Question: Why am I getting fat if I’m on a diet?
There are many reasons why we put on weight despite being on a diet. Generally they have to do with mistakes we make throughout the day, which we consider harmless, as explained in this article, but eventually translate into more calories are transformed into fat. The result is extra kilos.
The imbalance between caloric intake (food intake) and energy expenditure (exercise) -current or past- the body is the main reason why we put on weight. This gain need not result in immediate excess weight. In fact, most obese people have gained weight slowly, over many years.
Still, there are other reasons that costs us more control and that may be behind weight gain. In women, these factors have to do with hormonal changes that often occur in life stages such as menopause.
Finally, stress, anxiety or depression are also causes that can make us fat, as you can read in this article.
Here we show you the most common factors that may be behind weight gain. But I recommend that you go to a doctor if you are doing a controlled by a nutritionist and still not get slimming diet.
Genetic susceptibility: One of the causes that can lead to obesity is genetic susceptibility, ie, have a predisposition. Recent research has found that some people with a particular variant of the FTO gene increase by up to 70 percent predisposition to obesity. A study published in the medical journal The Journal of Clinical Investigation, indicated that this alteration causes an increase in levels of the hunger hormone, ghrelin, and makes high-fat foods more palatable.
Rebound effect: Having made a calorie restriction diet without medical supervision many people experience weight gain known as yo-yo effect or rebound. It was thought that only happened if they had followed some quick diet of so-called ‘miracle’. However, recent studies have indicated that can occur even if there has been a medical examination and that the perpetrators are two hormones, leptin and ghrelin.
The study, conducted by the Biomedical Research Center in Red-Pathophysiology of Obesity and Nutrition (CIBERobn), observed that could previously determined whether a plan regime would be successful or not and whether patients quickly recover weight lost after the diet.
Leptin (produced in adipose tissue) is involved in satiety and tells the body when to stop eating, while ghrelin (a protein synthesized in the duodenum and stomach) awakens the appetite sensation. Patients undergoing study followed a low calorie diet for eight weeks. After six months, the same patients were recruited and divided again in reclaimers weight and reclaimers. A blood test was performed and observed all those who had gained weight again showed r atios twice higher at baseline than those who did not suffered.
Diseases or metabolic causes: Some diseases such as cardiovascular or kidney may produce an increase in fluid retention that may exist with weight gain even if you are dieting.
On the other hand, other hormonal disorders such as polycystic ovary syndrome or hypothyroidism may be responsible for this increase. The annual gynecological examination with ultrasound can determine if there Polycystic ovary. The problems in the thyroid gland is diagnosed by a blood test.
The, common among women of childbearing age, premenstrual syndrome can also cause a slight increase in weight. This is due to fluid retention and comes in addition to breast tenderness, heavy legs or other symptoms such as headaches or irritability accompanied. Usually it increased between 1.5kg (3.3lb) 3kg (6lb) depending on the amount of estrogen and progesterone. For example, if there is excess estrogen due to stress or nervousness and a smaller amount of progesterone by the same causes weight gain may be higher.
Menopause: Some people say that during this stage of life is not fattening, but are women and caloric intake or fatty foods responsible for the weight gain. It is not true. During menopause it does exist kilos gain as many physiological changes in the body of a woman. Furthermore, they have more tendency to accumulate abdominal fat thereby increasing vascular risk.
During menopause weight loss it is more difficult and the decline in female hormones causes increase appetite, you eat more and fattening even being on a diet and energy expenditure is also lower.
According to research conducted by experts from the University of Pittsburgh, USA, and published in the Journal of the Academy of Nutrition and Dietetics, to combat obesity from 50 not enough traditional methods but you have to make changes eating habits.
For example, should increase consumption of fruits and vegetables, meat change and cheese fish, take more grains and not consume fried. Also, exercise should be regular and daily (is considered optimal activity 45 minutes brisk walk. Still, swimming is an excellent exercise because it produces no injury to articular level).
On the other hand, some women experience anxiety states, irritability and depression that can give way to greater food intake, more sedentary lifestyle or medications such as antidepressants that may be responsible for this increase. Hormone replacement therapy also favors excess weight.
Pregnancy Weight gain during pregnancy is necessary and inevitable. As explained in the article The pregnancy diet, those responsible are women uterine and organs. about 12.5 kilograms total increase due to: the growth of the baby, breast augmentation, the palacenta, amniotic fluid, maternal liquids, or fat stores. This deposited in the abdomen, back, thighs and arms, is due to an altered metabolism of carbohydrates. But it should disappear in infancy.
The reason a greater weight gain during pregnancy is that some women confuse eat for two for eating for two and exceed quantities to meet the nutritional needs of pregnancy. And increased weight more than normal can endanger the health of the baby and mother occurs.
Depression: Like people with stress, individuals suffering from depression, a disease that is more common in women, are more likely to adopt habits of unhealthy life, increase food intake and not perform any physical activity to help consumption offset with spending, basic standard to achieve optimal body weight and curb obesity.
In addition, some studies have indicated that there is a genetic link between depression and obesity. A study published in the journal Molecular Psychiatry noted that patients with recurrent depression there was a relationship between the FTO gene and BMI (Body Mass Index). Specifically, researchers at the University of Granada found that patients with depression had a higher BMI and attributed to this gene.
