Food for Thought

A new year, new resolutions, a new diet, a new you
Digg!
As you loosen your belt and renew your vows to cut back on second helpings, dispense with desserts, forego chocolate and hot chips and sign up at the gym, keep in mind that it’s better to be a full-time healthy eater, than a part-time ‘loser.’ Indeed, the biggest loser in the fastest time is possibly destined for the biggest weight regain.

[EXERCISE]

From high protein to low-fat, from eating right for your type to eating like a caveman, any calorie deficit (burning more calories than you eat) diet can help you lose weight. But the real name of the game is maintaining that weight loss for your long-term health and wellbeing including reducing your risk of heart disease and diabetes. It’s not a competition to be the biggest loser in the shortest time. It’s the challenge of converting your old eating and lifestyle patterns into new and healthy ones you can happily live with for a lifetime.

Don’t be tempted to measure success by the number of dress sizes dropped or belt notches tightened in just 3 months. It’s a real achievement to lose 5% of your initial weight in whatever time it takes. And the real success is preventing weight regain by sticking to your healthier lifestyle.

If you do want to lose a bit more weight, take the pressure off for 3 months before you restrict calories again. This will give your body time to adjust to its new engine size. And it will give you practice in learning to listen to your body’s natural signals for feeling hungry and feeling full just as babies and toddlers do. An alternating weight loss/weight maintenance pattern like this will help you become a successful full-time weight maintainer.

Of course, in theory preventing weight regain should be a lot easier than losing weight. But if anything, it is the most critical stage of all. Here’s why regaining weight after you have been on a diet is all too easy. For starters your body fights back. Food-seeking behaviour is wired into our brains to make sure we survive when our energy intake is low. So, despite your good intentions, those hormones fly into action to stimulate your appetite and encourage excessive food intake. But your body is a smaller engine at your new weight and it needs less fuel to run. And if you lost weight rapidly and without exercising, then chances are you also lost excessive amounts of muscle, making your engine size even smaller.

Another reason why it can be so hard to maintain weight loss is that your resting metabolic rate (RMR) has dropped so your energy expenditure declines by as much as 10%. This is how nature helps animals adapt to the environment in which they live. If food is scarce, the body reduces engine revs so it can get by with less fuel.

To lose weight and keep it off, the bottom line is that you need to remain focused on eating well and exercising regularly. The 10 golden rules of preventing weight regain are:

  1. Never skip meals (or you will slow your metabolic rate).
  2. Eat a good breakfast.
  3. Eat at least three times a day (but listen to your appetite and eat accordingly.
  4. Limit television to less than 12 hours per week.
  5. Choose low GI carbs at every meal.
  6. Eat lean protein sources at every meal.
  7. Don’t skimp on the fats – just choose healthy ones.
  8. Eat two serves of fruit and five serves of vegetables every day.
  9. Schedule (put it in your diary if you have to) moderate physical activity for 30–60 minutes on six days out of seven.
  10. On the seventh day, relax and enjoy.

The recommendations are sensible, as usual. But there seems to be an inherent contradiction in the recommendations for a pre-diabetic person to eat a lot of fruit. Fruit is great, but it also contains a lot of sugar.
As a "type 3" (glucose intolerant), I found that far more accurate than my fasting blood sugar was the frequency and amount of urine I passed at night. As soon as I cut out the heavy fruit intake, my nocturnal freqency and quantity dropped back to normal.
Secondly, I wish some of the experts would actually test their own blood sugar increase when eating, say, rye bread, vs white bread. One has an OK GI, the other is poison. But an hour after ingestion, both cause a big jump in blood sugar.

Fruit and vegetables. When we say seven serves we in fact mean at least five serves of vegetables (not including the starchy ones) and two or three of fruit. Thanks for pointing out the fact that our story may confuse readers. We have clarified this. Not sure what you are trying to say re the bread – obviously all carbs will cause a rise in BGL, but the low GI ones less so which is what we are aiming for. Many rye breads still have a relatively high GI, which is why it's important to encourage manufacturers to have their brands tested so that you can make an informed choice when shopping.

Tholzel: in the 10 rules is set CLEARLY "two" fruit portions and "five" vegetable portions. I'm also a prediabetic and I've found that I may eat 3 fruit portions a day with a terrific control not only in glucose leves but also in triglycerides. I'm a phisician that works a lot in teaching how to avoid diabetes , and measuring both, glucose and triglycerides, has taught to me a lot about food

I regularly measure capilar blood glucose & triglycerides, sometimes daily, and it's awesome what some meals could do to your body without our knowledge. For example, one night I ate french fries (small portion, 20 fries), meat lightly sauted in butter (quarter pound of meat), wine, vegetables pickled with vinegar, olives, and 2 cups of white dry wine (family dinner through Christmas), and a fistfull of raw hazelnuts and walnuts. My triglycerides rocketed from 313mg to 500+ in the next 12 hours! 6 days later I have 158mg. No potatoes, no buttered meat, but a lot of omega 3, flaxseed, whole grains in small quantities, 1 small apple every night, 2 other non starchy fruits in the day, lots of vegetables, soy protein, fish, a little roasted pork.
