How to Choose a Structured Meal Plan or Diet Program: What to Check
Questions to ask before you join a structured meal plan or diet program, what NIDDK says a program should include, and the ad promises the FTC calls false.
Key takeaways
- NIDDK says a weight-loss program should include a healthy, reduced-calorie eating and drinking plan, a plan for increasing physical activity if appropriate, guidance and support for adopting these lifestyle habits, and a plan for keeping the weight off.
- Ask for the total cost from beginning to end. NIDDK suggests asking about costs not included in that total, such as membership fees, food, meal replacements, medical tests, counseling sessions and follow-up.
- Check the menus against the Dietary Guidelines for Americans, and ask whether you can change foods for allergies, culture or preference.
- The FTC lists "You can lose 30 pounds in 30 days" and "This product works for everyone" among the false promises often seen in weight loss ads.
- No program can promise you a result. Talk to your doctor or a registered dietitian before you start, especially if you have a health condition, take medications, are pregnant, or have a history of an eating disorder.
A structured meal plan or diet program can give your week some shape, but programs differ a lot in what you get, what they cost, and who stands behind them. This guide gives you a set of questions to ask before you pay, and the claims to treat with suspicion. It does not promise any result, and neither should a program you choose.
What a program should include
NIDDK says a weight-loss program should include a healthy, reduced-calorie eating and drinking plan, a plan for increasing physical activity if appropriate, guidance and support for adopting these lifestyle habits, and a plan for keeping the weight off. Use that list as a checklist against whatever a program offers.
Most programs lean on one or two of these. If a program only sells food, ask what support comes with it. If it only sells coaching, ask what the eating plan actually is.
The questions worth asking
The questions in the table below come from NIDDK’s list of questions to ask program staff. The last column is our own suggestion for what a clear answer looks like.
| Ask about | What to ask | What to listen for |
|---|---|---|
| Evidence | Has the program been formally studied to find out if it is safe and effective? Have results been published in a scientific journal? | A straight answer and a copy or link, not only testimonials |
| Cost | What is the total cost from beginning to end? Are there costs not included in that total? | A full list of fees, food, meal replacements, tests and follow-up |
| Eating plan | Do you need to follow a specific meal plan or track what you eat each day? Can you make changes? | Room for your likes, dislikes, cultural preferences and food allergies |
| Support | Is there one-on-one or group counseling, or a trained coach? | Help with roadblocks, stress, work schedule changes and setbacks |
| Staff | Does a doctor or other certified health professional run or oversee it? What training do staff have? | Named credentials and a professional you can reach |
| Safety | Could the program cause health problems? Is there ongoing follow-up to ensure your safety? | Staff who will work with your own health care professional if needed |
| After the program | Is there a maintenance plan? How long is it and what does it include? | A defined follow-up plan, and what it costs |
Write the answers down. If a program won’t answer, that tells you something too.
Do the meals follow the Dietary Guidelines?
Ask to see the actual menus, not just a description. Then compare them with the Dietary Guidelines for Americans, whose home page tells readers to “prioritize whole, healthy, and nutritious foods.” Look at whether the menus are built mostly from everyday foods such as vegetables, fruit, whole grains, protein foods and dairy, rather than a narrow list of the program’s own products.
Two practical checks help here. First, can you read the full nutrition facts and ingredients for every meal before you order? Our guide to building a balanced plate shows what a mixed plate looks like. Second, can the program handle allergies, cultural food traditions and your own preferences? NIDDK suggests asking whether you can make changes based on your likes, dislikes, cultural preferences and any food allergies.
What the program includes and who supervises it
Programs come in several formats. The tabs below describe each in general terms, with no particular company in mind.
Meal-replacement programs
These swap some meals or snacks for packaged shakes, bars or similar products that the program supplies. Ask which meals are replaced, how long you are expected to use them, and what the plan is for returning to regular food. NIDDK suggests asking whether you have to buy special meals or supplements and, if so, what the daily or weekly costs are. Review this type of program with your doctor before you start.
Meal-delivery programs
These send prepared meals or meal kits on a schedule, often as a subscription. Check the menus against the Dietary Guidelines, whether you can pick your own meals, and the price per meal after any intro offer. Then read the pause and cancel terms. Our guides on choosing a healthy meal delivery service and the real cost of a meal kit go deeper, and you can browse options on the meal delivery comparison page.
App or coaching programs
These deliver a plan, tracking tools or one-on-one coaching through a phone or website. Ask who the coaches are and what training they have, how often you actually talk to a person, and what data the app collects. NIDDK suggests asking how a program is delivered (in person, online or by smartphone) and whether you can change it to meet your lifestyle, work schedule and cultural needs. It also notes that digital programs are still being researched. Our guide to choosing a nutrition app covers the app side.
Whatever the format, ask who supervises it. NIDDK suggests asking how long, on average, most staff have been working with the program, along with the staff questions in the table above.
Total cost and subscription terms
The price on the sign-up page is rarely the whole price. NIDDK suggests asking for the total cost from beginning to end, and whether there are costs not included in that total, such as membership fees or fees for weekly visits, food, meal replacements or other products, medical tests, counseling sessions, follow-up and online chat access.
If the program is a subscription, also read how billing works. The FTC explains that a negative option is when you’re automatically billed for something when you didn’t specifically say not to bill you. Before you give your credit card, it advises reading all the details, looking for pre-checked boxes and making sure you know how to cancel. It also notes that an automatic renewal might charge more than you paid the last time, for example if you started on a promotional rate.
Watch “free” offers too. The FTC’s weight loss ads page says “free” trial offers are often not free at all. When you are ready to leave a program, our guide to pausing, skipping or canceling a meal subscription walks through the steps.
Red flags in the ads
The FTC’s page on weight loss ads lists these as false promises you’ll often see in weight loss ads: “Lose weight without dieting or exercising”; “You don’t have to watch what you eat to lose weight”; “If you use this product, you’ll lose weight permanently”; “To lose weight, all you have to do is take this pill”; “You can lose 30 pounds in 30 days”; “This product works for everyone”; and “Lose weight with this patch or cream.” The same page says any promise of miraculous weight loss is simply untrue.
NIDDK lists warning signs of its own: promises such as “Lose 30 pounds in 30 days!”, very small print, asterisks and footnotes, and before-and-after photos or personal endorsements that seem too good to be true. NIDDK suggests talking with your health care professional about these types of claims.

Frequently asked questions
Who should run or oversee a diet program?
NIDDK suggests asking whether a doctor or other certified health professional runs or oversees the program, whether you can speak with one if you need to, and whether experts such as a registered dietitian, mental health counselor or exercise physiologist are included. Ask about staff certifications, education, experience and training.
Is a program with before-and-after photos trustworthy?
Not on that basis alone. NIDDK lists before-and-after photos or personal endorsements that seem too good to be true as a warning sign, and the FTC lists "This product works for everyone" among the false promises often seen in weight loss ads.
What should I ask about cost?
NIDDK suggests asking for the total cost from beginning to end, and about costs not included in that total, such as membership fees or fees for weekly visits, food, meal replacements or other products, medical tests, counseling sessions, follow-up and online chat access. Also read the subscription and cancellation terms before you pay.
