Nobody’s really mentioned sugar in all this and insulin/diabetes. This way of strict low carb eating for me is partly for weight loss and partly to bring blood sugar under control. Previously I’d eat maybe 200g carbs each day which is way too much. Now it’s less than 20g. I think you could easily manage less than 130g which is the recommendation I’ve seen in eating guidelines when you don’t need to lose any weight but 50g is probably even better to stave off insulin resistance. That’s about two rounds of bread!
The evidence is that for diabetes (Type 2) the biggest thing you can do to improve blood sugar control is getting to a healthy weight and doing more exercise. There have been various studies looking at different carbohydrate intake levels whilst dieting and the effect this has... and results wise anything from low to moderate works, but by the nature of weight loss, carbohydrate tends to be the macronutrient that's lowered the most anyway due to the usefulness and necessity of protein (muscle-sparing, most satiating, etc) and fat. So whilst you don't have to go ketogenic, you'll probably end up low to low-ish anyway, and what carbs you do eat should be the whole foods sort that go with a mixed meal nicely.
One thing you don't have to worry about is 'The Insulin Hypothesis' (Gary Taubes, carbs make you fat etc) which will never make it past the hypothesis stage because it doesn't work from an actual biochem perspective, and this has been born out in various metabolic ward studies... some of which were funded by those looking to prove the hypothesis themselves in a spectacular own-goal, as well as the observational evidence of a huge number of populations who eat very high carb diets and have low rates of obesity and great health markers.
