Both Dr. Stephen Phinney and Prof. Jeff Volek, who defined the term “nutritional ketosis,” have said that the 0.5 reading is somewhat arbitrary. It’s just the level at which they felt they began to see benefits of the ketogenic way of eating.
The real point of the diet, in my opinion, is to lower glucose intake and lower serum insulin. The presence of ketones is an easily-measured effect of the lowered insulin and glucose. (Note that there is at present no way to measure serum insulin, except by means of a laboratory test.) And the fat loss that often accompanies the diet is a much-prized side-effect, because so many of us got fat eating a high-carbohydrate, low-fat diet.
So my question would be what the Eliquis is doing to your serum glucose and your serum insulin. Even if all the weight you are gaining is from storing fat, it still might not be a problem where your metabolic health is concerned. Dr. Robert Lustig makes this point: about 20% of the obese are pefectly healthy, just overweight. It was for them that the medical term “metabolically healthy obese” was coined. The converse is the significant percentage of lean people with metabolic disease, described as “thin on the outside, fat on the inside”: (TOFI) in the medical literature. And there are actually more TOFI’s out there than MHO’s. .
Granted, if you are eating a ketogenic diet solely to shed excess fat, seeing the number on the scale go up, even when it’s from additional muscle, not from additional fat, can be grounds for freaking out. And if it’s a medication that is supposed to be helping you, it is normal to feel betrayed. Perhaps there is a different anti-coagulant that you might take, that wouldn’t make you fatter?
Of course, all drugs have potential risks and benefits. My mother’s cardiologist and I had a number of go-rounds about her Eliquis prescription. The doctor was quite frank that from his point of view, it was a tough choice: whether to let the patient die of a heart attack, or to prescribe a drug that would prevent the heart attack by killing the patient from a brain haemorrhage instead. Either way, he was risking a lawsuit. We never did decide what to do, before Mom had a fatal fall instead. And for the record, I would never have sued him for doing his best, no matter the outcome.
