A low carb-high fat (LCHF) diet is used effectively by many type 2 people. It can give them much better blood sugar control, and helps with losing weight. It can also help some type 1 people. I reduced my carbs and ate healthy fats several years ago. I also took 2000 mg of Metformin each day. I lost a lot of weight and stopped the Metformin when I did not need to lose any more. LCHF helped me very much.
The individual in the diagram is a type 1, and he explains how LCHF has helped his control. The graphs show a before and after LCHF blood sugar control. LCHF has been very effective here. Not all type 1 people need to use a LCHF way of eating, but if the control shows many highs, and/or there is a need to lose weight, then LCHF is worth considering. Perhaps your doctor should be consulted before starting the LCHF routine.
Whilst reading your post I see my experience three years ago. I found it pleasant, euphoric at times, and energizing all wrapped up! Time in range is a big deal to me. The lower graph just feels calmer! LCHF is not for everyone but for those it does work, it can be a boon.
Proposing to someone to change their eating habit is not a popular topic to broach with anyone!
I am type 1 and I do LCHF. Itās the only diet that has been able to help me control my BG. I am also on Metformin and birth control because I have PCOS and am insulin resistant. The only problem I am still struggling with is the inability to lose weight. It is so frustrating, but I am figuring it all out with my endoās help.
Tamra, when I had weight gain and insulin resistance I took 2000 mg of Metformin ER each day. I also reduced my daily carb intake by 30%. It was many months before the pounds started rolling off. After a year on Metformin I had lost all the extra weight. Then I stopped Metformin and increased my carbs. That worked well for more than a year, but recently I have started gaining weight again, and the IR has increased. Now I am taking 1000 mg of Metformin and have reduced my carbs byb 15%.
Ha! As soon as I saw that graph, I immediately thought, thatās @Terry4ās work!!
Cheers!
Thanks, that is reassuring. Iāve only been on the Metformin (2000 MG) for going on two months. Iāve been doing the LCHF since November 2014 (but itās been rocky at times). I keep telling myself it will take time. I know part of my weight problem is the PCOS and I have seen some good results with the therapy Iām on as far as my hormones getting in proper line, but my main concern has always been the fact that I eat well, exercise as much as I can handle, but still am at least 50 lbs heavier than I should be and canāt freskinā lose one!
Patience is key at the moment, I guess. 
Healthy fat suggestions please! Itās so difficult to find high fat items. Supermarket shelves are full of low fat, nonfat goods.
Unsure if Iām doing it right, need help and advice: Breakfast, omelette with cheddar cheese; coffee with cream Is this high fat? Do I add bacon to the omelette with cheddar for more fat so that Iām not hungry? How many carbs do these items represent? If I were having this breakfast I assumed 0 carbs.
Occasionally I have 1 container 6 oz of Liberte Mediterranean yogurt and use the carb count from the container to bolus for the MDI. Iām not on a pump.
Bacon or sausage would add healthy fat. The coffee and cream does have some carbs, so I do bolus for that. Some people experience an increased BG with caffeine.
There is a website that is moderated by several T2 people. They advise all T2 newbies to use LCHF. If a T1 joins the group and is having problems with BG control or overweight, they advise LCHF for them too. I do not like seeing T1ās being advised to eat that way. I feel that T1Dās can eat a more normal diet, use basal and bolus with carb counting, and have good control. If that is not possible, and/or there is overweight, then LCHF can help.
Richard157, in my case, it is how much error am I likely to make if I miscalculate the carbs, the insulinā¦etc. Iāve tried eating around 35 g carbs for dinner, the BGās are sloppy. I think that when I weigh out the foods, if there are 5 errors in the 5 ingredients, they add up. On the other hand, if all 5 ingredients contribute a miniscule amount of carb, BGās seem better. If I have only one item, and it is 35 g carbs, Iāve also had better luck with BG.
Which is the website that you are referring to - LCHF?
The website that emphasized LCHF is:
@lh378 healthy fats would be coconut oil, avocados, tuna, anything with Omega-3. Much more on this website. http://www.goodfats101.com/?gclid=Cj0KEQjwrJ2tBRD13N7T5u7k9I8BEiQA5APAAGp2Xx4HgXwxTHHVUu06Pp5BZaxOyunP5lctAlGDilUaAgNs8P8HAQ
Good luck.

When you eat whole fresh foods, and not supermarket-shelf food, you will know exactly how you are getting the fat in. Eat avocados. Cook eggs in butter or coconut oil, put a pat of butter on your cooked cauliflower/broccoli, full cream in your coffee. etc.
The first thing I saw in this website is that it lumped saturated fats together with trans fats as unhealthy.
Trans fats (margerine) are indeed unhealthy. A great doctor once said to me - āits like eating plastic bagsā. That includes Canola oil and all the processed vegetable oils.
Animal fats including butter, and coconut oil, on the other hand, are saturated - and healthy! fats.
Saturated fats have been REMOVED from the ādangerous for the heartā list, and our body needs them.
But many health practitioners/dieticians and āwebsitesā are very slow to learn this. They copycat from each other.
Please use a more up-to-date source to learn about healthy vs. nonhealthy fats.
I have never understood why the LCHF is the one thing that is pushed. Nutrition and balance are not important?!? They are for me, and I donāt struggle with diet issues. To do my thing each day, I need some carbs. Not a lot, but certainly some fresh produce and sometimes a little rice wonāt kill a T1. In fact, too much fat can be quite dangerous for some folks, Because we donāt know a personās medical history, medical issues, and even the risk of chronic disease based on the family genomics, it is simply unwise and possibly dangerous to recommend ANY diet plan.
Obviously I donāt follow LCHF, there are some nutritious carbs out there. In fact, when I needed to lose some weight I received advice from an RD, who never said to eliminate fat but to limit and make healthy choices. Did that and BOOM, it worked, I continue to follow the recommendation, I feel just fine, my diabetes is managed, and i donāt jones for eats all day long. There is no way I could live on fat alone as the DOC seems to suggest is perfectly healthy. Here is a pretty good up to date source regarding fat: Dietary fats explained: MedlinePlus Medical Encyclopedia
LCHF works for me because I react very strongly to carbs of any kind. But, I do not eat NO carb, that would be impossible. My 25-30g daily carbs come from non-starchy, green leafy veggies mostly. I have been able to reduce my TDI by nearly 40%. Isnāt that the goal, less insulin? But, if you are able to follow a plan that works for you, then BRAVA. More power to ya!
Sarah 
pasture-raised butter and cream are two of my favorite healthy fatsāextremely good for feeding probiotics as well as a ketogenic diet 
Organic coconut oil as well as coconut meat. Avocados. macadamia nuts and oil. organic olive oil.
Hope this helps

I am all powered up from enjoying a bowl of fresh berries right out of the garden 
from my 31.5 years of living with D, I have learned that the less insulin the better.
Sarah
Iām with you, Sarah. I think the less insulin the better, even if you donāt have D. I think too much insulin has all kinds of effects, many we donāt know about yet.
Using LCHF I reduced my total daily dose from 80 to 33. Life is definitely better this way.
