I've lost 17 kilos over the past 4 months doing the "Dieta 10" under the care of a dietician in Tenerife north and losing 1 kilo per week more or less.
So in that time I haven't touched:
wine or any alcoholic drinks, sugar, sweets, pasta, bread, butter, potatoes, tomatoes, whole milk, cream or yogurt, sweet fruit and vegetables (eg carrots or yellow yams).
I have been able to eat some green vegetables: lettuce, cucumber, Swiss chard, cabbage and a gradual introduction of other vegetables in small quantities.
And there is one bread that I must eat daily
(here's a slice) which is bought in a pharmacy and is taken ...2 of these small slices...at breakfast with some turkey ham.
There are also herbal diuretic infusions to take 3 times a day before meals and another herb tablet after meals. Two snacks per day are obligatory, mid morning and mid afternoon.
A liquid vitamin is taken every morning.
This is basically a high protein diet....not risky like the Atkins diet....and so meat, fish, poultry can be eaten in endless quantities. A typical lunch will be fillets of hake (merluza) with chopped lettuce and cucumber, dressed with a little olive oil and vinegar, or a steak or chicken breast. I was getting up to having lentil and vegetable stew but then my weight loss reached a plateau and didn't go down for 2 weeks so I was put back to lettuce, cucumber and asparagus as my only vegetables.
Yogurt is okay as long as it's the no fat no sugar type, as well as 1 glass of skim milk per day and 250 grams of fresh goat cheese per week (I buy the best....Maxorata from Fuerteventura, sold in Mercadona.) Three eggs per week but you can add more egg whites if you want, making scrambled or in an omelette.
So without having to go on this diet ....(I go once every week to the dietician for a weigh-in and a body fat check).....you can drop pounds and kilos by cutting out all fattening things, including some vegetables such as potatoes, avocados and fruits such as bananas, grapes, oranges and others which are high in sugar.
A baked potato contains more sugar than a potato which is steamed or boiled. (It's higher on the glycemic index.)
So you can also lose weight by steaming vegetables and baking meat and fish rather than frying.
So I would suggest that as well as bread you could cut out potatoes, all alcohol, pasta, bananas, grapes, oranges, butter, cream etc.
After a month you should have lost some weight and can enjoy the Christmas treats

Good Luck!
