With more than 640 centers around the globe and thousands of female followers, Jenny Craig has established itself as a leader in the weight-loss industry since 1983.

The Jenny Craig approach is built on three tenets: food, body and mind. The food element focuses on healthy eating and portion control and also teaches you how to eat the foods you love in moderation, and the body element focuses on exercise, overcoming barriers and being physically active. The mind element focuses on positive thinking and getting the support you need to reach your weight loss goals.

The program is best known for its prepackaged and portion-controlled meals. But Jenny Craig sets itself apart from other meal-delivery diets because as you reach your goal weight, you work closely with Jenny Craig counselors to learn about portion control and healthy cooking at home or while dining out.

After an in-depth interview with a Jenny Craig representative, you are given a personalized meal and fitness plan. The two basic programs are the In-Person Support and Jenny Direct programs. With the former, you attend weekly meetings, consultations and food pick-up at your local Jenny Craig center, and the latter gives the same support over the phone and delivers food to your door.
