If you are pregnant or are nursing, you should not follow a Ketogenic diet. You will not receive enough of the recommended carbohydrates, vitamins and nutrients necessary for yourself and your growing baby on this diet. Your obstetrician will recommend how many carbohydrates you should consume per meal and for snacks during each phase of your pregnancy. They will likely refer you to a Certified Diabetes Educator for nutritional counseling as well. Please check out The Diabetes Council’s FAQ’ About Gestational Diabetes for all your gestational diabetes related questions.
Without peer-reviewed clinical trials, many of the benefits remain anecdotal. For instance, Weiss himself has been on a low-carb high-fat (though not strictly ketogenic) diet for more than six months, and claims he does feel much better. But he’s clear about what he knows and what he doesn’t. He’s lost weight and his borderline pre-diabetes is gone.
At the conclusion of the intervention, both groups had improved in all metrics but “these changes were more significant in subjects who were on the LCKD as compared with those on the LCD.” . As a result, the researchers supported the study outlined above and concluded that their “…study shows the beneficial effects of a ketogenic diet over the conventional LCD in obese diabetic subjects.” 
“The alkaline diet often has a focus on eating lots of fresh produce and unprocessed foods, which could be a good thing,” says Hultin. “However, keep in mind that this is not an evidence-based therapeutic diet. When people take it too far — for instance, drinking baking soda — or become too restrictive or obsessive over food choices, it can definitely turn negative.”
Like peanuts, lentils also contain genistein, but their weight loss powers don’t end there. In one four-week Spanish study, researchers found that eating a calorie-restricted diet that also included four weekly servings of legumes aided weight loss more effectively than an equivalent diet sans the pulses. Those who consumed the legume-rich diet also saw improvements in their “bad” LDL cholesterol levels and systolic blood pressure. Next time you’re cooking something starchy for dinner, consider eating fiber and protein-packed lentils instead.
Fish and seafood come next, eaten about twice a week. Poultry, eggs and dairy in the form of cheese and yogurt are eaten in moderate portions on a daily or weekly basis. For example, one review of research on Mediterranean eating suggests about four eggs a week. At the very top of the pyramid -- meaning you eat them only sparingly -- are red meat and sweets. Preferred beverages include water, as well as red wine, in moderation.
Speaking of things you find in the sea, oysters have also been shown to contribute to weight loss thanks to their impressive zinc content. One study found that obese people who consumed 30 milligrams of zinc per day—the equivalent of just six raw oysters—had lower BMIs, weighed less, and showed improvements in blood cholesterol levels. If oysters aren’t your thing, spinach, pumpkin seeds, and mushrooms are also excellent sources of zinc.
