Reducing the spikes is a logical approach. Mainly him T2s and other metabolic conditions, the abnormal spikes are not particularly healthy over time.
With T2, there is usually insulin resistance, which would also cause high circulating insulin levels in your blood (hyperinsulinaemia) which along with the spikes is causing continuous hyperglycaemia, which is higher than normal BG levels. Or T2.
From prediabetes to T2 this is what happens in a lot of people, who have abnormal high spikes and the rollercoaster ride of BG levels continually up and down.
Avoiding spikes, with a low carb approach, that is tailored to you, by you. Is a much more appropriate treatment.
And exercise is also included, with some modicum of good lifestyle choices.
I know through experience, that being in normal or just above normal levels, continually, is so much better for control of your BG fasting levels, your hba1c, and your normal state of homeostasis, which is your body's natural state during sleep, fitness and health.
But as
@Rachox says, I trust my own experience, with how I do it.
Not by so called..........!
