Commitment to quality – for 25 years
Slim·Fast understands that weight loss is about losing the weight and keeping it off.
We know that weight loss is a state of mind as much as it is a physical state. That is why we are committed to helping our dieters achieve their goals in a nutritious and healthy manner.
We are dedicated to helping you succeed in losing weight and keeping it off – for years not months. In late 2004, we introduced the new Slim·Fast Optima Diet; a remarkable new approach based on having a healthy personal goal for weight loss, rather than trying to achieve an impossible "perfect" goal. We understand that dieting is not about being a perfect size 4 or 6 – some of us look and feel terrific in a 10 or 12. The Slim·Fast Optima Diet believes one size does not fit all. Your diet must be customized to meet your specific needs.
We believe achieving healthy weight loss is really all about calorie reduction. In order to burn fat, you must eat less and move more. In other words, calories in need to be less than calories out. We know that it is almost impossible to succeed when you're cutting calories on your own. It is often very complicated and can leave you feeling starved.
That's why Slim·Fast Optima makes calorie reduction more manageable so real weight loss success can be within reach. Our Optima products feature harder-working calories, which in contrast to regular "empty" calories, provide a precise nutritional balance of lean proteins, complex carbohydrates and healthy fat blends.

Every calorie works harder to keep you satisfied. In addition to our new line of delicious products, the Optima Diet also lets you enjoy more of your favorite foods, making the plan easier to stick to.
With Slim·Fast, there is always someone to talk to if you need help. Free, personalized professional advice from our registered dietitians and support is available to you 24/7. We also provide self-monitoring tracking tools to help you track your success.
