Weight Loss Science

Lipids

Lipids (fats and oils) have almost twice the energy of either carbohydrates or proteins, because they’re made up from fatty acids, which are long chains of concentrated energy in carbon atoms. The intake of fatty acids is now recognised as one of the most important factors influencing health.

Unhealthy fats (Saturated fats)

Saturated fatty acids are found most commonly in animal and dairy products. When eaten in excess they increase blood cholesterol levels.

Healthy fats (Unsaturated fats)

Mono-unsaturated fatty acids are found mainly in plants, particularly in olive and canola oil. The main mono-unsaturated fatty acid, oleic acid, is the major oil in the Mediterranean diet and not surprisingly is found in olive oil. Because oleic acid lowers blood cholesterol levels, people who follow a traditional Mediterranean diet have low rates of heart disease.

Substituting monounsaturated fatty acids for saturated fats can help reduce the risk of heart disease.

Almonds are a source of healthy fat.
