It has two main roles within the body; it is both an exocrine and endocrine organ. The exocrine role of the pancreas is part of the digestive system. When we eat a meal the pancreas will release digestive enzymes into the first part of the small bowel (the duodenum) to meet the food as it is transiting down the gastrointestinal tract. The enzymes include: Amylase – to break down carbohydrates Lipase – to break down ..read more

Ketogenic Diet Ketogenic diet is a low carbohydrate diet mostly being used for weight loss. There is not one “standard” ketogenic diet with a specific ratio of macronutrients (carbohydrates, protein, fat). But it typically contains less than 50 gr of carbohydrate , high amount of protein and moderate amount of fat.

How the Brain Controls Weight The brain plays a central role in the regulation of weight.

The ‘hunger system’ is comprised of the brain, nerves, gastrointestinal tract, fat, liver and muscle cells as well as numerous hormones.

Adipose and the Heart Let’s get technical and explore the relationship between adipose tissue (fat cells) and the heart. The outermost layer of the heart is called the epicardium and contains nerves, blood vessels, mesothelial cells, fat cells and connective tissue. The epicardial fat is derived from the same embryological tissue as visceral (intraabdominal) fat. Increased visceral and epicardial fat both lead to an increased risk of cardiovascular disease.   We can measure visceral fat by measuring your abdominal circumference. If the abdominal circumference is increased, then we c ..read more
