Frequently Asked Questions
What is the difference between your Meal Plans?
Our dietitian-reviewed plans support healthy, long-term weight loss. They combine portion and calorie-controlled meals with self-prepared balanced dinners that include all food groups. You'll eat every 2-3 hours to help stabilize blood sugar, reduce cravings and continue burning calories.
Our plans also include healthy grocery additions like fruits, vegetables, and other nutrient-rich foods for you to prepare your balanced dinners. This helps build lasting habits around portion control, smart shopping, and meal planning.
Basic Plan: Includes 4 portion-controlled products per day. You’ll prepare both lunch and dinner yourself, allowing for more flexibility with your own healthy meals.
Core Plan: You’ll receive 5 portion-controlled products each day and just need to prepare your own healthy dinner, along with some healthy sides throughout your day.
Premium Plan: Provides 7 portion-controlled products each day for maximum convenience. Your only prep is a healthy dinner, plus a few fruits and veggies as daytime additions.

Our goal is to keep your taste buds excited and engaged every step of the way.
Are the diet kits customizable?
Absolutely! Our 4-Week Diet Kits are fully customizable to suit your tastes, preferences, or dietary needs. Customizing your diet kit is quick and easy right on our website, or if you’d like some extra help making your selections, our friendly Customer Service team is always happy to assist you by phone, email, or live chat.
Why aren't the Meal Replacement Bars part of the diet kit?
Our Meal Replacement Bars are a fantastic option packed with 15g of protein to help keep you satisfied. However, they do have a slightly higher carb and calorie count compared to other meal replacements in our kits. Because of this, they’re designed more for maintenance and long-term support once you’ve completed your initial diet kit. Think of them as a great way to stay on track and nourish your body after you’ve reached your goals!
Can I use Wonderslim if I have a medical condition?
We recommend consulting your healthcare provider before starting any weight loss plan, especially if you have a medical condition or take medication.
Will this be a recurring subscription?
Our diet kits are not set up as a recurring subscription at this time. You have full control to order your kit whenever you’re ready, allowing you to choose what works best for your schedule and goals. Plus, by customizing a diet kit, you can save up to 30% off a la carte prices, making it even easier to stay on track. Feel free to come back and reorder whenever you need to keep making progress. We’ll be here to support you every step of the way!
Is there a money-back guarantee?
Yes! We offer a 30-day satisfaction guarantee. If you're not happy with your purchase, contact us and we’ll guide you through the return process.
Do you weigh your protein raw or cooked?
We recommend weighing your protein after it’s cooked using a digital food scale. This way, you’ll get the most accurate portion size and make it easier to track your meals and stay on target with your plan. Cooking can change the weight due to moisture loss, so weighing cooked protein gives you a more consistent serving every time.
Am I allowed to drink alcohol while following the Wonderslim Plans?
Alcohol is not recommended on the plan. It adds extra calories with little nutritional value, can slow weight loss progress, and often stimulates the appetite. Alcohol can also contribute to dehydration, making it harder for your body to stay balanced and energized.
What if I have to dine at a restaurant?
Dining out can still align with your plan. Choose lean proteins, steamed vegetables, and avoid sauces or fried foods. Many restaurants can accommodate dietary needs—don’t hesitate to ask!
Do your kits include coaching/support?
While we don’t have one-on-one coaching, our dedicated Customer Care team has personal experience with our meal plans and is always happy to help. Whether you have questions, need guidance, or just want a little encouragement along the way, we’re here to support you every step of your wellness path.
How much weight will I lose?
Weight loss varies by individual and depends on factors like metabolism, body composition, and lifestyle
- Protein-Smart Plans: Most people lose around 1–2 pounds per week
- Keto Plans: Results vary; calorie levels can be adjusted to maintain steady progress.
- GLP-1 Plans: Outcomes depend on your body and medication. Consult your doctor if weight loss feels too fast or stalls.
No matter the plan, focus on how you feel, not just the scale.
Is Wonderslim suitable for people with dietary restrictions?
Many of our products are vegetarian, gluten-free, or lactose-free. Be sure to check labels or contact us directly for any specific dietary concerns.
Do I have to exercise on these plans?
Exercise is not required, but it’s definitely encouraged as part of a healthy lifestyle. Adding regular activity to your plan can support your progress and help you feel your best. Just be sure to tailor the intensity to your personal fitness level and goals. Whether it’s a daily walk, yoga, or strength training, find what feels good for you and enjoy the extra boost it brings to your journey!
Can I skip a meal if I am not hungry?
It’s important not to skip any meals when following our plans, even if you’re not feeling hungry at the moment. Consistency is key to supporting your body with the balanced calories and protein it needs throughout the day. Sticking to regular eating times also helps keep your energy steady and can prevent that “extra hungry” feeling from sneaking up on you later. Treat each meal as part of your plan to fuel your body and stay on track with your goals!
What if I am hungry between meals?
If you’re feeling hungry between meals, we recommend having an additional meal shake. This will help keep your energy up, support your protein goals, and make sure you stay on track throughout the day.
Are Wonderslim kits designed to meet the nutrition needs of GLP-1 users?
Yes, Wonderslim diet kits provide the right nutrition for someone taking a GLP-1 medication. They are built around high-protein meal replacements, which can be especially beneficial for those using GLP-1 medications. According to Dr. Sue Shapses of Rutgers University, meal replacements are an excellent option to help supplement the common lack of sufficient protein and essential nutrients that most GLP-1 patients face. Dr. Holly Lofton of New York University further notes that using high-protein meal replacements alongside GLP-1 therapy can help reduce the loss of lean body mass, which was observed at 9.7% in clinical evaluations of patients in the STEP 1 Study.[4]
If I’m already on a GLP-1 medication, do I still need a diet plan?
Yes. Research shows that GLP-1 use can lead to a 20–50% loss of muscle mass[3], making adequate daily protein essential to preserve lean muscle while losing fat. Wonderslim Diet Kits provide perfectly portioned, high-quality protein and balanced nutrition to support fat loss and help maintain lean body mass, whether used alongside or instead of GLP-1 medications.
