Gwyneth Paltrow does it. 21 days of cleanse before her filming. So when my clients are looking for a magic bullet, I talk about diet and exercise. The best sustained weight loss comes from gradual reductions in fat and calories from your diet, but there is a quick sure fire way to boost your metabolism and drop weight quickly before an event.

Enter the Core Cleanse. A 7 day all veggie and water diet, this cleanse optimizes your bodies ability to absorb precious vitamins and minerals, boost your metabolism and use calories efficiently. It starts with 16oz of green tea with honey and cayenne in the morning, a large lunch from an approved list of veggies and a dinner shake, all totaling 1200 calories. This goes on for 7 days and many people don’t have the ability to finish it, but if you can muster through it, you will drop weight and look ridiculously slim.

During the cleanse, it’s best not to ramp up your exercise routine. You want to go easy on yourself since you are taking in less calories than usual.
