Are there any 2 week weight loss diets that work?

There are 2 weeks weight loss diets that work, that’s for sure. The difficult part is to choose a diet that works for you and generate the results you want. In this article we can help you understand more about 2 week weight loss diets and be able to differentiate which of them work and which are fads.

There are various reasons why people want to lose weight. Some people lose weight because of health reasons, others because of their job (models and celebrities), and some because they need to prepare for a big event like weddings or office parties, or maybe because they want to raise their self-esteem and improve their body image.

Whatever the reason is, people are always looking for the fastest way to lose weight. Because of this, some people would resort to weight loss pills, diet plans, or even surgery. Although some of these weight loss methods do work; we should still consider the large percentage of those that don’t. Some of these “quick fix” techniques could even possibly do more harm than good, thus it is very important to consult your doctor before trying any of these.

The most popular “quick fix” method is a weight loss diet. There are countless diet programs available in the Internet alone. If you try to key in “fast weight loss diet plan” in the Google search bar, it would generate a lot of diet plans or menus that promise fast results. Some claim in losing 10 pounds in 10 days, some say 2 weeks, and others say 7 days. A lot of these diets are promising and aside from the challenge of choosing the right diet for you, the biggest question is: Are there any 2 week weight loss diets that work?

The direct answer is YES, there are actually a lot of two week diets that work. However, the success of the said diet depends on the actual amount of weight loss in a period of 14 days. To better understand this, it is essential to know a bit more on how the body loses and gains weight. If you understand this it will be easier for you to also understand how to lose weight in 2 weeks.

The first fact that you should remember is the ratio between calories and pounds. There are 3500 calories in every pound. This simply means, that for every 3500 excess calories that you get rid of by eating less caloric food or by burning it through exercise, you would lose one pound. On the other hand, if you gain 3500 excess calories, you are also adding a pound to your weight. This numbers mean that, if you lose 3500 calories in 2 weeks; you lose one pound. If it’s 7000 calories in two weeks; you lose 2 pounds in two weeks and so on.

Each person has a different daily calorie requirement. Factors that affect the calorie requirement are age, sex, weight, height, and intensity of activities in a day. You may use online calorie calculators or the Harris-Benedict equation to compute your daily calorie needs. However, an average adult has 1500-2500 caloric requirements every single day. Which means, losing 3500 calories in a day to meet the promise of losing 10 pounds in 10 days is not only dangerous but it is a bit impossible. If you do your math, you would also be able to figure out if the amount of weight loss promised by any diet is realistic and safe.

The healthiest weight loss for two weeks is 2-4 pounds. Sorry to disappoint you with these low numbers, but if you want to lose weight safely and you’re thinking of a long term goal, this is the safest I can recommend. You would see the candidates for the Biggest Loser lose more than these numbers in two weeks, but do remember that these people are closely monitored by health professionals and nutritionists.

If that would be the case, you need to lose 500-1000 calories everyday. You do this by eating foods that contain fewer calories like fresh fruits and vegetables coupled by burning the excess fat by exercising.

I always advice my clients to eat a balanced diet everyday; that means, you should eat foods from different food groups that have fewer calories. I highly discourage my clients to go on with no-carbohydrate diet because it will only result to ketosis which could increase the body’s toxic level and damage the organs. And most importantly, I always remind my clients to never try starvation diets. Fasting is okay for religious purposes, however starving yourself will only result to anorexia, malnutrition, and more serious health problems.

So, the next time you are offered a diet plan that guarantees results within two weeks or any specific time, try to check first if it’s realistic and safe. This way, you will not only save yourself from wasting the extra dollars but you save yourself from the disappointment as well.

  • I agree that healthiest weight loss for 2 weeks is 2-4 pounds.
    Overweight people should not believe the advertising of crash diets, drugs, or any “miracle cures” that promise quick weight loss. Temporary diets produce temporary results.Excess pounds gained on the body have been gained slowly through poor eating habits and lack of exercise. Likewise,permanent weight loss is also a slow process consisting of regular exercise and proper nutrition.
