Weight Loss And Appetite Suppressants

For decades, the Holy Grail of the diet industry has been an all natural appetite suppressant with no side effects other than the intended weight loss. Like the Holy Grail, it has been elusive. The diet pharmaceutical companies thought they found it in starch-blockers, in ephedra, in fat binders. the list goes on. While many of these worked, they often came with a heavy list of side effects, many of them dangerous. After an initial flurry of excitement and sales, most were knocked off track by reports of dangers associated with their use, and some were even banned from U.S. sale.

The latest arrival on the Holy Weight Loss Grail circuit is an unprepossessing African succulent known as hoodia gordoni. Cleared for sale in the U.S. in early 2004, it has been steadily making a name for itself as a powerful appetite suppressant that can help you lose weight. Its popularity was significantly boosted by reports on 60 Minutes, ABC News and BBC News.

As part of the BBC report, BBC Two's correspondent Tom Mangold, actually traveled to Africa to sample the hoodia in situ. He and his cameraman, who also tested the plant, both reported feeling pleasantly full for nearly 48 hours after eating a piece of hoodia gordoni.

The hoodia plant has been used by the San tribesmen of the Kalahari desert for centuries to suppress the pangs of hunger on long hunts and trips. Modern research has isolated an 'active ingredient' known as P57. Though the research is still scanty, it appears to work by fooling the hypothalamus into thinking that there is more sugar in the blood than there actually is.

Does it actually work? It's really still too early to tell, but in one clinical trial conducted by Phytopharm, the company that holds the patent on the process to extract P57 from hoodia, human subjects taking hoodia reduced their caloric intake by as much as 1000 calories a day. The figures are impressive.

But is it safe? There again, the research is far to scant to make a reasonable decision on it. There are no known side effects - but it also hasn't been used outside one small tribe in Africa until the past two years. It's possible that there are side effects to long-term use that aren't yet evident.

Until then, use caution in purchasing products made with hoodia. Many of the commercially available products contain virtually no hoodia gordoni at all. Consult your doctor before undertaking any weight loss program that involves appetite suppressants. This is particularly important for those who've been diagnosed with diabetes or pre-diabetes, as the action of the hoodia plant can trick the body into thinking that the blood sugar is fine even as they approach hypoglycemic shock.

Strategic Weight Loss

One of the first things that you'll do when you decide to lose weight is to set a goal weight. For most, that goal will be their 'ideal weight', but for many, that 'ideal weight' may be exactly the wrong weight for them to be aiming for.

Years of dieting or being overweight have the physiological effect of moving the body's concept of the 'ideal weight' from what is truly considered ideal. The 'set point' is the weight at which your body naturally feels most comfortable.

If you've been overweight for a very long time, or if you've consistently 'yo-yoed', your body may respond to your initial weight loss by lowering its metabolism because it believes that you are starving to death. This slowing leads to discouraging plateaus that often knock people off their diets entirely, and lead to regaining all or part of the lost weight.

Instead of aiming for an 'ideal weight' that calls for you to lose weight steadily for months or even years, many experts recommend aiming for shorter-term attainable goals. Since the bulk of diet research shows that most dieters lose weight steadily for about 12 weeks, then hit a plateau, that's the number that they suggest you aim for. The strategy that many have found works best for them is one of alternating periods of weight loss and maintenance, each lasting 8-12 weeks.

Choose a realistic amount of weight that you can lose in 8-12 weeks. Figuring that the most reasonable and healthiest weight loss rate is 1-2 pounds per week, 30 pounds in three months is not unreasonable. Diet until you reach that goal, or for 12 weeks, whichever comes first, and then switch to a maintenance diet.

Why switch to a maintenance diet at that point? In part, you're giving yourself a 'breather', a break from more restrictive eating. The other part, though, is that you're re-educating your body and letting it establish a new 'set point'. Once you've maintained your new weight for 8-12 weeks, set another weight loss goal, and move back into weight loss mode. By giving your body a break from 'starvation', you'll have overcome its resistance to losing more weight, and be back to dieting for 'the first two weeks' - the weeks that most people lose weight more rapidly.

You'll also be giving yourself a chance to 'practice' maintaining your new, healthier weight. Researchers have found that more than half of the dieters who take off significant amounts of weight do not maintain that weight loss once they go 'off' their diet. By practicing weight maintenance in stages, you'll be proving to yourself that you CAN do it, and removing a powerful negative psychological block.

This will work with any long-term weight loss diet, no matter the focus. You'll find it much easier to do if you choose a diet that has concrete 'phases', like the South Beach or the Atkins, since the weight loss and maintenance phases are clearly laid out for you to follow. Regardless of the diet you choose, though, by alternating between weight loss phases and maintenance phases, you'll teach yourself and your body how to maintain a healthy weight.

A Simple Plan for Weight Loss

The math is pretty simple. One pound of fat equals 3500 calories. Want to lose a pound a week? Then you need to consume 3500 calories less per week than you use. That's about 500 calories a day. By cutting out 500 calories a day from your normal daily diet, while keeping your activity level the same, you can lose approximately one pound a week.

All right - that doesn't sound like much, especially if you're more than 25 pounds overweight. Study after study has shown, though, that those people who lose weight gradually - at a rate of 1-2 pounds per week -are far more likely to keep the weight off and maintain a normal weight for a lifetime.

So how much exactly IS 500 calories? If you're going to reduce your daily intake by 500 calories, it helps to know what you need to cut out, right? Here's how easy it is to lose 500 calories a day:

* Use milk instead of cream in your coffee. Savings? 50 calories per cup.

* Skip the butter on your baked potato. Savings? 100 calories

* Drink fruit-flavored water instead of a 16 ounce soda. Savings? 200 calories

* Skip the Big Mac and have a salad instead. A Big Mac weighs in at a whopping 460 calories. A fresh salad with a light dressing? Less than 100! Savings? 360 calories

* Pass by the bag of potato chips. An average snack size bag of chips has over 300 calories. Savings? 300 calories

* Eat your corn on the ear. A 1 cup serving of canned corn has 165 calories. An ear of corn has 85. Savings? 80 calories.

* Switch to low-fat cream cheese on your bagel. Savings? 90 calories per ounce.

* Love those fries and can't give them up? Swap the skinny fries out for thick steak-cut ones. Thin French fries absorb more oil than the thicker, meatier ones. Savings? 50 calories per 4 ounce serving

If you'd rather look at losing weight from an exercise perspective, you can also lose one pound a week by upping your activity level by 500 calories a day. How easy is that to do? Take a look:

* Take a half-hour walk around the park. Aim for a pace that's a little faster than a stroll, but not fast enough to be breathless. Burn: 160 calories.

* Get out your bike and take a ride. Tackle a few moderate hills and aim for about five miles total. Burn: 250 calories

* Go dancing - and really DANCE. The longer you're out on the floor instead of at the table drinking up high-calorie drinks, the more you'll get out of it. Dancing that makes you breathless and warms up your body will net you a nice calorie savings. Burn: 400 calories for one hour

* Swimming is great for you, and a lot of fun, too. The water resistance means you burn more calories, and you avoid the stress impact on joints from aerobics, dancing or walking. Do a few laps at a slow crawl - if you can get up to an hour you'll be doing great! Burn: 510 calories

* Get out into your garden. An hour of gardening tasks that includes bending and stretching can burn up to as many calories as a brisk walk. Burn: 250 calories.

* Play a game of tennis. Hook up with a friend for a weekly tennis game and you'll be amazed at the difference. One hour of vigorous tennis is one of the best calorie burners around. Burn: 800 calories

It’s important to keep in mind that all exercise/calorie numbers are based on a woman weighing 130 pounds. If you weigh more, you'll burn more. Want an added bonus to burning calories through exercise? When you exercise, you build muscle by converting it from fat. Three guesses which kind of body tissue burns more calories - even when you're not exercising. You got it - your body uses more energy to maintain and feed muscle than it does fat.

For best results, mix and match food savings with exercises that burn calories. Do keep in mind that eating less than 1000 calories a day for more than a few days will convince your body that it's starving and slow your metabolism. Keep calorie ranges reasonable, and consult a doctor if you want a quicker, more drastic weight loss.
