/or shakes or do I need “real” meals?
  • Lifestyle fit: Can I feasibly do this plan with my lifestyle? Some meal plans are very simple; others require more work.
  • Caloric intake: Will the meal keep me full considering my metabolic requirements? Some meals might be too low in calories for athletes and other active folks.

Cost and budget

Be wary of “initial cost” advertisements and initiation fees. Most diets have hidden costs and other fees that can make some plans become pricey. Set an approximate budget and ask questions (most plans have customer service) before you commit to a plan.

  • Price: How much am I willing to spend a month on this plan?
  • Level: Do I need the basics or a more comprehensive plan? (Many plans offer multiple options)
  • Monthly costs: What is the overall cost I will be spending a month for this program? Many programs include initiation fees, food fees, etc. while others require you to buy expensive foods and/or supplements. Consider the “big picture” rather than the initial price they mention.

Community interaction

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/need?

  • Counseling: Do I need a supportive diet-related community to succeed on this program? (Some people prefer to go it alone or involve their friends or family rather than a forum)
  • Type of support: Do I succeed better with in-person or online support?
  • Community demographics: What is the demographic of this program’s community? If you’re a college male and the community is middle-aged women you might feel out of place.

Exercise and other lifestyle factors for fat loss

Some plans focus entirely on diet, while others incorporate exercise and lifestyle strategies as part of their fat-loss plan.

  • Fitness requirements: Does this plan include an exercise plan, and if so, am I able and willing to do it?
  • Lifestyle changes: Does this plan emphasize quality sleep, stress control, and other tools that contribute to fat loss?
  • Personal preferences: Am I able to enjoy this diet or will it feel cumbersome and miserable? Remember that pleasure is a nutrient!

Long-term sustainability

Maintaining fat loss is just as important as losing it. Does a plan provide the tools and strategies you need to stay lean for the long haul?

  • Weight loss maintenance: Does this program offer a long-term maintenance plan for permanent fat loss?
  • Ability to continue plan: If it does, am I realistically able to stick with this plan for the rest of my life?
  • 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?

These structured programs typically meet at a community center or brick-and-mortar business on a weekly or otherwise scheduled basis

Very busy, successful middle-aged women and men who have put on weight in recent years and want to get back into their “skinny jeans”

What do the experts have to say?

  • Nutrisystem

    In 1999, Nutrisystem moved from brick-and-mortar centers to Internet and mail order. You can find their products on QVC and Costco, and Kroger sells their “Everyday” breakfast and snack lines. Recently Walmart began carrying a five-day Nutrisystem “Jumpstart” line. Addressing different demographics for fat loss is good, but this is simply a low-calorie diet filled with some potentially problematic foods for people with certain food sensitivities.

    What consumers say

    Nutrisystem gets generally good grades from ConsumerAffairs readers. Claire of Palmerton, Pa., reported losing 40 pounds in seven months while Jim of Hiawatha, Ia., dropped 44 pounds in seven months.  Read more consumer reviews here. A few years ago, ConsumerAffairs reporter Joe Enoch tried Nutrisystem and lost 13 pounds in 28 days.

    • Separate plans: Nutrisystem offers separate plans for men and women, with different options and price points. Looking beyond the “one size fits all” plan, Nutrisystem would work well for anyone on the go who demands fast, satisfying meals for weight loss.
    • A diabetes plan: With meals containing 12 grams or less of sugar, Nutrisystem takes the guesswork out of choosing optimal low-glycemic foods to stabilize blood sugar -- which could be good for people with any degree of insulin resistance.
    • Convenience: Any busy person who does not have time to prepare their own meals would benefit from having frozen and other pre-packaged meals and snacks delivered to their home.
    • Transition and maintenance plan: This program provides long-term fat loss success rather than just focusing on initial weight loss, which is important for those who need to establish lifelong healthy habits.
    • Processed foods: Many of the foods they sell are processed and might be too high in sugar for some people. Even though sugar content is fairly low, remember that ALL carbohydrate breaks down to sugar in your body.
    • Carbs: Because Nutrisystem allows 6 meals a day, a person’s insulin levels might stay high which could prevent fat loss. This could negatively affect anyone prone to sugar/carb cravings or someone with any degree of insulin resistance such as the elderly or new moms who struggled with gestational diabetes.
    • Best for College students, busy adults and new moms.
  • Medifast

    Developed by a physician, Medifast takes the guesswork and planning out of dieting by providing full meal plans for adults, teens and those with special dietary needs.

Their special needs meal plans can be customized for diabetes patients, nursing moms, those with gout, teenagers, seniors, vegetarians, those with Coumadin (warfarin) and people with gluten intolerance.Medifast certainly sounds doctor-endorsed, and though they provide a variety of studies to support their meal plans, recently government agencies sued because their 5 & 1 Plan low-calorie diet claimed could "lose up to 2-5 pounds per week,” yet Medifast couldn't provide scientific evidence to support that claim. The key principle for Medifast are their over 70 meal replacements, which include macaroni and cheese, brownie soft bake and Dutch chocolate shake.
