I'm female and I'm quite skinny with a round fat face that I'd love to get rid of , I'm thinking about only drinking water and one meal. The meal would be dinner at 4pm everyday and would consist of ; chicken, pasta, rice, potatoes, chips, meat..... I'd have lots and lots of water throughout the day and sometimes have lemon slices in the water, how does this sound?
