I can't tell if you are being sarcastic or agreeing or not.
Usually your comments are good so I am going to believe you are sincere here.
Somewhat related I am one of those people who needs to make a change as I get >1000 calories from soda a day. I did quit years ago (just cold turkey) and after the initial headaches and tiredness the biggest change I saw was that I was constantly hungry. Much like quitting smoking made me for quite a while.
Coke has a lot of sugar in it. Some people drink a small amount of coke, and get pleasure from it, and are not fat.
Increasing portion sizes (see for example the increasing sizes of servings in McDonalds menus) mean that people now drink huge quantities of this sugary drink.
The volume of drink, the quantity of the sugar, is the problem.
Two cookies are not a problem. Two packets of cookies are a problem.
I'm not sure why you would think the response was sarcastic. Coke having sugar is NOT the issue. Drinking literally liters of it each day is certainly the issue. On top of a normal diet all those extra calories are bound to be a problem.
Now it seems silly but while I was going through the thread many responses had something worded similarly. After reading so many of those comments I was probably primed to see negativity everywhere.
eg.
It's not THIS it's THAT. (It's not sugar, it's sugar in excess.)
