About

The primary objective of this study is to investigate the safety and efficacy of a bone broth diet on weight loss in obese adults. The change in weight and body mass index (BMI) following the bone broth diet will be measured from baseline at Days 22 and 50. Additionally, the safety and tolerability of the bone broth diet will be measured by the occurrence of post-emergent adverse events (AEs).

Experimental group

Description:

During the bone broth phases, each week will be separated into 'fasting days' and 'feeding days'. There will be 2 non-consecutive fasting days and 5 feeding days per week. On fasting days, participants will be instructed to consume 1 packet of bone broth every 2 hours, for a total of 7 packets/day. On feeding days, participants will consume 3 meals/day, made up of 'Yes' foods portioned according to instructions provided in the Bone Broth Diet Quick Reference Guide and 1 packet of bone broth, twice a day, as snacks between meals. If a bone broth serving is missed participants are instructed to consume the serving as soon as they remember. Participants will be advised not to exceed 7servings of bone broth on fasting days and 2 servings on feeding days. During the maintenance phase, participants will not consume any bone broth.
