Scary Spice Mel B. bids bye-bye to baby weight after passing her halfway mark to her goal and losing eight kilos after two months of Jenny Craig Program. But can dear, reliable Jenny really help those who are overweight or obese in eating off some pounds?

According to Mel B., a month after giving birth to her third daughter Madison, she turned to Jenny to shed off the baby bump weight and get her pre-baby body back. Having committed to lose a total of 15 kilos, she has already lost eight kilos.

But with different celebrities and people testifying, in addition to the movies referencing on the benefits of following Jenny, some are still left wondering if she could really help those who have weight problems lose weight with well-portioned frozen foods, or will it leave them with a bitter taste in their mouths?

Jenny's program essentially has three levels to help people lose weight and keep it off. The first level teaching clients how to eat foods they want in small portions, the second one showing their clients how to increase their energy through simple activities, and the third revolves around building a more balanced life with a healthy diet.

Serving prepackaged, frozen meals for breakfast, lunch, dinner, and dessert, each one contains 50% to 60% carbohydrates, 20% to 25% protein, and 20% to 25% fat each. In the plan, clients are also encouraged to supplement their meals with fresh fruits and vegetables, whole grains, and reduced-fat dairy products.

However, with the charms that Jenny has along with the allure of the delicious meals, some experts have their doubts on how people will maintain their lost weight or lose weight to begin with.

In an interview with WebMD, Leslie Bonci, MPH, RD, director of sports nutrition at the University of Pittsburgh Medical Center, said that though Jenny teaches portion control the problem is when people get off the packaged meals as it is hard to control portion and count calories in a normal setting. Bonci noted that what should be done instead is to help people go back to eating normally.

Adding a sprinkle of reality to the mix, WebMD also taste tested a week's worth of Jenny's foods and found that most of them had comparable taste to that of frozen-food entrees, and just by being frozen already eliminates other people's taste buds.

And if the frozen foods are found to be of the taste of the person, a study done back in November 2008 discovered that obese people expressed their disdain as to the length of time they needed to stay on the program to lose a significant amount of weight, Livestrong.com reported.

Another issue that clients found to be distasteful is the cost in staying in the program. In a series done by the TODAY show called "TODAY Investigates Diet Programs," Lisa Abbott, a mom of twins that was on a Jenny program for three months spent about $1,735 - roughly $578 a month, and that doesn't include the food supplements like fresh fruit and vegetables. In addition to this, Abbott said that it's hard to start since the portions are so small.

With that said, TODAY show advised only those who have a busy schedule, who doesn't want to cook, or those who don't want to count points or food groups to avail of Jenny's program. On the other hand, the program was not allowed to those who eat out often, those who like to cook, who have a complicated medical history, and those who don't like pre-packaged meals.
