Dear Mark: What Does High HDL Mean? and Is Exercise Good or Useless for Weight Loss?

At present’s version of Expensive Mark is a comparatively temporary two-parter, but it surely’s a great one. First, I reply a query about HDL. Is greater good? Is greater (typically) unhealthy? How does an individual make sense of all of the seemingly conflicting data? Then I clarify how two statements about train and weight reduction may be concurrently right and apparently contradictory. Is weight reduction efficient or ineffective for weight reduction, or what?

Let’s go:

I'm undecided I perceive the HDL one. So greater HDL might result in cardiovascular points, however greater HDL is a byproduct of a wholesome life-style? I feel I'm lacking one thing. Does anybody perceive this to clarify it?

Enable me to supply extra particulars.

Increased HDL is sophisticated, and earlier than we will interpret its well being implications we should perceive the various roles it performs in immune and cardiovascular well being.

HDL reduces and neutralizes oxidative, inflammatory brokers that injury LDL particles and result in atherosclerotic lesions in our arteries. They will even clear oxidized LDL particles themselves, shuttling them to the liver for processing.

HDL also can assault and destroy pathogens and their toxins. In some instances, HDL particles carry antimicrobial poisons and trick pathogens into consuming them. HDL additionally “grabs” bacterial endotoxins and neutralizes their toxicity.

Typically, excessive HDL signifies an ongoing inflammatory assault or an infection. As an example, excessive omega-6/omega-Three ratios have been proven to extend HDL ldl cholesterol, however they don't suppress atherosclerosis. How can this be?

Maybe the excessive omega-6/low omega-Three consumption is growing the susceptibility of LDL to oxidative injury. That’s what different research present, typically—consuming extra dietary omega-6 (linoleic acid) makes your lipoproteins extra polyunsaturated, unstable, and liable to oxidative injury. And since one in all HDL’s major jobs is to scrub up oxidized LDL and the brokers that oxidize it, the physique may ramp up HDL manufacturing as a response to elevated omega-6s.

Excessive HDL may be “unhealthy” if it signifies an an infection or excessive oxidative stress. Nevertheless it’s additionally “good” as a result of it means an individual’s physique is producing extra HDL to take care of the an infection or irritation.

Earlier makes an attempt to brute-force excessive HDL through medicine like torcetrapib have failed miserably. Really, they succeeded in boosting HDL to unimaginable heights, however they failed by killing the individuals who skilled the HDL boosts.

HDL testing might use some updating, I feel. The HDL measurement we get on the physician typically refers back to the weight of the HDL. In case your HDL has picked up toxins, it is going to weigh extra and are available up greater than an individual whose HDL has not—even if in case you have the identical variety of HDL particles. Much more illuminating is the HDL particle quantity. When HDL particle testing turns into extra routine, I feel we’ll have a greater thought of what’s occurring.

Thanks for the query!

I'm taking the Primal Well being Teaching Certification course and I simply began Key Idea #7 this morning, titled Train is ineffective for weight administration. Think about my shock once I learn #10 above: Train is necessary for weight reduction. Trying ahead to studying extra about this and getting some decision round this matter in order that I've a transparent message for my purchasers.

Nice query!

Word the slight nuance: train may be each ineffective for weight administration and necessary throughout weight reduction.

Train is a significant component in Primal Well being Teaching in any case. If it weren’t necessary, we wouldn’t point out it. It’s simply not sufficient for weight reduction.

What we had been making an attempt to emphasise is that purchasers not rely on train for weight reduction. Doing so results in many detrimental outcomes:

1. Promotes an “earn it, burn it” mindset, the place unhealthy meals decisions may be “paid off” by cranking out one other hour or two on the treadmill or on the bike. This solely encourages folks to make these unhealthy meals decisions.
2. Introduces guilt. If train is the key determinant of weight reduction and also you’re not reducing weight, it essentially follows that you simply’re a lazy, good-for-nothing layabout who simply must work tougher. A small subset of individuals reply to this sort of motivation positively. Most will retreat into junk meals and withdraw fully.
3. Results in burn-out, particularly in girls. You don’t need to get into the train rat race, the place train turns into a depressing job you clock into day in and time out. Train must be joyous, intense, and, sure, difficult. It shouldn’t be drudgery. It shouldn’t be mind-numbing. It must be acutely aggravating however not chronically so.
4. Doesn’t actually work all that nicely. Train can actually improve weight reduction alongside eating regimen and make weight achieve tougher, however as a standalone intervention it falls quick. There are thousands and thousands of examples of people that attempt to train their strategy to weight reduction (look ahead to a bunch coming this January!) and fail miserably.

That’s totally different from utilizing train to boost and enhance weight reduction, nonetheless. Alongside a great eating regimen, train can:

• Show you how to preferentially lose fats and retain/achieve muscle. Food regimen helps you shed weight. Train impacts what sort of weight you lose.
• Create a glycogen debt and improve non insulin-dependent glycogen storage, so you possibly can eat (post-workout) carbs with out altering insulin ranges by a lot and shutting off fats loss.

These are the 2 most necessary roles train performs in fats loss, however there’s additionally extra. If you wish to understand how precisely train can improve fats loss, try the publish I wrote earlier this yr. It comprises plenty of data you should utilize to enhance your shopper outcomes.

Thanks in your query, by the best way! It’s an necessary distinction that must be made.

That’s it for this week, everybody. I hope you all had a unbelievable vacation. Thanks for studying!
