bromocriptine is clinically used for Hyperprolactinemia, Parkinson's Disease and Acromegaly. Lyle McDonald has written extensivly about the possible use of bromocriptine to aid weight loss.

OBJECTIVE: A double-blind placebo controlled study investigated long-term effects of Ergoset, a new quick release formulation of bromocriptine, on body weight, body fat, and glucose tolerance in a group (n = 17) of obese subjects who were instructed to follow a moderate hypocaloric diet. RESEARCH DESIGN AND METHODS: Obese individuals (> 25% body fat for men and > 30% body fat for women) were instructed to follow a calorie-restricted diet (70% of weight maintaining based on study entry weight) and were randomized to daily treatment with Ergoset (1.6-2.4 mg/day) or placebo at 0800 over an 18-week treatment period. Oral glucose tolerance tests were performed on subjects before initiation and again at termination of treatment. Body weight and body fat (determined by skinfold measurements) were quantified every 2 weeks during the course of treatment. RESULTS: Ergoset treatment for 18 weeks significantly reduced body weight and body fat versus placebo (6.3 +/- 1.5 and 5.4 +/- 1.1 kg vs. 0.9 +/- 1.0 and 1.5 +/- 0.6 kg. respectively, P < 0.01). Ergoset, but not placebo, also improved glucose tolerance (P < 0.02); the stimulated area under the oral glucose tolerance curve was reduced by 46% (from 121 +/- 23 to 64 +/- 32 mg.h-1.dl-1), while the stimulated area under the insulin curve was reduced by 30%. CONCLUSIONS: When combined with instruction to follow a moderate hypocaloric diet, Ergoset, but not placebo, improves glucose tolerance and promotes significant weight and body fat loss in obese subjects over an 18- week treatment period.

Timed bromocriptine administration reduces body fat stores in obese subjects and hyperglycemia in type II diabetics.

Obese postmenopausal female volunteers were given timed daily oral dosages of bromocriptine, and tested for reduction of body fat stores. This dopamine agonist has been shown to reset circadian rhythms that are altered in obese animals and to reduce body fat levels in several animal models. The participants were instructed not to alter their existing exercise and eating behavior during treatment. Skinfold measurements were taken on 33 subjects as indices of body fat. The measurements (e.g., suprailiac) were reduced after six weeks by about 25%, which represents a reduction of 11.7% of the total body fat. These dramatic decreases in body fat, which are equivalent to that produced by severe caloric restriction, were accompanied by more modest reductions of body weight (2.5%), indicating a possible conservation of protein that is usually lost as a consequence of such caloric restriction. The effects of bromocriptine treatment on body fat and hyperglycemia were also examined in non-insulin dependent diabetics being treated with oral hypoglycemics (7 subjects) or insulin (7 subjects). Total body fat was reduced by 10.7% and 5.1% in diabetics on oral hypoglycemics and insulin, respectively, without any significant reductions in body weight. Hyperglycemia was reduced in most of the 15 diabetic subjects treated leading to euglycemia and even cessation of hypoglycemic drugs in 3 of the 7 subjects during 4-8 weeks of bromocriptine treatment. These findings support the hypothesis that obesity and type II diabetes may be treated effectively with bromocriptine when administered at the proper times and dosages.
problem is, what works in post-menopausal women does not neccessary work pre menopause. The first study was sponsored by the manufacturer, so it might be overstating the results.
