Kiwi reporter plans to lose weight on pie and beer diet

Can you lose weight with a diet of pies and beer?
One Newshub reporter has vowed to spend the next four weeks only eating four pies a day, or alternatively, three pies and three beers a day.
The idea of the experiment is to prove there's no special trick to dieting and all that matters is putting in less energy to your body than you use during the day and you will lose weight.
For breakfast, lunch and dinner I'll be eating pies only and, on a Friday, I can exchange one pie for three beers, which has a similar amount of calories.
Women need less calories than men, who need 2500 calories a day. The pie and beer diet is only 1600 calories a day - two-thirds of what a man needs, which means there will be weight loss.
