Diets don't work: Why What are the reasons for this

Diets don't work :When dieting why not work

Diets Don't Work

At any given time, more than a third of Americans follow a specific diet, with weight loss as the main reason. Most of them will be disappointed because even upon success, lost weight is frequently regained within a few months.

While most weight-loss diets don can help you lose weight, they may not be work in the long term for a number of reasons. Some people do not follow their diets carefully and do not lose much weight even from the start. Others may forgo the diet completely after a while because it is too restrictive or unattractive foods. Some may engage in less physical activity because they consume fewer calories. But who hasn't heard of someone doing everything right and still losing a minimal amount of weight, or regaining lost weight over time? Maybe this person is you.

Even when research studies confine study subjects to a research setting — with carefully-controlled calories, food types, and physical activity, and with intensive counselling, teaching, and monitoring — the lost weight and other health benefits (such as improved cholesterol and reduced blood pressure) tend to disappear soon after the study ends.

You cannot choose the right diet if none of it works

According to a new study, common diets simply don't work for the vast majority of people. Or more accurately, it is modestly effective for a while, but after a year or so, the benefits are largely gone.

In a large systematic review and meta-analysis, recently published in the medical journal The BMJ, researchers analyzed 121 trials involving nearly 22,000 overweight or obese adults who followed one of 14 popular diets, including the Atkins Diet and Weight Watchers. Jenny Craig, the DASH diet and the Mediterranean diet for an average of six months. The diets were grouped into one of three categories: low-carb, low-fat, and moderate macronutrient (the diets in this group were similar to those in the low-fat group, but had slightly more fat and slightly less carbohydrates). Excess weight loss and cardiovascular measures (including cholesterol and blood pressure) while following one of these diets was compared with other diets or regular diets (a system in which a person continues to eat as they normally do).

While measures of weight, blood pressure, and cholesterol generally improved at the six-month mark, results at the 12-month mark were disappointing, to say the least.

  • While both the low-carb diets and the low-fat diets resulted in a weight loss of about 10 pounds in six months, most of the weight lost was regained within one year. People in the moderate macronutrient group tend to lose less weight than those who follow other diets.
  • My blood pressure and cholesterol results improved slightly in six months but were generally back to where they started a year later. One exception was noted: levels of LDL ("bad") cholesterol decreased while the Mediterranean diet lasted for one year.
  • There were no significant differences in other health benefits between the different diet programs

All is not lost

Based on this new report, you may be tempted to ditch your hands and ditch the weight loss diets don altogether. But there's another way to look at this: It probably doesn't matter which plan you choose (be it low-carb, low-fat, or anything in between) more than it does if you stick to it.

The average duration of the studies included in this analysis was six months. What if they last for 12 months, two years, or for life? The benefit would have been greater and longer-lasting. The trick is to choose a diet that includes foods that you already love so that it is not difficult to stick to them.

Additionally, there are factors other than diet that can have a significant impact on weight. For example, daily physical activity, regular exercise, and sleep are important to help maintain a healthy weight.
can you lose weight on a bad diet?
Instead of following a very restrictive or crash diets, I endorse the Mediterranean Diet. It is among the best-studied regimens, performs well when compared to other diets (as in this analysis), and was the only diet in this analysis that had long-term effects on LDL cholesterol levels.

The bottom line

Losing weight is not easy. If you are struggling with weight, talk to your doctor, a nutritionist, and possibly a health coach. They review this study with them, and together decide on the diet and other lifestyle changes that appeal to you. Then stick with them. Remember, you’re most likely to stick with lifestyle changes you actually like.
