The number of calories a person needs depends on their age, gender, and level of daily activity.

A poor diet and malnutrition can occur regardless of calories. A meal plan should be balanced in terms of nutrients, too. A poor diet can lead not only to malnutrition, but also a low mood and loss of motivation. This can cause to dieters drop out before reaching their target weight.
When dieters have reached their target body weight, they should gradually increase their daily intake until they reach their “weight maintenance” figure.

Crash diets may have positive short-term results, but they tend to have poor long-term success rates.
If you manage to sleep between 7 and 8 hours continuously in each 24 hour period, your body weight control will be more successful. Sleep deprivation or lack of sleep can make you put on weight.
In 2009, researchers combined the successful weight loss strategies of 6,000 individuals.
They came up with the following measures to prevent putting weight back on after losing it:
Physical activity: Do at least 200 minutes each week of moderate-intensity exercise. This should be spread out over at least three days (do not do all the minutes in one go each week).
Watching TV: Limit your TV watching to no more than 10 hours each week. Many people might find this recommendation particularly difficult to follow.
Fat limit on diet: Make sure that no more than 30% of your nutritional intake is in the form of fat.
Eat consistently: Resist the urge to overeat during weekends and holidays. Your food intake should follow a regular routine. Overeating not only upsets your routine, it most likely impacts on your metabolism.
Breakfast: Never miss it. Breakfast helps stave off hunger later on in the day, and this can help prevent overeating and snacking.
Monitor yourself: Keep a close check on what you eat and regularly weigh yourself.
Weight and health
Some health professionals and researchers disagree with focusing on weight loss when advising patients and clients. They believe that dieting and weight-loss efforts may lead to further weight gain and poorer health.
Instead, they suggest focusing on better health statusTrusted Source, because this results in better body weight control over the long term.
Linda Bacon, of the University of California, Davis Department of Nutrition, said:
“Although health professionals may mean well when they suggest that people lose weight, our analysis indicates that researchers have long interpreted research data through a biased lens.
When the data are reconsidered without the common assumption that fat is harmful, it is overwhelmingly apparent that fat has been highly exaggerated as a risk for disease or decreased longevity.”
A number of supplements are available that claim to help people lose weight.
They recommend finding a qualified and experienced instructor to guide you through these activities.
Bariatric surgery is performed in circumstances where other weight loss methods are not effective.
Bariatric surgery, also known as weight loss surgery, is a surgical procedure which is carried out on people whose body mass index is high enough that it puts them at risk of serious complications.
It is only recommended if other weight-loss strategies have not worked.
The procedure involves either reducing the size of the stomach with a gastric band, or surgically removing part of the stomach.
In some cases, gastric bypass surgery is recommended, in which the small intestines are rerouted to a small stomach pouch.
After the procedure, the person’s appetite is considerably reduced, and they cannot absorb or digest food as fully as before.
Bariatric surgery can be an effective way of reducing body mass index (BMI)Trusted Source for people with severe obesity, although research results for different procedures have not confirmed which type of surgery is best in each case.
The procedure has proven successfulTrusted Source in to treating type 2 diabetes and reducing cardiometabolic risk.

When is weight loss bad?
In some cases, losing weight may not be the answer.
Weight loss happens when a person exerts more energy than they consume. This is called a negative energy balance. The body seeks out stores of energy, starting with fat, to make up the shortfall.
In a person with little fat, more muscle and lean tissue will be used up. This can lead to further health problems.
a higher risk of osteoporosis
reduced muscle mass and strength
problems regulating body temperature
a lower ability to resist infections
A severe loss of body mass can be life-threatening.

Obesity: how much is in the genes?
A number of genetic factors may influence how people gain weight, according to research published in the journal Obesity.
