Overweight and obesity are defined as abnormal or excessive fat accumulation that presents a risk to health. Obesity is the most commonly caused by a combination of excessive food intake, lack of physical activity, and genetic susceptibility. Diet plays an important role in the genesis of obesity. Most people will need to reduce their daily kilojoule intake in order to lose their weight. This means eating and drinking less and making healthier food choices in their daily life.
As societies become increasingly reliant on energy-dense fast-food meals, the association between fast food consumption and obesity becomes more connecting. Consumption of sweetened drinks is also believed to be a major problem to the rising rates of obesity. Meat consumption is positively associated with weight gain.
Existing evidence from large-scale cross-sectional and prospective cohort studies supports that consumption of sugar-sweetened beverages is correlated with the childhood and adult obesity. Sweetened drinks containing either sucrose or in combination with fructose appear to lead to weight gain due to increase energy intake.
The widespread availability of nutritional guidelines has done little to address the problems of overeating and poor dietary choice.
Most of this extra food energy came from an increase in carbohydrate consumption rather than fat consumption. The primary sources of these extra carbohydrates are sweetened beverages, Consumption of sweetened drinks such as soft drinks, fruit drinks, iced tea, and energy and vitamin water drinks is believed to be contributing to the rising rates of obesity now-a-days.
Calories consumed have increased among many people due to increased consumption of energy-dense foods, which tend to be high in fat and sugar.
The treatment for obesity mainly depends on diet intake and physical exercise. Diet programs may produce weight loss over the short term, but maintaining this weight loss is frequently difficult and often requires making exercise and a lower calorie food energy diet should be a permanent part of a person’s lifestyle.
