Obesity results from interactive influences of biological, physiological, psycho-social, behavioural and environmental factors. With such a multifactorial aetiology, prevention of weight gain, weight loss and weight maintenance is less than straightforward. Whilst the energy equation (calories consumed = calories expended +/- calories stored as body fat or glycogen) holds true, food choice is highly complex. As such, interventions that only address factors at the individual level, and do not take into account the social and environmental influences mentioned above, are unlikely to be successful.
For example, Medi Weightloss offers obesity management and metabolic syndrome services for adults and adolescents, medical nutrition therapy and counseling, behavioral counseling, fitness recommendations, screening for type 2 diabetes and other conditions. According to the company, prices may also vary by location. They recommend reaching out to your local provider to get an exact price for the service that interests you.
I have been helping clients to loose weight for over ten years now. My success has lead to employment in the film industry across dozens of films and I have also been employed to optimise the body composition of athletes to help improve their athletic performance. The majority of my work however, is with average, everyday people in my clinics in and around London.
