The misconception that all fats are bad is a serious error in judgment that can have adverse effects on the body. Healthy unsaturated fats found in avocados and nuts are required because they contain unsaturated fatty acids, which are important for brain function and the formation of neurotransmitters. If omega-3 is in balance, inflammation can be controlled. I personally eat walnuts daily to maintain better mental clarity.

The absorption of vitamins occurs only when dietary fats are present. The fat-soluble vitamins (A, D, E, and K) are fat-soluble, and when there is no oil, the body can not utilize these substances. Adding olive oil to salads can help you obtain the benefits of the nutrients you eat. Improved skin health can result from the proper utilization of vitamin E, which requires the absorption of fat.

Replacement strategy works better than elimination. Exchange processed fats for avocado instead of mayonnaise. Use nut butters instead of cream cheese. I cook with coconut oil instead of butter. Your meals become healthier while maintaining flavor.

Observe metabolic improvements within a few weeks. A balanced intake of fat helps stabilize blood sugar levels. Your energy levels should remain consistent throughout the day. After increasing healthy fat intake, my cravings decreased markedly. Your body works best with the right balance of fat.
