The 31st of December will see the old year out and the new year in. On January 1st we all have gritty determination to follow our new year’s resolutions…. Have you ever sat down in December and reviewed your list – ticking them all off as “done!”
The transition of 31st of December to the 1st Jan is just another moment in time, so what gives us the added optimism that THIS moment will bear the rewards we have obviously sought but not found?
I was in the supermarket planning my New Year’s eve meal. Traditionally the day before a diet, it is tempting to have an all-out blow-out, stock piling all those favourite extravaganzas, as we don’t plan to see them again for a while.
But…have you ever wondered why we feel hungrier the morning after a big meal?
It is a CHAIN REACTION!
A complex combination of factors regulate our appetite. “Appetite receivers” in the brain consolidate and analyze neurological, hormonal, mechanical and psychological signals, and hence the unwelcome awakening of hunger consciousness.
Best explained by http://www.livestrong.com, they give this explanation:
Your appetite centers are located in the nuclei within your brain stem and hypothalamus. The cells in these areas respond to your blood glucose level, to nerve impulses arising from your gastrointestinal tract, to various hormones, including ghrelin, leptin and thyroid hormones, and to numerous other stimuli. Fluctuations in hormone and blood glucose levels impact your appetite in a predictable fashion. For example, a falling blood glucose level or an increasing ghrelin level stimulates hunger, while rising glucose or leptin levels suppress your appetite. Insulin influences the levels of many other appetite-regulating factors.
Insulin and Appetite
Insulin is a hormone produced by your pancreas in response to consuming a meal. Insulin stimulates the cells in your liver, fat tissue and muscles to absorb glucose and then to burn it for energy or store it for future use. As insulin drives your glucose level downward, your pancreas and adrenal glands produce counter-regulatory hormones, such as glucagon and epinephrine. The appetite centers in your brain are stimulated by falling glucose levels and counter-regulatory hormones, making you feel hungry again. Thus, the more insulin your pancreas produces in response to a given meal, the greater the subsequent rebound in your appetite.
When you eat a meal at bedtime, particularly one rich in sugars and other simple carbohydrates, you generate an insulin surge from your pancreas. Upon retiring, this insulin begins pushing glucose into your cells, a process that continues as you sleep. During the night, a continual drop in your blood glucose stimulates the release of counter-regulatory hormones, leading to stimulation of your appetite centers. Unless you get up in the middle of the night to satisfy your appetite, you will be hungry upon arising in the morning.
Considerations – The factors that regulate your appetite are not as straightforward as was once believed. The interactions among ghrelin, leptin, insulin, glucose, thyroid hormones, growth hormone and other determinants of hunger or satisfaction are intricate and only partially understood. To confuse matters further, sleep-inducing hormones, such as melatonin, exert their own influences on your appetite, and changes in sleep patterns can alter the way your brain responds to hunger signals. If you are trying to control your weight, the timing and composition of your meals could impact your success.
This is what I want to learn more about during my 2017 journey.
In the meantime, in the supermarket, I put back all the naughties on my NYE list, and decided I don’t need a moment in time to start the diet. I can make a delicious and light celebration, that everyone will enjoy, not feel deprived and I will wake up on Jan 1st ready to CONTINUE rather than start….
I will post my healthy NYE pictures and recipes during the first week of Jan!!
