Your DH aside....
If you want to lose weight (for you), I can recommend a very easy way to do so. For me, faddy diets didn't work. I went from a size 16/18 to a size 8, by doing this:
1200 calories a day
Walk 4 miles a day
That's it.
It only took 4 months. I started on January 1st, and by the 1st May it was all done.
Now, I can't go hungry! So you need to stock up on low cal snacks.
Eg.
Breakfast: Crumpet and butter, plus coffee.
Snacks throughout the day:
Caramel rice cakes
Chocolate rice cakes
Weight watchers fromage / yoghurts
Quavers
Wotsits
Low fat cheese triangles
Melba toast
Ham
Chicken
Fruit
Crumpets
Cup-a-soups
Lunch: Adsa American ranch salad, with cherry toms, cucumber, red onion, 3 slices of thick ham, ranch dressing (takes a lot of eating!), followed by a pack of wotsits and a yoghurt.
Dinner: whatever you are cooking for the family, minus the carb bit (replace potatoes with side salad)
Supper: Ryvita with cheese triangle, packet of quavers
I seem to be eating all day! I am never hungry.
Set up an account on Myfitnesspal. Log everything you eat (and drink).
If you enjoy fizzy drinks, get zero sugar versions.
If you start tomorrow, you could be your goal weight by as early as August/September.
Do it for you though, not for him!
