A low carb diet, also known as a low carbohydrate diet, is a diet program designed to promote weight loss while restricting the consumption of carbohydrates. The theory behind a low carb diet is that carbohydrates consumption is linked to increased insulin levels and obesity. Some nutritionists have varying opinions regarding the validity and safety of a low carb diet, but others refer to the strong evidence lending truth to the claim that a low carb diet can actually promote weight loss.

A low carb diet specifically consists of eliminating or reducing foods that contain sugar, grains and starches. With each of these products being labeled as carbohydrates, they are replaced with other foods containing increased fat and protein. Many people enjoy vegetables as part of a healthy diet and while they too are classified as carbohydrates, they are believed to be much healthier than grains.

As with most diet programs, there are two sides to the story with individuals who oppose and those who agree with the approach. Specifically, some experts believe that low carb diets carry their own risks and possible side effects, including headaches, fatigue, nausea, dizziness and/or dehydration. By lowering or eliminating dietary fiber, many believe that constipation may also occur as a result of the fiber absence. In addition, some believe that the replacement of cholesterol and foods high in saturated fat my increase the risk of developing heart disease. There are also some concerns that kidney problems may ensue as a result of the organs becoming overworked, but there are no scientific studies to support this theory as of yet.

The acceptance of low carb diet foods have had various impacts on some of the world's largest food producers. Pasta makers, for example, suffered a reduction in the need for their products and believed that the loss was connected to low carb diets. A popular doughnut manufacturer admitted that earnings were lower than usual and associated the reduction with low card diets, which reduced the demand for their product as well. Several companies, on the other hand, watched as their profits were on the rise as they promoted low carb products in stores and restaurants.
