seed oils from a fat loss perspective aren't necessarily bad. still 9kcal/gram. if they don't provide the micronutrients and satiety you need, that's a different story.   if you have an underlying medical condition (i.e. hormone imbalance) you'll need medical guidance, but after correction, cico still applies. keto works at first for many because, if followed by the book: you cut the most prevalent comfort food: carbs filling up on mostly fats is tiresome each gram of carbs out reduces water weight but if difficult over time unless you become a keto zealot. hormone manipulation is tricky, can work very well in selected individuals for gain/lose weight (i.e. bodybuilders) and usually need individual tweaking and continual treatment (i.e. diabetic people).
