In nutrition, diet is the sum of food consumed by a person or other organism. The word diet often implies the use of specific intake of nutrition for health or weight-management reasons (with the two often being related). Although humans are omnivores, each culture and each person holds some food preferences or some food taboos. This may be due to personal tastes or ethical reasons. Individual dietary choices may be more or less healthy.
A new German study found that when you drink 17 ounces of water (about two glasses) within a certain time frame, your metabolic rate shoots up by about 30 percent. Using these results, they estimate that by increasing your current water intake by 1.5 liters a day, a person would burn an extra 17,400 calories a year, resulting in about a five-pound weight loss.
To stay fit and maintain your shape a regular workout helps a lot. But when it comes to losing weight and getting back in shape, a regular workout or exercise routine won’t suffice. You will have to take it a step further and take care of your diet in order to lose weight. Even the gym instructors would tell you so. Exercise and diet are the two sides of a coin. You can’t achieve weight loss with just one of them. A regular exercise routine and a healthy diet is your route to salvation.
Weight loss, in the context of medicine, health, or physical fitness, refers to a reduction of the total body mass, due to a mean loss of fluid, body fat or adipose tissue or lean mass, namely bone mineral deposits, muscle, tendon, and other connective tissue. Weight loss can either occur unintentionally due to malnourishment or an underlying disease or arise from a conscious effort to improve an actual or perceived overweight or obese state. "Unexplained" weight loss that is not caused by reduction in calorific intake or exercise is called cachexia and may be a symptom of a serious medical condition. Intentional weight loss is commonly referred to as slimming.
I have been following the slow-carb diet for nearly 3 weeks with no significant weight loss. I will admit I have made a few tweaks to fit my lifestyle. I go to the gym at 5:30am and do not have time or the desire to eat a big breakfast before going. So I normally make a whey protien shake with water and about 1/4 cup frozen berries (I know fruit is a no-no) when I get home from the gym at 7. I then eat breakfast – eggs, black beans and spinach at 10. Lunch is either a salad with beans or slice of deli turkey or chili. I have not eaten any grains, sweets etc… I do use milk in my coffee instead of heavy cream. Why is heavy cream a better choice? I do have a glass of red wine at night and an occasional serving of sugar free gelatin. I take a spin class 2-3 days a week and run 20 miles per week as I am training for a Ragnar Relay.
Weight-loss programs often accentuate the difference. When sedentary men and women both start exercise programs, men tend to lose body fat, while many women don’t. In one study out of England, men and women were each put on commercial weight-loss programs such as Atkins, Slim-Fast and Weight Watchers. Two months in, the men had lost twice as much weight as the women -- and three times as much body fat. But by six months, the rate of weight loss had evened out between the genders.
It’s not as simple as calories in, calories out. Some calories adversely affect your hormones, your taste buds, and your health. Eating sugar and processed food, even in small amounts, leads to craving more food and feeling less energetic. You can eat more if you eat healthy, high-quality food that gives you energy and turns on the hormones that affect metabolism.
A good diet means optimal health, but not everyone has a positive relationship with food. Some people battle with their plate, piling on body image and obsessions, no less. A simple meal may be linked with emotions such as boredom, stress, and guilt. Such negative feelings make you react and reach for that slice of cake, setting you down a path of unhealthy behaviors. It’s easy to eat in the middle of the night, forego proper portion sizes, skip meals, to name a few untoward habits. These bad tendencies can lead to short-term dieting that rarely, if ever, works. A healthy relationship with food means a healthy lifestyle overall.

While you may or may not wish to weigh yourself frequently while losing weight, regular monitoring of your weight will be essential to help you maintain your lower weight. When keeping a record of your weight, a graph may be more informative than a list of your weights. When weighing yourself and keeping a weight graph or table, however, remember that one day's diet and exercise patterns won't have a measurable effect on your weight the next day. Today's weight is not a true measure of how well you followed your program yesterday, because your body's water weight will change from day to day, and water changes are often the result of things that have nothing to do with your weight-management efforts.
