Natural fatty acids may be saturated or unsaturated, and as the following data indicate, the saturated acids have higher melting points than unsaturated acids of corresponding size. The double bonds in the unsaturated compounds listed on the right are all cis (or Z).
My best diet is Basically organic veggies, veggie juice and organic meats. No processed food at all. No fruit juice, no artificial sweetners. No sugar, caffene, wheat, processed grains (whole grains are fine). Only occassional fresh fruit, don't let it become a sugar substitute.
Fad diets are considered those that tend to become popular for a given period of time, such as several years or even decades, and then become replaced by yet another dietary theory, which might even be very different (or completely opposite) compared to the preceding diet. Fad diets typically fall into one of two categories: low-carb/high-protein or high-carb/low-fat diets.
