Carbohydrates are the primary fuel of the human body. A few days without consuming carbs drives the body into a metabolic state known as ketosis‚ where the primary energy source is fat. A diet that induces a permanent state of ketosis is known as a ketogenic diet. This dietary regimen is currently gaining popularity‚ largely as a result of the publicity created by American physician Dr. Atkins for his Atkins diet. But while a ketogenic diet is commonly employed to successfully treat some ailments--notably

strong to support the animal’s weight. Typically‚ the weight-bearing muscles have a higher amount of connective tissue because they contain strong protein. The toughness of meat is contributed by the number of cross-linked chains per volume of meat explains a large amount of tenderness variation‚ produced by muscle type‚ animal age‚ type‚ and sex in different species. But connective tissue in meat is not desirable as it is tough and doesn’t usually result in a positive eating experience. During heating

The normal pulp is pink‚ coherent soft tissue is noted‚ dependent on its normal hard dentin for protection. Dentin and pulp are embryologically‚ histologically‚ and functionally the same tissue and therefore are considered as a complex.
