Many guys believe the bigger you are the better you will look. That isn't necessary always true. You can be on the leaner side and be completely shredded. If this is the case you will look grat on the beach. A guy who is bigger may be lacking a few stiations or cuts that you have. That would make your body more sculpted and therefore the more attractive physique.

However, you don't want to look anerexic or undernourished because that is really unattractive to the opposite sex. Girls love the whole greek god "perfection" look but they rather have a bigger, less cut guy than a kid who is to lean to the point where he looks like he belongs in National Geographic Magazine regarding starvation in a 3rd World country. It is best to just use your judgement and if you feel you are always hungry and are feeling weak do not be afraid to eat more but make sure you eat healthy with good nutrient, dense food.
