Checks out, if your bagel weighs more than 4.5-6kg

A regular sized bagel is 60g of carbs, more or less. My dietician had me target 60-75 grams of carbs per meal with a total daily target of 225-245 for my type 2 diagnosis.

That's a pretty absurd amount of bagel to eat. XD

Here is a really good program for treatment of both type 1 and 2 diabetes. If you follow it you might actually be able to eat a whole bagel.

Yeah, they really are. The only valid medical reason to ever use the keto diet is if you have severe epilepsy, and that is an intervention that is only supposed to be done short term, and under close medical supervision.

At best keto as a general diet generally shows to result in rapid weight loss for only about a year at most, before it plateaus. Odds are any results that come from it are only because the person dropped a few high caloric foods. If your plate is usually full of meat and Mac and Cheese, and you replace that with more meat and, I dunno, buttered veggies, then you're probably eating less calories overall. That would explain the plateau too, because being in a calorie deficit is a state of starvation, and even unconsciously we have a tendency to seek out ways to calm our cravings. That's why plant-based diets are the most effective and consistent for weight loss, because they are naturally lower in overall calories while also providing foods that are known to be satiating.

Obesity in and of itself is the primary driver of type 2 diabetes, and overconsumption of fats - especially saturated fats - are drivers of insulin resistance. So while keto might provide short term symptom relief since your body doesn't have to process sugars, it is about the worst thing you could do for yourself to treat the illness, because you are making the underlying cause worse in the long run, as well as driving progression of cardiovascular disease. Effective, sustainable treatment of type 2 diabetes has to involve, first most chiefly, overall weight loss; but you also need to lower total fat intake, as well as replacing the harmful fats like butter, lard, coconut and palm oils, as well as meat and dairy, with good fats like canola and olive oil, and whole food sources of good fats like nuts and seeds, and avocado.

You can find a solid, real scientifically backed program for both type 2 and type 1 diabetes treatment here.

I want it to be understood, I am not interested in internet arguments when it comes to this subject matter. This is not banal identity politics. This is life and death. I have seen too many loved ones die and all from poor lifestyle habits, including type 2 diabetes. It doesn't need to fucking happen, and I am sick of people flippantly advocating for something that is quite literally the opposite of everything that nutritional science has found to be truly effective. It is grossly irresponsible. Keto is just one more re-branding of a long history of failed anti-carb diets. They never have worked, they never will work, and the only job they need to do is sow enough doubt in people's minds to get them to keep eating all of the things that are killing them. It is the tobacco industry playbook plain and simple.

Anecdotes are not evidence. Even from your own description it's untenable to pin down what your diet even is, other than, "whatever you feel like eating." In that sense it's virtually indistinguishable from the standard American diet itself. Here is an actual nutritional expert on keto:

Should you try the keto diet?

It's advertised as a weight-loss wonder, but this eating plan is actually a medical diet that comes with serious risks.

A ketogenic diet has numerous risks. Top of the list: it's high in saturated fat. McManus recommends that you keep saturated fats to no more than 7% of your daily calories because of the link to heart disease. And indeed, the keto diet is associated with an increase in "bad" LDL cholesterol, which is also linked to heart disease.

Other potential keto risks include these:

Nutrient deficiency. "If you're not eating a wide variety of vegetables, fruits, and grains, you may be at risk for deficiencies in micronutrients, including selenium, magnesium, phosphorus, and vitamins B and C," McManus says.

Liver problems. With so much fat to metabolize, the diet could make any existing liver conditions worse.

Kidney problems. The kidneys help metabolize protein, and McManus says the keto diet may overload them. (The current recommended intake for protein averages 46 grams per day for women, and 56 grams for men).

Constipation. The keto diet is low in fibrous foods like grains and legumes.

Fuzzy thinking and mood swings. The brain works best when the energy source is sugar from healthy carbohydrates to function. Low-carb diets may cause confusion and irritability.

Those risks add up — so make sure that you talk to a doctor and a registered dietitian before ever attempting a ketogenic diet.

Or better yet, just don't do it. It's a dumb fad diet that needs to die.

If you’re wondering we burn them in the order of protein > carbs > fats.

That's not true. Learn more about https://en.wikipedia.org/wiki/Citric_acid_cycle if you want to understand.

I'm aware of the basics of macronutrient digestion and metabolism, and your description is... weird. Would you care to share a source on your claims?

It also needs to be noted, unless you're eating nothing but supplements and highly processed powders, no one eats fat, or carbs, or protein. We eat foods, and virtually all foods contain all three macros in varying ratios. In the real world we get all three together every meal, and if you're not, it means you're following a diet that you probably shouldn't.
