Fuck me - so much bollocks being spoken here!

What's the difference between "filling up on protein" rather than carbs?
Why exactly would eating 500 calories of protein make you less likely to put on weight than 500 calories of carbs?
When you eat carbs, this is sugar, as far as your digestive system is concerned. The glucose in your blood stream causes insulin to be released, to sweep the sugar out of your blood stream. Some of this goes to provide immediate energy needs, some is stored for later energy needs, in the form of glycogen (stored in your liver and muscles), and the excess is laid down as fat.
When you eat protein, although your body produces some insulin, it's at a much lower level, so you don't lay it down as fat.
When you eat fat, your body doesn't produce any insulin so it isn't laid down as fat.
Ergo, if you fill up on carbs you are more likely to lay down fat.
If you fill up on protein you are much less likely to lay down fat.
If you fill up on fat you are even less likely to lay down fat.

micah as I understand it carbs which aren't burnt off or used by the body are stored as fat whereas protein isn't. Carbs are basically sugar. There's some scientific thinking behind it all but to be honest, low carbing is bloody boring and restrictive
There's a lot of scientific thinking about it! You didn't need carbs when you started training, if you were properly fat-adapted - if you were fat-adapted, which you would have been if you'd been low carbing for a while, then your body would have used fat as a source of energy rather than carbs. Your body can only store a certain amount of carbs, and it's quickly exhausted when you're doing an endurance sport like a marathon - this is why people talk about 'hitting the wall' when they're running, or 'bonking' when they're cycling. If you are fat adapted, you have plenty of fat to deal with your energy needs and this won't happen. Read The Art and Science of Low Carbohydrate Performance for more scientific evidence to support this.

I am so fed up of hearing from kook nutritionists who make money from the carb is bad mantra. The number of people who buy into it is ridiculous. Carbs aren't fattening - fat is fattening. As it is more calorie dense per gram it takes longer for fat to fill you up. Ask anyone with a degree in nutrition about this and I am 95% sure they will agree with me
People 'buy into it' because the science behind it is absolutely true. It's not about kook nutritionists. Carbs are absolutely fattening, for the reasons I've explained earlier on. Fat isn't.^

The person who invented the Atkin's diet died from his own diet plan. Carbs are good.
No, he slipped on the ice in New York and died from his head injury
