I can see meds for remission, or very good control - however you want top phrase it, btu drugs for weight loss is a very, very slippery slope, in my view.
I am not a fan of bariatric surgery, having observed more than one person have it, only to find ways to eat themselves back to where they were - even with the restrictions their surgery imposed upon them Not to mention nutritional deficiencies, dumping syndrome, tachycardia, gastric bleeding and a host more.
I have a comprehensive .pdf outlining the major issues, but it is saved to my laptop. It doesn't contain the source, so unhelpful in that regard, but I would not have saved it had it not been from a source such as BMJ, Lancet or such like.
Travellor's right; it was bariatric surgery that triggered Prof Taylor's interest.
In 1995, a study was published which became a landmark: obese patients with T2D had been given gastric bypass surgery and then followed for 14 years. Their T2D went into remission “with surprising speed, even before there was significant weight loss”, and, 14 years later, 91% of them were still in remission—they had effectively been cured of T2D. (

Scientists floated a lot of complicated hypotheses about what was going on. But Taylor had the obvious, simple thought: Immediately after bariatric surgery, and for weeks after, there is of course a sudden and extreme drop in the amount of calories patients are consuming! And it was already well known that, with severe calorie restriction, the body first of all consumes ‘ectopic fat’, fat within organs like the liver.
Taylor hypothesised that this rapid decrease in liver fat would rapidly improve insulin sensitivity in the liver, kicking off the process of remission of T2D.
So he tried something very simple: putting a group of people with T2D on a very low calorie diet ('VLCD')—600 kcal a day—for 8 weeks, mimicking the sudden and severe calorie restriction after bariatric surgery.
“Within 7 days, liver fat decreased by 30%, becoming similar to that of the control group [people without T2D], and hepatic insulin sensitivity [i.e. the insulin sensitivity of the liver] normalized”; by the end of the 8 weeks, liver insulin sensitivity for the people on the VLCD was practically normal and their beta cells’ glucose sensitivity was practically normal—the latter being associated with a more gradual decline, over the whole 8 weeks, in pancreatic fat. (The quote is from

It may well be possible to lose liver/pancreatic fat without doing an initial VLCD-- especially if you exercise, which helps to shift visceral fat; but research shows VLCD gives you far the best chance.
