Weight Loss & Satiety Weight Loss & Satiety

As obesity rates continue to rise, weight loss and satiety remain high priority to consumers. With extensive experience in weight loss trials, food intake trials, and measures of satiety and satiation, INQUIS Clinical Research works with our clients to design and conduct trials unique to their study products and objectives.

Weight Loss & Satiety
Areas of Expertise
Appetite & food intake

Appetite and food intake studies are increasingly sought-after, as consumers continue to demand products that promote feelings of fullness.  At INQUIS Clinical Research, we conduct trials that investigate both subjective measures of satiety, including visual analogue scales and feelings of hunger measurement, as well as objective measures of satiety, such as unrestricted food intake studies.  With access to groups of both restrained and unrestrained eaters, as well as the ability to conduct studies that look at both satiation and satiety, we are able to design and execute the research trial that meets your needs.

Long Term Weight Loss

As obesity rates continue to soar, weight loss and weight maintenance continue to be priorities to consumers as well as food manufacturers. We have experience recruiting motivated and reliable participants for weight loss trials and managing the challenges of these longer-term studies. With the options of intervention periods followed by a follow-up maintenance phase, we can design a weight loss trial unique to your research needs.
We also examine changes in gut hormones and changes in body composition to better characterize the mechanism of action of your product.

Changes in body composition

Tracking changes in body composition over time with a specific treatment helps to better understand the mechanism of action as well as potential long-term effects. At INQUIS Clinical Research, our research includes DEXA (dual energy x-ray absorptiometry) scans to determine changes in fat composition over time, as well as BIA (bioelectrical impedance analysis) to monitor changes body fat percentages over time.

Gut hormones

Gut hormones are important indicators of satiety and may reveal the mechanism of action of your product. At INQUIS Clinical Research, we measure GLP-1, GIP, PYY, ghrelin, and adiponectin in order to achieve our clients’ research objectives when determining the effect of their products on feelings of fullness.
