Hi Nancy - unlike you, I'm not overweight. I work out about 60 min a day and eat an extremely careful diet formed over years of experience and knowledge. As recently as 10 years ago I was laughed at for suggesting to obese coworkers and colleagues that they might want to consider diets without sugar, wheat, and processed foods/preservatives. Now this is covered in Mayo Clinic and the Harvard Health Letter. Recent research shows that consuming refined carbs does contribute more to weight gain that eating equivalent calorie amounts of protein and/or fat.
I don't go to the doctor except in emergencies because I've been treated so poorly by traditional western medicine - and most of one side of my family is in the healthcare field (physician, supervising RN, pharmacist, psychiatrist). Even my cousin now avoids western medicine except in absolute emergencies and most of the others want to leave the healthcare field.
You're just not well-informed. Rapid weight loss can reset the metabolism to a much lower rate, leading to people eating modest meals and continuing to gain weight following the original weight loss. This is why many people who've had bariatric surgery or gone on crash diets do lose the weight, but end up gaining more afterward. This article is just ill-informed and mean.
