I have always exercised and ‘tried’ to eat right (I try to have good main meals but I also eat junky type snacks) and just in this last week I have really put my mind to it and actively tried to eat very healthily and amped up the exercise.
So basically I started one week ago with this diet.

I go running/walking every day for an hour. Doing interval training as well as running up very steep hills in my neighborhood. The rest of the day my exercise is very minimal and I am seated for a majority of the time.

I no longer snack an if I do it is on a few rice crackers or fruit like peaches or a banana.
For breakfast I have a smoothy made from strawberry,banana and skim milk however I am often in a rush and if I don’t have time to make it I will have a popper type drink made from flavored soy milk (200cal).
For lunch I have a salad sandwich made with wholemeal bread, light olive oil spread instead of margarine, one slice of cheese and salads like lettuce/tomato/beetroot/cucumber. I have no dressings or mayonnaise with this.

At dinner I have been having just salad with maybe some grilled or BBQ chicken though only about half a breast worth. Tonight I am planning to mix up up a bit and instead have an omlette made with vegetables and egg white.

I usually have one after dinner mint at night because it stops me from feeling like snacking.

I never feel starved during the day from this diet although I sometimes get a little bit hungry before my meals.

I weighed myself yesterday at day 6 and I was down 1.4kg (about 3 pounds) from my starting weight. However, I did what dieters are not supposed to do and weighed myself again today and I am 0.2kg (1/2 pound) heavier than my STARTING weight. So all this work an I have only gained.

Is this normal? What am I doing wring with all this? I know it is ideal to eat six small meals a day but I find when I do this I am more inclined to snack on rubbish so I try to do the 3 meals.

What should I do?
