They may be higher in carbs than other fruits, but the humble banana packs a very nutritious punch.

I'm often asked about my stance on bananas, and when I give them the green light some people will ask, "But aren't they fattening?" The truth is that bananas are a real power food-as long as you don't overdo it on the portion size.

An Appalachian State University study, which compared bananas to a sports drink during intense cycling, found that bananas offered several advantages. In addition to providing antioxidants not found in sports drinks, they pack more nutrients and a healthier blend of natural sugars. In the study, trained cyclists gulped either a cup of a carb-rich drink or downed half a banana every 15 minutes during a road race of two-and-a-half to three hours. Blood samples taken before and after revealed that the cyclists experienced similar performance effects, and a greater shift in dopamine-a neurotransmitter that plays a role in movement and mood-after eating the bananas. Some research also indicates that inadequate dopamine may be tied to obesity.

But bananas aren't just for athletes. While it's true that bananas do pack more carbs per bite than other fruits (because they're lower in water content), there's no need to shun them, even if you're trying to lose weight. Bananas are a rich source of potassium, an essential nutrient in the body which, in addition to reducing blood pressure, helps support muscle maintenance and acts as a natural diuretic that alleviates water retention and bloating. The high levels of vitamin B6 in bananas also helps maintain healthy blood sugar levels and is vital for the production of feel-good neurotransmitters like serotonin and norepinephrine. Bananas are also packed with fiber, which boosts satiety and improves digestive health.

More good news: Bananas are super easy to incorporate into your diet. In my newest book, S.A.S.S. Yourself Slim, I include several banana recipes, including my Green Tea and Vanilla Banana Almond Smoothie and Vanilla Almond Frozen Banana snack. They're also on the list of fruits you can use to build your own meals using my "five-piece puzzle" concept (meals made from specific portions of produce, whole grain, lean protein, plant-based fat, and natural seasonings).

Here are three of my favorite satiating but slimming banana-based breakfast and snack combos:

Open-faced AB&B

Spread one slice of toasted 100 percent whole-grain bread with 2 tablespoons of almond butter, top with a 5-inch portion of sliced banana, sprinkle with ground cinnamon, and enjoy with a cup of ice-cold organic skim or nondairy milk.

Banana muselix

Fold a 5-inch portion of sliced banana into 6 ounces of nonfat organic Greek yogurt or a nondairy alternative with one-quarter cup toasted rolled oats, 2 tablespoons sliced or chopped nuts, and a generous shake of ground nutmeg. Allow the mixture to sit in the fridge overnight for even more flavor, or freeze it to enjoy as an ice cream alternative.

Banana ginger chocolate parfait

Melt a quarter cup of dark chocolate chips, such as Dagoba Chocodrops, which are 73 percent dark. Fold in 1 teaspoon fresh grated ginger and one serving of a puffed whole-grain cereal like Arrowhead Mills puffed millet or brown rice. Layer the chocolate mixture with 6 ounces of nonfat organic Greek yogurt or a nondairy alternative and a 5-inch portion of sliced banana.

It's been a year since my husband practically threw me away like GARBAGE for being too fat and disgusting, as he called me.And that’s when I decided I’d had enough… No matter what it took I was going to look great! The first thing I wanted to do was to get rid of cellulite. After much trial and error, I finally found a program that taught me the correct body movements to stimulate all 90 muscles of my lower body and the right way to optimize my hormones through nutrient balance. The end result is astonishing. Cellulite is gone.The firmness and tightness of my body is something I've never felt before.I feel proud of myself. And so can you... Visit ==>

Hi, my name is Helen, I’m in my late 30's and I’m a mom of 3 adorable children. I’ve always struggled with my weight especially after the birth of my third child, 6 years ago.I just stopped taking care of myself. I believe that I let motherhood consume me and forgot how to be a woman. That is one of the main reasons why my marriage fell apart, 3 years ago. My husband didn't even want to look at me naked for years. He actually told me that he felt betrayed. And the worst part? I also felt I betrayed myself. I was feeling ashamed, guilty and embarrassed, which made me too weak mentally to be able to lose weight. Continue here >>>

Hi, my name is Kate and I would like to share my story. Up until about 2 years ago, I was 30 pounds overweight. Over the years I had followed many different diet plans, but failed every single time. I was "blessed" with a pear shaped body and no matter what i did, I always retained lots of stubborn fat in my lower body. Everything changed when I found the right diet program. My story is here ==>

Hi! You're doing everything to lose weight: loading up on healthy foods, making smarter choices while dining out, and exercising. A diet that fits all of us, whether we want to lose a few pounds or a lot or trying to get used to eating healthy and balanced. This is a diet that can be followed easily by cooking for the whole family, even permanently, to reduce and / or maintain our weight, but also to have the indicators of our health always good. If we can combine this program with gentle regular exercise, eg swimming, walking, jogging, bike the results will be spectacular. What if we're on a weight loss effort? We will spoil our diet and we will take back the pounds you so painstakingly lost? If you want to lose weight with natural way, check out this website:
