Dear Mark: Sugar Cravings

sugarDear Mark,

I do pretty well in the fitness department, love my veggies and get plenty of protein. My problem is that I can’t seem to shake my sugar cravings. Suggestions?

I get some version of this question on a fairly regular basis. A common theory says that we evolved to crave sweet tastes in order to seek out healthy fruits to diversify our diets. The problem comes in the current age when our inclination is bombarded with the likes of Coco Puffs, Snickers and pudding packs.

Anaerobic Exercise HGH Link

BJSM 468x60I love this stuff. A recent study published in the British Journal of Sports Medicine may help explain what I have been saying for quite some time here: that exercise stimulates the natural production of growth hormone (the very same HGH we just wrote about yesterday). But it’s the type of exercise that makes all the difference. And this further confirms something else we’ve been saying: that it’s short intense bursts that work the best.

Study Finds Exercise Prolongs Lifespan

runA study published Tuesday in the online edition of the American Heart Association’s journal Circulation suggests that frequent exercise can reduce the risk of death in men.

To examine the link between fitness and mortality, Veterans Affairs (VA) researchers gathered fitness data on 15,660 male VA patients undergoing treadmill testing for various medical reasons. The men, who had an average age of 60, where then assigned to one of four groups based on their level of fitness.

According to the results, mortality risk directly correlated with fitness level, with men in the highest fitness category being the least likely to die when compared to their less fit counterparts. For example, across the eight year study period, 44% of the men in the least fit group died, compared to 30% in the moderately fit group, 15% in the highly fit group, and 8% in the very highly fit group.

The Hype Over Human Growth Hormone

HGHA lot of questions hit the MDA doorstep about HGH, Human Growth Hormone, and with good reason. It’s been touted in some circles as a bottled fountain of youth among other grandiose claims. Countless companies have jumped on that bandwagon, peddling worthless products with HGH labels.

We love to take on the propagandists and snake oil sales industries, and today will be no exception. Shall we begin?

The Basics of HGH
The natural HGH coursing through your body right now is, indeed, a perfectly remarkable anabolic hormone. It’s produced by the pituitary gland throughout life, but the levels gradually decline with age. The hormone is key for children’s growth and the health of the body’s organs. It stimulates the growth of muscle, bone and cartilage and enhances immune function. HGH is prescribed for children who are abnormally short in stature and for adults with diagnosed pituitary deficiency.
