The Power of Knowing Our Heart Health Numbers for Long-Term Wellness – With Visual Examples

We’ve previously discussed the importance of heart and metabolic health, especially how indicators like LDL cholesterol (“bad cholesterol”) are associated with long-term health and longevity.

But how long should we aim to keep these numbers in a healthy range?

Let’s explore this with an example.

 

Three Different LDL Journeys

Meet three individuals who all started with healthy LDL levels:

Mark S. maintains healthy LDL levels over 36 years.

Susan T. started with healthy levels, but they went up after year 23 and never really came back down.

Al K. started with healthy levels, but after year 10 they kept climbing and never really leveled off.

Note: These are fictional examples created for illustrative purposes. In real life, LDL levels may not be measured yearly and can vary due to many factors.

 

Based on the Examples Above…

1. Is there anyone who has sustained healthy levels of LDL over 36 years?

Yes: Mark S.

 

2. Is there anyone who maintained healthy levels of LDL for a while but saw them worsen over time?

Both Susan T. and Al K.

 

3. Assuming no other factors are contributing to health risk, how would you rank the chances of long-term heart and metabolic health and longevity among the three individuals?

Ranking from high to low: Mark S.à Susan T. à Al K.

So the next question is: Why is there a difference between Susan T. and Al K.? Aren’t they both at risk after their LDL levels are no longer “normal”? True—they are both at increased risk. However:

• Even Mark S. is not completely risk-free. That said, consistently healthy LDL levels may give him a better chance of maintaining heart health and longevity than those who with abnormal levels
• For people whose LDL levels become abnormal over time, the longer they maintain healthy LDL levels, the better the potential for long-term heart and metabolic health and longevity
• Susan T. may have a better chance than Al K., because she maintained healthy LDL levels for a longer period

 

4. What might Mark S. be doing to continuously maintain healthy levels of LDL?

• Possibly nothing specific—he may be genetically predisposed to have healthy LDL levels (lucky him!). His age could also be a factor.
• He may be checking his LDL levels regularly and taking steps to support healthy levels if they begin to rise
• He could be consistently following a healthy lifestyle—balanced diet, appropriate supplement use, regular exercise, and weight management
• He might be maintaining light heart-healthy habits most of the time and strengthening those habits when his LDL levels get close to the upper limit of what he considers ideal (based on guidance from his HCP)

 

5. What might Susan T. and Al K. be doing—or not doing—that resulted in shorter periods of healthy LDL levels?

• Possibly nothing wrong—they may be doing everything “right,” but still face challenges due to factors like age or genetics
• They might not be checking their LDL levels routinely, so they don’t know when to take actions
• They may have only adopted a few—or none—of the habits that support heart and metabolic health
• They might be younger and genetically predisposed to healthy LDL levels, but have long-standing poor lifestyle habits working against their heart and metabolic health

 

6. What if Susan and Al had never adopted any heart-healthy lifestyle habits—through their daily FUEL (Food, Use of supplements, Exercise, and other Lifestyle habits)? Is it ever too late for them to start? 

In general, the earlier they take actions, the better.

However, health benefits build up over a lifetime.

Even though we can’t go back in time, it’s never too late to start.

The example below shows how Al’s LDL levels could change depending on when he starts taking action—and whether he maintains those actions over time.

7. What could Mark S, Susan T. and Al K. do to support healthy LDL levels—and overall heart and metabolic health? 

Here are some important steps they (and anyone) can take:

a. Track and understand your key health metrics

• • For instance, adults over 20 with normal LDL levels and low risk of heart and vascular diseases are generally advised by the American Heart Association to have their cholesterol checked once every 4-6 years[1]
  • Those with higher risk may need more frequent testing
  • The goal is to build and maintain a good track record of heart and metabolic health over time

b. Talk to your HCP about your family history and ideal target ranges

• • Your health profile, family background, and age all influence what’s considered a healthy level for you

c. Review your current levels and trends with your HCP

• • Understanding how your numbers have changed over time can help identify early patterns or risks—and guide the appropriate actions to take

d. Whether your levels are currently normal or not, ask your HCP about ways to support long-term health

• • Lifestyle changes, routine monitoring, and other options may help you maintain—or return to—healthy levels

 

Note of Caution: 

The longer our LDL levels (or other heart/metabolic metrics) remain outside the healthy range, the more likely they may be associated with medical conditions.

That’s why it’s important to work with qualified HCPs when we notice signs of abnormal levels.

 

On the Positive Side:

The more years we maintain healthy heart and metabolic metrics, the better our chances of long-term health—and possibly, a longer, healthier life.

We hope this article helps illustrate the importance of maintaining healthy heart and metabolic metrics—and the practical steps anyone can take to support that journey.
