Online Weight Loss Diet Program Reviews and Costs

The number and type of weight loss programs available online has mushroomed in the last year or so. Weight loss sites offer everything from the latest exciting fad diet to the more down to earth (and arguably more effective) healthy eating/lifestyle approach.

Given so many varieties of online weight loss to choose from - how do you go about deciding which program is the best for you? It really comes down to personal preference but there are some easy comparisons to be made with regards to the level of features and customer service that each program offers to consumers.

See our Online Weight Loss Diet Programs Comparison Chart for a quick overview of nine of the most popular UK online programs.

The reviews below give more information about the approach, features and benefits of each weight loss program, along with some comments from users. Hopefully enough to help you make a decision as to which program will be the best and most effective for you.

Some of the programs offer a free trial offer and information about this is given in each review. The score given for each program is based on scoring used for the comparison chart.

Jenny Craig Diets (jennycraig.co.uk) 11/33 - No longer available

The Jenny Craig diet focused on three key aspects: food, body and mind, and you could choose whether to get the whole package, just the food or just the consultation.

Jenny Craig ceased its UK operation in 2013

If you chose the full program, you got an advisor who will worked with you to develop a personalised program to reach your goals. Each week, you spoke to them privately over the phone, helping to plan your menu and exercise and to discuss how you were doing. You ordered your meals directly through your coach and received them either monthly or once a fortnight. Your personal program also included activities tailored to suit your current level of fitness.

If you chose just the food option, then you just got the meals- there was no personal advisor allocated to you. If you just chose the consultation, then you did not receive the food.
