no you cant, when you diet by reducing food intake like that,
your body goes into anti starvation mode by auto reducing your
metabolism. that means what little you eat gets burned down slower
instead, and stored as calories.
your suggested 'diet' is totally imbalanced and will only do harm.
why eat only empty carbohydrates? do you even choose wholemeal
bread with vitamin b3 for energy? dont you think protein and fibre
is necessary for your body too?
why dont you eat 75+% vegetables, lesser meat, lesser carbs? your
body is 80% alkaline. veges are alkaline and meat are acidic. many
ppls diet nowadays are 80% meat, causing acidosis and
lethargy.
there is no need to eat excess starch like white bread, flour,
cookies, noodles, excess of those get stored as calories.
eat more fruits too, they taste nice and are one of the best foods
for your body. alternate the fruits you eat everyday as dif ones
have dif vitamins. fruits with honey and wholegrain cereal in the
morning will give you energy for hours.
if you want to lose weight, avoid eating oily food like indian
food, heavy cream based food, deep fried food, kfc, etc. exercise
enough.
and importantly, how fat you are depends on your chest cavity shape
too. endomorphic, ectomorphic, mesomorphic. (that cavity shape just
below your br3asts, is it a sharp triangle / gradual curve / etc?
if you have a slight gradual curve instead of a triangle you'll
have much more trouble keeping slim.
