Fitness Man : proteins and weight loss

You probably already know that protein is crucial to building muscle. But did you know that it helps you burn fat as well? Now you have one more reason to like it.
Here's how it works:
No more insulin spikes

Taken alone, carbohydrates, specifically high-glycemic sugars, can cause insulin spikes. Getting some form of protein source to go along with your meals effectively keeps this from happening.
Cool. But what does it mean?
Well, a spike has two parts: a rapid increase and a rapid decrease. The first part is not so bad since it gives you a short energy boost. The problem lies in the second part. The rapid drop of insulin levels causes you to feel not only tired, but hungry-usually for other high-sugar foods-as well. SO make sure that you consume protein with most, if not all, of your meals.
No time to prepare protein-rich meals? Try instant sources like liquid egg whites instead. They're protein-rich and all-natural like regular egg whites but they come in a more convenient form.
Increased metabolism
Protein helps you build more muscle. Muscle is more expensive (in terms of calorie requirement) for your body to keep than fat. This means that the more muscle you have, the more calories you burn even when you're not doing anything.
The amount of extra calories burned may not be much according to some experts, but the little things add up. Besides, more muscle means you can work out harder and make your body a much more efficient fat-burning machine anyway so it's a win-win situation.
Decreased muscle breakdown

Your body prefers to use carbohydrates as its primary energy source because it's more readily available and easier to burn. However, the harder and longer you work at the gym, the bigger the risk that you'll run out of carbohydrates. When this happens, your body is forced to tap into your calorie stores, i.e., fat and muscle.
In the absence of readily available amino acids that come from dietary protein, your body feeds on your muscle instead. Less muscle, of course, results in a decreased metabolic rate and, over time, may also negatively impact your strength. So, the next time you hit the gym, bring a steady supply of ready-to-drink protein with you.
Tired of protein shakes? Grab a bottle of chocolate egg whites instead. They're a nice flavored alternative to regular liquid egg whites and your usual protein shakes.
