Check your carbohydrate intake.

Think about it, when you have a meal or snack, what percentage of it consists of carbohydrates? And, worse yet, is it a simple carbohydrate such as white bread, white pasta, rice, or sugar? Carbohydrates teach your body to run on carbs., thus keeping you hungry and tired between meals and snacks.

On the other hand, eating a diet rich in protein and fats allows your body to build and maintain muscle, stay anabolic, and burn fat for fuel. If your meal is 2/3 carb., you are better off with more meat and fat instead.

I've posted some great information about this here and here. Now, check out Stephan at Whole Health Source. He sums up the potent fat storage mechanisms carbohydrates support, be sure to read his whole post.

Since fat accumulation revolves around carbohydrate intake and insulin production, it makes sense that reducing carbohydrate causes weight loss. No more carbohydrate = a lot less glucose, and a lot less insulin to deal with it. This completely sidesteps the problem of insulin resistance, although that seems to respond favorably to carbohydrate restriction as well. Every time true low-carbohydrate diets are matched head-to-head with reduced-calorie, carbohydrate-rich diets, subjects lose more weight and have fewer problems with hunger on the low-carbohydrate diet. I discussed a recent study here.

The idea that you can achieve and maintain a healthy weight without cutting calories sounds too good to be true. In fact, all it represents is a return to our natural pattern of eating as human beings. It may involve breaking an addiction to carbohydrate. True hunter-gatherers eat between 0 and 35% of their calories as carbohydrate, and no refined carbohydrate. In industrial nations, we eat approximately 50% of our calories as carbohydrate. Hunter-gatherers also exercise regularly, and don't eat Frosted Sugar Bombs for breakfast. This helps maintain good insulin sensitivity. Since we are genetically nearly identical to our hunter-gatherer ancestors, we would be wise to learn from their example.

There's no need to be hungry; eat meat and understand this.
