okay so im trying to lose weight and i heard cold water helps to burn calories and spicy food like jalepenos help speed up your metabolism which burns more calories?
is this true?
how much of a diffrence does it make?

Ice cold water will only make a very minimal difference only because your body has to work a little harder to get the water to room temperature. Spicy food, well it make help, but if you eat too much of it you might have a problem when you go #2.
Try eating food high in protein and fiber, such as lots of fruits and veggies. Just remember, a sign of hunger usually means your dehydrated so drink lots of water

Cold water (ice cold) burns very few calories, and spicy foods build very little metabolism. So, no.
