If you are still eligible for this study, you will have about 6 teaspoons of blood drawn, for baseline routine tests. Your height and weight will be measured. You will be instructed by a research nurse to recall your one day food intake before starting treatment. You will be asked about any medications you are taking (especially any appetite stimulants, such as megestrol, corticosteroid, and marinol), including the dose and when you take them. If you are able to tolerate the taste of Haelan, you will be instructed to drink 4 ounces of Haelan soy beverage 2 times a day, on an empty stomach, for 8 weeks. You may add water, stevia, honey or artificial sweeteners into Haelan prior to drinking it to improve the tolerance of Haelan. If you are unable to tolerate 4 ounces of Haelan twice a day after 2 attempts, the dose will be reduced to 2 ounces twice a day. If you are still not able to tolerate it after 2 attempts, the dose will be reduced again to 1 ounce twice a day. If you still cannot tolerate drinking this Haelan dose after 2 more attempts, the dose will be reduced again to 1 ounce daily. If you cannot tolerate at least 1 ounce a day for 5 consecutive days, you will be taken off this study. If you vomit within half hour of taking the Haelan, you should try at least 2 more times to drink at least 1 ounce of Haelan on the same day. If unsuccessful, please record that you were not able to take the Haelan on that day. If you cannot tolerate at least 1 ounce of Haelan a day for 5 days in a row, you will be taken off this study.
