I haven't read all the responses but this is what I got out of your original post,
It doesn't sound like your husband is all "gung ho" about the working out. But you are so don't let his choices become YOUR choices. You can make your own choices that suits you the best. If you feel that a workout schedule suits your work and life schedule then do it and simply inform him. I wouldn't give him a chance to make the excuse or to deter you from making your own choices. If it totally makes sense to you and it isn't impeading on your personal life then there's no reason why you can't do a workout you want to (like the boot camp)
As for eating right, just make sure you are making good choices and if he hums and ha's about it then tell him he can make his own food, this is how you are choosing to eat now. I would just keep quiet about the whole weight loss thing with him honestly if he finds every opportunity to make an excuse. It seems once he bashes your idea to get fit, you make that your choice too, so just do what you feel is right for you and come here for the support.
It will take time for him to adjust and he might get his back up for a bit, but stick to your truth. It's YOUR body, YOUR health and YOUR life, you can't make him join you that's up to him.
Good luck hun
