Fiber supplement that increases fullness. Modest weight loss effect. Take before meals if you want to try it.
Glucomannan is a water-soluble dietary fiber extracted from the root of the konjac plant. It's one of the most viscous fibers known, absorbing up to 50x its weight in water.
The appeal: It expands massively in your stomach, creating a feeling of fullness that helps you eat less.
Glucomannan absorbs 50x its weight in water (psyllium only absorbs 10-20x). This creates significant stomach volume, triggering satiety signals.
The gel formed in your stomach takes longer to digest, keeping you full for extended periods and reducing post-meal hunger.
Glucomannan may reduce the absorption of fats and carbs by up to 10%, though effects are modest.
Research on glucomannan is mixed but generally positive for appetite control:
Reality: Effects are real but modest. It's a tool, not a solution.
Dosage: 1-3g (2-4 capsules) with 16oz+ water, 30-60 minutes before meals
Critical Safety Note: MUST take with plenty of water. Glucomannan can expand in your throat and cause choking if not taken properly.
Timing: Before your largest meals when appetite control matters most
Glucomannan: More powerful water absorption (50x), better appetite suppression, but higher choking risk
Psyllium: Safer, cheaper, gentler on digestion, but less dramatic effects
Which to choose? If you struggle with extreme hunger and can follow directions carefully, glucomannan. If you want a safer, more versatile fiber, psyllium.
Glucomannan is an effective appetite suppressant with real science backing it.
It works by making you physically full, not by "boosting metabolism" or other marketing BS. If you take it correctly (with plenty of water!), it can help you eat less and stick to your diet.
Is it a miracle supplement? No. Will it help if hunger is your main problem? Yes.
