I don't know why products like Phaseolamin have fallen out of favor as this is an OLD SCHOOL supp from years ago. These are MUCH more beneficial for the DIETING (not necessarily recomping) low carb crowd for carb-laden and potentially damaging binges.
Rather "encouraging" but I would like to see two or three more studies from independent centers to have a better understanding of the benefits and side effects of phaseolamin.
For those obsessed with insulin-reducing (.... ....)
Phaseolamin weight loss study
A Dietary Supplement Containing Standardized Phaseolus vulgaris Extract Influences Body Composition of Overweight Men and Women. Int J Med Sci 2007. Cosmetic Research Center, dell'Università Cattolica di Roma, Rome, Italy
A randomized, double-blinded, placebo-controlled study was done on 60 pre-selected, slightly overweight volunteers. The volunteers were divided into two groups, homogeneous for age, gender, and body weight. Phaseolus vulgaris extract and the placebo were taken one tablet per day for 30 consecutive days before a main meal rich in carbohydrates. After 30 days, subjects receiving Phaseolus vulgaris extract with a carbohydrate-rich, 2000- to 2200-calorie diet had greater reduction of body weight, BMI, fat mass, adipose tissue thickness, and waist,/hip/ thigh circumferences while maintaining lean body mass compared to subjects receiving placebo.

Phaseolamin Research: Effects of decreasing intraluminal amylase activity on starch digestion and postprandial gastrointestinal function in humans. Layer P.Gastroenterology. 1986.
We used an amylase inhibitor preparation that markedly improves postprandial carbohydrate tolerance in humans to investigate the effects of decreased intraluminal amylase activity on digestion of starch and postprandial gastrointestinal and hormonal responses. Four fasting volunteers were intubated with an oroileal tube to obtain duodenal, jejunal, and terminal ileal samples. After intubation, subjects ingested 50 g of rice starch given with placebo; on the second day, starch was given with the amylase inhibitor. Compared with placebo, the amylase inhibitor significantly reduced duodenal, jejunal, and ileal intraluminal amylase activity by more than 95% for 1-2 h; increased postprandial delivery of total carbohydrate (glucose polymers in particular) to the distal small bowel; increased breath hydrogen concentrations; decreased intestinal water absorption and increased distal intestinal volume delivery to the distal bowel; shortened duodenoileal transit time but doubled postprandial gastric emptying time; reduced the early postprandial plasma glucose rise by 85% and eliminated the late postprandial glucose fall to below fa sting levels; and abolished postprandial plasma concentrations of insulin, C-peptide, and gastric inhibitory polypeptide. Postprandial trypsin output was not influenced. We conclude that more than 95% inhibition of amylase reduces dietary starch digestion within the small intestine and uptake of dietary starch from the small intestine, markedly decreases postprandial release of insulin and gastric inhibitory polypeptide, and may alter postprandial upper gastrointestinal motor function.
