Not necessarily. Ketogenesis is stimulated by glucagon and inhibited by insulin. But the key is the insulin/glucagon ratio, which determines whether the metabolic milieu is primarily anabolic or catabolic. Since we need both anabolism and catabolism to occur regularly, there are complex mechanisms regulating this.
Don’t chase ketones, chase metabolic health. Weight normalization is merely a side effect of metabolic health, anyway. The problems resulting from hyperglycaemia and hyperinsulinaemia are well-known:
advanced glycation end-products, sytemic inflammation, hypertension, increased blood coagulability leading to stroke and myocardial infarction, fatty liver disease, cognitive disability—to name just a few.
Still want those carbs?
These are not mutually exclusive. The real opposition is glycolysis versus fatty acid metabolism. The latter occurs only when carbohydrate intake drops low enough to lower the insulin/glucagon ratio. Gluconeogenesis is necessary when dietary carbohydrate drops, or we would keel over and die (literally; our red blood cells would starve to death, and the brain would then expire from oxygen deficiency). So gluconeogenesis occurs routinely whenever glucose intake (i.e. dietary carbohydrate) is too low to supply the need.
This is the same condition that makes ketogenesis and fatty acid metabolism necessary, since gluconeogenesis provides only enough glucose for those cells that absolutely need the glucose. During the fat-adaptation phase, our muscles limp along on ketone bodies, until they can re-ramp up the fatty acid pathway and start using it. Once fat-adapted, our muscles actually prefer to metabolize fatty acids, in preference to glucose and even ketone bodies, sparing the latter two for use by other organs. The brain does particularly well on ketone bodies, and as mentioned, red blood cells require glucose. Hence, ketosis and gluconeogenesis are partners; it is glucose metabolism that is the antagonist.
Given the ill-effects of hyperglycaemia and hyperinsulinaemia I mentioned earlier, I don’t really understand the reason for wanting to ingest any kind of quantity of carbohydrate—apart from addiction, of course. I fully understand that. But although I may still occasionally yield to my addiction, I fear carbohydrate more and more, the more I learn about nutrition. 
lol That just sounds funny to me
