The ketogenic diet may offer hope to people with type 2 diabetes who have difficulty controlling their symptoms. Not only do many people feel better with fewer diabetic symptoms, but they may also be less dependent on medications. Still, not everyone has success on this diet. Some may find the restrictions too difficult to follow over the long term. Yo-yo dieting can be dangerous for diabetes, so you should only start the ketogenic diet if you’re sure you can commit to it. A plant-based diet may be more beneficial for you both short- and long-term, so input from your dietitian and doctor can help guide your diet choice.
During the 1920s and 1930s, when the only anticonvulsant drugs were the sedative bromides (discovered 1857) and phenobarbital (1912), the ketogenic diet was widely used and studied. This changed in 1938 when H. Houston Merritt, Jr. and Tracy Putnam discovered phenytoin (Dilantin), and the focus of research shifted to discovering new drugs. With the introduction of sodium valproate in the 1970s, drugs were available to neurologists that were effective across a broad range of epileptic syndromes and seizure types. The use of the ketogenic diet, by this time restricted to difficult cases such as Lennox–Gastaut syndrome, declined further.
If you ate a hearty breakfast, you won’t be hungry until lunch. It’s best to brown-bag it because you can control the ingredients and portions, but if you eat out, look for grilled fish and salad as a menu option. Don’t eat at your desk while writing a report, but go to the park with a friend or join your co-workers in the lunch room. Bringing leftovers is also a good lunch option.
Also, if you listen to Dr Bernstein talk about his childhood (he is well into his 80’s), the “original” recommended diet was only ketogenic in the sense that it was high-carb and caused keto-acidosis, which he describes as almost killing him as a teenager. He still considers the ADA recommendations as ketogenic for this reason (you only have to listen to him a short time to hear him railing against the ADA).
Those issues can be part of what's known as the “keto flu,” Warren says. Other side effects of the keto diet, all of which are tied to carb withdrawal, can include lightheadedness, nausea, mental fog, cramps, and headaches, in addition to tiredness. Luckily, the keto flu doesn't usually last more than a week—which is coincidentally about when people start to see the number on the scale go down, says Warren.
On a ketogenic diet, your entire body switches its fuel supply to run mostly on fat, burning fat 24-7. When insulin levels become very low, fat burning can increase dramatically. It becomes easier to access your fat stores to burn them off. This is great if you’re trying to lose weight, but there are also other less obvious benefits, such as less hunger and a steady supply of energy. This may help keep you alert and focused.
