You need to add salt to your foods. Preferably sea salt.
Fat seems to be the dominant macro-nutrient in your diet with all that fast food… so it’s really sounds like a high fat/moderate carb diet. Carbohydrates have a thermal effect. Focus on carbs, primarily a variety of starch and sugar dense foods. Protein is also warming.
Low carb gave me the chills after eating. Since I’ve switched back to a higher carb diet, my hands and feet are always warm and I tolerate the cold much better. I sleep at night with a small blanket and my windows wide open in late October!! I’m burning all day.
It took me a while after I started completely focusing on carbs, probably 2-3 months.
