Sometimes I go the odd packet of chips - I am not good but I will not worry about it as long as my weight stays between 70 & 80 kg. If I do go above 80kg I just force myself to stay above 30km/h on the shared path all the time on the way home and watch the snacks I eat. Presto 3 weeks later I am back where I should be - keep going one more week because fast is fun and then usually stuff up again.
It also only seems to happen this time of the year.
