Everybody is different so advice varies. For instance, some people do very well with carbs and grains. Other people's bodies scavenge every carb and store it as fat so a high fiber, high fat diet works better for them since fat is satiating and a source of energy, Contrary to popular opinion fat does not make you fat unless it is combined with carbs, like a hamburger bun, fries and large Coke. Then again this only applies to good fats like salmon, sardines, olive oil and grass-fed meat, not the rancid vegetable oil that are pushed on us today - they actually cause allergy problems that contribute to weight gain. The 350 pound lady is starving because her system stored all the carbs she ate - your body needs about a teaspoon of sugar in its system to run and she doesn't have enough in her system to run her body.
Good fats moderate a lot of metabolism problems for a certain groups of people. Our whole food industry is based on selling carbs. Try to buy food that aren't carbed up - it isn't easy. No wonder we have a weight problem in this country. Hungry? Try cutting carbs way back, increasing fiber and good fats - don't forget potatoes, carrots and most fall crops in general tend to be high carb foods so eat salads, cabbage and leafy greens with olive oil and vinegar dressing, for instance. Carb addiction is real so give your diet change some time. Oh yeah, stay away from processed foods - they contribute to weight gain too. Again, this may not apply to you in the least, but forget the old carbs in, carbs burned shit. It simply doesn't apply to some people.
