Eating low carbohydrate what threat that poses?
Do my friends think I’m suffering from halitosis?
I’ve got these sticks for measuring ketoacidosis
I’m taking supplements but I don’t know what the dose is
I’m trying hard to keep in a state of ketosis
I’m not sure what the right amount of weight to lose is
I’m sure I’ve put on a pound just through osmosis
Is eating this way risking osteoporosis?
Are my kidneys wrestling with metabolic acidosis?
My store of liver glycogen I don’t know how low is
Who knows what the glycemic load of oats is?
Does anyone know if I can eat samosas?
I do. The answer's "No!" :-D
I've had a humourless #LCHF "JERF" criticise me on Twitter for conflating Ketosis with Ketoacidosis. The eejit either didn't notice that I didn't write the poem, or did notice and was being intellectually dishonest. I suspect the latter. See Everybody knows.........Part 2. I know the difference.
The Green flags...
1. For a person with Insulin Resistance, an ad-libitum low-carb diet results in more weight loss than an ad-libitum high-carb diet.
See How low-carbohydrate diets result in more weight loss than high-carbohydrate diets for people with Insulin Resistance or Type 2 Diabetes , for an explanation.
2. For a person with Type 1 Diabetes Mellitus (T1DM), a lowish-slowish-carb (~150g/day) diet results in minimal disturbances to blood glucose levels and minimal bolus insulin doses.
See Diabetes: which are the safest carbohydrates? , to see which foods should comprise the ~150g/day.
3. For a person with LADA or MODY, see 2.
4. For a person with Type 2 Diabetes Mellitus (T2DM), a LCLF 600kcal/day Protein Sparing Modified Fast can normalise BG in 1 week and reverse T2DM in 8 weeks (provided there are sufficient surviving pancreatic beta-cells). See http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3168743/
"After 1 week of restricted energy intake, fasting plasma glucose normalised in the diabetic group (from 9.2 ± 0.4 to 5.9 ± 0.4 mmol/l; p = 0.003)." and
"Maximal insulin response became supranormal at 8 weeks (1.37 ± 0.27 vs controls 1.15 ± 0.18 nmol min−1 m−2)."

After 8 weeks, transition to a diet based on whole, minimally-refined animal & vegetable produce.
As Insulin Resistance is multi-factorial, ALL of the potential causes need to be addressed. Once this has been done, IR should be reversed, allowing restrictions on dietary carbohydrate intake to be lifted. See also Can supplements & exercise cure Type 2 diabetes?
The Red flags...The low-carb diet is a temporary patch to ameliorate IR/IGT/Met Syn/T2DM, a bit like replacing a failed circuit-breaker by sticking a nail in its place, to allow the house to function while you fix the problem by buying a new circuit-breaker. Although the house functions fine with a nail in place of a circuit-breaker, you wouldn't want to spend the rest of your life without a working circuit-breaker protecting the house.
So, why do low-carbers seem to want to spend the rest of their lives using a temporary patch to ameliorate their IR/IGT/Met Syn/T2DM?
Long-term use of very-low-carb, very-high-fat, low protein diets is not recommended.
1. Cortisol & adrenaline levels increase due to insufficient glucose production from dietary protein, resulting in gradually-increasing fasting BG level. See How eating sugar & starch can lower your insulin needs and Survival of the Smartest (part 2) - Dr Diana Schwarzbein.
2. If you do too much high-intensity exercise, you may momentarily black-out, fall and hurt yourself. See "Funny turns": What they aren't and what they might be.
3. Some people seem to gradually go bat-shit crazy. See Can very-low-carb diets impair your mental faculties? Read the comments in https://www.facebook.com/TheFatEmperor/posts/1633434020253792. Do the behaviours of Ivor Cummins & Gearóid Ó Laoi seem normal to you?
4. Insulin Resistance is bad, mmm-kay? See Lifestyle-induced metabolic inflexibility and accelerated ageing syndrome: insulin resistance, friend or foe?
5. Insulin Resistance causes carbohydrate intolerance AND fat intolerance, resulting in high postprandial glucose AND high postprandial TG. See Postprandial lipoprotein clearance in type 2 diabetes: fenofibrate effects.
6. Dyseverything elseaemia isn't addressed. See Type 2 diabetes: between a rock and a hard place , Type 2 diabetes: your good signalling's gonna go bad and When the only tool in the box is a hammer.
7. Dietary deficiencies may develop. See Rigid diets & taking loadsa supplements to compensate for them.
8. High-fat diets with no energy deficit result in high postprandial TG's. Postprandial lipaemia is atherogenic. See Ultra-high-fat (~80%) diets: The good, the bad and the ugly.
9. Permanently-high NEFAs (a.k.a. FFAs). See Lack of suppression of circulating free fatty acids and hypercholesterolemia during weight loss on a high-fat, very-low-carbohydrate diet. This raises the RR for Sudden Cardiac Death, and increases ectopic fat accumulation in the pancreas.
There may be more but I'm knackered, so I'm Publishing!
