Vasodilation actually facilitates heat loss, by bringing blood closer to the surface of the body, where the heat can more readily move from the body to the surrounding environment. The body employs vasoconstriction to retain body heat, for the opposite reason. Thus even though vasoconstriction can cause peripheral coldness and pallor, it's only because the body is conserving its heat in an attempt to prevent the core body temperature from dropping.
There are two ways that food can heat the body: one by increasing metabolism as in ingestion of too much iodine or by decreasing heat loss. Some things ingested like alcohol give the feeling of warmth as they increase blood flow to the skin and vasodilation, but that is the sensation of heat leaving the body.

Vasodilation refers to the widening of blood vessels, increasing blood flow and heat loss through the skin, which helps to cool down the body during hot conditions. Vasoconstriction, on the other hand, is the narrowing of blood vessels, reducing blood flow and heat loss through the skin, which helps to retain heat and warm up the body during cold conditions. These processes play a crucial role in temperature regulation by adjusting blood flow to the skin to maintain a stable core body temperature.
No, but instead it gains heat energy
No. They generated heat.

Peripheral vasodilation is the dilation of the veins and arteries of the periphery. This will lower blood pressure and provide less resistance for the heart to beat against. It also makes the capillaries of your face come to the surface and show you to be flushed.
More blood goes to your skin to create heat loss. This is where your blood vessels dilate (expand). This is called vasodilation.
They will allow the blood vessels to widen so that more heat loss can occur through evaporation. This is vasodilation.

Mammals lose heat because they are often warmer than their surroundings, it is a law of thermodynamics that heat flows from warm to cool.
The Adipose Connective Tissue insulates against heat loss and provides reserve fuel.

Blood carries many things including heat, so where blood flows the heat from the body follows. Vasodilation and Vasoconstriction is the act of opening or closing the lumen of the blood vessels. Opening the vessels (vasodialtion) to the skin allows the heat to be carried to the surface of the body where it escapes into the atmosphere. This is why you go red at a medium level of exercise. The extra heat produced is corrected by increasing the blood flow to the skin allowing heat to dissapate and intensifying the rednes. In cold weather flow to the skin is decreased through vasoconstriction meaning that less heat is lost to the atmosphere.
