Experts have opined that fad diet can be effective in reducing weight, at least in the short term. This is not a surprising conclusion considering that fad diet often consists of some form of calories restriction, and calories restriction does reduce weight, regardless of the proportion of macronutrients. The concern is whether this weight lost induced by fad dieting can be sustainable. There are also concerns that many fad diets have little consideration that a well-balanced, nutritious diet is critical for our bodies to function properly. Besides, there are really no good evidence to suggest that one fad diet is better than the other in inducing sustained weight loss. So think again before you embark on a certain fad diet. Not that they don’t work. But sometimes a well balanced diet, with some calories restriction and an active lifestyle with adequate exercise are all that it takes.
