Unless their is an underlying medical or physical condition then no.. it's not a struggle. It's a lifestyle choice and choices they make. It's choices in what they eat, what they buy, how much they eat, and what they choose to do with any free time they have. They can sit and watch TV all day or.when off work or.get up and go do something.
And for most people it's not this drastic change in lifestyle that's required, usually just being smart about what you put in your body and a little discipline.
My mother wasnt happy with her weight. She is always active, cutting grass, gardening, taking care of her mother, but at 62 she was getting pudgy.
She stopped eating or drinking anything with processed sugar. Only lifestyle change she made. She lost 25 pounds in 5;months.
That's it.. all she did. No trips to the gym, no salads every meal, no extra walking or running, just 1 little simple dietary change.
But she had 1 thing most don't, self discipline. She said the hardest part was giving up her sweet tea. Lol She used a sugar substitute to sweeten it and complained it didn't taste the same.
It is pretty much that simple. Lifestyle choices are what make the difference. Personally I could care less if someone is overweight or not.. that's their business. But don't eat Yugo food and expect to have a Ferrari body. It ain't happening.
And yes, I do understand that some are genetically predisposed to store fat more easily than others, that's why diet and watching what you eat is so important. It can be a little harder for those folks but if they do just a little research and exercise some self discipline then weight won't be a problem.
Blame anyone they want, food manufacturers, doctors, genetics, but ultimately it's the person in the mirror making the choices.
