Maintain, Don’t Gain
- Maintaining a healthy weight is important for health. In addition to lowering the risk of heart disease, stroke, diabetes, and high blood pressure, it can also lower the risk of many different cancers.
- Move more, eat less. Turning off the television and skipping the sugary drinks are two ways to get started.
Your weight, your waist size, and the amount of weight gained since your mid-20s can have serious health implications. These factors can strongly influence your chances of developing the following diseases and conditions:
- Cardiovascular disease, heart attack, stroke
- Sleep apnea
If your weight is in the healthy range and isn’t more than 10 pounds over what you weighed when you turned 21, focus on maintaining that weight by watching what you eat and exercising.
Because most adults between the ages of 18 and 49 gain 1-2 pounds each year (1), stopping and preventing weight gain should be a priority. Gaining weight as you age increases the chances of developing one or more chronic diseases.
- In the Nurses’ Health Study and the Health Professionals Follow-up Study, middle-aged women and men who gained 11 to 22 pounds after age 20 were up to three times more likely to develop heart disease, high blood pressure, type 2 diabetes, and gallstones than those who gained five pounds or fewer.
- Those who gained more than 22 pounds had an even larger risk of developing these diseases. (2-6)
- Another analysis of Nurses’ Health Study data found that adult weight gain—even after menopause—can increase the risk of postmenopausal breast cancer. (7)
- Encouragingly, for women who had never used hormone replacement therapy, losing weight after menopause—and keeping it off—cut their risk of post-menopausal breast cancer in half.
Does Being Overweight Reduce Mortality?
You may have seen news coverage of a study claiming that being overweight and obese may reduce mortality (8, 9) but a panel of experts discussed why the general public should not rely on these flawed study findings.
- The main flaw of this study is that the normal weight group, which showed an increased mortality risk compared to the overweight group, included more heavy smokers, patients with cancer or other diseases that cause weight loss, and elderly people suffering from frailty. There was no distinction made between these unhealthy normal weight people and lean healthy individuals. The overweight and obese groups did appear to have a lower mortality rate than this mix of healthy and very unhealthy normal weighted individuals, and this flaw led to false conclusions that overweight and grade 1 obesity carry no risk and may offer reduced mortality.

What Causes Weight Gain?
1. Diet: The quantity and quality of food in your diet has a strong impact on weight.
2. Genes: Some people are genetically predisposed to gain weight more easily than others or to store fat around the midsection.
Genes do not have to become destiny, however, and studies suggest that eating a healthy diet, staying active, and avoiding unhealthy habits like drinking soda can prevent the genetic predisposition to risk for obesity. (10)

3.Physical inactivity: Exercising has a host of health benefits, including reducing the chances of developing heart disease, some types of cancer, and other chronic diseases. (11) Physical activity is a key element of weight control and health.
4.Sleep: Research suggests that there’s a link between how much people sleep and how much they weigh. In general, children and adults who get too little sleep tend to weigh more than those who get enough sleep. (12, 13)
- For example, in the Nurses’ Health Study, researchers followed roughly 60,000 women for 16 years. At the start of the study, all of the women were healthy, and none were obese; 16 years later, women who slept 5 hours or less per night had a 15 percent higher risk of becoming obese, compared to women who slept 7 hours per night. Short sleepers also had 30 percent higher risk of gaining 30 pounds over the course of the study, compared to women who got 7 hours of sleep per night.
There are several possible ways that sleep deprivation could increase the chances of becoming obese.
- Sleep-deprived people may be too tired to exercise, decreasing the “calories burned” side of the weight-change equation.
- People who don’t get enough sleep may take in more calories than those who do, simply because they are awake longer and have more opportunities to eat.
- Lack of sleep also disrupts the balance of key hormones that control appetite, so sleep-deprived people may be hungrier than those who get enough rest each night.

Eating a healthful diet and maintaining a healthy body weight is important. Diet and body weight are related to health status. Most americans need to improve some part of their diet.

A calorie is a calorie regardless of its source. Whether you're eating carbohydrates, fats, sugars, or proteins, all of them contain calories. ("Balancing Calories"). If you take in more calories than you use up it gets stored as fat. If you want to stay the same weight you have to eat the amount of calories that you use every day. If you want to lose weight you have to take in less calories and if you want to gain weight you have to take in more calories. If you stay the same weight it is called caloric balance.
If you need to lose weight keep it takes about 3,500 calories below your calorie needs to lose a pound of body fat. This will help you lose about one to two pounds a week you will need to cut down calories taken by 500—1000 calories a day ( "Balancing Calories"). To start a program you need to write everything down that you eat and add it up every day. This will help you see how many calories you're eating every day. Each person is different and you have to find out the balance that works for you. A healthy lifestyle requires balance in the foods you eat, in the drinks you drink in your daily activities, and in the amount of physical activity or exercise you include in your daily routine. ( "Exercise vs. Diet for Weight Loss").
