First 62 (kilos I assume) is not heavy! How tall are you?

It's common to see an initial rise in weight, and remember that weight loss is a long term process. You will not necessarily see improvements immediately.

Also, as realsomeone says, it's not a question of giving up food, it's more about eating the right food at the right time.

Also, try adding some weight exercises to your cardio workout. Studies have shown this accelerates weight loss.

If you're serious you should seek advice from a proper expert. From my experience "friends at the gym" rarely know what they're talking about and often give bad advice.
