WRT hands being cold I often have the opposite problem. My hands get too HOT and start sweating, especially if there is little-no wind, then I get to the summit where it is windy and my gloves are soaked from the inside and my fingers get cold then due to the wind. That's what happened to me on Spread Eagle Peak last Winter. It's a Catch-22 for me in deep/steep snow, gotta keep gloves on in case I slip and put my hand down in the snow, meanwhile my hands are cooking inside my gloves!
I've found that I am a very "exothermic" person.
I have the same problem, I stay super warm and I struggled for years to find a glove system that I didn't soak. My solution has been to find thin breathable gloves. I like thin fleece gloves that aren't windproof and I also like uninsulated shells. If I'm hiking in snow on a nice day, I like to hike in my shells. I downhill ski all winter in lightly insulated cross country ski gloves. My current winter hiking setup is arc terx fleece gloves with REI taped mitten shells. I keep a pair of OR alti gloves in my pack just in case.
To the OP I'd tend to look at your glove system or your other clothing system. The physiology behind cold hands has to do with in the early stages of hypothermia your body shunts blood from your extremities to your core to preserve the vital organs so if you keep your core warmer, your hands should stay warmer. I'm not sure about nutrition, but I wonder if you could find a vasodiolator like nitro or maybe viagra? I kinda doubt you could get anyone to prescribe them for you, but who knows.
