Obesity Has a Long History The Distant Past The Intermediate Past Today
3
Key Messages Our diet has changed dramatically from the Distant Past Humans have gradually conquered the environment over the Intermediate Past Today we have less physical activity; obesity that is subsidized by the farm policies of the government; which at the same time subsidizes research to prevent and treat it.

Venus of Hohle Fels The Venus of Hohle Fels was found in 2008 in a cave in the Swabian region of Germany. It is made from a Mammoth ivory tusk. Radiocarbon dating places its origin 35,000 years ago. It has large breasts abundant abdomen and exaggerated female genitalia. It weighs 33 grams and is 6.0 cm tall Conrad, NJ Nature 2009;459:248

Have You Ever Had a Llama Steak? A young Llama in the higher ANDES mountains at about 12,000 feet. They are grass-fed and their steaks do not have the “melt in your mouth” we are used to from the corn-fed cattle that are fattened up before sending them to market

Conclusions from Paleolithic and Neolithic Periods Obesity appeared early in human history It can develop on any diet Women more often represented as fat Associated with upper social classes Related to abundance of food and less exercise It is increasing in prevalence It can be described in modern terms as a chronic, stigmatized, neurochemical disease

Hippocrates Was the Father of Medicine Hippocrates (460-370 BC) is called the “Father of Medicine.” Born on the Island of Cos. His major achievements were: To separate medicine from philosophy, To give a scientific base for clinical care. To give physicians a high moral inspiration. National Library of Medicine
19
Hippocrates Approach to Diet and Treating Obesity [o]bese people and those desiring to lose weight should perform hard work before food. Meals should be taken after exertion and while still panting from fatigue and with no other refreshment before meals except only wine, diluted and slightly cold.

Santorio “Father of Metabolism” Sitting on His Scale with His Food Santorio, Father of Metabolism, used this scale to measure the effects on his weight of food intake and losses of body fluid. He introduced insensible losses of fluid. Correcting this was the basis for treating disease. Santorio, Ars Medica 1614 Frontespiece from his book

From There to 99.99% Here: Summary Obesity has been present since the Paleolithic times in all cultures & on all diets The agricultural revolution changed 75% of our diet as did the industrial revolution to follow The Four Humors were the basis for treating obesity from the time of Hippocrates into the 19 th century Modern “obesity” begins about 1850 as do modern diets

Glucagon-Like Peptide 1 GLP-1 is the 7-36 amino acid sequence of glucagon It is an incretin that is released from the L- cells of the intestine and enhances insulin release in the presence of glucose It reduces glucagon release from the α- cells It slows gastric emptying It reduces food intake

Obesity Is Here – The Last 0.01%: Summary Obesity results from an imbalance in energy intake and expenditure in genetically susceptible people Obesity spreads from person to person among close contacts Obesity has a major predictor of diabetes Modest weight loss is beneficial and can be achieved by many strategies, including lifestyle changes, diet, exercise, pharmacotherapy surgery Adherence is the major criterion for successful weight loss Unintended consequences of treatment for obesity continue to be a therapeutic problem Many drugs have been tried, but the risk of side- effects has side-lined many.
