If you follow the PUFA debate, you’ll see over and over again people saying that we can combine carbs and saturated fat and get a satiating effect. For instance, croissants, high butter breads like biscuits, French fries fried in tallow, etc., and get a satiating effect. As one example, “The French eat carbs and high fat yet are thin”. Another: “We ate carbs in the 1940s/1950s/1960s, yet were thin.” (The latter is an argument for PUFAs causing obesity, but it implies we were eating carbs + high saturated fat, and that was good.) A final example: “McDonalds used to use tallow on their fries, and we were all thin.”
I have tried this multiple times:
- Real, homemade croissants, with extra butter packed on each one
- French fries made in tallow I made myself from suet (high in saturated fat)
- Biscuits + more butter on each one
With each one of these, I was able to eat and eat and eat…with no satiety effect I could discern. I had to force myself each time to stop eating. (Though for the french fries, my wife and I stopped…because we ate the several pounds of fries I made. All of them. And that was with burgers.)
For me, the idea of carbs + saturated fat = satiety is not true. It’s the opposite, in fact.
Furthermore, I’ve tried high fat/ow carb multiple times. Each time, I found no satiety from high fat. In fact, I find the most satiety from high protein, low fat. And I lose the most weight with that.
I’ll give you an example. I gained 20-25 pounds trying the croissant diet (though I used croissants only once, for (1) above). I then tried just higher fat by eating high fat yogurts, chocolate, cacao butter. While that was better, I was losing weight too slowly.
My diet now, to recover from the 20-25 pounds I gained from the croissant diet, is high protein, low fat. This has allowed me to get back into most of my 36 waist pants and some of my 34s. But it’s taken me almost 2 years to do this. (I have to say, I’ve also restarted some longer fasts, and these might help too.)
On the other hand, here’s someone who ate very high fat and lost weight:
I have not tried this exact same experiment, and not sure I could (the idea of starting out by eating fat…I can’t go there).
Personally, I’m leaning toward genetics. That is, my genetics “likes” higher protein, lower fat. Something like this:
Your thoughts? Is genetics a possibility? Or is fat + carbs always bad? Or does fat + carbs simply taste “too good” (yet another theory of obesity)?\
(Note: when I was testing the croissant diet, I often ate very high saturated fat meals in sweet potato, potato, spaghetti squash; it really didn’t taste that great, but I still gained weight.)
