(WFLX) - We're all looking for that quick fix to get in shape, and a lot of it has to do with what we eat. So we looked at some of the top diets from around the world to see how they work.
We started with South America,where the hot Latin diet is all the craze. It involves seven super foods that are spicy and flavorful like cilantro, chickpeas and avocado. Those foods help flush out toxins and increase your metabolism.
"The concept is you put them into your food, not only will it be helpful from a health perspective, but it will also allow you to have smaller portions because things that are tastier nip your tastebuds, and you're satisfied," says nutritionist Marlo Mittler.
While Mittler says it can work, you have to put in a lot of time to cook the meals.
Then, there's the Dukan diet from France. Kate Middleton was rumored to have been on this diet for her royal wedding. The diet incorporates high protein foods.
"It's very high in protein, and we know that too much protein affects your kidneys, and you can develop kidney stones and kidney damage," said Mittler. "It tells you in the first few days, you're going to feel like you have the flu. It's not the flu, it's your body's reaction," Mittler says any diet that makes your body react that way is not worth it.
In Japan, the morning banana diet has you eating one to four bananas every morning. "The concept is the banana has a resistant starch that is digested in your lower intestine so you stay fuller longer, and bananas are nutritious with lots of potassium and vitamins and minerals," said Mittler.
But bananas can also be constipating, and Mittler says eating the same thing everyday is hard to stick with.
The ice cube diet from Israel is one of Mittler's favorites. You can eat what you want, but before your biggest meal, suck on an ice cube with Hoodia in it. Mittler says Hoodia has a natural ingredient that curbs the appetite. "It sends a signal to your brain after you've had it that you've already eaten, the same way your blood sugars would rise after having your carbohydrates. So without food it has you less hungry," she said.
If done the right way, any of these diets can help you lose weight. But if you want to keep the weight off, Mittler says the bottom line is exercise and healthy eating.
