Any group exercise ongoing indoor or outdoor? I'm in

hi my name is Cherrie, I'm 41 years old. I wanted to lose weight like 6kg. My current weight is 59 kg. I started to set my goal since 2 years however it doesn't effect me my diet nor exercise. I don't really eat much food during breakfast, lunch and dinner. Hardly I'm eating 2 boiled egg in the morning with cranberry juice or orange juice,, during lunch time normally I ate grilled fish or chicken then at dinner I'm just eating soap with salad. I also do Yoga like 3 times a week as my routine exercise and Yet I haven't lose any weight at all. Would really appreciate if someone out there is been doing group exercise indoor or outdoor, badminton I can join too if any. Let
Me know.
