But beyond that, experts aren't convinced that the keto diet has any other scientifically-proven health benefits. In fact, it may have some distinct downsides. If you follow the keto diet incorrectly, for example (like by eating lots of saturated fats, versus healthy unsaturated fats), you're at risk of raising your cholesterol levels. “The best strategy to keep your heart healthy is to get as much fat as possible from unsaturated sources such as olive, avocado and canola oils, nuts, seeds, avocados, and olives," says Ansel.
Your New Year's resolution diet should be based on a well-balanced eating plan that fits your lifestyle, rather than a weird fad replete with food restrictions. That's according to U.S. News & World Report's best diet rankings for 2018. The two diets that tied for the top spot -- the Mediterranean Diet and the DASH Diet -- fit that bill because they feature real food and reasonable, flexible guidelines, experts said.
I’ve been asked many times to provide an authentic Mediterranean Diet meal plan, and when we say authentic, we mean it! The reason for this is that most “Mediterranean Diet” meal plans I see online are anything but. Sorry, but edamame beans, minuscule amounts of  olive oil, canola oil, meat with every meal etc. are not part of a Mediterranean Diet.
The Mediterranean diet isn’t a regimented plan, like South Beach, the Blood Type Diet or any others; it’s more a way of eating. After World War II, researchers began studying the eating patterns of 13,000 middle-aged men in the US, Japan, Italy, Greece (including Crete), the Netherlands, Finland and Yugoslavia. They noticed that those in countries whose diets had been restricted by the deprivations of the war had lower rates of heart disease compared to American men. Moreover, residents of Crete enjoyed the best cardiovascular health, leading scientists to conclude that their diet — fruits, vegetables, grains, legumes and fish — played a major role.

Con: Results can vary depending on how much fluid you drink. By drinking more water, you dilute the concentration of ketones in the urine and thus a lower level of ketones will be detected on the strips. The strips don’t show a precise ketone level. Finally, and most importantly, as you become increasingly keto-adapted and your body reabsorbs ketones from the urine, urine strips may become unreliable, even if you’re in ketosis.
