Some negative side effects of a long-term ketogenic diet have been suggested, including increased risk of kidney stones and osteoporosis, and increased blood levels of uric acid (a risk factor for gout). Possible nutrient deficiencies may arise if a variety of recommended foods on the ketogenic diet are not included. It is important to not solely focus on eating high-fat foods, but to include a daily variety of the allowed meats, fish, vegetables, fruits, nuts, and seeds to ensure adequate intakes of fiber, B vitamins, and minerals (iron, magnesium, zinc)—nutrients typically found in foods like whole grains that are restricted from the diet. Because whole food groups are excluded, assistance from a registered dietitian may be beneficial in creating a ketogenic diet that minimizes nutrient deficiencies.

Don’t be surprised if you find yourself parched while you’re on the keto diet. Excreting all that extra water will likely cause a spike in thirst—so make it a point to drink up, Mancinelli advises. There’s no hard and fast recommendation for how much water you should be having on a keto diet. But in general, aim to drink enough so your urine is clear or pale yellow. If it’s any darker, bump your intake.
Unlike conventional diets, the Mediterranean diet doesn't restrict you to a daily allotment of calories, fat, or sodium. Instead, it’s about what you’re eating, from heart-healthy unsaturated fats to satiating, high-fiber foods. Taking these ideals to heart, we’ve constructed a Mediterranean diet meal plan for beginners from breakfast to dinner. Our recipes maximize flavor and nutrition to create balanced and colorful plates that marry whole grains with vegetables, lean proteins, and more. On top of all of this deliciously nutritious eating, make sure to work physical activity into your day, especially if you have a desk job.
In fact, the FDA now allows olive oil labels to carry the claim that its monounsaturated fat can reduce heart disease risks -- with a few strings attached. The claim says that "limited and not conclusive scientific evidence" suggests that eating about 2 tablespoons of olive oil daily may reduce the risk of heart disease. To give this possible benefit, it adds, the olive oil must replace a similar amount of saturated fat in your diet -- and must not increase the total calories you eat in a day.
