Regarding the article posted about "high protein, high fat leads to less longevity." Low carb diets are
NOT high protein. They're high fat. Protein intake should stay consistent whether you're doing high carb or high fat. The only things that change on LCHF are your carb and fat intakes. No one that advocates LCHF/paleo/primal, etc. will ever claim that anyone should eat a high protein diet. That's one of my biggest pet peeves about the media. They've gotten it into our heads that all of those diets entail eating lots of meat. I was suckered by it too. I failed at LCHF 3 times before reading somewhere that LCHF does not entail high protein. It was only after learning that, and making adjustments, that I was able to successfully go LCHF.
Also, with all the discussion if LCHF, I'm surprised no one has mentioned ketosis. That is, after all, the entire goal of a LCHF diet.
For all of you that have felt like crap on LCHF, it's most likely because you didn't give your body enough time to adapt to fat metabolism.
It took me about 3 days to get into ketosis. It took about a month before I wasn't hungry all the time. This is because it can take a while for your body to adapt to fat as its primary fuel source.
If anyone is interested in some great info on ketosis/LCHF, look up Dr. Peter Attia.
This is his website:

This is a VERY informative video of one of his presentations:

In the video, he explains everything that's going on biochemistry-wise, which really helps to understand why ketosis works.
I've lost 25lbs in the last 2 months, my blood pressure went from 152/101 to 128/82, and my cholesterol and triglycerides have improved. I don't remember the exact numbers, but I am going back for more bloodwork in 2 months. My doctor is "worried" about my diet, even though she had all the numbers on the screen in front of her. I've been eating about 70-80% fat, with no vitamin deficiencies.
On a side note, I've also been doing intermittent fasting. I didn't plan on this, but after my body became fat-adapted, I was no longer hungry throughout the day. I still eat about 2,500-3,000 calories a day, but this no happens in just one meal in the evening. Works out great with school as well. There are VERY limited options for LCHF n campus, and too much temptation otherwise. This just worked out to allow me to not fall into the trap of eating on campus because my blood sugar has dropped and I'm hungry.
