Weight gain or loss is just a numbers game of calories in vs calories out. Literally every diet that actually works boils down to a caloric deficit; and those that don't work are because they fail to cross that line.

Any time you substitute something high calorie for low, it's a step toward weight loss. So, artificial sweeteners (at least the zero calorie kinds like sucralose, aspartame, etc; not sure if high calorie sweeteners like high fructose corn syrup are considered "artificial" but it sure as fuck ain't natural) are extremely useful as a weight loss tool.

The study linked could replace artificial sweeteners with almost any weight loss tool and find the same result. "Study links people who sign up for an initial gym membership to increased body fat adipose tissue volume!!" ...like, no shit Sherlock, they're there to lose it.

Be careful not to draw the wrong conclusion from a misleading headline.
