Going to set myself little goals 2lbs in two weeks and 3 litres of water per day.
Outcome goals are great but focus on process SMART goals. What do you need to do to lose that 2 lb? Make them small, measurable, and with a deadline. Write them down and put them somewhere you see them often (and review often). Start with "I will.." For example,
I will not go food shopping while hungry. (This is what always dooms me!)
I will stand up and walk around during every other ad break during x, y, z tv shows. (I've heard of some people getting ripped doing push ups during ad breaks but that seems like a lot of work to me...)
I will stop eating second helpings at dinner. (Have you tried using smaller plates?)
I will have at least five healthy dinners this week (gives you some wiggle room).
These are some of the steps that may help you lose that 2 lb in two weeks and can be tackled (and achieved!) daily, hourly, weekly. Making huge changes usually doesn't stick, you need to figure out what are the smart choices that work within your current lifestyle. You're already ahead if you like to cook and eat healthy homemade meals!
If you didn't achieve one of your small goals, why not? What was the situation? What led you to choose the alternative? How can you make the smart choice next time this situation arises? Figure out what sets you down the wrong path, figure out what you can do to make the smart choice next time, then next time you'll be prepared with a plan for making that choice and you win!
Unfortunately, while exercise is fabulous (and keeps me sane) there is a lot of research showing that weight loss is really dependent on reducing caloric intake. Like PP said, portion size is critical. Don't eat with your eyes! Exercise may (more than likely) reduce risk of chronic disease (type II Diabetes, CVD, good for bones, hypertension, mental health, some types of cancer, all cause mortality etc...) but relying on exercise alone for weight loss may make it harder to achieve that weight loss. Exercise IS critical for maintaining weight loss.
Also agree with PP about wearing the uncomfortable jeans. There's some research on American caloric consumption during thanksgiving and there is a significant increase when people are wearing the elastic waistbands!
Hope this doesn't sound too preachy, my personal and professional lives revolve around this stuff so I eat, breath, and sleep this! Weight loss is HARD, there's just no short cut or easy way to get there. Except for surgery... and some of the research on that...
