Some popular beliefs attached to weight loss have been shown to either have less effect on weight loss as commonly believed or are actively unhealthy. According to Harvard Health, the idea of metabolism being the "key to weight" is "part truth and part myth" as while metabolism does affect weight loss, external forces such as diet and exercise have an equal effect. They also commented that the idea of changing one's rate of metabolism is under debate. Diet plans in fitness magazines are also often believed to be effective, but may actually be harmful by limiting the daily intake of important calories and nutrients which can be detrimental depending on the person and are even capable of driving individuals away from weight loss.
i am 39 years old and have a good 35 lbs to lose. like you i ate whatever i wanted as a teen and stayed very thin (and i did literally no exercise) but then i hit 21 or so and realized i needed to cut back on calories and jog as weight slowly came on. then at 28-30 i got back to my teenage weight of 114 by jogging and watching carbs, i got married at 34 and since then pounds have just crept on for both my hubby and myself… i have tried everything :/
Over the past few years it has become clear that weight is an important health issue. Some people who need to lose weight for their health don't recognize it, while others who don't need to lose weight want to get thinner for cosmetic reasons. We understand that in some ways your weight is different from, for example, your cholesterol level or your blood pressure, because you can't see what these are by looking at someone. Many patients have had health care providers who approached their weight in a less-than-sensitive or helpful manner. Some patients may have had health care encounters in which they felt blamed, but not helped. Successful weight management is a long-term challenge.
