What are signs your diet lacks enough healthy fats?

If you're not getting enough healthy fats, your body sends clear signals. Persistent hunger shortly after meals is common, since fats slow digestion and promote satiety. You might notice dry, flaky skin or a dull complexion, as essential fatty acids are critical for skin barrier function. Brain fog, difficulty concentrating, and mood swings can occur because the brain relies heavily on fat. Fat-soluble vitamins like A, D, E, and K won't absorb properly, potentially leading to deficiencies. You may also experience dry eyes, brittle hair, joint stiffness, and hormonal imbalances since fat is essential for hormone production. Feeling constantly cold or fatigued are additional signs your body may be running low on this essential macronutrient.
