I have to agree about the vegetables. The vitamin is good insurance. Read up on Fish oils. They will help you lose weight. I does make sense that eating fat will help you lose fat, but it will help.

BTW: I found this tip from John Berardi this morning. I think it is right on:

FOOD TIPS
My most important tip - far and away - is the idea that carbohydrate intake should be activity-dependant.

So, simply put, the typical recreational exerciser saves his or her starches (pasta, bread, oatmeal, rice, etc) and sugary carbs (sweets, recovery drinks, sports drinks, etc) until they're exercising or immediately after. The rest of the day is for proteins, good fats, and lots of veggies (along with some fruits).

By following this rule, my typical clients see BIG, IMMEDIATE body comp changes! And, truly, this tip has been the biggest in terms of body composition impact for my recreational exercisers since they're typically only exercising 3-4 times per week.

We often have clients who swear that they're at 90% compliance (the gold standard for Precision Nutrition) and then, upon using the compliance grid, find out that they're really at 50% or 60%.

Hope this helps.
