It works more slowly than the nervous system but has longer-lasting effects. Key glands include the pituitary, thyroid, adrenal glands, and pancreas. A healthy lifestyle—including good nutrition, sleep, and stress management—supports hormone balance and overall well-being. Hormonal regulation is whole-body effort, not limited t

Fats are vital for energy, hormone production, vitamin absorption, and cell structure. They protect organs, regulate body temperature, and enhance food flavor and satiety. Essential fatty acids like omega-3 and omega-6 must come from the diet, supporting critical functions. A balanced intake of healthy fats supports growth, development, and overall health, making fats crucial beyond just being a calorie source.

The body needs high-quality protein for muscle, hormone, and cell function. Not all proteins are equal—animal proteins like eggs and meat are more bioavailable and complete in essential amino acids than most plant proteins. Research shows most people, especially Americans, don’t get enough quality protein. A 135 lb person needs 75–100g daily, not just 50g. Plant-based claims from films like The Game Changers often ignore real nutritional science and amino acid bioavailability
