Going by how you feel in response to diet changes doesn't necessarily work all that great. Eating loads of meat and under consuming sugar and starch, for example, will send catecholamine levels way up. This will have the short term affect of making you feel better. Inflammation will go down and you'll have more energy. This is the same effect that causes people to say they feel good on a fast. But once you clock up a year or two with elevated catecholamines your health will tank from the stress.
