Some previous studies have suggested that very-low-calorie ketogenic (VLCK) diets may be effective tools to manage overweight and obesity (10, 11, 13). VLCK diets are a nutritional intervention that emulate fasting by restricting carbohydrates and fat with a relative increase in protein intake (6). The increased protein content may be partially responsible for the muscle mass preservation (12–14). Importantly, the weight-reducing action of these diets is rapid, and despite the fact that the ketosis state lasts only 60 to 90 days at the start of treatment, the weight reduction remains for up to 2 years (13). Therefore, VLCK diets operate by potent mechanisms to induce weight loss, and various body compartments might be altered. To the best of our knowledge, no studies have exhaustively assessed the changes in body composition associated with this type of diet, and variations in muscle strength have been only assessed in athletes (15).
Positive science on ketosis coupled with personal successes passed by word-of-mouth have driven more people to explore the ketogenic diet, says Volek. More recently, the keto diet hints at having a promising therapeutic role in cancer, Alzheimer’s, Parkinson’s and polycystic ovary syndrome (PCOS). Research is still early in many areas, but Volek suspects there will more definitive answers on the wider scope of the diet’s benefits within the next decade.
“That means you’ll eat avocado, coconut oil, meat, and cream of coconut, olives, and olive oil, animal fats like bacon or chicken fat, butter, fatty cuts of meat, fatty fish like salmon and sardines, as well as nuts and seeds,” Mancinelli says. Dairy is allowed on keto, she adds, but it has to be heavy cream. Milk, even full-fat, isn’t keto-approved.
“I recommend LCHF nutrition to all my patients to shift their metabolism to a more beneficial state. This nutrition is often enough to reverse diseases like obesity, diabetes and fatty liver disease, improving the health and quality of life of my patients. In my experience, other medical interventions also become much more efficacious. I recommend the Diet Doctor website, due to its panel of experts, to all my patients to make their transition easier.”
I did Atkins way back and successfully lost 40 lbs and also my gallbladder. Today, I love being in ketosis. (Down 35 lbs so far). There is a learning curve, for sure, and yes, I “fell off the wagon” for a time (long enough to gain a couple pounds back and feel hungry all the time and lethargic) but I am now back in ketosis & love the mental clarity, the energy, weightloss & best of all, not being hungry all the time!
I was a Corpsman (not a corpse-man as some recent somewhat fanatical president would say), and I can tell you many stories of Marines and Sailors who maintained restrictive diets (aka picky eaters). Most obvious was lack of sustaining energy (hypoglycemia) at mile 15 (with 80lbs of gear including a 6.5lb rifle and 200 rnds of ammo, etc.) and depletion of essential vitamins, electrolyte imbalance. They were always the first to collapse and have to hear me scold “see I told you so.” An IV of D5W usually does the trick (D is for dextrose, OMG!)
