Vigorous exercise causes muscles to produce lactate - which crosses the blood-brain barrier and is a messenger for the brain to produce neurotrophic factors like BDNF.

BDNF is like a youth elixir for the brain and the signal that activates it is lactate from high-intensity exercise.

If you want to bathe your brain in BDNF - vigorous-intensity exercise is one of the best ways to do it.

No pharmeceutical can rival exercise when it comes to slowing the aging process - particularly the aging brain.

A large-scale trial investiated th effect of aerobic exercise (running, cycling) on cognition in the 20- to 67-year age range. Here’s what they found:

Better thinking skills as you age: Exercise helped people’s executive function - that’s your brain’s ability to manage tasks, plan, and focus.

Thicker brain cortex, regardless of age:
• Higher cognitive reserve- aiding task flexability and improvisation
• Resilience against brain aging and neurodegenerative disease
• Improved neural plasticity, essential for lifelong learning and skill acquisition
• Bolsters emotional regulation

Real-world Application: The way the workouts were implemented could be a practical recommendation for improving brain health for the general public.

Consistency is key: participants exercised about 40 minutes, four times a week for six months.

Gradually increasing effort: they started easy (55-65% max heart rate) and slowly increased their workout intensity (65%-75% max heart rate).

Monitoring progress: using heart rate monitors helped them stay in the desired exercise intensity.

Flexibility: participants could choose the exercise (running or cycling) they preferred and set their schedules.

I think everyone is starting to get the #Satiety concept. 😁

But some people still don’t quite get the idea of a satiety score based on satiety *PER CALORIE*. 😬

Hopefully this graphic helps! 🙌🏼

Could you eat all this in one day?

750 grams of protein foods: chicken breast, beef steak, salmon, chicken liver, mackerel, and shrimp.

Add some parmesan cheese (28 grams), greek low-fat yogurt (150 grams) and cottage cheese (92 grams), and also some egg whites (100 grams).

Also, add 820 grams of vegetables: Brussels sprouts, broccoli, chard, spinach, kale, asparagus, bok choy, and lettuce.

All the foods above combined make up 2,000 calories. Could you even eat it in one day? @martykendall2 asked people to try this, and they struggled to do it.

Alternatively, you could eat one large bag of potato chips in one day – and nothing else. It may have the same 2,000 calories, and you could be starving at the end of the day.

The difference is the #satiety per calorie effects of the foods.

In our @JoinHava satiety scoring, the mixed protein foods and vegetables day got an average score of 77 (very high).

The potato chips get a satiety score of 2.

Same calories. An entirely different effect. A calorie is not a calorie.

This is an extreme example of the concept, but there are many smaller or even tiny tweaks you could do over the day, and they all add up. They add up to health, energy, fitness, and strength... or the opposite.

Better reasons for exercising @developEmental @sonofachampion1

[Dr. Rhonda Patrick @foundmyfitness]

Exercise is *remarkably* beneficial for the brain.

High fitness levels in midlife delayed dementia onset by 9.5 years in women. Larger brain volumes have also been linked to increased physical activity.

Maintain youthful brain volume by embracing exercise. We can transform our brain health as we age.
