WonderSlim is a delicious, simple, effective and affordable weight loss plan. It is nutritious, being designed by registered nutritionists and dietitians. You can customize the plan so you get foods that you actually love. There is no subscription required and you can order how and when you want.

How does WonderSlim work?

WonderSlim focuses on meal replacement. This means that the more unhealthy, unbalanced, over-sized meals you replace with a WonderSlim meal, the more weight you’ll likely lose.

To ensure that your metabolism will be running at its peak efficiency, you’ll have a meal every 2 to 3 hours.

What plans does WonderSlim offer?

WonderSlim offers three plans. The Basic Essentials is a 4-week plan that includes 4 meals a day and has all that you need to get started. The Core Classic contains 5 meals every day for 4 weeks and offers increased portion control. The Premium Complete includes 7 meals per day. Also good for four weeks, it is WonderSlim’s most complete plan.

Can a new mom go through the WonderSlim diet plan?

It is ideal for new mothers to wait for 6 to 8 weeks after they have given birth before attempting any active weight loss to allow the body to establish enough milk supply as well as to let it recover from childbirth. Before starting a weight loss program, WonderSlim advises new moms to first refer to their doctors for proper guidance.

Does WonderSlim ship internationally?

Yes. WonderSlim currently ships to a select number of countries with two shipping options. FedEx International Priority has an estimated delivery time of 1-3 business days. FedEx International Economy may take 3-5 business days for delivery. However, this largely depends on the destination and does not include possible customs delays.
