Carbohydrates lead to weight gain because they are really complex sugar – tyhey have chemical formulas in a different although equivalent ratio to C6H12O6 – so they are broken down into it and stored on you as weight for future energy food if you do not burn it off. Pizza, spaghetti, macaroni cheese and lots of bread and pasta is a staple in many Americans diets and they are easily obese from this – although they should be eaten in moderation, not cut out like the silly industry says to wash gluten free food down the public

kiwi's are funny 🙂 but alas for 'evidence' – the LCHF obviously works for some people what more evidence does anyone need unless they have to satisfy some regulatory board.

Ketogenic is working or me. I eat all I want of things I like and I'm not hungry. The pounds are falling off like crazy.The last part of that sentence is amazing because I've had an absolutely ravenous appetite for 50 years!

I lost 60 pounds in 8 months going low carb. Low calorie gained me 30 pounds. Show me a weight loss plan and I will show you how carbs are not part of it.

Seriously…if u got a candida problem u may wanna try the vegan raw foodist approach except becareful wit fruit and food combining. Dont mix carbs with fats in a meal if u got insulin resistance issues. Bloating is abnormal…its a sign u are not digesting well and may have candida or some bad bacteria overgrowth. U could also try some paleo diet temporarily to help wit adjusting back to carbs…

She is very thin, so it kinda puts me off, plus she doesn't sound convincing. Plus this diet has made me lethargic, and I put on weight and waist circumference. It also makes  you think constantly about what you can and cannot eat. THIS IS WRONG!!! Now I am sure that LCHF is NOT the way to eat. It's a fad!!

I've tried this, does not work for me. 
I was always hungry although I was stuffed with meat and veggies to the top. 
The same symptoms people here say they have on a high carb diet I had on a low carb diet.

My story is ,after two weeks of low-carb diet, i lost couple pounds my sugar in blood decrease from 20 to 7.8

Consuming carbs and protein in moderation will kill you over the space of about 100 years.

Urszula Forenc June 28, 2020 - 4:01 am

I'm on LCHF for 3 years now, great way to eat.

I've tried both high carb low fat and high fat low carb diets. HCLF wasn't working well for me as I was always hungry and even when I ate a lot of food I became bloated but the hunger was still there. I was starting to gain weight eating only 2000 kcals per day. The weight gain was all around my belly which is not a good sign. The blood work tests confirmed that my colesterol was through the roof and my blood pressure was very high. I felt lethargic and my mental focus was short lived. I knew something had to change and had been reading about low carb diets so I decided to try it. The past 11 months have been high fat low carb and my health has never been better. The first thing I noticed on high fat was my circulaton seemed to improve, my energy levels and mental focus increased while remaining stable throughout the day without the need for caffeine. The belly fat melted off within about the first 3 months and for the first time in my life my abs began to show. Strangely my calorie intake has gone up to around 3500kcals per day but I'm leaner than ever. My doctor was warning me not to do a high fat diet but when he saw my blood work results he was shocked at how much it had improved and the blood pressure returned to normal. Everybody keeps saying I look so much healthier these days and I certainly feel it too. I must admit I was sceptical that it would work and eating so much fat seemed against everything I had been brought up to believe, but it worked and still is working. I say don't knock it until you've tried it. I think I have given both diets a fair trial and 'for me' high fat low carb wins hands down.

My grandmother was a diabetic who had a friend who was also a diabetic. Her friend used to tell my grandmother not to eat rice, that rice is the most harmful thing for a diabetic. She'd told my grandmother to substitute rice with meat and encouraged her to eat animal lard as well. It was normal for their family to buy half a pig every time they go shopping for food. Her son and grandson were both fat. Anyway, not long after my gradmother moved to live in a place quite far from her "low carb" diabetic friend and it wasn't possible to see her friend often. About 10 years later (back in the 90s), my grandmother became a vegetarian for religious reasons and stopped eating meat altogether. The side effect was that her blood sugar, to our surprise and contrary to what her low carb guru had always feared, was always in the normal range and so all was well for my grandmother with her vegetarian diet. But at about the same time, we heard news that my grandmother's friend (who avoided rice and all forms of carbs and ate meat in place of rice) had both her feet amputated. Consequently she became bed bound for about 3 more years before she finally passed away. Her son, who also ate like her (avoided rice and ate lots of meat, had a stroke in his early 50s and was completely paralysed and bed bound for years. As of today, we're not sure whether he is still alive or not because it has been more than 15 years now since his stroke incident and we have not heard of him.

It seems the guru friend of my grandmother who taught that rice is evil and meat is good for diabetics didn't know what was coming for her by avoiding rice and carbs completely and ate huge amounts of meat and lard instead for so many years. So, people really need to question the long term harm that a low carb diet can do to the body. The key word is "long term". All these so-called low carb dietitians and doctors don't really have long term data to show you the harm of a low carb diet on the organs of the body. They're all too passionate and too rush into the things they believe, which is hardly like what a real scientist should be like, and the consequence could potentially hurt the love ones of many families who believe in their "professional" speeches..

In comments reportedly made during a press briefing for her new movie SALT, Angelina Jolie discussed her bad experiences with a vegan diet.

“I joke that a big juicy steak is my beauty secret,” said Jolie. “But seriously, I love red meat. I was a vegan for a long time, and it nearly killed me. I found I was not getting enough nutrition.”

This is not an uncommon complaint among former vegans; the limitations of the diet require extra diligence to make sure you get proper nutrients.

Like previous posters, I would ask her about the voluminous amount of evidence linking animal consumption and chronic disease of all kinds. Conversely, what studies link whole grains and chronic disease, not counting celiac or wheat allergies. Yes, you can lose weight on Atkins, but at what cost to your overall health??

I became super healthy and fit on a 90% carbs diet have been eating like that for 14 months now, 3000-5000kcal/day. Best thing ever happened to me. But: How can a completely different diet (like no carbs + huge amounts of fat) seemingly bring about some health benefits that appear quite similar?

It seems that there is a 'local optimum' in 'macronutrient space' in the region of low carb+high fat+low protein, mathematically speaking, in addition to the other optimum at very high carb+low fat+low protein. Assuming that you can stay in ketosis or close to it for your entire life.

Has anyone ever compared high carb and no carb diets? I mean things like like participants HAVE TO eat say 5000kcal/day and HAVE TO burn say 1500kcal/day through exercise for a whole year?
Or like putting participants on a high carb vs ketogenic diet for say 25 years?

Really pushing it in terms of calory throughput/physical performance or time should reveal how the two approaches really compare.

I love this video. It gave me the confidence of trying this LCHF diet. I have been on this diet for nearly three weeks. Being a diabetic on insulin, my obvious daily benefit is my blood sugar is much better controlled with no swings of high and low.  My right hip pain has disappeared. Also my leg jerks at night have gone! The only problem I found is when I walk upstairs my legs feel tired. I can still walk as long as I like on the flat ground without any problem. Thanks Caryn for being the brave dietitian.

Finally a Dietician who thinks outside the square.

presjo June 28, 2020 - 4:01 am

that goodness, some REAL nutrition info in NZ. sick and tired of reading books, and posters in my doctors office telling me to eat 10 serves of grains and carbs per day.

I'd love to see people putting some evidence up, like real research say, instead of half baked stories.

Incident heart failure is associated with lower whole-grain intake and greater high-fat dairy and egg intake in the Atherosclerosis Risk in Communities (ARIC) study.

Are Grains Making Us Fat?
It's true that since the 1960s grain consumption has gone up, but overall we eat a lot less than we used to.  We have never gotten back up to the nearly 40% of calories from grains that we consumed in the early part of the 20th century.

You'd have to wonder how we all survived, seeing as whole grains and starchy foods are the historical staples of all large successful populations around the world.
Historical Examples of Grain-Based, Starch-Based, Diets
Barley – Middle East for 11,000 years
Corn – Central and South America for 7000 years
Millet – Africa for 6,000 years
Oats – Middle East for 11,000 years
Sorghum – East Africa for 6,000 years
Rice – Asia for more than 10,000 years
Rye – Asia for 5000 years
Wheat – Near East for 10,000 years

To any dietitian watching this clip, please note that the first comment "I'm one of the good ones" – meaning dietitians, was said in context with what was mentioned in several presentations before mine. Some of the presentations at this conference included mention of the gross opposition that they had faced by Registered Dietitians across the globe, relating to the low carb, high fat (LCHF) philosophy. My comment was said as a means to add humour to the start of my presentation. I did not mean that all dietitians are bad, but rather that in the context of previous comments on their actions regarding LCHF, that I was one of the good ones. Just thought I wanted to clarify that for anyone who might have taken offense.

Very informative talk for anyone interested in low carb high fat diet.

MuffinMan June 28, 2020 - 4:01 am

Where should the majority of my fats be coming from?

charlottesmom June 28, 2020 - 4:01 am

Low carb for me = arthritis in my left knee disappears! :0)
