Hi Todd,
Thanks for the interesting post. Mg can be helpful for weight loss 
because Mg supplements can increase insulin sensitivity (1). I have 
noticed that I require more Mg when I eat carbohydrates. Otherwise I 
become constipated. I have supplemented at least 250 mg of Mg/day for 
the last ~15 years. When eating significant carbohydrates I have to 
increase that to 500 mg/day. As long as I keep my Mg intake congruent 
with my diet, I don't seem to have any signs of insulin resistance.  On 
a few occasions I have not increased my Mg when eating carbs and 
constipation quickly reminds me that I need more Mg. Insulin resistance 
would inhibit movement of insulin sensitive amino acids into the cells, 
which may also suggest why you were very hungry on a high fat, high 
protein diet.

best wishes,
Ron
