Brief summary

The purpose of the study is to determine whether Appethyl™, made from spinach, will reduce appetite and hunger given on the same day of testing.

Detailed description

Four hours after breakfast a small amount of liquid to drink will be given to a participant that will contain either the Appethyl™ or placebo. Participants will be given a lunch of about 750 calories and 40% fat prepared by the Metabolic Kitchen and be asked to eat all of it. Participants will have food choice testing performed 4 hours after starting their lunch meal. This will be done in two ways. Participants will be given a list of two foods that are made of carbohydrate like bread and pretzels and be asked which is most preferred. Participants will also be given a list of foods that differ in the amounts of fat, carbohydrate and protein that they contain and will be asked to mark the ones that appeal to them. Participants will be presented with a pizza in a quantity more than they could reasonably be expected to eat 5 hours after the start of their lunch meal and be asked to eat to their satisfaction over 30 minutes. Participants are not expected to eat all of the pizza.

Interventions

DIETARY_SUPPLEMENTAppethyl™

Four hours after breakfast participants will be given a small amount of liquid to drink that will contain Appethyl™. They will not know which they are getting and it will be decided randomly, like flipping a coin. Participants will be presented with a pizza in a quantity more than they could reasonably be expected to eat 5 hours after the start of their lunch meal and be asked to eat to their satisfaction over 30 minutes. Participants are not expected to eat all of the pizza.

OTHERPlacebo

Four hours after breakfast, participants will be given a small amount of liquid to drink that will contain a placebo (inactive liquid). Participants will not know which they are getting and it will be decided randomly, like flipping a coin. Participants will be presented with a pizza in a quantity more than they could reasonably be expected to eat 5 hours after the start of their lunch meal and be asked to eat to their satisfaction over 30 minutes. They are not expected to eat all of the pizza.

The scale ranged from 0 to 100mm; the higher values indicated greater outcomes.
