For decades, heart health has been simplified into two core messages: eat well and exercise regularly. While these are undeniably important, they represent only a small part of a much larger, more complex picture.
At Levitas Academy, we take a deeper, more scientific approach—exploring the true factors affecting heart health, including metabolic, inflammatory, hormonal, and lifestyle influences.
Below are the most frequently asked questions that challenge conventional thinking and expand our understanding of cardiovascular health.

FAQs – Understanding Modern Heart Health
1. What are the main factors affecting heart health?
Heart health is influenced by far more than diet and exercise alone.
Key factors include:
- Insulin resistance and metabolic dysfunction
- Chronic inflammation
- Hormonal balance (e.g., cortisol, testosterone, thyroid)
- Sleep quality and circadian rhythm
- Stress and nervous system regulation
- Nutrient deficiencies (e.g., magnesium, vitamin D)
- Gut health and microbiome balance
These interconnected systems determine how the cardiovascular system functions at a cellular level.
2. How does insulin resistance affect heart health?
Insulin resistance and heart health are closely linked.
When the body becomes resistant to insulin:
- Blood sugar levels rise
- Fat storage increases (especially visceral fat)
- Blood vessels become inflamed
- Lipid profiles become disrupted
Over time, this contributes to:
- Atherosclerosis
- Hypertension
- Increased cardiovascular risk
Insulin resistance is one of the most overlooked drivers of heart disease in modern medicine.
3. What is the role of inflammation in heart disease?
The connection between inflammation and heart disease is now well established.
Chronic, low-grade inflammation:
- Damages blood vessel walls
- Promotes plaque formation
- Destabilises existing plaques
This increases the risk of:
- Heart attacks
- Stroke
- Vascular disease
Rather than cholesterol alone, inflammation is increasingly recognised as a key underlying mechanism.
4. Are lifestyle factors more important than genetics for heart health?
While genetics play a role, lifestyle factors affecting heart health often have a greater impact.
These include:
- Diet quality
- Physical activity
- Sleep patterns
- Stress levels
- Environmental exposures
Importantly, lifestyle can modify gene expression (epigenetics), meaning your daily choices can influence your long-term cardiovascular outcomes.
5. How does stress impact heart health?
Chronic stress activates the sympathetic nervous system, leading to:
- Elevated cortisol levels
- Increased blood pressure
- Higher inflammation
- Disrupted sleep
Over time, this creates a physiological environment that promotes cardiovascular disease.
Stress is often an invisible but powerful contributor to heart dysfunction.
6. Can poor sleep affect cardiovascular health?
Yes—sleep is a critical yet underestimated factor.
Poor sleep:
- Increases insulin resistance
- Raises inflammatory markers
- Disrupts hormonal balance
Even a few nights of inadequate sleep can negatively affect cardiovascular function.
7. Is cholesterol the main cause of heart disease?
Cholesterol plays a role, but it is not the full story.
Modern understanding suggests that heart disease is driven by a combination of:
- Inflammation
- Oxidative stress
- Insulin resistance
- Endothelial dysfunction
Focusing solely on cholesterol overlooks these deeper mechanisms.
8. How does gut health influence heart health?
The gut and heart are closely connected through the gut-heart axis.
An unhealthy gut can:
- Increase systemic inflammation
- Affect lipid metabolism
- Produce harmful metabolites
Optimising gut health can therefore support cardiovascular resilience.
9. Can heart disease be prevented through lifestyle changes?
In many cases, yes.
Addressing key lifestyle factors affecting heart health can:
- Reduce inflammation
- Improve insulin sensitivity
- Support vascular function
Prevention is not just about avoiding disease—it’s about optimising the internal environment of the body.
10. What is the Levitas approach to heart health?
- Root cause analysis
- Metabolic and hormonal optimisation
- Inflammation reduction
- Personalised lifestyle strategies
The Bigger Picture
Heart health is not a single pathway—it is a network.
Diet and exercise are important, but without addressing:
- Insulin resistance
- Inflammation
- Stress
- Sleep
- Hormonal balance
…we only address part of the problem.
