Does this do what you want?
% create a structure with empty fields
S.A = 'x' ; S.B = [] ; S.C = 1:5 ;
fn = fieldnames(S)
tf = cellfun(@(c) isempty(S.(c)), fn)
S2 = rmfield(S, fn(tf))

You can try like this:-
out = {t(~cellfun(@isempty,{t.places})).places};
t = cell2struct(out,{'places'},1);

@Stephen Thank you very much! This worked like a charm :)
How I should I then save the file? As I noticed that when I clicked on the save button, it seems to change the way the file is saved and messed up the array structures in the file.

% Create struct with empty fields.
s.a = 'notEmpty';
s.b = [];
s.c = '';
s.d = 12;
fields = fieldnames(s);
sOut = rmfield(s, fields(structfun(@isempty, s)));
sOut =
struct with fields:
a: 'notEmpty'
d: 12
