“The short answer is, no, you cannot effectively block carbs,” Dr. Ramprasad says via text. “The idea behind carb-blockers is that certain plant extracts (like white kidney bean or garcinia cambogia) supposedly inhibit enzymes that break down carbohydrates, so you absorb fewer calories. In practice, the effect in humans is very minimal to non-existent. So, no—there isn’t a supplement that actually prevents you from digesting carbs in a significant, reliable, or safe way. The “carb-blocking” claim is more of a marketing hook than a physiologic reality.”

Foodology Cutting Jelly, however, might blunt appetite a bit—just not in a way that will actually lead to meaningful weight loss. Dr. Ramprasad explains, “The stomach has a natural rhythm of emptying—fiber may slow down that rhythm.” In other words, swallowing a bunch of gel could create a sensation of fullness. Not because of any magical ingredient but because of a few basic bulking agents and sugar substitutes.

The ingredient list is a mix of fruit concentrates, lab additives, and animal extracts, like: European plum concentrate, D-Sorbitol β-Cyclodextrin, and fish collagen. But, really, it’s fiber, water, and fake sugar. Which, Dr. Ramprasad said, causes, “a clean out effect.”

Basically, this is a laxative—a sentiment more or less expressed in all these TikToks. The word “poo” is not technically banned on TikTok but for some reason, a lot of the captions swap ‘o’ for zero, like it’s a secret: “This will have you p0oping like nobody’s business #cuttingjelly.”

Going to the bathroom is not a dieting hack. It’s just something bodies do, ideally by themselves and not because you bought a big box of jello sticks. “The standard approach to weight loss is still diet, exercise, lifestyle change, and a consideration of medications like GLP-1s,” Dr. Ramprasad says.
