What a relief! News that more people are quitting dieting, because it doesn't work for most of us. It's often just a cycle of losing and gaining the weight, which is NOT good for your longterm health. Actually the "yo-yo" effect is more damaging to health than being a healthy overweight person.
And YES, you can be overweight and still be healthy. Health professionals now think about "metabolic fitness", which means that your blood pressure, blood sugar, and blood lipids such as cholesterol are in normal range. This also refers to your cardiovascular fitness, including heart rate and ability to exert yourself.
Diets are often just not the answer.
