You lose weight by eating less calories than your body uses.

Not entirely. Try eating 2,000 calories of pasta versus 2,000 calories of chicken. It'll do immensely different things to your body.

IF and keto are valid. Liquid diet is nutty. keto isn't exactly "eat lots of fat" -- it's avoiding > 30-60g carbs per day (and honestly, mostly sugars. carbs with fiber delivery (e.g. vegetables and limited fruits) are okay) while seeking out, but not adding "lots," of complementary fat (like avoiding fat free things because fat free just means "we added more sugar to compensate for removing fat").

If you have a limited memory capacity, just remember: fat doesn't make you fat. Your body turns sugar and things that metabolize into sugar (carbs, breads, pastas, rice) into fat. Your body doesn't take what you eat and just glue it inside of you. Food is like the input of a program generating very specific outputs. You can't feed the function "Add two numbers" 1 and 1 and end up with anything but 2. You (probably[1]) can't feed yourself carbs and carbs and carbs and end up with anything but lardass.

[1]: Though, people are different. We have basic guidelines, but a lot is still genetics. I know people who basically live off pasta, chocolate, and smoothies and still weigh 130 pounds without workout out significantly.



> fat doesn't make you fat

True, and it's why the low fat (== high sugar) marketing has done nothing to curb the obesity trends.

> Your body turns sugar and things that metabolize into sugar (carbs, breads, pastas, rice) into fat.

True. Keep in mind that (most) excess amino acids also get converted to carbs, and then to fat.


No, this is a very underused mechanism in humans. Highly active in lab rats though. Which led to this confusion. http://www.ncbi.nlm.nih.gov/pubmed/3799507 500g Carbs overfeeding > <10g Fat synthesized
