21-Day Flat Belly Meal Plan

Get flatter abs and a fitter body with this menu.

Chicken, Broccoli, and Asparagus Stir Fry

Flat bellies are fab. But they’re not just for celebrities with access to trainers and nannies. You can slim your middle, too, and our 21-day flat belly meal plan is a delicious place to start.

This flat belly meal plan incorporates foods that will help trim the waistline. Some foods, like salmon and chicken, offer protein to build muscle tissue, which burns more calories than fat tissue. Healthy fats, like those found in avocados, are an important part of this meal plan too because they boost belly fat burn.

We’ve also included fruits, vegetables, and whole grains to offer fiber that will satisfy the appetite. Foods for a flat belly that include fiber provide another important advantage: they keep the digestive system moving, combating the constipation and bloating that makes the waistline look like it belongs on that big white dough boy.

Like all our weight loss menus, this flat belly meal plan is flexible. Don’t like artichokes? Swap out an artichoke-based meal with one of our many Healthy Recipe Ideas. Have lots of unexpected leftovers from dinner? Feel free to enjoy them for a slimming lunch or dinner the following day.

    1. You can omit the salmon in the Protein Salmon on Toast recipe and substitute lean white meat chicken in the Black Pepper Salmon and Avocado Salad recipe.

      1. How much weight will you loose if you follow this diet? Say I’m trying to loose 10 pounds? Do I still follow this recipe?

  1. do you have an approx calorie count? just an average is fine….is it around 1000/day? 1500/day? only curious because im nursing and dont want to restrict calories TOO much! thanks!

    1. If you have the time, click on each recipe and get the calorie count then add up a total count. Keep in mind this does not include any snacks, which would be additional
      calories.

  2. I’ve looked thru some of the recipes and they look fabulous! The ones I seen will work with the 21 Day Fix Plan, are they all Fix Approved?

    1. We’re glad you like our recipes! They weren’t created with the 21-Day Fix Plan in mind, but they are all made with 100% clean ingredients– nothing processed.

    1. We spent about $300 the first week as we needed to stock up on the pantry items. This was at Wegman’s in SE PA

    1. Whitney, are you referring to the Spinach and Artichoke Chicken recipe in our 21-Day Flat Belly Meal Plan? Asparagus, broccoli, or mushrooms will work.

      1. Quick question, i am looking at this 1st week grocery list and i notice some of the recipes have ingredients that are not even included on the list? Is this list following the recipes given.. Like cream cheese provolone and parmesan cheese artichokes… ?

        1. Renee, We are reviewing the grocery list and will make any necessary changes. If changes are made we will change the updated download. Thank you so much.

  3. I understand that this 21 day plan is to cut belly fat but do you have an appropriate weight loss one can expect to lose? It sounds great I can’t wait to get started!!!

    1. While we are confident that you will lose inches on this plan, it’s impossible to predict how much that will show on the scale because there are so many individual factors involved. Decreasing the size of your belly will just be an added bonus to the fabulous changes that will be happening on the inside. (Think: more energy, longer life-expectancy, better health)

  4. Is there anything that I could sub for the avocado? I think I may be the only person on earth that does not like it.

    1. Are you referring to the Avocado, Cucumber, and Tomato Salad recipe? Feel free to omit the avocado from this recipe, or replace with artichoke hearts.

  5. For the peanut butter and fresh raspberries, are you really supposed to eat 4 slices as the recipe calls for? That seems like a lot.

  6. Denise, I am the other person in the world who doesn’t like avacado….the texture usually makes me gag. Just thought you would like to know you are not alone.

  7. Is this plan in addition to working out, or would I see results staying with the lifestyle that I have now? (I do not work out, but don’t eat very healthy either).

  8. Can I substitute chicken or something else for the turkey in “The Open-face grilled turkey burger”? Turkey makes me sick :-(.

  9. I’d really like to get this diet started. I have a large amount of weight I am wanting to lose as well as needing to get myself into a healthier routine. For someone who is starting out completely as a beginner, is this diet a good way to start?

    Thanks!

  10. I’m still in school and need to be able to take the lunches on the go what would u suggest as a substitute for the warm foods something like salad??

  11. Hi,
    I was wondering if I could sub any of the breakfast choices for the yogurt breakfasts. I am not a fan of yogurt, but like the way this plan looks.

    Thanks!

  12. Wow! You took a lot of time to put this together. This is great! I’m starting the plan right away. I like that i can follow a schedule of foods. I need that type of structure!

  13. Hi SkinnyMs. Can you please cone up with a diet plan for vegetarians that means no egg fish and meat but includes milk and milk products? Waiting eagerly for yr reply…

  14. Hello Dear
    I am trying since 3 month to make a healthy diet to lose 6 kilos
    With my dietitian I ve tried many types , like protein diet or a diet based on fish any many more but nothing changed
    I do all type of medical test to see if there’s any problem but ther is not
    Can you please help I am really disappointed
    Thank you

  15. do you have to have to follow the plan exactly or if there is one breakfast you like can you have that everyday? Same with lunch?

  16. I have an allergy to fish and seafood… Any instance where those take place should I just sub with white chicken breast?

  17. Hi Gale
    This is Amar from India.
    I am vegetarian so i can’t follow this diet plan.
    So please help me and make a vegetarian diet plan for me.

  18. I hope when you were answering Myaline’s question you meant to drink real water and NOT sugary drinks. I like most of your suggestions. I had been maintaining my weight for almost 3 years. I fell off the wagon over the holidays. I’m hoping this diet will jump start me back into eating healthy.

    1. Rosemary, We never recommend sugary drinks, only real water or fruit infused water. You’ll do great with you healthy eating!!!

    1. Ruth, The entire meal plan doesn’t have a print function. You can copy and paste it into your own document.

      If you want to print individual recipes, there
      is a print function inside the recipe box, top right. 🙂

  19. I don’t have much time in the mornings for breakfast… Is it ok to substitute the quicker breakfasts for the ones that require more cooking? I’m quite accustomed to simply eating an English muffin for breakfast everyday of the week !

    1. Rachael, An English muffin doesn’t provide all the nutrients needed. We recommend a more hearty breakfast to take you into mid morning.

  20. Hello
    I keep following your website, n it’s really helpful olways but as I m completely pure vegan, I don’t even eat eggs so really can’t follow any of your meal plan even if I want to follow, so request can you please create any meal plan for weight loss which is completely vegan, as I m from India so there is too much difference between your food habits n ours, so please please please can you create a vegan plan for weight loss. Request

  21. Can I eat raw oatmeal each morning and still have the same results? I have fairly high cholesterol and I am trying to reduce my number.

  22. Just found your meal plan – I am giving it a try this week and next. Just wondering – on top of the recipes and suggested meals for breakfast, lunch and dinner, are there any snacks allowed? If so, where can I find a list and recipes of them?

  23. I have been trying these recipes and I am very pleased with taste and the fact feeling more energetic. Thank you.

    Stacey from PA

    1. Hi Shirley, feel free to search and browse the site! We have several low carb and low/no sugar recipes including meal plans!

  24. Hi! You said in the comments (2016) that there would be a grocery list coming soon – have you made that out yet? Just curious… thanks! This diet plan sounds delicious. Also, instead of plain greek yogurt, is vanilla greek yogurt ok? I can not eat plain – it tastes like sour cream and while I like it mixed in recipes, I can not stomach it alone.

    1. Hey Randee,

      The 21-Day Flat Belly Meal Plan is the very next grocery list on our “to-do” list. We just posted the “28-Day Weight Watchers Meal Plan Shopping List” though! You don’t have to be on weight watchers to participate in it either. It’s full of delicious and nutritious recipes! Maybe try that one out as we work on the 21-day flat belly shopping list! Keep checking back! Thanks! 🙂

  25. Is there a printer friendly version of this plan, with recipes? If so, please point me in the right direction.

    1. Krista, We don’t currently have this as a download. You can copy and paste into a word document, but each recipe will have to be clicked on.
