   The coconut is common in the Pacific Islands, through their utilization in traditional medicine, it contains medium chain triglycerides which help clear blockages of the arteries and increase the rate of metabolism which fight against obesity These fatty acids also have antioxidant properties, for this reason we are interested in the oil of this plant, to know their blessing to the complication of obesity. The present study was designed to compare the effects of diets rich in fat (F) supplemented with coconut oil (CO) compared to other diets supplemented with sunflower oil (SO) (control) on lipid profiles and weight change in rats wistar.
    For this purpose, male rats of Wistar strain weighing 80 ± 5g and are divided into three lots. Rats receiving different diets (D) food for 2 months [D1: 16 ℅ casein + 8 ℅ (SO)], [D2: 16 ℅ casein + 32 ℅ ‘SO)], [D3: 16 ℅ casein + 28 ℅ (SO). + 8 ℅ (CO)], The weights of the rats and the amount of food ingested are taken daily, after 2 months of  diets rats are desiccated and blood collected determination of different lipids parameter in plasma by enzymatic kit.
    The results show a decrease in blood sugar, cholesterol and triglyceride in rats fed with diets of coconut oil compared with rats (controls) consumed diets based on sunflower oil; also coconut oil causes a slowdown in weight change
   Colocynth oil represented a resource control and / or protective of obesity such complication, which involves on cellular mechanisms and lipid and carbohydrate metabolism.
