The patented supplement, Appethyl, increased the feeling of fullness in study participants after just one dose. It also decreased cravings for salt, an important development for people who are being treated for high blood pressure.
Appethyl is an all-natural spinach extract enriched for thylakoids, the cellular membranes in plants which are found in chloroplasts where photosynthesis takes place. Thylakoids work by slowing fat digestion, which in turn increases the body's production of hormones that lead to a satisfied feeling. The extract is created through a specialized process that releases the active components in the spinach and renders them active when they're eaten.
The supplement is more beneficial at curbing cravings than fresh spinach because Appethyl is active the moment it's eaten. Spinach leaves must be digested before the full feeling occurs, thereby missing the window for hunger control.
In the study conducted at Pennington Biomedical, 60 overweight and obese participants were provided either Appethyl or a placebo with a meal and were monitored. Researchers found that participants who took Appethyl felt more satisfied, had a reduced feeling of hunger for food, and had less desire for salty and savory foods.
