Diet Pepsi has plenty going for it as a 0 calorie, carb and sugar drink. The marketers behind it would be better off keeping it simple and pushing the Skinny Can (which is 12 oz., the same size as a normal soda can) to those looking to lose weight or quit drinking unhealthy soda, rather than those who already have a diet soda favorite. Call us stupid, but until sampling a six-pack of the Diet Pepsi Skinny Cans, we had no idea that Diet Pepsi tastes almost exactly like regular Pepsi. We canâ€t say the same for Diet Coke, which leaves a funky after-taste. Perhaps a money-back guarantee if it doesnâ€t taste like regular Pepsi would be a better hook than sending press releases and samples to fashion bloggers.

Now, switching to diet soda does have its downsides. For one, past studies have shown that those who drink diet soda tend to actually gain more weight because they think choosing a healthier soda means they can eat more. {CBS  News} Not to mention the fact that it is still, after all, soda. Though with Starbucks introducing ever larger cups (the better to accentuate the ever more minimal logo) that not so subtly encourage you to drink more iced coffee, tea or lemonade than some adult stomachs have room for, the mind trick of a taller, skinnier can that doesn’t actually contain any more soda than normal might not be so bad.

If youâ€re looking to improve your soda habits, and you know youâ€ll be able to simply substitute in Diet Pepsi for regular Pepsi, we highly recommend the product (though, oddly enough, the new can – a.k.a. the reason we were sent a product sample in the first place – really has nothing to do with our recommendation). But if youâ€re a water-drinker or you know you like to bargain with your diet, weâ€d say skip it. And if youâ€re a member of the fashion cult, rest assured you can keep sucking down the Diet Coke. We doubt Diet Pepsi will take over the fashion world just because of the Skinny Can. The one thing fashion loves more than skinny is its comfort zone.

What do these 4 names have in common? If you havenâ€t already guessed it, they are the names of some of the most famous diet plans. For many years, celebrities have sworn by these diets and their effectiveness in aiding the quest to stay in shape.

In the last 10 years, another diet regime has been steadily gaining popularity among celebrities like Courtney Cox-Arquette and Demi Moore – The Blood Type Diet. Recently, UK singer and X-Factor judge Cheryl Cole became the latest celebrity to advocate the diet plan in an interview with Hello Magazine.

So what exactly is this Blood Type Diet?

The Blood Type Diet was first introduced in a book entitled Eat Right 4 Your Type, written by Peter D’Adamo, a naturopathic physician in 1997. The premise of this diet is that people should plan their food intake around their blood type because the Lectins that exist in all types of food react differently with different blood types. D’Adamo further explains in his book that reactions with these Lectins are harmful for the body. In order to prevent this, it is important for individuals to select foods which can minimize these reactions.

Sounds good? Well, at least not according to some medical experts.

These experts typically agree that there is absolutely no scientific relationship between our blood group and the food we eat. Another concern of theirs was that the diets recommended for some blood groups are limited and cut out major groups of foods, which can result in a poor intake of nutrients required for good health. {Weight Loss Resources}

Yet, this has not deterred celebrities like Cheryl Cole, from singing praises of the Blood Type Diet. Cole revealed to Hello Magazine, that the plan “has made such a difference – not so much to my shape, but to how I feel and my energy levels. Before I was like ‘energy schmenergy†and didnâ€t believe it. But now I believe it 100 per cent.” {Healthy Hollywood}

Oprah Winfrey once said, “Diets don’t work.” Perhaps, that is the truth. Perhaps, there just is no such thing as THE perfect diet.
