Coach Jack’s Rant of the Day
The idea that fat consumption can slow or stall weight loss.
I’ve seen this Meme more times than I can count. It is the absolute opposite of the whole idea of Ketogenic diets.
It isn’t about the calories and that is where he is wrong. He is correct that you can over consume fat but it has nothing to do with calories because the body doesn’t know what a calorie is and it is so very hard to do.
Fat can be over consumed to the detriment of weight loss but only in the respect of energy balance. If your insulin is low energy will flow unabated from cells. That energy is fat if you’re ketogenic. If fat is coming out of cells and saturates the body with the energy it needs to operate, any incoming fat will be either converted to blood ketones and stored, wasted as heat energy by brown adipose, wasted in the urine as ketones or in the breath as ketones. The issue of it slowing weight loss only comes into effect if you consume so much plate fat that your blood ketones rise to a level that is about 7 times higher than the average. About 7.0 mmol/L is where I suspect that insulin kicks in to lower them since the highest levels I have ever seen was 7.6 mmol/L and it was followed quickly by a subsequent drop in both ketones and glucose levels. This is indicative of an insulin response. I have only seen this level in 3-4 people and it took a massive amount of fat to get them there. Much more than the average person could even tolerate. If insulin kicks in, wether from ketones of glucose, weight loss stops.
This is the only way Dr. Westman is accurate in his statement.
Calories in and calories out is the essence of what has failed us in weight loss for the last 50 years. It has never worked yet even the “experts” in the ketogenic community still push this idea. Putting a pretty bow on caloric restriction is still putting a bow on a turd. No matter how fancy you dress it up it is still a turd.
