That doesn’t say that eating fat causes diabetes… it suggests that being fat causes diabetes.

The Indiana University study showed a big drop in medication use among people on the keto diet. About 60% of those using insulin stopped needing it entirely. Medication use went down a lot in the keto group, unlike the control group where it stayed the same or went up. Overall, 47% of people on the keto diet achieved remission or reversal after one year and 38% after two years. In the control group, 7-10% of people achieved remission or reversal after 1-2 years.
When comparing the studies(keto and low calorie) the results were pretty much identical with regard to diabetes remission or reversal.

Eighty-four community volunteers with obesity and type 2 diabetes were randomized to either a low-carbohydrate, ketogenic diet (<20 g of carbohydrate daily; LCKD) or a low-glycemic, reduced-calorie diet (500 kcal/day deficit from weight maintenance diet; LGID). Both groups received group meetings, nutritional supplementation, and an exercise recommendation. The main outcome was glycemic control, measured by hemoglobin A1c.
Results
Forty-nine (58.3%) participants completed the study. Both interventions led to improvements in hemoglobin A1c, fasting glucose, fasting insulin, and weight loss. The LCKD group had greater improvements in hemoglobin A1c (-1.5% vs. -0.5%, p = 0.03), body weight (-11.1 kg vs. -6.9 kg, p = 0.008), and high density lipoprotein cholesterol (+5.6 mg/dL vs. 0 mg/dL, p < 0.001) compared to the LGID group. Diabetes medications were reduced or eliminated in 95.2% of LCKD vs. 62% of LGID participants (p < 0.01).

A reduction in the use of glucose-lowering medications subsequent to KD has been observed by several studies. In a study by Saslow et al., 60% of participants could discontinue sulfonylureas and/or DPP-4 inhibitors, and 30% metformin after KD, but none of the subjects could do so in the control group [25]. Tay et al. reported a greater reduction in glucose-lowering agents following KD compared to the control group (p=0.02) [29]. At the 1-year follow-up, Hallberg et al. documented a significant reduction for all diabetes medications in participants of the KD group compared with the usual intervention [24]. Specifically, the overall prescriptions (not including metformin) dropped from 57 to 30%; insulin therapy was reduced/interrupted in 94% of users, sulfonylureas were discontinued in 100% of users, and metformin decreased slightly (from 71 to 65%, p=0.04)
