So, what is a calorie anyway? More significantly, did you know that to which we refer to as a calorie is really a kilogram calorie? No matter how you refer to it here is the more important thing to know about it. It's the amount of heat energy required to raise one kilogram of water 1 degree Celsius. You'll soon know what this has to do with food in a moment.
Energy is in reality heat output. Whenever muscles contract to start movement, your body is constantly using energy, creating heat so calories are always being burned. You burn energy just by breathing. If you check your body temperature this instant, unless you're not feeling too well, your temperature should read 98.6 degrees. You radiate heat constantly, and since a calorie is a measure of heat yield, which we can also use to define how many calories a food item has.

When the number of kilogram calories that you take in equals the number of kilogram calories that you expend in energy, then you are upholding an energy balance and your weight will not fluctuate very much. Established diet wisdom (a contradiction in terms) says that if you cut back on kilo-calories, you will be at an energy deficit, therefore you should lose weight. Unluckily, if long term weight loss is the target, it's not quite that easy. The best way for me to describe the snare that happens to dieters is to provide you with a true example of a diet experience. I'll use a woman in this example, but it can be a man as well.
The Weight Loss Victim Who Knew Too Little - After seeing this ad: "Lose 30 pounds in 30 days. Lose Weight, Lose Inches. Isn't it time?," a woman enters her nearby weight loss center. Uneasily she walks through the door. Within moments, she's greeted by a professional Dietitian. At a furnished conference area they sit and talk about food. After the interview, the Dietitian says, "your caloric intake is 2300 calories per day. We should limit you to 1200, and we'll give you (which really means "sell you," right?) these bundles of food and delicious shakes... and then you should notice some dramatic weight loss!"
A week later the woman goes back to the diet center after following the program and the First thing they do is get her on a scale. She's thrilled! She lost five pounds! In just a few short days! She buys more packaged food and After a week she's lost another two or three pounds! Then week 5 comes around and things change for the worse. This time when she gets on the scale... She didn't loss any weight! No weight loss from last week to this! She starts to panic, but the Dietitian is clever. "You've just hit the plateau" he says. We'll just cut you back to 900 kilo-calories. It just means smaller parcels of food and smaller shakes.
Sure enough, the woman commences to be skinny again. The only problem is, this time the weight loss is followed by this little voice inside her head that says things... like... french fries. Ice cream. She's getting cravings and she commences to question her own will power. After a few days of fighting against those little voices, she gets back on the scale and realizes she has hit the second plateau. She eventually just gives up. She gives in to temptation and although she intends to just "have a taste," her craving consumes her and she falls off the wagon hard. She eats everything that she depreived herself of and as a result, she gains more weight back than she lost to begin with. That's not the worst of it. The truly sad thing is she blames herself as the reason. That's not true though.
The Accuracy Regarding Kilogram Calorie Depletion - Her problem wasn't will power but rather chemical brain messengers called neurotransmitters telling the body it needed to eat to survive. Food! Her body, in its attempts to save her from starvation, does not understand that she's dieting to lose weight. It is trying to save her life, therefore, those innate protective mechanisms force her the nutrient she can survive off of the longest... namely fat... and that substance that will provide the fastest energy source... sugar. Once she succumbs to the hunger, her blood sugar skyrockets, her pancreas starts kicking out massive measures of insulin, and her body goes into a binge state. This binge is a direct result from the loss of calorie intake or what the brain perceives as STARVATION!
There's something else the Dietitian didn't tell her. Her weight loss was a result of three factors. Water weight loss, some fat loss, but also (and probably a more frightening consideration) she was losing muscle. Water comprises over 70% of your body weight. If you're going to lose water weight only that's likely as effective as just cutting off a part of your body. Sure you'll be lighter for it, but I don't think you'll be any happier. Same idea. The second part is what we're trying to get rid of but, Unluckily, in the process you tend to lose muscle tissue too.
The diet is leading to her body cannibalizing her own muscle tissue. Muscle is metabolically active tissue. Fat is not. That means muscle burns kilo-calories and fat doesn't. When you give up muscle, Your metabolism slows! Muscle is also the site on your body where fat is burned. By starving your body you reverse the roles somewhat because now your body no longer wants to burn fat (it doesn't want to burn anything). The end result of a program based upon kilo-calorie deprivation is a slower metabolic process, a non-supportive shift in hormonally brought on appetite, a decrease in fat burning capacity, and an inevitable collection of fat. When you embark upon a diet, you are in turn programming your body to store fat in the future.
Conclusion - So, why have you lost weight on many diets, and then gained it back? Quite frankly, because that's what diets do! How can you tell the difference between a good diet and a bad one? For one thing, if it incorporates the word diet, which indicates deprivation, its a bad diet. A good nutrition program is one that stirs the metabolism, offers all of the foods needed for endurance, energy, tissue regeneration, and wellness. It should also stress more on what you should eat rather than what you shouldn't.
