Low-carbohydrate high-fat (LCHF) diets are a highly contentious current topic in nutrition. This narrative review aims to provide clinicians with a broad overview of the effects of LCHF diets on body weight, glycaemic control and cardiovascular risk factors while addressing some common concerns and misconceptions.
Blood total cholesterol and LDL-cholesterol concentrations show a variable, highly individual response to LCHF diets, and should be monitored in patients adhering to this diet. In contrast, available evidence from clinical and preclinical studies indicates that LCHF diets consistently improve all other markers of cardiovascular risk—lowering elevated blood glucose, insulin, triglyceride, ApoB and saturated fat (especially palmitoleic acid) concentrations, reducing small dense LDL particle numbers, glycated haemoglobin (HbA1c) levels, blood pressure and body weight while increasing low HDL-cholesterol concentrations and reversing non-alcoholic fatty liver disease (NAFLD).
This particular combination of favourable modifications to all these risk factors is a benefit unique to LCHF diets. These effects are likely due in part to reduced hunger and decreased ad libitum calorie intake common to low-carbohydrate diets, allied to a reduction in hyperinsulinaemia, and reversal of NAFLD. Although LCHF diets may not be suitable for everyone, available evidence shows this eating plan to be a safe and efficacious dietary option to be considered. LCHF diets may also be particularly beneficial in patients with atherogenic dyslipidaemia, insulin resistance, and the frequently associated NAFLD.

Cherry picked evidence, you can find evidence for any diet if you look.
"you can find evidence for any diet if you look"
Agreed, the evidence for the so called high carb balanced diet, is everywhere we look. Around half of adults overweight or obese, 400 million+ diabetics in the world, 90% type two. Could there be more evidence of the failure of the so called food pyramid.
Anyway anon, please try harder if you want to wind me up.

You think everyone in world on high carb diet is obese, diabetic? Not in rural Africa, with respect my friend.
Now that's where your ilk go wrong, did I say everyone in the world? And I hear SA has a very high obesity and type two problem. As for rural anywhere, I am sure there are lots of slim people. Probably eating real food, rather than supermarket factory made junk.
Your growing on me, see you soon. Tell me, if you think you are right, and you are an honest person, why do you hide your identity.

You are correct in that it is avoidance of junk but Africa is not obese as is West. High carb foods are a staple in areas that are not poor or starving, yam ,taro, rice, beans and lentils, even north Africa we are eating flat breads and couscous as staple but still not obese like USA and UK. It cannot be carbs from real food causing obesity. It is easier to comment as anonymous.
"You are correct in that it is avoidance of junk" so we agree on that point. "Africa is not obese as is West" we agree on that point. "north Africa we are eating flat breads and couscous as staple but still not obese like USA and UK" perhaps these people work harder and are less sedentary, I suspect these people are not eating high amounts of candy, chocolates, shop cakes and other junk. People in India eat a lot of carbs and obesity and type diabetes rates are going through the roof. What are views on that situation?
Eddie
Well this point is does eating high carb but not junk food high carb result with obesity? In China this also is happening, rural people move to cities and get the Western diseases. India also, lots of weight gained when people move to cities, more food everywhere,easy and cheap to buy. True that city jobs today are more office or production factory type where you stand at a station. You have to ask what has changed in India and China before and since this happened. It cannot be high carb because that was so for years.
I agree with everything you said above. I have never said carbs cause obesity or type two diabetes. But once an overweight or even thin type two, they have to be reduced big time. Medication does not come close to what a low carb diet can do. I ate carbs for 57 years until I was diagnosed a type two diabetic. I am sure you are aware there is far more to type two diabetes than carb intake. As you said as more rural people head for the cities, the more junk they eat. Look at the so called 'primitive' people of Australia, the Aborigines. Arguably the toughest hardiest people ever, until they got the white mans diet.
Eddie
Yes, nice to end on some agreement, look at the wonderful ways food is chosen and eaten in this wide world and take what you can from it. Thank you for this debate!
And thank you Sir/Madam and the very best of luck and health to you and yours.

Finally, something what an anonymous person said didn't sound stupid or offensive.Yes, not everyone eating a lot of carbohydrates gets fat or develops a diabetes. Is it any comfort for anyone with a metabolic disorder or a diabetes? Low-carbing allows food restrictions without usual hunger and "available evidence from clinical and preclinical studies indicates that LCHF diets consistently improve all other markers of cardiovascular risk—lowering elevated blood glucose, insulin, triglyceride, ApoB and saturated fat (especially palmitoleic acid) concentrations, reducing small dense LDL particle numbers, glycated haemoglobin (HbA1c) levels, blood pressure and body weight while increasing low HDL-cholesterol concentrations and reversing non-alcoholic fatty liver disease (NAFLD)." What is wrong with the idea that a patient may give such diet a try while being monitored by his/her GP? Hunger-reducing drugs didn't prove to be effective, gastric by-pass has risks and complications, eating big volumes of fiberous foods leaves many stuffed and still hungry. Why not?
Second rate journal - should that say narrow minded report?
