The Jenny Craig weight loss program is a bit more traditional and simple in my opinion, though it probably costs a bit too much for the average person (it's also a little too basic in its principles, in our opinion).
This entire diet seems to be based on eating fewer calories while exercising more, which is a very old concept. With Jenny Craig you get assigned your own weight loss expert (nutrition counselor) who will help to keep you motivated each week so that you'll remain on the diet.
This is possible because Jenny Craig has many weight loss centers throughout the world, and if dieters live close to a facility then they can choose to meet with a nutrition consultant "in person". Or, if dieters do not live near a facility then they can choose to meet with their nutrition counselor "via telephone" each week.
...But regardless of whether you meet with your nutrition consultant via telephone or in person -- you'll still have to buy Jenny Craig's expensive "pre-packaged" meals. That's the downside of this diet program in my opinion, since you have to continually buy Jenny's pre-packaged meals (which are fairly expensive when compared to normal meals).
From everything I've seen these pre-packaged meals seem to be lower calorie versions of normal meals, so they don't seem to be anything too earth shattering or special (from our perspective).
So with Jenny Craig you'll basically be eating fewer calories (smaller portioned meals) and exercising more while meeting weekly with a nutrition counselor (who will keep you motivated so that you don't quit the diet).
Plus, don't forget that you'll be required to buy Jenny Craig's pre-packaged food every single week -- which can be expensive over time.
So overall I don't think that it's smart to use the Jenny Craig program, since any diet that requires you to continually spend money for "special meals" is not a good choice in my opinion.
