Dr Michael Spira (born 24 April 1944) is a British medical doctor and GP with a special interest in weight management.
Spira was educated at Stowe School, Buckingham. After training at St Bartholomew's Hospital, London, he entered general practice and became a senior partner in a large NHS general practice. He was also a visiting physician at Bupa Wellness, London. He was a member of the Counterweight Project, the government-funded multi-centre obesity programme to evaluate the management of obesity in primary care, and of the Scottish Intercollegiate Guidelines Network Working Party on Obesity. He is a member of the National Obesity Forum. He has been adviser to several leading slimming organisations and publications and has appeared on many national radio and TV programmes, such Kilroy and ITV's Good Morning. He has had various white papers published on a variety of topics, including weight management. [1] He has a particular interest in the role of HIIT (high intensity interval training) in weight control. Currently he is medical director of the Smart Clinics which provide integrated healthcare in South Kensington, Notting Hill and Wandsworth [2]
Dieting is the practice of eating food in a regulated way to decrease, maintain, or increase body weight, or to prevent and treat diseases such as diabetes and obesity. As weight loss depends on calorie intake, different kinds of calorie-reduced diets, such as those emphasising particular macronutrients, have been shown to be no more effective than one another. As weight regain is common, diet success is best predicted by long-term adherence. Regardless, the outcome of a diet can vary widely depending on the individual.
The fat acceptance movement, also known as fat pride, fat empowerment, and fat activism, is a social movement which seeks to eliminate the social stigma of obesity from social attitudes by pointing out the obstacles which are faced by fat people to those who are less fat. Areas of contention include the aesthetic, legal, and medical approaches to fat people.
Obesity is a medical condition, sometimes considered a disease, in which excess body fat has accumulated to such an extent that it may negatively affect health. People are classified as obese when their body mass index (BMI)—a person's weight divided by the square of the person's height—is over 30 kg/m2; the range 25–30 kg/m2 is defined as overweight. Some East Asian countries use lower values to calculate obesity. Obesity is a major cause of disability and is correlated with various diseases and conditions, particularly cardiovascular diseases, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis.
Fasting is the abstention from eating and sometimes drinking. From a purely physiological context, "fasting" may refer to the metabolic status of a person who has not eaten overnight, or to the metabolic state achieved after complete digestion and absorption of a meal. Metabolic changes in the fasting state begin after absorption of a meal.
Weight loss, in the context of medicine, health, or physical fitness, refers to a reduction of the total body mass, by a mean loss of fluid, body fat, or lean mass. Weight loss can either occur unintentionally because of malnourishment or an underlying disease, or from a conscious effort to improve an actual or perceived overweight or obese state. "Unexplained" weight loss that is not caused by reduction in calorific intake or exercise is called cachexia and may be a symptom of a serious medical condition.
A fad diet is a diet that becomes popular for a short time, similar to fads in fashion, without being a standard dietary recommendation, and often making pseudoscientific or unreasonable claims for fast weight loss or health improvements. Fad diets are not supported by clinical research and their health recommendations are not peer-reviewed, thus they often make unsubstantiated statements about health and disease.
Bariatrics is the branch of medicine that deals with the causes, prevention, and treatment of obesity.
General fitness training works towards broad goals of overall health and well-being, rather than narrow goals of sport competition, larger muscles or concerns over appearance. A regular moderate workout regimen and healthy diet can improve general appearance markers of good health such as muscle tone, healthy skin, hair and nails, while preventing age or lifestyle-related reductions in health and the series of heart and organ failures that accompany inactivity and poor diet.
A very-low-calorie diet (VLCD), also known as semistarvation diet and crash diet, is a type of diet with very or extremely low daily food energy consumption. VLCDs are defined as a diet of 800 kilocalories (3,300 kJ) per day or less. Modern medically supervised VLCDs use total meal replacements, with regulated formulations in Europe and Canada which contain the recommended daily requirements for vitamins, minerals, trace elements, fatty acids, protein and electrolyte balance. Carbohydrates may be entirely absent, or substituted for a portion of the protein; this choice has important metabolic effects. Medically supervised VLCDs have specific therapeutic applications for rapid weight loss, such as in morbid obesity or before a bariatric surgery, using formulated, nutritionally complete liquid meals containing 800 kilocalories or less per day for a maximum of 12 weeks.
Health at Every Size (HAES) is an approach to public health that seeks to de-emphasise weight loss as a health goal, and reduce stigma towards people who are overweight or obese. Proponents argue that traditional interventions focused on weight loss, such as dieting, do not reliably produce positive health outcomes, and that health is a result of lifestyle behaviors that can be performed independently of body weight. However, many criticize the approach and argue that weight loss should sometimes be an explicit goal of healthcare interventions, because of the negative health outcomes associated with obesity.
Health is the state of complete physical, mental, and social well-being and a positive concept emphasizing social and personal resources, as well as physical capacities. This article lists major topics related to personal health.
Intermittent fasting is any of various meal timing schedules that cycle between voluntary fasting and non-fasting over a given period. Methods of intermittent fasting include alternate-day fasting, periodic fasting, and daily time-restricted feeding.

He is perhaps best known for diagnosing David Letterman's heart condition in 2000. His book, released in 2009, The Skinny on Losing Weight Without Being Hungry is a NY Times best-seller. His book, The Change Your Biology Diet: The Proven Program for Lifelong Weight Loss with a foreword by David Letterman was published on January 5, 2016.
Michael Mosley is a British television journalist, producer, presenter, and former doctor who has worked for the BBC since 1985. He is probably best known as a presenter of television programmes on biology and medicine and his regular appearances on The One Show. Mosley is an intermittent fasting and low-carbohydrate diet advocate who has written books promoting the ketogenic diet.
Weight management refers to behaviors, techniques, and physiological processes that contribute to a person's ability to attain and maintain a healthy weight. Most weight management techniques encompass long-term lifestyle strategies that promote healthy eating and daily physical activity. Moreover, weight management involves developing meaningful ways to track weight over time and to identify ideal body weights for different individuals.
Management of obesity can include lifestyle changes, medications, or surgery. Although many studies have sought effective interventions, there is currently no evidence-based, well-defined, and efficient intervention to prevent obesity.
