Just a personal reflection.
I was reviewing my food diary/cholesterol log. On those days when I had a tiny breakfast, and in effect, fasted throughout the day ( with some cups of tea and a bit of fruit), on those days, I noticed the cholesterol went back up!
superficially the report
Intermountain Medical Center. “Fasting reduces cholesterol levels in prediabetic people over extended period of time, new research finds.” ScienceDaily. ScienceDaily, 14 June 2014.
States that fasting reduces cholesterol over the longer term however “During actual fasting days, cholesterol went up slightly in this study, as it did in our prior study of healthy people, but we did notice that over a six-week period cholesterol levels decreased by about 12 percent in addition to the weight loss,” said Dr. Horne
“Because we expect that the cholesterol was used for energy during the fasting episodes and likely came from fat cells, this leads us to believe fasting may be an effective diabetes intervention.”
The process of extracting LDL cholesterol from the fat cells for energy should help negate insulin resistance. In insulin resistance, the pancreas produces more and more insulin until it can no longer produce sufficient insulin for the body’s demands, then blood sugar rises.
“The fat cells themselves are a major contributor to insulin resistance, which can lead to diabetes,” he said. “Because fasting may help to eliminate and break down fat cells, insulin resistance may be frustrated by fasting.”
Dr. Horne says that more in-depth study is needed, but the findings lay the groundwork for that future study.
“Although fasting may protect against diabetes,” said Dr. Horne. “It’s important to keep in mind that these results were not instantaneous in the studies that we performed. It takes time. How long and how often people should fast for health benefits are additional questions we’re just beginning to examine.”
This clearly leads into a re-evaluation of intermittent fasting
The European Society of Endocrinology asked “Could intermittent fasting diets increase diabetes risk? Fasting every other day to lose weight impairs the action of sugar-regulating hormone, insulin, which may increase diabetes risk.” ScienceDaily. 20 May 2018.
Their conclusion was “Fasting every other day to lose weight impairs the action of sugar-regulating hormone, insulin, which may increase diabetes risk, according to data presented in Barcelona at the European Society of Endocrinology annual meeting, ECE 2018. These findings suggest that fasting-based diets may be associated with long-term health risks and careful consideration should be made before starting such weight loss programmes”
Anecdotally this makes me think about lots of thin/skinny people I know, who have poor health!
