Unfortunately, many would still opt for the real sugar sodas..... This is not so much a case of caloric maintenance levels not being surpassed.. Higher ratios of high glycemic sugars consumed have a direct correlation to insulin sensitivity...and eventual insulin resistance over time....where excessive insulin is being released... This is known to negatively affect the basic tyrosine kinase activity of the insulin receptors located within our cell's membranes. Further, excessive depletion and higher demands of insulin production from our beta cells can also force these same beta cells(cells that produce insulin) to not adequately produce insulin later down the line.. Several ways of developing dm2. And disproportionate sugar rushes on a consistent level can be a strong causative effect... Which is why these type of diabetics may not appear obese
