While dieters usually cut down on calories, 300 every day is not enough for anyone. It is better to determine what your daily calorie needs are based on your body composition, activity level, and overall goals. Discuss this with your doctor before doing any diet.
#4: Alkaline diet
The alkaline diet is not as dangerous as other fad diets, however, there are many claims that are simply not supported by science. The basic idea of the alkaline diet is to, well, be basic. For something to be basic or alkaline, it must have a pH level of more than 7.
Usually, our blood stays within the pH levels of 7.35 to 7.45. Any deviations higher or lower than this can negatively affect the body. The alkaline diet aims to consume food and drinks that have higher pH to prevent acidification of the blood and body.
While studies have shown that cancer cells can create an acidic environment and that stomach acid can cause ulcers, this does not mean consuming alkaline food can cure or prevent these conditions. Our bodies already have several buffer systems that work to maintain the optimal blood pH. Overly acidic and alkaline substances can equally harm the body.
#5: Cracker diet
Rice is a staple food in many countries, especially the Philippines. Cutting down on white rice and refined sugar is encouraged by health experts in order to lose weight and prevent diseases like diabetes.
However, many Filipinos tend to replace rice with another starch which may not be healthier. For instance, one of the oldest fad diets is to only eat saltine crackers or biscuits, a boiled egg, and water.
What makes the cracker diet a dangerous fad diet is that it is nutritionally unbalanced. In addition, one pack of biscuits generally contains the same amount of calories, carbs, and protein as a half-cup serving of white rice. Meanwhile, pre-packaged crackers contain more fat, sodium, and less vitamins and minerals than the same serving of rice.
