No wonder - it's such an extreme drain on the reserves what you are squatting at the limit. With my admittedly limited grasp of the mechanics it seems plausible that eating poorly could trigger this - less glycogen stores in the muscles, less ATP available, sudden drop in blood sugar, body racing to replenish. How do yo warm up and what do you eat in the hours prior to a workout? Do you get extra carbs before a workout?Squat: 400x5, 305x5x2. Sudden Onset Diabetes after my first set. It's a real thing I have inbetween heavy squat sets. Unique to the squat. Want to lie down and take a nap.
