Curries – cooling?

I made massaman curry last night and just ate some of it for lunch. My temps after my usual lunch of a hamburger or all beef hot dog with raisinets for dessert are usual in the low to mid 98’s (good for me) but my temp after the curry was only 97.7. I made mine with potatoes, canned coconut milk, chicken thighs with skin and visible fat removed, onions, garlic, ginger, lemon zest, a little thai fish sauce, and about 5 dried spices. I salted it to taste ate it over basmati rice and had quite a bit of it since in was very delicious. Anyone have an idea why it was not warming? Is it the chicken or are spices not good for metabolism? I had a peach for dessert and just a few raisinets (much less than normal). Maybe I need to stick with beef and copious amounts of raisinets.
