About
The purpose of this clinical study is to determine the effect and safety of long-term intake of enzymatically modified isoquercitrin (EMIQ), a natural plant product on body fat loss in obese and overweight individuals.
Full description
This study is being conducted to assess the effect of supplementation with Enzymatically Modified Isoquercitrin (EMIQ) vs. placebo on measures of total body fat in overweight and obese adults. Participants will visit the HNRCA on 5 different dates.
Visit 1: Participants will receive materials and instruction for completing 24-hour dietary recalls to be completed by phone a week prior to the next visit.
Visit 2: Overnight fasted participants will arrive to the Human Nutrition Research Center on Aging (HNRCA). Vital signs, and EKG measure of heart rhythm, scrub weight and height will be obtained. Blood samples will be collected. Several baseline measurements will be performed during this visit including: lipid profile, insulin test, adiponectin, a urine dip stick, skinfold thickness and waist/hip circumference, resting metabolic rate (RMR), and DXA measure of total body fat. A three factor eating questionnaire, food craving questionnaire, and the Stanford 7-Day Physical Activity Recall (PAR) will be administered to assess volunteer's dietary inhibition, restraint, hunger, cravings and physical activity level. EMIQ and placebo capsules, compliance calendar, and instructions will be dispensed to participants by nursing staff.
Visit 3: Overnight fasted participants will arrive to HNRCA four weeks from the last visit. Participants will be asked to return their unused supplements as well as their compliance calendar. Vital signs, scrub weight and changes to volunteer health, medication and eligibility status will be assessed. Blood samples will be collected. A second EKG will be performed. The PAR will be administered. Before their next visit, participants will complete 3 24- hour dietary recalls by phone.
Visit 4: overnight fasted participants will arrive to HNRCA four weeks from the last visit. Participants will be asked to return their unused supplements as well as their compliance calendar. Vital signs, scrub weight and changes to volunteer health, medication and eligibility status will be assessed. Blood samples will be collected. The PAR will be administered. Before their next visit, participants will complete 3 24- hour dietary recalls by phone.
Visit 5: Overnight fasted participants will arrive to HNRCA four weeks from the last visit. Vital signs and scrub weight will be assessed. Blood samples will be collected. Final measurements will be taken during this visit including: routine health screening analysis, lipid profile, adiponectin, insulin test, a urine dip stick, liver and kidney function (SGOT, SGPT, BUN, creatinine, and calculated GFR), skin fold thickness, DXA, RMR and waist/hip circumference. A three factor eating questionnaire, food craving questionnaire, and the PAR will be administered to assess changes in volunteer's dietary inhibition, restraint, hunger, cravings and activity level throughout the study.
