Hi all,
I am relatively slim already but am looking to lose up to 5kg ideally.
I have been swimming three times a week for three weeks so far (800m at a quick pace) and walk the dogs for a total of 90 minutes each day.
I thought I had been eating well, but I have actually gained 1kg since the last time I weighed myself. 
Today's meals have been:
Breakfast: quarter cup of oats soaked in water and cooked with a splash of milk; chopped banana on top
Snack: plain Kettle chips 
Lunch: sandwich and lots of fruit: berries, kiwi and a mandarin
Dinner: curried sausages with rice
I'm just not sure where I'm going wrong. I have, for the most part, cut out sugars and refined foods (kettle chips is an anomaly as they aren't normally in the house). I eat a lot of fruit; more than the average person, but I can't imagine that it would cause me to gain weight?
