First things first, I usually run 5-6.5km every second day, so Mon, Wed, Fri, Sun, Tue, Thu, Sat, Mon... etc, and I ran 11 kilometres on Sunday, and I was really tired and I told my colleague that I haven't missed running every other day since the 6th July, and that I haven't missed every 3rd day since I started exercising (mid-May), then he said that I should rest because the body actually loses weight faster when you take [longer] breaks every now and then, something to do with the body FIGHTING BACK against the 'routine' so you actually lose more, is this true?
