Only way is to burn more calories than you consume
So here goes, you will lose 5lbs a month doing this and save some cash
1. Cut out alcohol every 2 weeks
2. Never eat after 6pm
3. Every other day miss out your last meal (5pm to 6pm) --- once you have lost the desired weight change this to every 3 days to maintain your weight
4. Do body weight circuits for 10 minutes every other night
..... If you can do these on your first go without being sick I'll send you £10 in the post

6. Rest one day a week
7 understand food is for energy not for pleasure
8. I missed this bit and it's the most important. You must reward yourself every week or month. Any money you save by not buying beer or food or some food you don't need save it in a piggy bank. At the end of the week or month spend on something you want ... Like a pair of batting gloves. Soon you will get a lot more satisfaction from this than you realise
