Many people find that they are putting on weight, and they have no idea why. But you should usually be able to establish the cause if you pay close attention to you habits. Here are some of the most common reasons:
1. Decrease in physical activity
You are in good health and you eat well, but you are still gaining weight. Weight gain for no reason can often be explained by a decrease in physical activity that is not being attended to.
This does not happen exclusively to athletes who have stopped practising. This can happen when you change your daily habits, such as if you change jobs or where you work; perhaps you used to walk and now you take the car or public transport.
Often it is a good idea to take up a sport or do some exercise at home if you suspect your diet is not the cause of your weight problems.
Many weight loss diets can actually be responsible for weight gain when undertaken irresponsibly. People have found that, after stopping a diet which has made them lose a lot of weight quickly, they gain back the weight very fast – sometimes putting on more weight than they ever lost.
3. Extra calories
Fizzy drinks with meals, a big glass of milk in the evening, sugar in your coffee which you drink times a day, grated cheese on all our meals, butter on bread…
You can be under the impression that your diet is healthy, but all these "extras" throughout the day can dramatically increase the total calories consumed.
Some women experience significant weight fluctuations during the hormonal cycle (and some do not) because of fluctuating levels of estrogen and progesterone.
Get out of a depression, fall in love, get married… Happiness can lead to unexplained weight gain, simply because we enjoy more life and therefore the pleasures of food!
6. Stress and fatigue
Stress and weight gain are frequently associated for several reasons including nibbling and storing fat.
Fatigue makes you gain weight especially when it is caused by a difficult sleep, but it also pushes you to feed yourself in too large quantities while it would be better to eat more dietary fiber.
Fatigue can be caused by hypothyroidism (lack of thyroid hormones) often associated with weight gain while eating more than usual.
A common theory of unexplained weight gain is depression. It is believed that depression can cause intense fatigue and a need to eat more than usual or consume a specific group of foods – usually fatty, oil and sugar food which increases the daily calorie intake.
Additionally, medications for depression sometimes have the side effect of weight gain, opening the appetite and slowing the basal metabolic rate. If you are concerned about this, talk to your doctor about changing your medication.
Note that many other medications can cause you to put on weight, including drugs for hypertension or diabetes.
8. Quitting smoking
It's not always easy to stop smoking without getting fat. Stopping smoking can lead to more or less weight gain. However, it shouldn't be a problem if you keep a healthy diet.
Potential weight gain for ex-smokers usually occurs at the very beginning of weaning. If you continue to gain weight after this initial period, the best solution is to exercise.
