Losing weight is a struggle for most people. They have to spend months, sometimes years, wrestling with a number of diet plans and fitness regimes before they finally see the pounds start to fall off. But it turns out that losing weight could be a lot simpler than most of us knew.

This grandma from Sydney, Australia, managed to shed a whopping 68 pounds in just three months WITHOUT exercising.

One of the reasons that so many people struggle to lose weight is that there are so many myths about weight loss out there. Some of the most popular myths are that all calories have an equal effect on your body and weight loss itself being a linear process (it’s not).

Ana Reyes decided to take action about her weight after she was shocked by her appearance in a picture of four generations of her family.

Recalling her size, the mom-of-two said to Daily Mail Australia, “I couldn’t believe how I looked. At the same time I couldn’t walk up stairs, I couldn’t paint my toenails, it was awful,” she told Daily Mail Australia.

“I didn’t socialize, I didn’t have many clothes that fit me, I was totally embarrassed.”
