Regardless of method, weight always boils down to a balance of calories consumed vs calories burned.
Your control of calories burned is limited - outside of physical exercise, your body does a lot of crap on its own, and finding the number of calories you passively burn on an average day is a major hurdle.
To do that, log and calculate the caloric value of everything that goes into your mouth; and your weight. If your weight is trending up, reduce your intake and keep checking. Once it stabilizes, you've got your number. If your baseline is weird, something's fucking with your metabolism - see your doctor (for real, that could be a sign of some really bad shit).
From there, you can either further decrease calories consumed by eating/drinking less, or increase calories burned by cranking up the exercise, or a combo of the two. You'll be more comfortable/satiated if you limit things like processed shit, but you can literally eat nothing but Twinkies and still lose weight if you stay within your caloric budget (you'll also be starving all the time, pissed off, and unless you're a fucking robot, give in and eat some actual food, breaking your caloric budget and thus your goals, so don't actually try the Twinkie thing, but it's 'technically' possible).
Any and every diet that actually works does so via a caloric deficit. Maybe fructose is the biggest enemy; maybe it's other sugars; or fats; but keep your caloric consumption-to-burn ratio in the negative regardless of source, and you WILL lose weight.
Our bodies absolutely do not treat all calories equally
This.
It's crazy, the science on processed fructose vs glucose is clear
but people still cling to old ideas about all calories all being the same.
I think you’re arguing different things, or you don’t understand the top comment. They are explaining that gaining weight is a function of net calories. The article you linked is effectively explaining glycemic index, or the rate at which food can be converted into energy by the body. Both of these are compatible. It’s wise to eat low GI food so that you feel sated for longer, but you don’t have to. You can eat exclusively white bread and lose weight if your net calories are negative.
@JasSmith hmm maybe I linked to the wrong thing. I was trying to find one that pointed out the difference between glucose metabolism and fructose metabolism, as an illustration of how calories are not all treated the same way by the body, but I was in a hurry. This might be better.
Thanks for the link. If proven this would definitely be a bad outcome, but it doesn’t mean that a calorie deficit becomes a calorie surplus depending on the nutrient. If one is burning more than they’re consuming, the above is irrelevant insofar as weight gain is concerned. It’s relevant either way for diabetes.
