Researchers have observed weight regain following weight loss across a range of populations and types of weight-loss diets.

When we are hungry, the hormone ghrelin stimulates the brain. Our brains pay more attention to cues for unhealthy foods—those which are high in sugar and fat—than healthy foods when we are hungry.&...
Dieting often involves “giving up” more pleasurable foods in an attempt to reduce calorie intake. But if we are asked to avoid eating the food we enjoy, researchers have found that we will crave it.
The behavioral and cognitive response to deprivation may inadvertently be creating more temptation.
A problem with dieting rules is that only a small violation—a sneaky slice of cake, for example—is enough to derail the whole diet. Researchers call this the “what-the-hell effect”.
Diets that require the dieter to follow rigid rules or forbid them from consuming foods they enjoy appear to be problematic, as they paradoxically increase the risk of overeating.
Dieting can pretty fast become an obsession, as shown by today's individuals who, influenced by everything that the media is promoting, want, at all costs, to be fit and slim.
When dieting, not only does the individual lose weight, but he or she is at risk of losing also a large amount of money. The diet industry generates high income every year, taking advantage of people's obsession to look fit.
However, it often happens that these diets who are supposed to work wonders end up by making people lose only money and no kilos whatsoever.
As shocking as it may seem, diets are not the key to a forever slim body.
Research has shown that most of the people, who have dieted at some point in their life, end up by regaining the initial weight or even more than they had when they started the diet.
We're all different. If we are all on the same weight-loss diet, there will be various outcomes. Some people will lose a lot, some will lose a little, and a few will even gain weight.
Scientists are continually finding links between genetics and nutrition. Many of us have a gene called FTO that makes us more likely to be overweight. You can get a genetic test to tell which variant of the FTO gene you happen to have.
However, scientists who study the genetics of nutrition think it’s premature to base nutritional advice on your DNA. That FTO gene, for example, has only been shown to make a few pounds’ difference in body weight.
The coded messages of your DNA are billions of letters (nucleotides) long. Personalized nutrition companies only care about a few of your DNA letters and can tell you which "variant" you have at each of those locations (known as SNPs) along your DNA strands.
Genetic testing companies can learn what SNP variants you have by supplying them with a vial of spit.
