you can use all the supplement you want but without a sound nutrition plan. It will never work. At least start out eating 'cleaner' and more frequent,
1) cleaner in the sense of lesser processed food , stick to whole foods
2) lesser refined carbs (bread, sugar) more complex carbs (it helps keep you fuller)

to gain muscle weight, you need to be at a caloric surplus.

workout tirelessly ? how ?

to obtain a 'lean and hard'    body takes times and much trial and error. not an overnight task.

u can take rice but try having it post workout instead. yes increase fibre intake aka more vegetables and MORE protein. and please DON't neglect the healthy fats !! like whole omega-3 eggs, nuts, olive oil, macadamia nut oil etc just to name a few. contrary to popular believes, fats don't make u fat.
