Adipose Tissue is fat storing tissue in the body, made up of adipocytes, which makes up about 90% of the fat in the body mostly in the subcutaneous deposits.

Adipocytes are fat cells or lipocytes. These cells are specialized in the synthesis and storage of fat in the body. The primary role of adipocytes is to maintain proper energy balance in the body by storing calories in the form of fat (lipids) so as to be used when needed by the body.

The Effect of Ingested Macronutrients on Post-Meal (Postprandial) Ghrelin Response: A Critical Review
Ghrelin is a powerful orexigenic gut hormone with growth hormone releasing activity. It plays a pivotal role for long-term energy balance and short-term food intake. It is also recognized as a potent signal for meal initiation. Ghrelin levels rise sharply before feeding onset, and are strongly suppressed by food ingestion. Postprandial ghrelin response is totally macronutrient specific in normal weight subjects, but is rather independent of macronutrient composition in obese. In rodents and lean individuals, isoenergetic meals of different macronutrient content suppress ghrelin to a variable extent. Carbohydrate appears to be the most effective macronutrient for ghrelin suppression, because of its rapid absorption and insulin-secreting effect. Protein induces prolonged ghrelin suppression and is considered to be the most satiating macronutrient. Fat, on the other hand, exhibits rather weak and insufficient ghrelin-suppressing capacity. The principal mediators involved in meal-induced ghrelin regulation are glucose, insulin, gastrointestinal hormones released in the postabsorptive phase, vagal activity, gastric emptying rate, and postprandial alterations in intestinal osmolarity.
These charts give the relative amounts of saturated, monounsaturated, and polyunsaturated fatty acids found in common the common food oils.
The Mediterranean diet is associated with a lower incidence of atherosclerosis, cardiovascular disease, neurodegenerative diseases and certain types of cancer. The apparent health benefits have been partially ascribed to the dietary consumption of virgin olive oil by Mediterranean populations. Much research has focused on the biologically active phenolic compounds naturally present in virgin olive oils to aid in explaining reduced mortality and morbidity experienced by people consuming a traditional Mediterranean diet. Studies (human, animal, in vivo and in vitro) have demonstrated that olive oil phenolic compounds have positive effects on certain physiological parameters, such as plasma lipoproteins, oxidative damage, inflammatory markers, platelet and cellular function, antimicrobial activity and bone health. This paper summarizes current knowledge on the bioavailability and biological activities of olive oil phenolic compounds.

Most people are eating a poison every day without giving it a second thought. This substance can increase belly fat and consuming even small amounts (2% of total energy intake) is consistently linked to coronary heart disease. The research also says that this stuff can increase visceral fat, contribute to insulin resistance, increase risk of type 2 diabetes, increase bad cholesterol, decrease good cholesterol, trigger systemic inflammation and adversely affect almost every cell in your body.

A news media feeding frenzy erupted recently when a new diet study broke in the New England Journal of Medicine (NEJM). Almost all the reporters got it wrong, wrong WRONG! So did most of the gloating low carb forumites and bloggers. Come to think of it, almost everyone interpreted this study wrong. Some valuable insights came out of this study, but almost everyone missed them because they were too busy believing what the news said or defending their own cherished belief systems …
