Hi may,
Are you really cute or just in ur own opinion, i know my mum always said i was.
>Suppose I am on diet and I already reduce my food to a very small amont and I excercise everyday, do I still need to reduce more to loss weight or just stay the same?
Not really, provided you are restricting your calories to a reeasonable level and your burning more than your taking in then a change of your programme should suffice every 4 weeks or so , but your current programme should be varied. You can reduce your calories a bit more if neccessary but wouldnt go too low(under 1000-1250) because then you will hamper your bodies ability to burn calories instead, once it's feasible, do bouts of higher intensity work to raise your metabolism. I don't have and statistics of you to beable to advise you in detail.
Once you get into your training and your doing 30-45 minutes steady state exercise(breathing slightly elevated) and you are warm ask about interval training. You can even break your exercise into 2 parts of the day at this stage, 20 minutes of walking on an incline then later 20 mins of swimming for example
>Another question, when i weight myself after excercise I seem to gain weight what does it mean?
Wouldnt worry too much about this, when you sweat your sweat is held in the clothes, also if you drink water then that could be added weight, the last thing you want to be concerned about is losing or gaining water weight, to keep yourself right drink adequate water, approximately 2 litres per day as you will get some water from food. Water helps transport nutrients and supports functions in the body.
One other thing, weigh yourself once every 1 or 2 weeks, on the same time and same day and eat the same thing you did the last time to get as accurate as possible. For best evidence get body fat levels checked
Hope this helps
