Weight loss with a 4yr old and 4m old

Hello everyone, I’m trying to find ways I can’t lose weight effectively. I’m a mother of two boys, my eldest is four and my youngest is four months. I unfortunately am no longer able to breast feed, in the past I have dieted, weight watched, Adkins, slim fasted and drank green tea. I’m a stay at home mom and so I have been trying to do at home work outs but not a lot is happening. Iv cut out junk food since before my pregnancy, soda and cut way down on sweets. Cutting out meat is not an option...Please help......
