Artificial Sweeteners Associated With Weight Gain, Heart Problems In Analysis of Data From 37 Studies (npr.org)

An anonymous reader quotes a report from NPR: The theory behind artificial sweeteners is simple: If you use them instead of sugar, you get the joy of sweet-tasting beverages and foods without the downer of extra calories, potential weight gain and related health issues. In practice, it's not so simple, as a review of the scientific evidence on non-nutritive sweeteners published Monday shows. After looking at two types of scientific research, the authors conclude that there is no solid evidence that sweeteners like aspartame and sucralose help people manage their weight. And observational data suggest that the people who regularly consume these sweeteners are also more likely to develop future health problems, though those studies can't say those problems are caused by the sweeteners.

The review, published Monday in the Canadian Medical Association Journal, looked at 37 studies. Seven of them were randomized trials, covering about 1,000 people, and the rest were observational studies that tracked the health and habits of almost 406,000 people over time.

    There's many ways that it could have that effect. The part of the puzzle you're missing is poop. Calories in exercise + calories added to fat stores + calories in poop = calories taken in.

    The number of calories left in the poop can be dramatically different depending on how the digestive tract is working. Different bacterial flora in the intestines can lead to dramatically different absorption rates of calories from some foods.

    Certain foods (I don't know if artificial sweeteners are one, but it wouldn't surprise me) dramatically affect the bacterial flora.

    I should start putting actual sugar in my coffee again

    No. You should give up sugar to the extent possible and just not expect
    artificial sweeteners to help much with that goal, and don't expect them
    to be entirely harmless.

    (I'd not worry about the added sugar in stuff like ketchup, unless you find
    yourself eating large quantities of it, but do keep an eye on food labels
    and eliminate anything that has way more sugar than you'd expect.)

    An occasional life saver, sucked not chewed, should be able to take the
    edge off at first when you hit a severe jag... note that one 12oz can of
    sugared coke is 3 of those, despite not even being very sweet compared
    to the sucralose diet coke, and not much sweeter than the aspartame
    diet coke.

    I've quit daily sugar intake twice now; it is not easy for some people to do.

    I had been off sugar for about a decade, started indulging again, and
    gained 10lbs in a year. Am now still considered overweight by 5lbs despite
    being mostly back off the sugar, but weight has more or less stabilized.
    Cholesterol went down after getting back off, as well.

    During that whole decade before the weight gain I was drinking more sucralose
    and aspartame than anyone would think healthy. Still am. There is no "artificial"
    taste for me anymore... sugar actually tastes weak and underwhelming. The
    artificial sweeteners probably do screw up the gut a bit... but sugar is worse overall.

    Drink something that tastes better than coffee. or better coffee; you won't need
    to sweeten it so much.

    The parent shouldn't be marked as a troll. Studies have shown that your body reacts to these sweeteners as if they were sugar. Meaning your body will release insulin in anticipation of the food spiking your blood sugar. However that spike never happens so excess insulin ends up causing low blood sugar levels and that signals you to eat more. So yes, using artificial sweeteners will cause you to eat more calories even though they don't have any.
