There you go, Mo: "The Jesuit Way to Health and Fitness", c/o Fr. Hartigan! You could, of course, resist the call of the Iberian coast, and simply fast for a couple of weeks. I'll tell you what I did for ONE WEEK ONLY at Inglewood Health Hydro in Kintbury, near Hungerford in Berkshire. You need to do it preferably when you're not working, and certainly not with your driving schedule. Every day:
After rising: Glass of hot water with a slice of lemon. Drink when warm.
Elevenses: Glass of fruit juice. I had clear apple juice.
Lunch: Bowl of hot clear soup (such as consomme), or large glass of vegetable juice, such as V-8.
Teatime: Tea. No sugar, milk if desired. You can get away with 2-3 cups or mugs if you're really desperate!
Dinner: Same options as lunch.
Beddy-byes: Warmed water without the lemon. Try to hit the sack around 10pm so as to rest fully.
Throughout the day: plain water, but NOT - surprisingly - mineral water, because of its' generally high sodium content, which helps retain fluid, which you want to keep whooshing through your body, to carry away toxins.
Result: Lost 12lbs, felt exhilarated, went on holiday to Spain, lost loads more because I only wanted to eat 'good' food, and exercise more than before. Went back to work in Saudi, fasted for a month as above, working and exercising. Total loss within 3 months: 40lbs.
This was considered to be a fasting regime, and on the third day I got a banging headache and felt terribly tired. No problem - it's normal. It's an ideal time to spend quietly, not watching tv, perhaps reading, and to take some warm sea-salt baths, to draw out impurities through the skin. If you can prevail on Mrs Mo to give you some relaxing oil massages, all the better. I got massages, a mud bath, and a seaweed wrap at the spa, and felt fantastic - full of energy, when I left.
The 'effects' lasted about five years, when I developed asthma, stopped exercising, and increasingly stuffed myself with junk. Hence the bouncy castle look of today.
