I feel for ya, a loosing weight can be extremely difficult.
What works best for me is my version of an alternate day fasting, basically:
- cut out all the crap / biscuits/snacks etc
- eat sensibly for 3~4-days then 1-day limit to c.500 calories, then repeat.
Along, with 3~4 times/week at the gym doing spin/aqua aerobics / legs bums tums or yoga
The only problem is I have to switch my mindset so that I'm in the mood to do, I'm usually OK getting back into the exercise or the alt day fasting but really struggle to get my mind into doing both each week!
Good luck
