Energy Utilisation in Human Metabolism
One small chocolate chip cookie (50 calories) is equivalent to walking briskly for 10 minutes.
The difference between a 80%
large gourmet chocolate chip cookie and a small chocolate chip cookie could be
70%
about 40 minutes of raking leaves (200 calories).

One hour of walking at a moderate
pace (20 min/mile) uses about the same amount of energy that is in one

Impact of Obesity on GP Consultations

BMI
• Low BMI was associated with fewer physical health problems than mid-level or higher BMI.
• Indicators of health care use showed a J-shaped relationship with BMI for general practitioners (>5 GP
Consultations).
• Prevalence of medical problems (for example, hypertension OR 6x and diabetes OR 6x), surgical procedures
(cholecystectomy OR 7x and hysterectomy OR 2x) and symptoms (for example, back pain OR 40% and
constant tiredness OR 70%) increased monotonically with BMI.
Effect of Diet and Surgery on Weight & Mortality
•Diet & exercise effective up to 6m
•60% failure at 1 yr.
•80% failure at 2 yrs.
•100% failure at 5 yrs.
•Surgery effective long-term (80%)

Take Home Message
Bariatric surgery is a cost-effective treatment for
obesity which leads to resolution of co-morbidities,
improved quality of life and increased life expectancy
However, patients need lifelong follow-up after surgery
in order to avoid harm – this can be performed by their
surgical team and by the primary care.
Patients can present with nausea, vomiting, dysphagia,
reflux, abdominal pain and neurological symptoms.
Common things are common!
Nutritional deficiencies are common and easily
preventable.
Thank you!
