I'm still a little confused on eating fats and losing fat?


It just seems counter-intuitive that eating a high percentage of your calories in oils/fats somehow makes your body prefer to utilize body fat as fuel. I guess I don’t get the science - but I’m still reading. I’m about 1/3rd through the Fung book. It seems that adding lot of dietary fat to your system would make it more immediately available for energy usage than body fat, but there must to be more to the story. Can someone give me a 25-words or less explanation on why adding dietary fat (carbs or no carbs) can still result in body fat being utilized by your body instead?

Fat contains Leptin. Leptin fluxes through the hypothalamus and tells you you are sated, so you stop eating. There is no short term fat storage like there is glycogen for carbs. Not eating carbs causes you to secrete glucagon instead of insulin, so dietary fat is burned instead of stored.

More like 50 words.


Thanks amwassil and 240lbfatloss (wow!) … Starting to make a little sense. I’ll read the beginner’s guide link too… thx.

Personally, I’ve found protein way more filling than fat. Give me a fat bomb, and I’ll eat 5 of them instead of one. Give me lean meats, and they fill me and keep me full longer than do high fat meats.

I think I love you :smiling_face_with_three_hearts:
You always glibly sum it up.

For me, it’s the fat-protein combination that is the most sating. Much better than either fat or protein by themselves.


Different contexts, differnet results.

Minimize insulin and hunger. Maximize fat for fuel.

No because with carbs it won’t be effective and you will lkely gain. Without carbs you will be using the fat for fuel some from what you eat (although fat can be extremely satiating so you may eat a bit less then your body will use stored fat.
If you are eating carbs then you won’t get into this state (ketosis).


Yes … for me, the fat is satiating more than anything else, but I only have it with proteins too. I don’t really want to eat fat alone (Mmmm… drink melted butter :frowning: ) :smiley:

I wouldn’t recommend fat alone but always with some protein…
These days I add little if any but have been on this ride for 3 1/2 years.
