Just because we have silly laws already is not a good argument for adding more.

if people are just going to buy more sodas, why is it the restaurants and movie theaters who seem to care so much and people who are kind of like, whatever, i can just get a liter bottle at the grocery store? wouldn’t this be a good thing for those businesses?

Why do we do any laws about it? People can decide for themselves how much soda they want to drink, it’s not the governments job.

also, not dealing with sugar is not always diabetes. diabetes is a specific disease and it’s an insulin issue, and how your body deals with insulin affects how your body can deal with sugar. 

you can have a ‘sugar problem’ that isn’t diabetes, but type 2 diabetes is not genetic, and type 1 diabetes isn’t what anyone talks about when they are shaming fat people for their weight.

can you provide links to the research you’re talking about?

“As the story is told in John Love’s official history of McDonald’s, Wallerstein tried everything he could think of to goose up sales — two-for-one deals, matinee specials — but found he simply could not induce customers to buy more than one soda and one bag of popcorn. He thought he knew why: Going for seconds makes people feel piggish.
Wallerstein discovered that people would spring for more popcorn and soda — a lot more — as long as it came in a single gigantic serving. Thus was born the two-quart bucket of popcorn, the sixty-four-ounce Big Gulp, and, in time, the Big Mac and the jumbo fries…”so basically, people don’t want to go back for seconds. maybe that’s changed now that people have gotten used to big portions, but since the only real opposition i’ve seen to the ban has been in movie theaters, i’m willing to bet they don’t think people will be buying 2 medium drinks either. 

personally, i think the law should just stipulate that smaller portions be available. 

There’s also the caveat that most people with a good diet and some exercise will not reach that point, but for others, that won’t be enough.  Eating well and exercising do not guarantee that a person will have a small amount of body fat (I know plenty of “overweight” people who do both), and depending on the person’s individual DNA, that extra weight may or may not increase their chances of becoming diabetic.  No one even knows all of the factors that create diabetes, but studies have consistently shown that the single best way to avoid it is to reach or maintain a small amount of body fat.

high BMI’s are not causing diabetes, it is a “risk factor”. that just means that a lot of people with diabetes are overweight.since insulin “regulates uptake of glucose from the blood into most cells (primarily muscle and fat cells…” if you already have type 2 diabetes, which is not inherited according to wikipedia, having a lot of fat might be an issue? but then having a lot of muscle would be too. and you have to already have diabetes.

so, you’re wrong.

eta: and of course you don’t think only fat people buy large sodas.
