Diet pricing plans
Whether you're interested in losing weight or just want to lead a healthier lifestyle, a diet plan is a great way to achieve those goals. Some plans are better for those who can add healthy cooking into their schedules, while others cater to people who don’t even have the time to pick up a peeler.

Regardless of which kind of diet plan you choose, there's always one question everyone asks: how much is this going to cost me? Here are some of the most successful diet plans, what they’re all about, and how much it’ll really cost you to trim down and stay fit using one of these plans.

1. Nutrisystem

Nutrisystem is a great diet plan if you don’t want to think about your meals. Actually a diet meal delivery service, Nutrisystem offers you simple, calculated food options. You can just grab a bite to eat without thinking and know you are getting something nutritious every time. You won’t be asked to count calories, measure carbs, or watch your portions thanks to the ready-made food packages from Nutrisystem.


In terms of pricing, Nutrisystem is one of the least expensive meal delivery-based diet plans. It’s both a diet plan—meaning it takes care of the nutrition side of things—and a meal delivery service—meaning it takes care of all the prep and cooking. So, you’re getting health and convenience, the 2 biggest obstacles people have when trying to stick to a diet, for the price of one. 

Here’s what you can expect to pay for an average Nutrisystem plan:



Basic Plan


Pre-selected foods

Core Plan


Choose your own meals from 100+ options

Uniquely Yours


Even more menu options 150+

Uniquely Yours Plus


Full menu plus protein shakes

Each package comes with a 4-week plan and includes 6 small meals a day delivered to your door. A month of meals will average around $250-$300, very reasonable for fueling your day and your diet.

Nutrisystem Freebies

The Nutrisystem plan comes complete with free online tools and a community for support. The plans also have a money-back guarantee.

2. South Beach Diet

The South Beach Diet offers a healthier way to eat, making weight loss inevitable if you stick to the plan. A 3-phase diet, it starts out by restricting carbs and gradually adds them back in as you progress through the phases.


The South Beach Diet is an unusual diet plan in that you can opt to pay for the meals or you can go it on your own. With all of the information based on Dr. Agatston’s research, you can technically do the entire South Beach Diet for free. This is an ideal option if you are super motivated, have time to prepare and cook healthy meals, and can follow a strict diet plan. 

Alternatively, if you aren’t any of those things, you can still meet with success using the South Beach Diet meals. These include everything from delicious breakfast options to mouth-watering snacks. This can be a better route for anyone who doesn’t have the time or patience to cook and maintain a healthy diet on their own. In addition to the meals, the South Beach Diet comes with free weight loss tracking tools, recipes, and money saving tips.


The South Beach Diet costs between $10.71-$13.39 per day, depending on which plan you choose. The 3 levels, Silver, Gold, and Platinum, offer more menu options as well as snacks to choose from.

3. Mayo Clinic Diet

The Mayo Clinic Diet was created by medical professionals, so it’s more about encouraging a healthy shift in your lifestyle. It’s not just about limiting calories or denying yourself that decadent chocolate cake. According to the Mayo Clinic Diet philosophy, if you can create healthy living habits, you’ll arrive at your healthy weight naturally and maintain it with ease.

What’s even more interesting about this diet plan is how many aspects of your lifestyle it takes into consideration—do you eat in front of the television, how active are you, and what is your current weight loss motivation, for example. Once you’ve answered these questions, you’ll get a tailored diet profile that helps you combat your own unique hang-ups and keep your motivation going stronger and longer until those healthy habits are formed.


At just $5 per week, the Mayo Clinic Diet aims to be affordable for all. While this doesn’t factor in all the money you’ll be spending on groceries, it’s still one of the cheapest diets you’ll find.


Weekly Plan

$5 per week

Quarterly Plan

$65 per quarter


In addition to an already low membership fee, the Mayo Clinic Diet provides extra perks including 24/7 support from health professionals and dieticians, habit tracking apps, fitness planners, and more. The online and phone support are particularly impressive because they can help overcome emotional triggers and stressful situations that generally lead to a spike in weight gain.
