A majority of Americans are overweight; in fact the United States is now the fattest country in the world, according to the World Health Organization. The continued prosperity of the U.S. is partially contingent upon our citizens becoming lean, as the health implications with their associated costs are enormous!

Two major factors contribute to obesity: (1) lack of exercise and (2) the quality and closely-linked quantity of food intake. The result of (1) not exercising is relatively straightforward, and the benefits of engaging in quality physical activity are discussed at the Exercise webpage. Similarly, (2) our dietary decisions lead to excess body fat directly and indirectly.

Direct Cause of Excess Body Fat—Foods high in fat are normally considered the culprit cause of excess body fat. While fats, especially animal fats, are normally unhealthy, there is an even larger villian. Highly glycemic (bad) carbohydrates causes blood sugar levels to rise above normal, which results in increased insulin levels. Weight gain, among other negative effects, results. Highly glycemic foods also increase our appetite, and may also cause an increase in fat by increasing triglycerides.

Indirect Cause of Excess Body Fat—In general, foods that are devoid of life-giving nutrients cause our bodies to cry out for necessary nutrients, which results in further hunger. As we continue to eat to satisfy the craving, our weight increases while our health decreases.
