I think the larger question is why we are seeing such a sudden rash of anti-keto stories. So many of them quote no experts sources and do not provide citations for their claims. Skeptics with little acquaintance with the diet are quoted exclusively instead. From a journalistic perspective, this lack of balance of viewpoints and the failure to back up claims with evidence falls below basic reporting standards. Offenders on this list include even the Harvard School of Public Health, which recently published more than one unsourced, one-sided article on the keto diet (This is in addition to the Lancet Public Health article cited above, by Harvard researchers, which suggests that a low-carb diet kills you). These stories could reflect lazy reporting or they could very well be scare tactics to steer people away from the keto diet. Why would reporters or scientists at Harvard be doing such a thing? That’s material for another post. Stay tuned.
One review, published in April 2016 in The American Journal of Medicine, looked at five research trials on overweight and obese people and found that after one year those who followed a Mediterranean diet lost as much as 11 pounds (lbs) more than low-fat eaters. (6) (They lost between 9 and 22 lbs total and kept it off for a year.) But that same study found similar weight loss in other diets, like low-carb diets and the American Diabetes Association diet. The results suggest, the researchers say, that “there is no ideal diet for achieving sustained weight loss in overweight or obese individuals.”
The DASH diet is especially recommended for people with hypertension (high blood pressure) or prehypertension. The DASH diet eating plan has been proven to lower blood pressure in studies sponsored by the National Institutes of Health (Dietary Approaches to Stop Hypertension). In addition to being a low salt (or low sodium) plan, the DASH diet provides additional benefits to reduce blood pressure. It is based on an eating plan rich in fruits and vegetables, and low-fat or non-fat dairy, with whole grains. It is a high fiber, low to moderate fat diet, rich in potasium, calcium, and magnesium. The full DASH diet plan is shown here. The DASH diet is a healthy plan, designed for the whole family. New research continues to show additional health benefits of the plan.
When your body burns its stores of fat, it can be hard on your kidneys. And starting a ketogenic diet -- or going back to a normal diet afterward -- can be tricky if you’re obese because of other health issues you’re likely to have, like diabetes, a heart condition, or high blood pressure. If you have any of these conditions, make diet changes slowly and only with the guidance of your doctor.
Because some cancer cells are inefficient in processing ketone bodies for energy, the ketogenic diet has also been suggested as a treatment for cancer. A 2018 review looked at the evidence from preclinical and clinical studies of ketogenic diets in cancer therapy. The clinical studies in humans are typically very small, with some providing weak evidence for anti-tumour effect, particularly for glioblastoma, but in other cancers and studies, no anti-tumour effect was seen. Taken together, results from preclinical studies, albeit sometimes contradictory, tend to support an anti-tumor effect rather than a pro-tumor effect of the KD for most solid cancers.
The first meta-analysis worth noting collected the data from 10 randomized trials comprising 1376 participants in total.  After analyzing the research, a key relationship emerged between dietary carbs and blood sugar levels. In short, the researchers described their finding thus: “the greater the carbohydrate restriction, the greater glucose lowering…” 
Participants were recruited from the Durham Veterans Affairs Medical Center (VAMC) outpatient clinics. Inclusion criteria were age 35–75 years; body mass index (BMI) >25 kg/m2; and fasting serum glucose >125 mg/dL or hemoglobin A1c >6.5% without medications, or treatment with oral hypoglycemic agents (OHA) and/or insulin. Exclusion criteria were evidence of renal insufficiency, liver disease, or unstable cardiovascular disease by history, physical examination, and laboratory tests. All participants provided written informed consent approved by the institutional review board. No monetary incentives were provided.
“Just because the scale isn’t moving, doesn’t mean that you are making zero progress toward your fitness goals and dream body,” explains Mike Roussell, PhD, co-founder of Neutein, a dietary supplement meant to improve memory and performance. “It’s easy to think you’ve hit a plateau when you don’t see additional weight loss on the scale, but that’s not always truly the case."
This was simply the best response to this article. The doctor who wrote it has no idea of the life changing benefits of keto. Bravo to you for speaking up. Congratulations on reversing your diabetes. I dont have diabetes and am not obese but I switched to keto to live a longer healthier life. I’ve never felt better. Must mention that I am 32. I want to prevent disease. Let the food be the medicine.
If you’re looking to get a jump start on your health and fitness goals this year, you may be thinking about trying the ketogenic diet. Maybe you’ve heard the phrase before — it’s a huge diet buzzword — but aren’t sure what it means. Here’s a primer: The ketogenic diet is an eating plan that drives your body into ketosis, a state where the body uses fat as a primary fuel source (instead of carbohydrates), says Stacey Mattinson, RDN, who is based in Austin, Texas.
