Just eat as much real food as you can, and avoid junk food. It's ok to eat junk here and there, especially if you are an active runner, but just eating real food will keep you satisfied and overall healthy.
I agree that junk food is the major problem for most people, but it is CERTAINLY possible to gain fat and excess weight just eating "real food", especially if that is food is mega portions of beef (yes, even ultra yuppie grass fed organic kinds) that are not lean (high sat fat content), mega portions of nuts (very nutritious, but loaded with fat), and mega portions of carbs (whether it be potatoes, rice, or pasta). It certainly can happen.
And I meant to add in comment to the guy saying "Fat good, carbs bad...", that, for those that don't know it already, dietary fat tends to be less satiating and more likely to be stored as fat than carbs (carbs, especially whole grain/fiber rich ones are more satiating, and less likely to be stored as fat than fat). Yes, protein is more satiating and less likely to be stored as fat than both carbs and protein, however, most people get a lot of fat with their protein (whether it comes from cow, pig, tofu, or nuts). If you are truly eating lean protein, yes, this is a good way to fill up and not gain fat. However, most people don't really eat protein that is that lean, and end up getting a good amount of fat too, which defeats much of the good gained from the protein (as far it the meal not being stored as fat).
Now I have no problem with eating fat, I am simply saying it is misguided to state that eating as much protein and fat as you want will not lead to one becoming overweight, while carbs certainly will. The evidence absolutely doesn't support this position in most people over the long haul. For most people, overall calories plays the biggest role. And while yes, cutting carbs and fat in favor of truly lean protein might make you leaner, you will lose out in a lot of important micronutrients and fiber this way. And lastly, while it is still controversial, in animal models, and some short term human studies, there are still some concerns about the effect of medium to high protein diets on the kidneys. And a high fat /high protein diet, even if not excessively high in calories, has been shown to increase the plaque buildup and diminish arterial blood flow compared to a higher carb diet. Furthermore, several studies show that cutting carbs for more protein and fat LOWERS testosterone levels compared to the higher carb diet. Very lastly, if you are running a lot, by cutting carbs, you will potentially suffer poorer training recovery, which could lead to less intense and shorter workouts, i.e., burning less calories, and then you will rely on the less efficient protein and fat for energy, taking away protein that could have gone towards muscle re-synthesis.
Excessive sugar and soft drinks and candy and mega portions of refined/stripped grains are certainly bad for one and will lead to weight/fat gain. And yes, a fair amount of people are gluten insensitive or have celiacs. But to jump from there to "carbs... are .... bad for all people all of the time. Especially wheat. Fat (especially sat fat!!) and protein are all good. End of discussion" is truly dumb, and just not reflected by the research.
