Weight gain

Chelcie • 28. Mum to 2 girls 🫶🏼 UK
I fluctuate between a 2 stone loss and a 2 stone gain. I can't maintain it when I lose it and I just gain it back again. So far I've only gained back half of what I lost.. But I want to lose the stone again! 
Does anyone have any easy secrets for me that I can try!?
