Carbohydrates ("carbs"). Despite what you may have heard, these are not evil. They are a necessary source of energy for your body. The problem is that people over-consume certain sources of carbohydrates, most notably simple sugars from soda and candy, and starches from white bread. If you have to cut down on one macronutrient, cut down on carbohydrates. People in Western cultures consume far too many carbohydrates on average.
Proteins. These are necessary for your body to maintain its muscles, repair damage to them, and generally hold itself together. Most people get enough protein, though an intense exercise program may call for eating more for optimal results. If you cannot manage to take enough protein into your diet, protein powder may be the key. Optimum Nutrition is a well-recommended powder.
Fats. Fats are not evil, either. Eating dietary fat does not mean that body fat will instantly appear; your body doesn't work that way. Fats perform a variety of necessary functions. The problem is that people over-consume saturated fats and trans fats, which raise LDL ("bad") cholesterol and lower HDL ("good") cholesterol, and under-consume healthy fats like monounsaturated fats (found in high concentrations in olive oil and canola oil) and Omega-3 fatty acids (found in fish, flax seed oil and other sources). Fats also have more calories ounce-for-ounce than carbohydrates and proteins, making very high fat foods astoundingly calorie-dense.
