Lose 15 Pounds In Two Weeks: Is It Safe?

No matter how alluring it may sound, it is not recommended to lose 15 pounds in two weeks. Evidence shows that a more gradual weight loss is more successful than a rapid one. Losing weight is not about going on a diet, quickly shedding pounds, and then getting back to your regular life. A successful and sustainable result comes from long-term lifestyle changes, including eating and exercise habits.

Experts recommend losing 1-2 pounds (0.45-1 kg) a week for your weight loss to be healthy and sustainable. Since 1 pound of fat equals 3500 calories, in order to reach your goal successfully, you need to consume 500-1000 calories less than your required daily calorie intake. This can be done with the help of a balanced diet that creates an adequate energy deficit with regular exercise (18).

But even though nutrition experts emphasize the efficiency of a slower pace of weight loss, some people still prefer the rapid results which usually require extreme calorie restriction. Such an approach to shedding pounds can be very harmful.

Lose 15 Pounds In Two Weeks: What Are The Risks?

One of the most important things in your life is your health. That is why you should always prioritize it, especially when it comes to losing weight. So, if you feel like you want to lose 15 pounds in two weeks despite what experts recommend, you need to look at the risks of such a rapid weight loss first. Here is what this slimming approach may cause:

  • Impaired Kidney Function

A 2015 study found that a rapid weight loss in males with normal weight is a risk factor for incident chronic kidney disease.

The participants of that study with a normal body mass index (BMI) who went through a rapid weight loss, experienced a decreasing estimated glomerular filtration rate (eGFR) change, whereas, in those who lost weight slowly, the eGFR change increased. 

The results imply that a slow weight loss pace is more beneficial for kidney function than rapid weight loss.

  • Worsen Fatty Liver Disease

Patients who suffer from fatty liver disease should be extremely careful when they choose a weight loss diet. It is recommended that to burn the fat in the liver, reduce the liver cell inflammation and injury, and potentially reverse some fibrosis damage, a person should lose from 5% to 10% of body weight. Experts suggest sticking to a recommended weight loss pace of 1-2 pounds a week. A rapid loss of weight may only add to inflammation and fibrosis (6).

  • Starvation

Following a very-low-calorie diet can mess with your levels of leptin, a hormone that takes part in the regulation of hunger and satiety. When you follow a regular diet, your leptin levels are normal, and it signals your brain that there is enough fat and that you are full. But when you limit your food intake intake dramatically, the unbalanced levels of leptin may result in an obsession with food, which could lead to increased hunger or even bingeing (16).

  • Dehydration

Shedding pounds quickly can result in dehydration, which is usually accompanied by such unpleasant side-effects as low energy levels, constipation, headache, mood swings, and muscle cramps.

Rapid weight loss is quite harmful since it can even cause severe dehydration, which, as research shows may in turn lead to apathy, mood swings, vomiting, nausea, sleepiness, and increased mental fatigue.

The above-presented are only a few of numerous risks of following a seemingly easy diet to lose 15 pounds in two weeks. So, do you still feel like it is worth it?

Calorie Intake To Lose Weight

Now, is it possible to lose 15 pounds in two weeks for women or men? The required daily calorie intake varies depending on a lot of factors, such as age, sex, height, initial weight, level of physical activity, and others (5).

The data states that an average adult woman may require from 1600 to 2400 calories a day. For an average adult man, these numbers differ and are from 2000 to 3000 calories a day. Since with age, the basal metabolic rate (BMR) of a person tends to decrease, so does the daily energy requirements (5).

As you already know, it is recommended to reduce your daily energy intake by 500 calories if you aim at a safe weight loss. In such a way you will be able to burn 3500 calories a week which equals the recommended 1 pound of fat (20).

You don’t need to starve yourself and spend hours in the gym to lose half of your weight, since shedding even 5-10% of your weight can significantly improve your health (10).

Various Physical Activity: Healthier Way To Lose Weight

It is general knowledge that regular physical activity can significantly improve your overall health and make you feel better. Another great benefit of regular workouts is healthy weight loss. Regular exercise can help you increase muscle mass, boost your metabolism and make you burn more calories even when you rest, which is tremendous for those who want to burn a couple of excess pounds of fat. It also increases your calorie expenditure, adding to the calorie deficit created by the weight loss diet, and leading to better results (14).

That is why it is recommended that when you try to slim down, you need to increase your level of physical activity and make regular exercise your daily routine. Any type of exercise is better than no exercise. And since there are so many types of effective workouts out there, you are sure to find the one that could fit you like a glove. So, here are some of the most popular exercises for weight loss:

  • Running

Running is a cardio exercise that makes your blood pump faster and lungs work harder. Cardio is overall very effective at helping people burn calories, often requires little to no equipment, and can be performed by anyone no matter the age or fitness level.

The 2015 meta-analysis found that daily running has a positive effect on a wide plethora of health factors, such as body mass, body fat, resting heart rate, triglycerides, and HDL cholesterol.

  • Resistance Exercise

Resistance training has proven to be very effective at building muscle and burning calories. It is beneficial for people who want to slim down since increased muscle mass leads to an increase in the resting metabolic rate, which, as was mentioned before, makes your body burn more calories even at rest. You can incorporate some resistance training in the form of weight lifting into your workout routine (19).

  • High-Intensity Interval Training (HIIT)

This type of workout is one of the best ways to burn some extra calories. The HIIT is a training that includes short periods of a high-intensity exercise, which depending on the type of HIIT are followed by the exercise of low intensity or rest periods that last a similar amount of time. The duration of each part of the cycle may vary from less than 45 seconds to a couple of minutes.

A review that compared moderate-intensity continuous training and HIIT found that they both promote a similar reduction of total body fat percentage, but HIIT was more effective at reducing a total absolute fat mass.

The Bottom Line: Is It Safe To Lose 15 Pounds In Two Weeks?

You have now reached the end of this swoop through the answer to this question. As you have seen from the article, rapid weight loss is unsafe, and the better option is to set realistic goals and slim down gradually. So, the answer to the question “Is it safe to lose 15 pounds in two weeks?” is a definite no. Sticking to a dangerously restrictive diet can lead to a lot of health problems. If your goal is to lose weight in a healthy and sustainable manner, then you should stick to the recommendations of experts and lose weight by creating an adequate energy deficit. Before making any changes in your current dietary plan, or starting to follow a new one, your best advice is to consult a dietitian.
