|*5-10 % reduction from their baseline weight with life style modifications.||*Pooled data from clinical trials suggest that people given orlistat in addition to lifestyle modifications, such as diet and exercise, lose about 2–3 kilograms (4.4–6.6 lb) more than those not taking the drug over the course of a year.* Orlistat also modestly reduces blood pressure, and appears to prevent the onset of type 2 diabetes, whether due to weight loss itself or to other effects; in a larger randomized controlled trial, orlistat was found to reduce the incidence of diabetes by nearly 40% in obese people.||* In clinical trials, people treated with the highest dose of phentermine/topiramate ER in combination with a program of diet and exercise lost 10% to 11% of their body weight compared to 1% to 2% for those who received placebo. In addition, 62% to 70% of subjects receiving the recommended dose or top dose of phentermine/topiramate ER achieved ≥5% weight by week 56 (ITT-LOCF) compared to 17% to 21% of those receiving a sugar pill.|
