Eating a balanced and healthy selection of food on a daily basis can affect a lot more than just your body weight and shape. What we eat can affect our moods too! A diet full of sugar not only can damage teeth and affect weight but can lead to energy highs and then dramatic lows where you have no energy and you may feel low or moody. Not eating enough food or drinking enough water can also cause tiredness and mood swings. So look after yourself eating well and feel well!
