Take a snapshot of yourself every day or every other day (in an identical position if possible) dressed in a bathing suit... and judge the impact of your diet on your body. Keep these photos to yourself at first. Don't show them to anyone - you don't want people's remarks to put you off! Once the results are visible, you can start telling your loved ones about your new regime. You could then think about creating a little video or animation photo display of all your pics! See the results! You'll be so proud to share your photos with your loved ones! They'll be so surprised at how much weight you've lost! Indeed, it'll be difficult for you to see the progress you make on a day-to-day basis for yourself! But friends and relatives will be able to see it more! They're bound to be impressed and they'll definitely encourage you in the pursuit of your final goal.
