See, for me PGX doesn't really make sense. It's essentially an overpriced fiber supplement. It work by you ingesting the pills before you eat, drinking plenty of water so that the fiber expands and fills up your stomach making you eat less. Fiber (especially soluble such as pectins, psyllium etc) not only fill you up, but by doing so, slow digestion time and sugar absorption, therefore balancing out sugar levels which results in less cravings and "sugar crashes". It also helps regulate transit, prevent constipation, gently cleansing you digestive tract, absorbing toxins and carrying them out... In my opinion you are better off getting a much cheaper fiber supplement (such as psyllium, in bulk) and making in part of you daily habit. It'll not only help you manage hunger, craving (and weight) but help your overall health.
