Pregnancy while overweight

Had anyone successfully lost weight during pregnancy? I am 5 weeks pregnant. I realise I should have lost weight prior to getting pregnant but I'm here now. I don't mean drastically reducing calories or following any fad diets. I'm just looking for someone to give me any tips of how they safely lost weight during pregnancy alongside any food aversions etc. I am posting anonymously because I feel that this post may elicite some harsh responses.
