I also never believed this, but now I am a convert. First, my whole life I have not eaten a lot of food and have been reasonably active. But always been 30 lbs overweight. Never been able to lose it. Always hit the dreaded "super plateau" about 15 lbs down. I also lived on Diet Pepsi for my life since being a teen. It is the only thing I drink.
Recently however, I finally heard a reasonable explanation for a diet drink slowing you down. It dehydrates you. It contains phosphoric acid and can actually use up 32 oz of water trying to clear one small can of Diet Pepsi. Water is H2o, so that means it contains oxygen which increases your metabolism. Say one diet drink and the associated water loss drops your metabolism by just 10% (1500 BMR), you don't burn 150 cals per day.
You can drink 64oz of water a day and have even one diet soda can destroy 1/2 of that effort. Add one cup of coffee and most of that water can be eliminated from your system.
I have never bought the "sweet taste" ='s insulin, because I have had my levels tested when I was taking 10 diet pepsi cans per day and never saw anything unusual.
