Why Mom was Right About the Science of Diets


Dieting is the practice of eating foods prescribed and monitored to reduce, maintain or increase body weight. In other words, it is a conscious control or restricted diet.


Restricted diet is often used by those who are obese or overweight, usually in combination with some type of physical exercise to lose weight. Some people diet to gain weight (usually in the form of muscle). The diet can also be used to maintain a stable body weight.



Low carbohydrate

Protein Power and Atkins diets boost low amounts of tend to be relatively higher in protein and fat content. Such low carbohydrate diets are often ketogenic (restrict carbohydrate intake sufficiently to cause ketosis-an increase in the level of ketone bodies in the body).


Low in calories

Diets that are low in calorific value usually produce energy deficits of around 500-1000 calories per day, which could amount to almost 0.5 kg (1.1 lb) for 1 kilogram (2.2 1b) of weight loss per week. Some diet plans like low calorie DASH diet and Weight Watchers are included.


National Institutes of Health (NIH) looked at 34 randomized controlled trials in an effort to determine the efficacy of such low-calorie diets through testing. The NIH found that such low-carb, high-protein, high fat diets were able to lower total body mass by 8% in the short term, over a period of about 3-12 months. Women on low-calorie diets should be at least 1200 calories a day. Men must have a minimum of 1,800 calories a day.


Very low in calorie diets

Very low calorie diets provide 200-800 calories a day to maintain protein intake but limiting calories from fat and carbohydrates. The body subjected to starvation and produce an average loss of 1.5 to 2.5 kg (3.3 pounds to 5.5) per week. “2-4-6-8”, a popular variety of modes, after four days of the cycle in which only 200 calories consumed on the first day and the second day 400, 600 on the third day, the fourth day 800 then completely empty stomach, and then the cycle are repeated.


Such diets may not be recommended for general use, as they are associated with highly adverse effects such as increase in the risk of gout, loss of muscle mass, and electrolyte imbalances side effects, which could be fatal. People who try these diets should be closely monitored by a doctor to avoid risk of any dire complications.

Atkins diet

The Atkins diet is not a new phenomenon. The diet first made entrance around the late 1970s and has grown in popularity in the last few decades in response to the low-fat diet craze amid higher rates of diabetes plaguing our society.

Hoodia diet

Hoodia diet is the latest most effective diet to come out today. With so many diet trends it natural for anyone to question this new diet regimen. The diet has been mentioned in several TV shows such as The Today Show, 60 minutes, BBC, and Oprah. Like the other diet plans before, will it become just another trend to be swept off under the carpet and followed by those who can afford it?

How different is it compared to others that have come before it and many more that are continually sold in the internet? We will find out when we turn our lenses to focus on this diet regimen. Stay tuned!


Religious diet requirements

Religious requirement may be a factor in motivating people to adopt certain restrictive dieting. For example, the Bible book of Daniel (1: 2-20 and 10: 2-3) refers to the escape of 10 or 21 days of food (Daniel Fast) declared unclean by God in the Law of Moses.


In modern versions Daniel Fast, food choices may be limited to whole grains, fruits, vegetables, legumes, nuts, seeds and oil. Daniel Fast compares vegetarian diet that excludes animal products. Passes strongly suggest that Daniel fast promotes good health and mental performance.


Fasting is practiced in different religions. Examples include Lent in Christianity; Yom Kippur, Tisha B’Av, Esther fasting, Gedaliah seventeenth of Tammuz and the tenth of Tevet in Judaism. Muslims refrain from eating during the day for a month, Ramadan every year.


Vegan/vegetarian diet

Raw food diet


Eating raw foods is a boost to your metabolism according to research. According to the proponents of raw food diet, it takes a little more energy to digest raw foods, which is considered a healthy process.


Instead of spending energy to rid itself of toxins produced by cooking food, the body would rather use its energy to feed each cell in its being, sending vitamins, fluids, enzymes and oxygen to make your body the efficient machine it was intended to be.



Everyone wants to know how to lose weight quickly. We know the usual answer how many do this- To control my diet and exercise frequently. But if it was that simple, then there would be so many fat people in this world!


With all the lies and hype surrounding the weight loss industry it can be difficult to separate the hype and lies from the truth.


Being healthy is not just weight. Healthy weight reflects a healthy diet and regular physical activity.
