It looks like the Canadian guide chose to copy my plate while using EAT and very little actual science. I like some of it but the whole grain section is just dumb... noodles and bread as whole grains?4 -

Mice:
Collectively, our data indicate that endogenous insulin hypersecretion contributes causally to pancreatic cancer development. This suggests a modest reduction in fasting insulin via lifestyle interventions or therapeutics may be useful in cancer prevention.2 -
The potential role of protein leverage in the US obesity epidemic
The protein leverage model of obesity posits that decreasing the protein content of the diet leads to compensatory increases in total energy intake to maintain an absolute amount of protein consumed. Increased energy intake thereby results in weight gain.
According to data from food balance sheets from the United Nations Food and Agriculture Organization, while the absolute protein content of the US food supply has increased since the early 1970s, the fraction of available calories from protein has decreased by ~1% due to greater increases in available carbohydrate and fat. Surprisingly, even such a small decrease in the protein fraction of the food supply has the potential to result in large increases in energy intake according to the protein leverage model.
Therefore, while the protein leverage effect is unlikely to fully explain the obesity epidemic, its potential contribution should not be ignored.

Our latest RCT paper was just submitted for peer review and now available as a @NutriXiv preprint: "Ultra-processed diets cause excess calorie intake and weight gain: A one-month inpatient randomized controlled trial of ad libitum food intake". -Kevin Hall

Low-carbohydrate diets differing in carbohydrate restriction improve cardiometabolic and anthropometric markers in healthy adults: A randomised clinical trial.
Results:
Of 77 participants, 39 (51%) completed the study. .... The largest improvements in high density lipoprotein cholesterol (HDL-c) and TG and anthropometric changes occurred for the VLCKD group.

Jim Mann’s new study: are high fat diets really dangerous, or is soybean oil toxic?

It would be like claiming all carbs are dangerous when they feed someone a diet extremely high in refined and processed sugar and flours, and applying your results to diets high in fruits and vegetables.0
-
The important takeaway is that these refined foods are harmful. Will be interesting to see if there's a change in posts on MFP in the coming years -- I hope the asinine more-vegetables-less-meat trend dies off at least. Why intelligent people think adding vegetables to their cracker, chicken nugget and treat diet improves diet quality is beyond me but they do!7

Saw this today:
Effects of carbohydrate-restricted diets on low-density lipoprotein cholesterol levels in overweight and obese adults: a systematic review and meta-analysis
Carbohydrate-restricted diets showed no significant difference in low-density lipoprotein cholesterol after 6, 12, and 24 months. Although an overall pooled analysis statistically favored low-fat diets (0.07 mmol/L; 95% confidence interval [CI], 0.02–0.13; P = 0.009], this was clinically insignificant. High-density lipoprotein cholesterol and plasma triglycerides at 6 and 12 months favored carbohydrate-restricted diets (0.08 mmol/L; 95%CI, 0.06–0.11; P < 1 × 10−5 and −0.13 mmol/L; 95%CI, −0.19 to −0.08; P < 1 × 10−5, respectively). These favorable changes were more marked in the subgroup with very-low carbohydrate content (< 50 g/d; 0.12 mmol/L; 95%CI, 0.10–0.14; P < 1 × 10−5and −0.19 mmol/L; 95%CI, −0.26 to −0.12; P = 0.02, respectively).

That follows my n=1. Previously, I was taking simvastatin for low HDL, but was able to improve without carbs. I no longer take simvastatin and my HDL still runs more than double what it was with carbs and medication.1 -

New lower potassium and salt DRI's set -- no more robust then the last best guess but there you are.

I'm thinking this article/study must be up-thread because I read it earlier but I'm not finding it now so am posting. I am interested in following this research.

Their definition of low carb is below 45%, which most would consider moderate or even up to high carb. Its moderate carb level is 45-52%, and high carb is 52+%. For someone like me who eats around 2000 kcal a day, their low carb level is upwards of 900 kcal of carbs or 225g a day. It's a shame they did not actually look at low carb, although to be fair, they might have some who ate less than 100-150g of carbs a day but their data is lost in the moderate carb data.

I liken this to many studies on euglycemic DKA, where they use less than 250 mg/dl or 300 mg/dl as "normal" BG. Umm... not al all. A non-diabetic is not going to be anywhere near that. I have seen evidence that a typical non-diabetic peaks in the upper 100's (average 180 mg/dl) an hour after eating heavy carbs (oatmeal for that study), but not 250 and certainly not 300. This is why it is sometimes valuable to look at the data rather than trusting the labels and categories described in the abstract.1 -

It's BS. There's nothing to follow, IMO, but if anything comes of it - or if the study even gets published - I'll be sure to post if I see it. You might be interested in the follow up post:

Never mind. Thanks for posting the study. I'm interested in following.0

I'm sorry, kpk54. I didn't mean for my disdain for this study in my reply to dismiss your interest. But my response was sincere in that if the study gets published I'll be sure to post a link and if I see anything else in regards to low carb and afib I'll post regardless if I find it interesting or compelling myself.
I hope you have a nice weekend.
