Why Form is not saving the many to many field value

The problem with the code is that the form is sucessfully getting passed but the model is not saving the many to many field in the Profile models. All the values are getting saved except the food and type. Please help me with the code. Model

class Relationship(models.Model):
    status = models.CharField(max_length =30)

    def __str__(self):
        return self.status

class Food(models.Model):
    food_name = models.CharField(max_length = 80)

    def __str__(self):
        return self.food_name

class City(models.Model):
    city = models.CharField(max_length = 80)

    def __str__(self):
        return self.city

class Type(models.Model):
    types = models.CharField(max_length =80)

    def __str__(self):
        return self.types

class Profile(models.Model):
    user = models.OneToOneField(settings.AUTH_USER_MODEL)
    avatar = models.ImageField(upload_to = image_upload_to)
    city = models.OneToOneField(City)
    fav_food = models.ManyToManyField(Food)
    relationship = models.OneToOneField(Relationship)
    preferrs = models.ManyToManyField(Type)

    def get_absolute_url(self):
         return reverse('chatbot')

    def __str__(self):
        return self.user.get_username()
`

And my Model form is as follow

class ProfileForm(ModelForm):
    class Meta:
        model=Profile
        fields = ['avatar','city','fav_food','relationship','preferrs']

and my view is as follow

def ProfileCreate(request):
    template="profile.html"
    context={}
    if request.user.get_username()=='':
        return redirect('account_login')
    if Profile.objects.all().filter(user__username=request.user.get_username()).count()>0:
        return redirect('chatbot')
    else:

        form = ProfileForm(request.POST ,request.FILES or None)

        if form.is_valid():

            new_profile = form.save(commit=False)

            user = User.objects.all().filter(username=request.user.get_username())[0]
            new_profile.user=user
            new_profile.save()
            return redirect('chatbot')

        context['form']=form


    return render(request,template,context)
