Agree 100 percent.

And I'm living proof that it works.
Low Carb/High Fat/High Protein works
Low Fat/Moderate Protein/High Carb works
...most diets that people report success with (regardless of name) usually follow one of these two patterns.
High Fat & High Carb simultaneously is where most people get into trouble (sometimes referred to as the SAD diet "Standard American Diet"). ...and most of the foods people eat fall into that category (Pizza, Fast Food, etc...)
Vegan/Vegetarians will say "you're getting fat from all the fat" Atkins/Paleo will say "you're getting fat from all the carbs"
I've tested both diets on myself just to see what works and what doesn't.
I can carb up all I like provided that the meat I eat is all lean cuts of chicken and I don't gain any weight.
I can eat a bunch of fatty cuts of meat all I like as long as I keep the carbs under 50g per day and I don't gain weight.
However, if I eat the fatty cuts of meat, and eat high carb at the same time, I can gain 5-10 lbs in a week...as soon as I switch back to one of the other two approaches, the weight comes right back off in 4-5 days.
However, back 5-6 years ago when I needed to drop 40-50lbs...I had pretty good luck with the paleo model (basically 50% grass fed meats/50% green veggies). Dropped 40lbs and my cholesterol improved (despite what the vegans will tell you about how meat raises cholesterol levels)
Basically, I'm at the point now where I decide which pattern to follow based on what I'm trying to do at the time. If it's winter time and I'm just focusing on muscle building and strength, I'll go with the approach that has a little more carbs and a little less fat (as the carbs do help with higher intensity training). This time of year (pool season) when the focus is leaning out a bit and looking good with the shirt off, I'll keep the carbs lower.
