When I was in college I dropped over 50lbs. It was easy...run 10km in the morning and 10km at night. Have some chips and beer. Repeat as needed. Now that I'm older most of us will need to accept that we can't burn 2000 calories a day. The biggest things I noticed when helping my parents lose weight was intake and meal sizes. The post above about calories in "a single plate" is certainly true in many aspects. For example don't have 10 wings. Have 5 plus a side. It is not easy many will tell you that. My family, European, was always about making more food. For a family of four we would have 6 to 8 steaks. Save the rest right...nope. we would nibble until its gone. You will be surprised but meal planning and portion control will be one of the biggest contributors. Unless you can run triathlons every weekend.
