Back in 2010 when I started writing this blog, it was all about gaining and losing weight. Since then the focus has broadened out to general good health, exercising and keeping one’s brain functioning. Nonetheless, I thought this study on fat and weight gain worth reporting.
Scientists from the University of Aberdeen and the Chinese Academy of Sciences have undertaken the largest study of its kind looking at what components of diet – fat, carbohydrates or protein – caused mice to gain weight.
Since food consists of fat, protein and carbs, it has proven difficult to pinpoint exactly what aspect of the typical diet leads to weight gain.
The mice were fed these diets for three months, which is equivalent to nine years in humans. In total over 100,000 measurements were made of body weight changes and their body fat was measured using a micro MRI machine. NeuroscienceNews.com image is in the public domain.

“Bone marrow adipose tissue has traditionally had a bad reputation because of its relationship to decreased bone mass but we now know that adipose tissue within marrow goes beyond the bone and also serves as an endocrine organ that can influence metabolism,” says co-lead author William Cawthorn, Ph.D., a U-M postdoctoral fellow in the MacDougald lab.

It has been known for its flavorful addition to soups and as a delicacy for dogs but bone marrow fat may also have untapped health benefits, new research finds.
A University of Michigan-led study shows that the fat tissue in bone marrow is a significant source of the hormone adiponectin, which helps maintain insulin sensitivity, break down fat, and has been linked to decreased risk of cardiovascular disease, diabetes, and obesity-associated cancers. The findings appear in today’s online-ahead-of-print issue of Cell Metabolism.
Bone marrow adipose tissue has primarily been associated with negative health effects, most notably because of a documented relationship to reduced bone mass and increased risks of fractures and osteoporosis. The new study however – which included people with anorexia, patients undergoing chemotherapy, rabbits and mice – suggests that this type of fat may also have benefits.
“These findings are significant because we’ve found that bone marrow adipose…

A little knowledge is dangerous. Cutting out fats from our diets because they are ‘bad’ is a perfect example of that.
Not all fats are bad, according to the American Heart Association.
Proper dietary guidelines say that fully 30% of our daily food calories intake should be in the form of fats. Also, 30% should be protein and 40% carbohydrates. So, fat is equally as important to us as protein.
Granted there are good fats and bad fats. The good fats serve important functions in our bodies. Life Clinic says, “Fat is the body’s major energy storage system. When the energy from the food you eat and drink can’t be used by your body, the body may turn it into fat for later use. Your body uses fat from foods for energy, to cushion organs and bones, and to make hormones and regulate blood pressure. Some fat is also necessary to maintain healthy skin, hair and nails, so you shouldn’t cut all fat out of your diet.”
