Losing it in 60 weeks (14 months) may seem amazing but it works out to 1.45kg per week which isn't that amazing really. Admittedly a few of those weeks were very good but some weeks weren't good at all. Indeed towards the end of my journey (last two months) I had some weeks where I lost little, or nothing...or worse - gained slightly!
But never were the loses of the order that you see on The Biggest Loser. So take heart with your 0.3kg loss...from little things - big things grow (down!).
As for the question about weekly or daily weighing in...
Many experts recommend that you only weigh yourself once a week (and a few believe that it should be monthly!).
The reason for that is daily weighing can be very discouraging because body weight can naturally fluctuate greatly each day.
To find that you've gained on the scales after putting in a huge effort can stop the unwary in their tracks and cause them to give up.
So why do people weigh daily?
There are many advantages to weighing daily so long as you understand that one or two days of weighing doesn't give you the whole picture.
Daily weighing is about developing a long term understanding of how your body works.
Your body goes through cycles.
Understanding those cycles greatly helps you get a grip on what to do and how your body operates and deals with food and exercise.
For example, if you have exerted yourself in exercise (feeling the pain in your muscles next day)...you will find that next morning's weigh in will probably be a gain...but this is a good gain
...because fluid is being retained in order to make muscle (which weighs more than fat in any case) and in the long term that muscle will burn more calories for you.
A survey taken of people who have lost lots of weigh and kept it off for over a year shows that one of the common factors in these people is that they weigh themselves DAILY.
I weigh myself daily and I find that not only does it help me understand my body but also it keeps me motivated (so long as I keep the daily number in perspective) and keeps a short leash on any blow outs (which means it keeps me accountable daily).
Best of wishes on that 10km run!...that should work off that dinner!
