People lose weight for many different reasons:
- Appearance - they want to look, fitter, more attractive or healthier, or simply feel more confident in their bodies.
- Overall health - they want to become healthier, live longer, and
avoid developing diseases associated with obesity and overweight.
- For a specific condition or illness - obese people with sleep apnea who lose weight have less severe symptoms - sometimes the sleep apnea goes away completely. Obese or overweight individuals with diabetes type
2 will usually have less severe symptoms if they can bring their weight down to healthy levels. One study found that overweight and obese males with diabetes type 2 who lost weight reported enhanced libidos.
- Fitness - to become fitter, to have more energy and stamina
- Sports competitions - a boxer, for example, may wish to lose weight so that he can remain within his weight category.
- Fertility - obese women who are finding it hard to get pregnant sometimes are more likely to do so if they lose weight.
Negative Energy Balance - in order to lose weight you need to be exerting more energy than you are consuming; this is called a negative energy balance. If you are in a state of negative energy balance, your body will seek out stores of energy, such as fat or muscle to make up for the shortfall - it will start using up your excess weight. In extreme cases, however, when the individual has little fat, more muscle
and lean tissue will be used up.
Sports - some sportsmen and sportswomen will try to lose weight even though doctors would say their body weight is ideal. In some cases, it might be to get better speeds or, as
mentioned above, to be within a weight classification for a competition.
Losing too much weight - If you become underweight, there are also certain health risks. Your chances of developing infections might increase, there is a risk of osteoporosis, reduced muscle mass and strength, and problems regulating your body temperature. There may even be a higher risk of death if your weight goes down a lot. There are thousands of different diet plans on the market that make amazing weight-loss claims. Some of them are well thought out, safe and effective, while others are not.

Some studies found that not only do people risk malnutrition if their diet is not well planned, but also loss of motivation. Most 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.
Can dieting alone lead to weight loss?
A 2017 study by researchers at Oregon Health & Science University showed that people who just reduce their daily calorie intake rarely lose much weight. The researchers explained that natural compensatory mechanisms in the body reduce a person's physical activity as soon as calorie consumption drops - in other words, the body slows right down if you eat much less. Dieting must be combined with exercise.
Study leader Judy Cameron said:
"In the midst of America's obesity epidemic, physicians frequently advise their patients to reduce the number of calories they are consuming on a daily basis. This research shows that simply dieting will not likely cause substantial weight loss. Instead, diet and exercise must be combined to achieve this
goal."In response to a reduction in calories, the human's natural body
mechanism goes into "conservation mode." Without exercise, there simply will not be much weight loss, they emphasized.
Can dieting alone lead to weight loss?
Controlling body weight.
Body Weight control is much more successful if you can combine a well-balanced diet with regular exercise. Crash diets may have positive short-term results but tend to have poor long-term success rates. If you manage to sleep between 7-8 hours continuously each 24 hour period, your body weight control will be more successful. Sleep deprivation or lack of sleep can make you put on weight.
A 2018 study published in the journal found that a consistent pattern of increased odds of being a short sleeper if you are obese, both in childhood and adulthood. According to the National Weight Control Registry (NWCR), after
combining successful weight loss strategies of 6,000 individuals, the following measures should be taken to make sure you do not put the weight back on:
- 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.
