My only concern is I am currently losing weight in spite of a large dinner and desert after. Night before last was about 1/2 kilo of home made apple pie
. will I receive enough calories long term?
Speaking of my wife. She is a nurse in a cardiac ward. She told me recently, the one thing all the doctors she works with have in common, is they cycle.
Patt, that you don't get cravings til you start eating rings a bell personally and with my clinical experience. Let me try and flesh out the physiology.
I believe it starts with coming to the table dehydrated. Appetite is very much associated with hydration state. If you are not carrying enough fluid on board, then your body will pull fluid from tissue (muscles, mucus membranes, etc) to sustain blood volume. The lack of interstitial fluid compromises the ability of nutrient and oxygen flow to cells, and the removal of metabolic waste and CO2. You end up with a lower pH in working tissue, and compromised glucose delivery. So negative fluid balance can trigger excessive appetite.
Once you start loading food on board at a main meal, your body will want to shunt blood preferentially to the gut to facilitate digestion and absorption. Starting a meal in a dehydrated state will only compromise non digestive tissues more so. This includes many of the neural and endocrine receptor networks that are involved in appetite regulation.
The solution is to get a half liter of fluid into you before main meals, preferably 3-15 minutes prior. This especially applies to breakfast, because we are all dehydrated on awakening, and many of us get through to lunch having had only 1-2 cups of caffeine.
Negative fluid balance also makes the blood more viscous. When you start eating, it gets even more so as you increase fat, AAs, and glucose transport. There is a strong association between heart attacks and strokes within 2 hours of heavy meals, especially fattier meals!!! something for the LCHF (and low vegetable) brigade to contemplate. When you understand how vegetables (and unprocessed starches) slow absorption of everything including fat and protein, you can appreciate more so how they protect the vascular system.
OK, I am running out of time here.
To cut to the chase, to quell appetite that specifically triggers during or shortly after eating, try these:
- hydration as above.
- some stretching and calming of the mind and emotions before eating. coming out of a high stress incident and straight into a meal is more likely to see you overeat. stretching will help to relieve stress and circulate adrenalin which mobilizes fatty acids. Both will suppress appetite. Exercising before meals also suppresses appetite for similar reasons, though light to moderate is better. Intense bouts of exercise followed immediately by eating doesn't give the body time to shunt blood to the gut and prepare gut enzymes for processing the meal.
- we discussed here a week or so ago that eating raw food first prevents overfeeding (i.e. eat salad before pasta and vege). this flows into just eating slower, enjoying conversation or a relaxing environ. The slower we eat the less likely we are to be enslaved to false appetite signals.
- many people with dysregulated blood glucose do seem to do better on LCHF, so benefit from dramatically reducing starch, even unprocessed. However it is my view one can normalize glucose levels and inappropriate appetite on HC or LC diets, if you get all the stuff mentioned above right. Inappropriate appetite starts with excessive excitement and busy-ness in one's life. The Blue Zones all share in common a less rushed life and more relaxation around meals. If we do that then we shouldl be able to tolerate carbs without wanting to overeat.
Major flaws in LCHF ideology are that it blames the obesity and diabetes epidemic on high carb low fat diets.
However, consider this:
- 75% of the world's population is lactase deficient after weaning, therefore a significant source of dietary fat (dairy) is inappropriate for them.
- homosapiens have been eating grains for at least 100,000 years (not the 20,000 spruiked by LCers). In that time, grains have never been associated with obesity epidemics, until the last 40 years. It is very sloppy logic to blame a whole macronutrient category for a health issue that is 40 years old. there is a myriad of other cultural and dietary factors that have changed in the last 40 years.
- the leanest and most long lived people on the planet (Blue Zones and many African traditional tribes) eat high carb, and very little animal produce. Diabetes and obesity are rare in both groups.
