  • Low energy or tiredness

What do these symptoms have to do with my diet?

  • These symptoms may prevent you from shopping, cooking or eating the amount or types of food that you need.
  • Not eating enough or eating a diet with limited variety may lead to many of these symptoms. 
  • Many of these symptoms may put you off exercising, which in turn may increase your risk of chronic conditions, such as hypertension, diabetes and obesity, and worsen your overall health.
