Calories do matter. If someone is eatin gin excess of 3,000 a day, they may have problems unless they are a large man (that olympic 18 year old swimmer eats 4500 a day). Others though will have appitite supressed to where they only eat around 600 for many days strait, and they start to feel poorly and weight loss does slow.

If you feel you are eating to many calories to get full, start adding fillers to your diet. I'm not talking bread or starches, but veggies can be amazingly filling for little calories. Others find by upping thier fat and lowering thier protien intake they feel full at a much lower calorie point.

All the people on boreds can do is say what works for them, and what they have seen work often in others. Most of the advise they throw out is just sugegstions of ways to try tweaking your plan to see if it works for you personally. If it doesn't work, then move on to the next step.
