Key takeaways:
This week, we're diving into metabolic health and its crucial role in brain function. Learn about the strategic timing of protein intake for optimal brain health, understand what high triglycerides mean for your cognitive future, and explore why Alzheimer's is sometimes called "Type 3 Diabetes".

Protein Timing for Brain Health
Did you know that strategic protein intake can be a game-changer for your brain's performance and long-term health?
The Science: Protein provides essential amino acids that are fundamental building blocks for neurotransmitters. Consuming ~1g of protein per pound of body weight daily supports brain cell maintenance, neurotransmitter production, and helps stabilize blood sugar levels. It also helps maximize muscle growth and maintenance, which in turn is critical to dementia prevention.
The Simple Solution: Spread your daily protein intake across 3-4 meals, ensuring no single meal exceeds 40g. For a 150-pound individual, aim for about 150g of protein daily.
Quick Tips:
- Start with a protein-rich breakfast - this sets you up for the day
- Include a palm-sized portion of protein at each meal
- Choose high-quality sources like eggs, Greek yogurt, chicken, fish, and lean meats
- Use a protein shake as a convenient backup option if you're struggling to meet your goals
BetterBrain Tip: Many people notice improved appetite regulation and body composition within weeks of optimizing their protein intake. Plus, increased protein intake is great for reducing glucose spikes.

Triglycerides: Fat Storage with Brain Impact
What it is: Triglycerides are the most common type of fat in the body, essential for energy storage but potentially harmful when elevated. Recent studies have shown that high and variable triglyceride levels may increase cognitive decline and Alzheimer's risk, though the exact mechanism isn't fully understood.
Why it matters: Beyond their direct impact on brain health, triglycerides can indirectly affect cognition by contributing to metabolic syndromes like diabetes. Their levels also serve as an important marker of cardiovascular health, which is closely tied to cognitive function through blood vessel health and brain circulation.
How to improve it: Start with daily movement and focus on reducing refined carbs and sugars in your diet. Include regular servings of omega-3 rich foods like fish and nuts, and maintain a healthy weight through consistent habits rather than crash diets. If levels remain high despite lifestyle changes, your doctor may recommend medication to help protect your brain.

Metabolic Health: Your Brain's Hidden Protector
Bottom Line: Poor metabolic health can significantly increase dementia risk, even before diabetes develops - but simple lifestyle changes can help protect both body and brain.
Metabolic syndrome affects about 40% of adults over 60 in the U.S., though most don't realize it's affecting their brain health. Research following 175,000 people found that having just three metabolic risk factors (like high blood sugar or blood pressure) increases dementia risk by 12%.
The good news? Small changes can make a big difference. Taking a short walk after meals, drinking vinegar before eating, or simply changing the order you eat your food (vegetables first, carbs last) can help stabilize blood sugar and protect your brain.
BetterBrain Takeaway: Don't wait for diabetes to develop. Managing your metabolic health early through diet, exercise, and regular testing could be one of the most powerful ways to protect your brain health.
