Please don't take diet pills! There is no quick fix for weight loss.
It's not about eating less, it's about eating right. You need to find a meal plan that works for you. You can eat 6 times a day and still be within your daily intake and this will help speed your metabolism, just small portions and snacks between. Always have a big breakfast and don't skip it! When I first started my weight loss journey I followed O2 diet by Keri Glassman, it sure helped me. I now make my own meal plans for the week. Check out bodybuilding.com they have exercise routines and meal plans there as well.
With your exercise I can give you an example of a quick 17 minute HIIT workout below, you can do this fasted before your breakfast in the morning if you like too, you need to do something if you want to lose weight.
HIIT: Do each exercise for 60seconds and walk in place for 20seconds (2rounds is 17min)
(if you have a smartphone you can download a free interval timer or use a stopwatch)
Jumping Oblique Twists
Do at least 2 rounds, more the better!
You can do this in very small space, if you are not sure what the exercises are just Google them.
If you have any questions please feel free to ask.
Just remember your diet is just as important as your workout.
