"Am just an ordinary 63year old lady! Yes, with Arthritis, Hypertension, low energy, aches and pains etc, working to combat the ravages of the Aging process through lifestyle modification. I will guide you on how in being diligent, by the special grace of God, I dropped from a size 16 to a size 10, in 2 years! BIG QUESTION- WHEN DOES THE AGING PROCESS BEGIN?? It begins from age 21. And if you are not leading a healthy lifestyle, it accelerates and you achieve degenerative changes prematurely!! So many sudden deaths these days, so many belly fat men and women with PSEUDO- PREGNANCY ( it's a time bomb!! )

Easy does it. Set a one year target. It took long for the luggage to accumulate. Combine moderate/right eating with sustained 30minutes to 1hr Excercise , at least 3 times a week. Nothing, excessive, sustained healthy lifestyle over a year, and you start seeing benefit! Combine with drinking 60cl of Alkaline water every 1-2hrs and at least 6-8hrs sleep a day and one hour to 2 hrs in prayer, reading the word and meditation daily! That works out to 11hrs a day, leaving 13 hrs for you to work plus accommodate other exigencies. Bless you all.
