Previously, experts thought that insulin levels became elevated in response to obesity and the insulin resistance that accompanies it. These new findings offer hope that treatments to keep insulin in a healthy range may reduce the risk of obesity and type 2 diabetes.
Previous notions have concluded that high insulin levels are a result of obesity; however this study based on animal research now suggests otherwise. People who follow a high-fat diet and meal plan by consuming small amounts of food and snacks throughout the day may experience weight gain because their bodies produce higher levels of insulin, which can lead to obesity, a risk factor for developing type 2 diabetes.
Further research needs to be completed to determine how these findings can be applied medically; however the findings suggest that different dietary patterns may contribute to healthy insulin levels. This can be accomplished by eating meals at regular times throughout the day, having smaller portion sizes and consuming fewer snacks.
