Overfeeding & Glucose tolerance/Insulin Sesnitivity

The new ACSM study really made me think.

It states that short-term overfeeding decreases insulin sensitivity. This insensitivity is still maintained with the addition of additional exercise.

My question is “Will long-term overfeeding also lead to this insulin insensntivity, or is this a short-term overfeeding pehenomenom?”

Is this intolerance dependent on the number of excess calories?

I ask these question becuase I have been overfeeding and I seem to get “sleepy” about an hour after every meal(40/40/20 C/P/F ratios).

Is this a sign that my insulin sensitivity has been affected?

any intellegent responses are appreciated.
