A woman on Instagram claims to have lost 65 lbs (29kgs) in a year, without setting foot in a gym.
Tiffany, who uses Instagram with the username My Adventure to Fit has almost 14,000 followers.
Her account documents her fitness, and in recent days she has shared 'before and after' shots of her body.
Tiffany told Popsugar:
When I would go shopping, I would always buy the XL of whatever it was and never try it on because I didn't want to face that it might have been to small for me.
I decided to 100 per cent commit to being DONE with 'junk food'.
No more candy bars, sodas, or other things alike.
I went dairy-free and gluten-free.
In addition to dietary changes, she opted to exercise at home, doing 'Insanity Max 30' work outs.
She also advocated avoiding fad diets.
Eating healthy and keeping your body moving is what works.
Starvation diets, diet pills, wraps — they're all temporary.
Solving the real problem will give you the real and permanent solution.
