As can be seen from fig. 1, the two-hour postprandial blood glucose response of the protein stick for weight management (11 subjects) is different from typical high GI foods such as glucose and white bread, and no rapid rise and fall of blood glucose concentration occur. The concentration of the blood glucose curve of the protein rod for weight management in the first 60min is obviously lower than that of glucose, and the concentration of the blood glucose curve in the last 60min is higher than that of the glucose, and shows a trend of slowly rising and slowly falling; wherein the 60min time point becomes the lowest point of 2 hours post-prandial blood glucose excursions for the protein stick for weight management.
The broken line in fig. 2 shows the value of satiety, and the bubble size shows the number of persons (11 persons) with satiety at the critical point or more, and 6.25 is the critical point of hunger and satiety. The protein bars for weight management generally showed a greater satiety than glucose, both from the overall satiety mean and from the time-interval satiety population analysis. The satiety of glucose shows a tendency to rise and fall rapidly in the first 60min, where both the satiety mean and the satiety population reach a peak at 15min, the satiety mean has fallen below the critical point after 30min, and most has been under hunger after the last 60 min. The protein bar for weight management was shown to provide a very good feeling of satiety for almost all subjects and slowly decline 60min before the meal, maintaining a feeling of satiety above the critical point and more than half of the population feeling satiety until 90min, and only slowly decline at 120 min.
It will be appreciated by persons skilled in the art that the embodiments of the invention described above and shown in the drawings are given by way of example only and are not limiting of the invention. The objects of the invention have been fully and effectively accomplished. The functional and structural principles of the present invention have been shown and described in the examples, and any variations or modifications of the embodiments of the present invention may be made without departing from the principles.
