My husband is under lot of stress. he is now over eating especially sweet and dig fridge middle of the night. how can i help him?

Stress management: If the overeating is due to stress, it's best to address the stress itself. Of course, the best way to deal with stress is to avoid it if possible. But it's impossible to avoid completely, so stress management is also important. This can include relaxation exercises, mindfulness, yoga, guided imagery, light physical exercise, & regular breaks from the stressful situation. Therapy can help too.
