Can insulin resistance cause weight gain

Summary We hypothesize that 1 the initiating defect is HI that increases nutrient consumption and hyperlipidemia HL ; 2 the cause of HI may include food additives, environmental obesogens or toxins that have entered our food supply since ; and 3 HI is sustained by HL derived from increased adipose mass and leads to IR.

Inactivity does not cause obesity. Body Weight is Maintained in the Short Term Despite Variation in Intake and Activity The regulation of body weight involves many factors of varying degrees of importance but nevertheless appears to be stable in the short term despite dramatic variations in daily caloric intake and energy expenditure [ 11 ]. Alternative Testable Hypotheses Relevant to HI KO Animal Models Rodents have two insulin genes: Ins1, the expression of which is mostly restricted to the pancreas, and Ins2, which displays expression in both the pancreas and the brain.

Insulin Inhibits FA Oxidation and Lipolysis A major function of insulin is inhibition of lipolysis, an appropriate response to food ingestion and the need to promote fat storage.

Effects of HI on Neural Pathways Insulin signaling is critical in both central and peripheral mechanisms of nutrient handling [ 35 ]. Insulin is a potent storage signal to fat, brain, liver and muscle: Evidence for a causative role for HI in animal model obesity The discovery of insulin by Best et al. Effect of Reducing HI Both pharmacological and nutritional approaches have been used to reduce hypersecretion of insulin as a method for weight loss Diazoxide promoted enhanced weight loss in obese adults when combined with an 8-week energy-restricted diet [ 81 ].

Open in a separate window. Effect of Bariatric Surgery on HI Bariatric surgery is currently the only way to reliably induce sustained weight loss in obese humans. Conclusion Our goal in this brief perspective has been to question the dogma explaining obesity and underpinning the therapeutic guidelines for treatment that are largely unsuccessful.

Findings from a recent review suggest that structured exercise programs could offer significant benefits for people who have insulin resistance and type 2 diabetes. Healthcare providers can share valuable resources with people struggling to maintain a healthy body weight. Registered dietitians RDs can advise people about what foods to eat and avoid based on their current health status and goals.

RDs can even develop personalized meal plans. Healthcare providers can also recommend ways for people to improve their health while lowering their risk of developing diseases, such as diabetes, obesity, and cardiovascular disease. These tests can give people an idea of their overall health status.

People can use this information to track their progress toward achieving their health goals. Certain foods can help prevent weight gain. Developing a meal plan with a balance of nutritious foods can help. Speak to a nutritionist about this, if possible.

High-quality, unprocessed foods contain less added sugar and fat. These foods increase feelings of fullness and help avoid overeating. Insulin plays several essential roles in the body. It regulates blood glucose levels, promotes fat storage, and even help breaks down fats and protein.

However, excess insulin, due to insulin resistance or taking diabetes medication, can lead to weight gain. People can use dietary and lifestyle changes to prevent insulin-related weight gain. Getting regular exercise and eating unprocessed foods, such as fruits, vegetables, and whole grains, may help prevent excess fat storage.

For anyone struggling to maintain a healthy body weight after making dietary and lifestyle changes, it may be a good idea to consult a healthcare provider. They can offer valuable guidance for people trying to maintain or lose weight.
