what they say is true. Eat the right food and exercise and you will lose weight.
I have done the 12 week challenge and it works. It may take a little longer ,but it works.
Started at 13 st13lb and today weigh 11 st. Did not like running so got a new bike and got on it. Started at 5 miles a day for 5 days a week. And now do a 100miles a week. But you must have rest Days. And do 15 mins of strength exercise a day.
Will not say it easy, but you will enjoy it.
Kind Regards Phil
