What's up DJ'ers!!!

Quick question for some of my fellow health nuts, is there a sure fire way to jumpstart my metabolism?

Just a quick summary of my current exercise and diet:

1/ Dieting several weeks: So I've reduced my caloric intake (probably too severly) the last several weeks. I've noticed a difference in my waistline (belt notches and pants fit different), the scale and the mirror. All are validating that the diet is taking effect.

2/ Keeping my protein up: I'm still spreading 200g of protein across 6-7 meals a day. It's tough to do, but I don't want to cannibalise my muscle.

3/ Lifting intensely: Still hitting the weights hard 4-5 times a week.

My main goal is to go from 200 lbs (20% body fat) to 174 (10% body fat). I'm currently at 194 after two weeks of dieting.

I feel the diet and exercise routine I'm following is effective, but I'm REALLY worried about shutting down my metabolism. Is there any way that I can ensure I keep my "furnace" burning? Maybe by adding some high intesity cardio (sprints)?

the only thing you can do is a refeed day with plenty of carbs and protein and NO fat(should be something like 20g).......VERY difficult to pull off.

the secret is, do not reduce total calories by much, just make sure you do a lot of excersize and that you have a low fat diet. Get a lot of calories from fruit, you got to do a lot of sport and because of this you should be eating like at least 2000 calories a day or even more just make sure you do a lot of excersize. If you eat to little your motabilism rate falls. Low fat and lots of excesize will not lead you wrong.
