Wonderslim Reviews

WonderSlim is a weight loss program or management plan specializing in healthy and effective weight loss programs. Their various meal replacement options are designed for people of all genders, ages, and fitness levels who want to lose weight quickly. As a Weight Loss Program, WonderSlim provides packaged meals with fewer calories and high protein to help those who want to lose weight.

Wonderslim takes care of the healthy eating part for you. There are a variety of low-calorie foods you can choose from. It is an opportunity to live a more healthy lifestyle. WonderSlim diet Plan users can lose significant weight without rigorous physical exercise. However, the speed at which they lose weight may depend on their abilities. But if you stick to the plan, you will see results. And there is a diabetic 1500-calorie meal plan that is high in fiber and considerate of blood sugar levels. Wonderslim is for people who practice low-calorie intake and are considering a long-term weight loss basic plan with no side effects.

How Does WonderSlim Work?

Eat the foods you love. 

1. Meal Replacements

WonderSlim philosophy is "meal replacement". The more high-calorie, over-sized, unhealthy meals you replace with their specially designed, portion-controlled meal replacements, the more weight you lose.

2. The Power Of Protein

WonderSlim & BariWise meals are packed with protein - to help ALLEVIATE cravings, BURN body fat and INCREASE energy.

3. Eat Every 2-3 Hours

You’ll eat 6 times a day, to keep your metabolism running at peak efficiency.

Menu Variety of WonderSlim

WonderSlim is a private-label brand. Its offerings are made up of high-protein bars, shakes, snacks, desserts, drinks, entreés, and breakfasts, and it’s owned by a company called Diet Direct. You’ll get the option of 4, 5, or 7 WonderSlim meals per day depending on which plan you choose. With each plan, you also get proposed meal times. These include breakfast at 7 am, a morning snack at 10 am, lunch at 12:30 pm, an afternoon snack at 3 pm, dinner at 6 pm, and dessert at 8 pm. That seems like an unnecessarily large number of meals. However, it seems like the goal is to eat many smaller meals throughout the day to stave off hunger and cravings and prevent overeating.

Most WonderSlim products will require you to add some water or milk (depending on the dish) and, if necessary, a few minutes in the microwave or on the stove.

Can I Custom My Own Meal?

WonderSlim doesn't allow you to add or remove ingredients from existing meals, but you have complete freedom to choose your own meals. WonderSlim has an a la carte system, whereby you choose the number of meals assigned to the selected plan.

WonderSlim is a bit more flexible, and you can choose between one of the 3 weight loss programs (each available in 2-, 4-, 8-, and 12-week plans) or you can order any product you want, in any quantity, at any time – just like you would from an online store.

WonderSlim has options for a wide range of dietary needs such as vegetarian, diabetes-friendly, keto, paleo, low-sodium, and so on. WonderSlim’s menu can also be filtered pretty extensively. You can get options for high-protein, low-carb, keto-friendly, low-fat, bariatric, kosher, lactose-free, and tons more.

In terms of allergies, WonderSlim doesn't cater to any, specifically. If you have mild allergies, or simply prefer to avoid certain ingredients, make sure to read the menu labels carefully. If you have severe, life-threatening allergies, it’s best to avoid WonderSlim.

Optavia Reviews

OPTAVIA is a low-carbohydrate, low-calorie lifestyle program designed for weight loss. Derived from the Medifast diet, OPTAVIA relies heavily on prepackaged foods, referred to as Fuelings, in combination with home-prepared recipes.

Subscribing to the plan will also give you access to an independent coach who can help guide your OPTAVIA journey. Many commercial weight loss plans sell very similar products – bars, shakes, dry soup mixes and more. If you’re a chronic dieter, some of these will undoubtedly taste familiar to you.

In 2023, the company introduced OPTAVIA ACTIVE, a new line of supplements for active individuals that include amino acid supplements and protein powders. These products are intended to be used in addition to the existing weight loss plans to support healthy muscle growth during aging and support overall health through physical activity.

Overall, the Optavia diet provides packaged foods that you can cook or eat prepared. They offer low calorie and reduced-carb meals, as well as help you lose weight with personalized coaching. The exact food you get will depend on your choice of plan.

How Does Optavia Work?

The diet company relies on meal replacements called "fuelings," which are branded products designed to keep you full until your next fueling. No matter which meal plan you choose, you'll be eating every 2 to 3 hours, resulting in six meals a day. However, one to three (depending on your plan) meals will be a dish you make at home using fresh ingredients. 

The program also recommends avoiding alcohol, sugary drinks and desserts, high-calorie condiments, starchy vegetables and whole grains. Each fueling product contains around 100 to 150 calories. Optavia's minimal-calorie diet has clients consuming about 800 to 1,100 calories a day, depending on the plan and number of homemade meals. 

According to the USDA's dietary guidelines for adults, women should consume 1,600 to 2,200 calories per day, and men 2,200 to 3,000 calories. This calorie deficit causes rapid weight loss at the start of the diet. Health professionals recommend a 500-calorie deficit for healthy weight loss. Always consult with your doctor before making changes to your diet to ensure you're consuming enough calories.

Menu Variety of Optavia

At least half of any Optavia diet consists of its "fuelings," which include bars, shakes, cookies, cereal and some savory options, like soup and smashed potatoes. These processed foods often list soy protein or whey protein as the primary ingredient.

"Lean and green" meals fill out the rest of the diet, which requires you to shop and prepare via meal prep sessions on your own time. Those include:

• 5–7 ounces of cooked lean protein like fish, chicken, egg whites, turkey or soy

• 3 servings of non-starchy vegetables like lettuce, greens, celery or cucumbers

• Up to 2 servings of healthy fats like olive oil, olives or avocado

The Optavia advises eating six or seven times per day (about every two to three hours) depending on the chosen plan. 

Can I Custom My Own Meal?

2. Optimal Weight 4 & 2 & 1 Plan: starting at $395.15/mo

You'll eat a set number of prepackaged Fuelings each day and one or two low-carbohydrate meals, which you prepare using food from the grocery store.

• an app that allows you to set meal reminders and track your food intake and activity

Nutrisystem Reviews

The Nutrisystem diet is a popular weight loss program that delivers high-protein, low-calorie, portion-controlled meals and snacks to your door every 2-4 weeks. The company claims you’ll lose up to 7 pounds in your first week. After that, they claim, you’ll see a 1-2 pound drop in your weight per week. Nutrisystem offers several different meal plans to choose from based on your age, gender, health conditions, and more.

Nutrisystem is a popular weight loss program that’s been around since the 1970s. The premise of the diet is simple: Eat six small meals per day to help prevent hunger — theoretically making it easier to lose weight. By limiting the calories in your meals, you can lose weight via calorie restriction. To make the calorie restriction process easier, Nutrisystem provides several of your meals for you. These meals are either frozen or shelf-stable, but fully cooked and only require reheating. Nutrisystem also provides shakes that you can use for snacks. Example meals include:

• Breakfast: multigrain cereal with skim milk, banana

• Snack 1: protein shake made with skim milk

• Lunch: turkey and cheese sandwich on whole wheat bread

• Snack 2: whole grain crackers and cheese

• Dinner: baked salmon, brown rice, salad with vinaigrette dressing

• Snack 3: 2–4 squares of dark chocolate

Nutrisystem is a diet program that provides premade meals and snacks to help make it easier to lose weight through a calorie deficit. And for those who are concerned that they’ll put the weight back on once they’ve canceled the meal delivery service, Nutrisystem has them covered: Nutrisystem provides the guidance needed to implement healthy and sustainable habits for life. They also offer transition and maintenance plans for those who’d like to continue receiving meals, snacks or even just Nutrisystem protein shakes as they navigate life after Nutrisystem.

Nutrisystem with a balanced meal plan designed by nutrition experts and backed by science, a tasty menu that proves that any food can be “diet food,” on-demand support from weight loss coaches and a useful companion app, plus help sustaining weight loss results.

How Does Nutrisystem Work?

Nutrisystem is a 4-week program. However, you can repeat the 4-week program as many times as you like. On Nutrisystem, you should aim to eat six small meals per day, including breakfast, lunch, dinner, and three snacks. Several of these will be frozen meals or shakes that are provided by Nutrisystem and designed to be nutritionally balanced, providing a combination of fiber, protein, and fats.

Week 1 is a bit different from the remainder of the program. During this week, you eat 3 meals, 1 snack, and 1 specially formulated Nutrisystem shake per day. According to the company, this regimen supposedly prepares your body for weight loss success.

However, during the remaining 3 weeks, you should aim to eat six times per day. For meals and snacks that are not provided by Nutrisystem, the company recommends choosing lean, low calorie, and low sodium options.

Each week, you’re also allowed a total of up to eight “Flex Meals” — 2 breakfasts, 2 lunches, 2 dinners, and 2 snacks — to account for meals that may not be ideal for weight loss but may be part of a holiday or special occasion.

You can also use the free NuMi app provided by Nutrisystem for meal planning guidance. The NuMi app, which is available on both Google Play and the Apple App Store, offers several unique features, including:

• tracking for both Nutrisystem meals and regular foods

• weight logs to monitor your progress

• daily reminders for water intake, exercise, and meal logging

• free resources, including recipes, tips, and informational articles

• challenges, contests, and special offers from Nutrisystem

• Specialized programs

Overall, Nutrisystem is a 4-week, low calorie, nutritionally balanced diet program. There are special menu options for women, men, people with diabetes, and people following a vegetarian diet.

Menu Variety of Nutrisystem

Nutrisystem’s menu features a combination of frozen meals and microwave- or oven-ready foods for breakfast, lunch, dinner, and snacks. Nutrisystem separates its meals into 2 main categories (for men and for women) in order to provide you with options that fit your caloric and nutritional needs.

There are also Nutrisystem plans that contain 5 or 7 meals per day along with snacks. You can also opt to add additional meals (Hearty Inspirations) to your plan as well as protein shakes.

Just like WonderSlim, Nutrisystem recommends eating around 3 to 4 meals per day. However, unlike WonderSlim, you’ll receive ready-made meals that are either frozen or ready to pop in the oven or microwave.

Nutrisystem offers fully prepared meals that are portioned for weight loss. Each meal combines healthy fats, lean protein, and smart carbs to create a delicious and tasty menu. Plus, you get to try a variety of cuisines, from good old American to Mediterranean, Asian, and more.

Can I Custom My Own Meal?

Nutrisystem doesn't allow you to add or remove ingredients from existing meals, but you have complete freedom to choose your own meals. Nutrisystem only offers monthly deliveries, so you have to build your plan for the entire month (which is a bit tedious and time-consuming). However, Nutrisystem lets you choose if you want to leave menu building in the hands of the specialists (Chef’s Choice) or if you want to be in full control and choose your own meals. Plus, Nutrisystem has an entire collection of shakes specially designed to support weight loss. These aren’t included in the main meal plans and come as an extra.

Nutrisystem has options for a wide range of dietary needs such as vegetarian, diabetes-friendly, keto, paleo, low-sodium, and so on. However, the only one that offers a comprehensive filtering system while choosing your meals is Nutrisystem. Nutrisystem menu can be filtered pretty extensively. You can get options for high-protein, low-carb, keto-friendly, low-fat, bariatric, kosher, lactose-free, and tons more.

Lastly, in terms of allergies, Nutrisystem doesn't cater to any, specifically. If you have mild allergies, or simply prefer to avoid certain ingredients, make sure to read the menu labels carefully. If you have severe, life-threatening allergies, it’s best to avoid both services entirely.

Nutrisystem Plans & Prices 

Nutrisystem offers women's, men's and Partners’ diet plans, which start at $8.80 per day. Prices vary depending on which plan you choose, what extras you add to your order, and whether you pay for 2 or more monthly auto-delivery orders in advance. You have the option to order plans for either 5- or 7-days which also impacts your total cost.

If you don’t want to sign up for a structured plan, Nutrisystem Advantage is a more flexible option. You can subscribe for either 6 or 12 months and order whatever you want from the full Nutrisystem menu. Costs work out at around $8 per month. As well as ordering when you want, you can set up auto-deliveries, get discounts on meals, and still get access to personalized coaching.

Shipping is free if you prepay for 2 or more shipments of a structured plan. One-time plan orders start at $9.99 per shipment. For Advantage, shipping is free on orders of either non-frozen items, or over $99 of frozen products. Orders that don’t meet the threshold cost $20 for shipping.

WeightWatchers Reviews

Established in the early 1960s by business entrepreneur Jean Nidetch, WW is a weight loss program that caters to would-be dieters seeking a sustainable lifestyle change who don’t necessarily want to lose a lot of weight fast. The program rebranded to WW from Weight Watchers in 2018.

WeightWatchers focuses on lasting weight loss through behavior change, nutrition science and social support. This includes taking a holistic approach to help members develop sustainable habits, eat healthier and move more. WW offers support via its app, virtual and in-person workshops and advice about changing your food-related behaviors and attitude.

The premise of the program is simple: Based on your starting weight, how many pounds you want to lose and your typical food preferences, you receive a set amount of points you’re allowed to consume daily. The amount of points increases if you exercise. Each food represents a number of points—foods with high levels of sugar and saturated fat have higher point values. You can then use the accompanying WW app to figure out the point values of your meals and account for your daily points. The WW app is free with a membership. It allows you to do all of the following:

• Track food intake using points.

• Track weight, activity, and sleep.

• Access a collection of more than 12,000 recipes.

• Use the Restaurant feature to find the point value of foods from your favorite places.

• Join online groups of WW members. Much like other forms of social media, you can post comments, read and react to others’ comments, and share photos. 

• Listen to audio sessions and read articles about healthy eating habits and stress management, with meditations and music from Breethe.

• Find virtual and in-person workshops (available only for premium members).

• Shop for WW products, including cookbooks, meal planners, scales, and food.

How Does WeightWatchers Work?

WeightWatchers helps members lose weight and keep it off by changing their relationship to food. While no food is off the table, WW takes into account a food’s nutritional factors – like added sugars, fiber, protein and saturated fats vs. unsaturated fats – to create a single number: the Points value.

WW bases its Points system on the belief that all foods can fit into a weight-loss diet as long as you stay within your allotment of Points for the day and week. Similar to other diets, WW takes info such as your age, weight and height into consideration when customizing your Points. Being active can increase your weekly number of Points.

Using the app, you can easily figure out the number of Points in each food you eat and keep track of how many Points you have remaining for the day. The company offers thousands of recipes, each with a Points value, and you can find the point values for more than 355,000 foods on the mobile app.

If you eat three pieces of pizza and a regular soda, you will almost certainly be out of Points for the day. This means for the rest of the day, you'll need to choose low or ZeroPoint foods, such as non-starchy vegetables. And that’s the goal of the point system – to easily track the foods you eat so you can stay within your limits. With WW's list of more than 200 ZeroPoint foods, you won't be going hungry. Included on the list are:

• Fruit.

• Non-starchy vegetables.

• Beans.

• Poultry. 

• Eggs. 

• Popcorn.

• Fat-free yogurt.

Overall, no foods are off limits: You can eat whatever you want – provided you stick to your Points budget. In addition, every WW member receives access to thousands of recipes, a weight and activity tracker and access to a members-only online forum. Premium members also have access to live coaching via in-person workshops (if available in your area) and virtual workshops. Core or premium members do not have a fixed membership period and can continue the program after reaching their goal weight.

Menu Variety of WeightWatchers

No food is off-limits: You can eat anything as long as you stay within your daily points budget. You also get a certain number of weekly points to use whenever you want. So if you go to a birthday party, for instance, and eat a piece of cake that puts you five points over your daily budget, you can use five of your weekly points. It’s a nice way of learning that it’s what you eat over time, not every single day, that matters.

Over 200 foods are ZeroPoints foods, which means they don’t take up any of your daily points and don’t need to be tracked. Non-starchy vegetables, certain fruits, dairy products like fat-free yogurt and cottage cheese, poultry, fish and shellfish, tofu and tempeh, eggs, and legumes like beans, peas, and lentils are all ZeroPoint foods. According to WW, you can eat as many of those foods as you want and still lose weight.

Can I Custom My Own Meal?

Yes! You can eat everything what you want. No food is off-limits: You can eat anything as long as you stay within your daily points budget.

Verdict: Which One is Best for You?

These four companies have different weight loss plans, and which one you choose depends on your own habits.

• WonderSlim is a typical meal replacement diet where the majority of meals and snacks are replaced by packaged diet foods. This approach is often successful for weight loss because it makes portion control easy. However, the meal replacements are highly processed and contain many unhealthful ingredients. Additionally most dieters tend to regain weight on these types of programs once a normal diet is resumed.

• The Optavia diet promotes weight loss via low calorie packaged foods, low carb homemade meals, and one-on-one coaching. While the initial 5&1 Plan is fairly restrictive, the 3&3 maintenance phase allows for a greater variety of foods and fewer processed snacks, which may make weight loss and long-term adherence easier. However, the diet is expensive and repetitive and doesn’t accommodate all dietary needs. What’s more, extended calorie restriction may result in nutrient deficiencies and other potential health concerns. While the program promotes short-term weight loss and fat loss, there are better alternatives to consider for maintaining a healthy weight in the long run.

• With perfectly portioned, fully prepared meals and snacks delivered directly to your door, Nutrisystem has taken the work out of weight loss. Unlike many other diet plans, the Nutrisystem program is designed by expert dietitians and backed by science—you won’t find any gimmicks here. And, by keeping healthier versions of typical “no-no foods” on the menu, Nutrisystem has taken the restrictive part of dieting off the table. Not only that, Nutrisystem’s diet plans won’t leave you hungry, weak or feeling deprived like so many others, since members eat six times a day, and can have as many veggies as they’d like. Nutrisystem helps customers learn and practice healthy habits to help sustain their weight loss long after they stop their meal delivery. And with a variety of transition and maintenance plans available for those concerned they’ll put the weight back on once they stop their food shipments, there’s really nothing they haven’t thought of.

• WeightWatchers is a popular weight loss program that attracts hundreds of thousands of new members every year. Its flexible, points-based system appeals to many people and encourages an overall balanced lifestyle. Plus, studies have found that WeightWatchers is an effective way to lose weight and keep it off. While it’s not right for everyone, WeightWatchers is an evidence-based weight loss program that is worth considering to help you meet your health and wellness goals. But WeightWatchers doesn’t guarantee a balanced diet. To maintain a balanced diet, you need to take the time to set up your own recipes.
