In such condition, histamine rich foods like sardines, tuna fish, certain cheese, certain pain killers (aspirin, diclofenac
etc.) should be avoided. You can take other carbohydrate rich foods including cereals, bread etc. Avoid cheese, butter and milk cream products. Use unsaturated fatty acid like vegetable oils for food preparation. Good exercise to burn calories like aerobics, jogging is helpful. I suggest you to consult dietitian in your area. Take care and regards.
