If you can't pick it, grow it, or kill it, don't eat it. LC's are low cal, but they're usually packed with sodium\salt. If you choose to have those, a good rule of thumb is to make sure the ratio of fat calories to calories on the label is below 1/3 e.g. The glazed chicken has 45 calories from fat, but an overall total of 245 calories, ...so it's fine from a fat content standpoint, but the sodium content can make you crave more food than you need. Nutrition (imho) is more important than counting calories, but you also don't want your body to go into starvation mode (starving can cause your body to store anything you consume straight to your fat stores and rob your muscles of protein) so paying attention to calories can help there. There are several calculators (http://www.freedieting.com/tools/calorie_calculator.htm) on the internet for what you should consume calorically in a day, and I'd recommend a deficit of no more than 600 calories from your recommended intake for fat loss. I'm 6' and 205, so my maintenance calorie recommendation is 2700 a day, with 2250 as the recommended for fat loss. That's a steady approach to fat loss from the caloric side. A good structure to follow is to reduce carbs from your diet, increase your protein and good fat content. The carbs you do eat, consume in the morning or at lunch. Decrease carb intake during the day, and increase protein intake over the day. Good carbs in order of best descending: Green leafy vegetables, fibrous vegetables, fruits, red potatoes, brown rice. Eat leaner proteins: chicken, turkey, fish, beans.
Final word on diets...you need 2. One as a plan to get you to the weight you desire. The second and far more important one is the maintenance diet eating plan to follow once you've achieved your weight. The DASH eating plan is a good example, or the perfect health diet.
