A chronic metabolic condition in which excess fat tissue disrupts hormonal, inflammatory and energy regulation. Weight alone is not enough: visceral fat, waist size, insulin resistance, blood pressure, sleep and comorbidities matter.

A monounsaturated fatty acid characteristic of olive oil, avocado, almonds and many animal fats. It is not a medicine, but it can make a low-carb diet gentler for the lipid profile and more stable for cooking, especially when it replaces excess refined seed oils.

One meal a day is an eating pattern where all food is compressed into a single meal; it may simplify energy control but requires attention to protein, nutrients, stress, and eating behavior.

A family of fatty acids that includes ALA, EPA and DHA. Nutrition should distinguish plant and marine forms: flax and chia provide ALA, while fatty fish, seafood and microalgae provide EPA/DHA, which are directly linked with membranes, inflammatory mediators and triglycerides.

A family of fatty acids that includes linoleic, gamma-linolenic and arachidonic acids. Omega-6 fats are necessary, but modern diets often provide excess from sunflower, soybean and corn oils, deep-fried foods and industrial sauces while EPA/DHA intake is low.

An amino acid involved in the urea cycle, the liver system that detoxifies ammonia. Ornithine is connected with arginine, citrulline, protein metabolism and nitrogen handling, but supplementation makes sense only in specific contexts.

Female gonads containing follicles, supporting ovulation, and producing estrogens, progesterone, and other signals that shape the cycle, fertility, and metabolism.

The female reproductive cell that matures within a follicle, ovulates, and carries half of the future embryo’s genetic material; quality is closely tied to age and the maturation environment.

A state in which production of reactive oxygen species exceeds antioxidant and repair capacity. It is not always harmful: small oxidative signals are needed for adaptation, but chronic excess can damage cells and tissues.

A hormone and neuropeptide involved in labor, lactation, attachment, social regulation, stress and pain sensitivity. It should not be reduced to a “love hormone”; its effects depend on context, receptors, safety and nervous-system state.
