Different foods are going to affect your insulin levels differently, which directly controls whether your body is storing fat or burning fat. I don't eat sugar and keep my insulin levels low, so my body is always in fat burning mode. A month ago I did a 5 day hike through the Trinity Alps, eating about 1000 to 1500 calories a day. Not once was I actually hungry.
