Does it work for weight loss

In a nutshell, yes. However, fat loss will occur due to being severely under your daily energy requirement (calories). In theory, it doesn’t matter if its labeled cabbage soup or something else entirely. As long as you are in a calorie deficit, you will lose weight.

How much weight can you lose?

Its claimed you could lose up to ten pounds within seven days. However, due to how little you eat, this will be a combination of muscle, water, and fat loss. Due to the excessive restriction of calories, you will put weight back on once you go back to regular eating.

Furthermore, the loss of muscle isn’t beneficial when trying to lose weight. As a matter of fact, the increased muscle mass will increase metabolism yielding better results long term.

Potential hazards following restrictive calorie diets

As with any diet that promotes rapid fat loss, there are dangers. When diets are as restrictive as the one mentioned, you have to way up the pros and cons. in other words, is it worth it.

The cabbage soup diet can help you lose up to 10lbs in one week! However, it’s important to remember, out of that 10lbs of weight loss, only 34% will be fat. The other 66% of weight loss will be made up of muscle and water loss (1)

The main dangers from these types of diets are from the lack of calories you are consuming daily. Its highly unlikely that you will meet your daily nutritional needs. This includes your macronutrients and vitamins and minerals.

Virtually all the foods on the allowed to eat list contain very few calories. Most experts agree that 1500 calories for men and 1200 calories for a woman is the minimum you should consume in a day. In this particular diet, you will struggle to hit 1000 per day. (2)

Possible side effects with an extremely low-calorie diet

As previously mentioned, a low-calorie diet can cause problems. Below I will outline some of the side effects this diet may cause.

Muscle Wastage

Due to the low protein, your body will draw upon your muscles for energy. As stated, only about 34% of the weight loss is down to losing body fat (during the first week). Losing muscle will seriously slow down any weight loss attempt once you come off this diet. Not only that, with an extreme diet, your body will respond by slowing down the metabolism, decreasing the number of calories your body burns at rest.

Dizziness, weakness, and lightheadedness

Many people have reported the above symptoms when on the cabbage soup diet. This is usually down to the lack of nutrients. However, don’t be too worried about vitamin and mineral deficiencies. There isn’t a significant risk as the diet only lasts for seven days.

Due to the low nutrients and the body’s requirements, it’s highly likely you will experience dizziness, weakness, and lightheadedness.

Furthermore, you may find yourself feeling very tired from the lack of energy.

Gallbladder issues

A low-calorie diet may cause gallbladder problems. The purpose of your gallbladder is to release juices that digest fats. However, on this diet, you eat little fat causing the gallbladder to not empty. If the gallbladder doesn’t empty, it may form stones!

If you develop gallstones, then you may need surgery to remove them. At the very least, you will need medication, and the medicine may cause side effects. Gallstones may not present any symptoms, or you could be in excruciating pain.

Flatulence and cramping

Flatulence and cramping are extremely common with the cabbage soup diet. The reason is, that you are having a lot of fiber.

Weight gain after day 7

It’s highly probable you will gain most of the weight back. Once you start eating more calories, your body will try and replace the water and muscle loss.

Final Thoughts

Although the science is limited about the 7-day cabbage soup diet, the likelihood you will lose weight is high. However, as mentioned, you won’t be losing a great deal of fat! Due to the diet only lasting seven days, the chances of you having any severe side effects are slim.

That said, even with a low chance of side effects, I would avoid starting this diet. It’s incredibly bland and sacrifices a lot of food for such small short-lasting results.

There are much better diets out there, such as paleo or the 3-week diet plan. Paleo is more of a long-term plan and lifestyle change, whereas the 3-week diet is a shorter-term with fast results.

    Well, yeah. The 7-day cabbage soup diet sounds like a super restrictive diet. And what happens if you don’t like cabbage soup. People will surely substitute it for other food. That could cause even more problems mm. And, as for the list of potential issues, I, for one, wouldn’t go near it.

    Thanks for this enlightening post, Steven. It was a good read. 🙂
