I just started two months ago, I thought I would be grumpy because I love a big breakfast in the morning, but now after skipping breakfast I'm less hungry at 11:30 than before. So sometimes I have breakfast at 12 and sometimes normal lunch. Losing a bit more than a kg a week even though I'm still drinking beer on weekends. Just can't believe how easy it is.
