Some individuals are more inclined to be subject to Insuline resistance more than others and studies have shown that regardless of the number of calories and excercise done during a day, it is in fact the resistance to the Insuline which plays a major role in the fat storage. So a person can eat 1500 calories a day and does daily cardio, weight lifting + eat clean food but gains more weight than an individual who eats 2000 calories and do the complete opposite. What are the supplements or products that reduce the Insuline resistance? Out of my head, we can list some natural products to be taken during meals: - spirulina - apple cider vinegar What are the other products that are really efficient for fat loss due to Insuline resistance? This issue is present more often with women and people with diabetes. NOTE: Recent studies have shown that Metformin has no effect in Insuline resistance and have massive side effects and can cause dementia and alzheimer.
