This study actually makes sense to me. As a T2D I suffer Insulin Resistance, and there are recent studies that suggest that reducing the adipose fat stored round our vital organs has a beneficial effect by reducing IR for T2D. As it happens, the purpose of this fat around the vitals is to protect them, so e,g, when it gets cold, this fat from the brown cells provides energy for heating for our core bits. And if the temp goes too low, then it prompts us to shiver to produce localised heat. All this warming and shivering uses up this visceral fat, and so indirectly would help to reduce IR. That's my theory anyway,
And not an exercise bike in sight.
PS my radiators have thermostatic valves fitted, so I only have a central thermostat to protect the boiler So meanypuss here turns the heating off asap since it is costing me £240 a month to run.
