I was rereading an article I posted awhile back and found something that made me think of you and your lipids.
And here's the relevant passage:
One of the key researchers in this area, Donald Layman, Ph.D.6, from the University of Illinois, has published many papers on the subject. He has found that the high protein, leucine rich diet, in combination with lower carbohydrates (150 grams or 600 calories per day) is effective to support weight loss, blood sugar metabolism, and a variety of factors that have an impact on cardiovascular health.
His research points out that during weight loss our bodies can easily lose muscle mass (and bone for that matter). Leucine has a direct signaling effect on muscle that prevents muscle loss during weight loss. This means that on a high protein diet, the weight that is lost is mostly fat, not muscle. Whereas on a high carbohydrate weight loss diet, much more muscle is lost.
Leucine directly communicates to insulin, instructing it to work efficiently in muscle. This not only helps preserve muscle mass, but also helps muscles use glucose as fuel, in turn supporting healthy insulin function.
This high protein, leucine rich diet invariably lowers blood levels of triglycerides, which helps leptin7 get into your brain easier so that you feel full on fewer calories. Once leptin gets into your brain correctly, leptin resistance8 is reduced, and your metabolism gets a go signal. Whey protein is especially helpful in improving your brainís feeling of food satisfaction9. Many bioactive peptides in whey regulate appetite, a benefit attainable only from consuming whey protein10 in higher amounts.
The important HDL Cholesterol needs adequate dietary protein in order to form its structure. We now know that HDL proteins get ďspentĒ as HDL works to help clear LDL cholesterol. If you donít have adequate protein you canít make quality HDL at an optimal rate. A higher protein diet supports HDL formation while lowering triglycerides, a two-pronged benefit that not only helps weight management but also supports a healthier lipid profile for cardiovascular well-being.
Layman points out that having a high protein breakfast11 is needed to maximize these benefits of protein, which is consistent with rule #4 of the Leptin Diet: Eat a breakfast containing protein.
