baking soda to help lose belly fat?

I've seen people drinking apple cider vinegar with water to help with the weight and I've tried it and it's so gross for me, I can't get it down. I've now read that baking soda with water and some lemon juice is suppose to do the same thing and not be gross tasting. has any one tried it? And yes I am eating healthy and working out on a regular basis, I just thought a little extra help won't hurt. I just had a baby 5 weeks ago and the faster I can feel like myself again the better.
