There’s this concept floating around some keto circles that A) insulin causes fat storage B) fat doesn’t spike insulin so C) if you eat low carb/low protein and high fat, the fat doesn’t get stored. A is true, B is true, but you always have basal insulin (unless you’re type 1 diabetic) so excess energy you eat of any sort will get stored eventually (except in some cases). Our bodies are shaped by millions of years of evolutionary pressure to be efficient and not waste precious resources.
Weight loss is a function of calorie intake vs daily energy needs. Weight gain is quite easy with fat, because it is very energy dense for its size and weight. The IK model is setup to relieve you of those worries. Review the 30g thread, listen to the newbie video, and enjoy meat and green veggies.
