Obesity Excess Body

Obesity is characterized by a ratio greater than 29.9 of body mass in kilograms divided by height in meters squared. The mass is adipose tissue as an inert depot for excess energy has shifted. Adipose tissue is recognized as a dynamic organ and play important roles. Obesity exhibit increased marker of inflammation such as macrophage infiltration, C-reactive protein and tissue factor. Obesity is associated with type 2 diabetes, cardiovascular disease, hypertension, stroke, sepsis, impaired wound healing, asthma, inflammatory bowel disease.

The more fat is eaten than is burned in the body, the more excess will be stored and gain weight. Body weight is influenced by amount of fat and carbohydrate. A high fat diet leads to obesity more easily than a low fat diet. Food intake is initiated by a variety of factor such as availability of food, internal hunger drivers, lead to food seeking.

This phenomenon of sensory- specific satiety related to different foods is an important item in short-term regulation of the amount humans eat. The decelerating rate of food intake implies an initial stimulation to food intake produced by the smell,
