Diet Soda.... to ditch the Diet Coke.... or not

Let me start this by saying that up until 2 weeks ago I was an avid fan and consumer of diet soda. My all time favorite Diet Coke. I started talking to a nutritionist and doing some research of my own. Here is what I've learned.
1) aspartame which puts the diet in diet soda is basically formaldehyde..yes what they use on dead bodies.

2) When your body consumes "fake" sugar it reads it has real sugar. Your organs treat it like real sugar. What happens over time though it continues to read the fake sugar as real sugar it realizes it does not provide the energy. This makes the body freak and hold on more to fat because it thinks its energy source is insufficient. Naturally over time it slows down your weight loss.
