Here are some suggestions:
1. Start with a detox protocol
These normally include various herbs that cleanse and rejuvenate the liver and cleanse the intestinal tract—we usually recommend a product called whole body cleanse by integrative therapeutics (however, there are many excellent products out there).
2. There are some supplements that can help curb the excess calories from overindulging
One would be carbohydrate grabbers—they block the absorption of about 30% of carbohydrates in a high carb meals (white kidney bean extract is the most common one used. Next would be fat grabbers: these products reduce the amount of fat absorbed when you eat high fat meals—these include supplements like Guar gum, chickweed, and chitosan). Finally there is a supplement called 7-keto DHEA, which can help speed up your metabolism.
