Yes, it's not a very flattering photograph. When you get old they rarely are!
I've been a Cambridge consultant on and off for 40 years. I'm now well past 70 but still fit & healthy. Over many years I've helped at least 4000 people lose weight. Often very substantial weight. I've been very successful with clients who have been diagnosed with type two diabetes. Clients who have a Body Mass Index of more than 40 are particularly welcome to contact me. Over the years I have developed considerable understanding of the challenges these clients may face and how to move forward to a more acceptable lifestyle. I am well aware of the occasional need for considerable confidentiality and acceptance. 
With slimmer ( and younger?) clientele who want rapid weight loss very quickly I'm prepared to offer "special deals".

Although I am based in Derby I'm happy to travel considerable distances to clients who may live in more isolated places and/or find public transport challenging. Such contacts  carry initially zero exstra costs. (Free!)

 Phone me. Email me. Text me. Things get better by appropriate action. For the more mature readers of my profile I quote Karl Marx ."You have nothing to lose, but your weight !"
