Resveratrol Guide: SiRT1 has been discovered as the gene that lengthens lifespan through caloric restriction. When food is limited, SiRT1 is used to break down fat stores as a source of energy. It's part of the body's defense against starvation.
Animal experiments show that this gene is activated through caloric restriction, thereby lengthening lifespan, aiding in the metabolism of fat and cholesterol metabolism, increasing immune function, and boosting cardiovascular health. A lot of people are discovering the virtues of a calorie-restricted diet, but you should always speak to your doctor before trying it yourself.
When someone overeats, their fat stores send out inflammatory compounds that tell the liver to make it inflammatory. This action causes free radical damage throughout the body. As a person gains weight, this inflammation level also increases. The liver gets saturated with fat, which is then “cooked” by the inflammation that's running rampant. Eventually, liver damage will result. Arteries will also become choked with fat, raising blood pressure and cholesterol levels.
Leptin levels will elevate, causing irritability and possible insulin resistance, leading to type II diabetes. Leptin brings on food cravings, and the cycle continues.
Everyone who's overweight and has trouble with food cravings has leptin resistance, causing a false sense of starvation. Overeating and constant snacking are prime causes of leptin resistance. People don't have the equipment to deal with this problem because food has historically been scarce.
When you begin a diet, you'll clear the excess leptin from your body, diminishing those cravings. For a while, your body will burn calories based on your “set point”, until you hit that dreaded “plateau.” You can't further restrict calories because you'll get cranky, have trouble sleeping, and get sick more easily. This stress will also cause inflammation, which you're trying to avoid. You'd begin to break down muscle, which isn't good and can lead to anorexia. Resveratrol is a great way to aid weight loss and maintain energy levels.
Resveratrol will work well when you eat less and have cleared excess leptin from your bloodstream. It will also work if you aren't dieting, but a fat and calorie-laden diet can quickly negate its benefits. Losing weight will improve your heart health, and resveratrol will help here too. That alone makes it worth a look!
It has been shown to improve heart function in those with diabetes who'd had a heart attack. Its potent anti-inflammatory properties also help in eye and bone health, improve coordination, protect joints and the liver and pancreas, and regulate cell health.
That's quite impressive, just for one nutrient. Maybe there's something to resveratrol after all, and indeed you'll be hearing quite a bit more about this super-nutrient in the future!
