[Evaluation of the action of glucomannan on metabolic parameters and on the sensation of satiation in overweight and obese patients].

The authors studied the behavior of body weight, blood glucose, total serum cholesterol, and hunger and satiety sensation in 30 patients treated for 60 days with a 1.200 kcal (5040 kj) diet plus either placebo or glucomannane. All the variables considered show that the low-calorie diet plus glucomannane is more effective than the low-calorie diet alone.
