I understand your feeling but I would like to tell you that doing gym is a very good habbit but you don't need to take any kind of medication for slimming. You can take green tea instead with 1 tea spoon of honey. Be dedicated with the gym. Take fat free diet and that would do. Thank you
Your BMI is 32 and normal lies around 22 which means your weight according to your age and height should be 65-70 kg.
Obesity is responsible for diabetes and heart diseases hence start following healthy lifestyle to prevent complications in future.
First wake up early and start yoga and brisk walk for 45 min daily.
Asanas like shalabhasana, pavanmuktasana and sun salutation would be helpful.
Second do not rush to loose weight as crash dieting can be disastrous at times. Reduce half kg weight every month.
Third medicines like arogyavardhini, medihar guggulu help only with ayutvedic consultation and healthy lifestyle change.
