Does being overweight make your drive go downhill?

Yes it can, The type of diet you are consuming can affect your ual life eg: A healthy diet including lots of fresh fruits and vegetables can make you feel more energetic because you are eating food that are high in anti oxidants and low in GI for long lasting energy. If you are foods that are fatty and sugary you won't feel as good and it could potentially make you less active as the high levels of GI can make you burn out quickly. My answer is not the best answer i have ever written but it is something for which i have learned through Health cl :)
