Wise Merton has spoken simple truths...again!
Yes, instead of thinking about what you can't eat, think about what you CAN...apples (yum), bananas (yum on Special K), raspberries (double yum), carrots, pears, fresh lettuce from the garden. I swear that good things happen when one eats an apple a day.
And WATER--DRINK alot of water every day. Eight big, tall glasses per day. That will help.
It took years for the flab to gather; it'll take more than 6 weeks to get it off. Try walking, as long as your knees can handle it, and keep biking. You're getting stronger, healthier, and fitter! Don't stop now.
