Successful in the Short-Term
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.
