Eating only 2 wholemeal bread, 1 small pack of jacob's, 3 ordinary biscuit & 4 digestive biscuit for whole day. is it healthy? my friend is on diet.

NOT healthy at all!: I have no idea what jacob's is but everything else your eating is bread/ starches. The healthiest diet (for both weight loss and good health) is to eat mostly vegetables & fruits with healthy protein and to minimize starch. You don't seem to be eating any veggies/fruit & eating mostly starch, the opposite of a healthy diet! My favorite diet is Dr. Fuhrman's Nutritarian- see http://bit.ly/1dHW9hT
