Well its not really healthy to be overweight ...
imo its not really a hindrance for hrt but there are a few SRS surgeons who have BMI restrictions ...
You might think about a change in diet towards more vegetarian food.
Many vegetables consist mostly of water.
So for example having an apple or a piece of pineapple as snack does not add much to weight.
Just ba a bit careful with coconut or coconut juice

. Because of fat.
Since you like food its possible to make changes and still keeping tasty food.
Its simply different.
whole grain bread with various toppings and salads could be an idea ...
selfmade soups ...
all in a healthy variety ...
avocado oil is said to contain ingredients that do not go predominantly to the belly ...
avoiding carbonated drinks and drinks with a high content of sugar should also be a good idea, preferring bottled water and tea instead ...
warm tea can also help feeling full ... maybe with natural sweetening like honey, or brown sugar ...
