Ice Hack Diet: Does it Really Melt Belly Fat?

The Ice Hack for Weight Loss - Does It Really Work?

Losing weight can be a frustrating endeavor. With so many diets and exercise programs out there, finding something that works long-term is a challenge. Recently, a new weight loss trend called the ice hack diet or alpine diet has gone viral on TikTok and other social media platforms. Proponents claim that merely drinking ice cold water can help burn calories and lead to weight loss. But is there any truth to these assertions? Let's take a deeper look at the ice hack and whether it lives up to the hype.

What is the Ice Hack?

The ice hack is exactly what it sounds like a hack that utilizes ice to promote weight loss. The diet first gained fame on TikTok, with numerous videos demonstrating how to follow the ice hack. People using the hashtag #icehack have racked up over 240 million views on TikTok so far.

The premise of the ice hack is simple. Followers are instructed to drink at least one glass of ice cold water first thing in the morning on an empty stomach. Some versions advise drinking an entire pitcher of icy water. The water must be as cold as possible, either chilled overnight or with lots of ice cubes. Additionally, fans of the diet recommend sipping on ice water throughout the day as a replacement for high-calorie beverages.

Alleged Benefits of the Ice Hack

According to ice hack devotees, there are a number of benefits to drinking icy cold water daily:

• Burns calories - Drinking icy water forces your body to warm the water to body temperature. This acceleration of thermogenesis supposedly burns extra calories.
• Suppresses appetite - The cold water is said to dull hunger pangs, allowing you to consume fewer calories.
• Increases metabolism - Some proponents claim icy water can give your metabolism a boost, equating to more calories burned.
• Detoxifies - Many believe starting your day with cold water has a cleansing effect, flushing toxins from your system.

In addition, replacing sugar-sweetened or high-calorie beverages with chilled water means consuming fewer liquid calories during the day. Whether true weight loss comes from the metabolic impact of cold water or merely swapping out higher calorie drinks remains questionable.

Assessing the Science Behind the Ice Hack

When looking at the validity of a diet trend, it always helps to examine the specific claims and whether they are backed by scientific research. So what does the science have to say about the proposed benefits of icy water?

Calorie Burn

One of the primary allegations around the ice hack is that it accelerates calorie burn by forcing the body to warm the frigid water to an internal temperature of 37C (98.6F). The process of your body heating up cold water is known as thermogenesis. And it's true that your metabolism does rev slightly when processing significantly cold food and drinks.

Studies show that drinking 17oz (500ml) of ice cold 40F (4C) water can boost resting metabolism by up to 30% for about an hour. However, the actual number of calories burned is fairly minimal. Research indicates the increase in metabolic rate translates to an extra 24-41 calories burned. To put that in perspective, you'd have to drink 17oz of icy water six times per day just to burn one pound of fat over a month. So while the thermogenesis effect is real, it's unlikely drinking cold water can produce significant calorie burn on its own.

Appetite Suppression

Another claim around the ice hack is that it dulls hunger pangs and cravings. Some research lends credibility to this assertion. Studies demonstrate that drinking 500ml of chilled water can temporarily reduce feelings of hunger and desire to eat. Scientists believe Exposure to cold temperatures may activate the sympathetic nervous system which regulates satiety signals in the brain. Though more research is needed, evidence indicates icy water may help curb appetite short-term.

Metabolism Boost

Beyond the small uptick in calories burned after drinking cold water, there is limited evidence supporting the idea that the ice hack can permanently boost your resting metabolism. Any increase in metabolic rate from the thermogenesis effect is minor and temporary. One week-long study did find that drinking 500ml of chilled water temporarily boosted resting energy expenditure. But there are no long-term studies showing sustained improvements in baseline metabolism.

Detoxification

Detoxification, or the idea that something can flush toxins from your body, is more of a myth not backed by science. Our kidneys, liver, skin, and gastrointestinal tract already effectively eliminate wastes and toxins when functioning properly. Drinking icy water in the morning has no proven detoxification effects. But staying well hydrated in general is important for health.

Potential Downsides of the Ice Hack

While drinking plenty of water is healthy, there are some potential downsides to watch out for with the ice hack specifically:

• Temporary discomfort - Some people may experience abdominal discomfort, bloating, or diarrhea from drinking excessive cold water, especially first thing in the morning.
• Nutrient absorption - There is some evidence that icy water during or directly after meals may hinder proper stomach acid production and nutrient absorption.
• Blood sugar spikes - Consuming very cold water may cause a spike in blood sugar due to the body quickly absorbing the cold liquid.
• Dental sensitivity - Extreme temperatures can provoke dentin hypersensitivity in some people, causing dental pain.
• Masking underlying issues - Relying on the ice hack alone risks ignoring potential health conditions contributing to weight gain.

As with any diet trend, it's best not to go overboard. Drinking reasonable amounts of ice cold water as a substitute for high-calorie beverages is likely fine. But excessive intake could potentially impact digestion, blood sugar regulation, and dental health in some individuals.

Healthy Use of Cold Water for Weight Loss

While the concept of thermogenesis from icy water may be somewhat exaggerated, there are beneficial ways you can incorporate chilled water into a healthy lifestyle:

• Substitute for high-calorie drinks - Swap sugary soda, juice, sports drinks, coffee drinks, etc. for plain ice water. Saves calories and sugar.
• Drink before meals - Consume 500ml of cold water 30 minutes before meals to potentially temper appetite.
• Set daily goals - Drink eight 8oz glasses of ice water per day to stay hydrated.
• Infuse with fruits/herbs - Add citrus, berries, cucumbers, mint, etc. to make water tastier.
• Don't guzzle - Sip cold water slowly rather than gulping down large amounts too quickly.

The key is moderation. Let your body acclimate to colder water temperatures and complement increased water intake with an overall healthy diet and regular exercise. Don't rely on icy water alone to produce significant weight loss.

The Bottom Line on the Ice Hack

In summary, here's the real scoop on using icy water for weight loss:

• Drinking 500ml of 40F water temporarily boosts calorie burn by about 24-41 calories.
• Frigid water may suppress appetite for short periods.
• No proof that ice hack produces lasting increases in metabolism.
• Replacing high-calorie drinks with cold water can reduce daily calorie intake.
• Overdoing it may cause discomfort or dental sensitivity in some.
• The ice hack alone without diet and exercise is unlikely to produce major weight loss.

While drinking chilled water can be part of a healthy weight loss plan, it should not be viewed as a magic bullet for melting away pounds. Talk to your doctor before attempting any new diet trend and focus on developing overall healthy eating and lifestyle habits.
