Sous Vide vs Slow Cooker For Weight Loss

Are you on a quest to shed those extra pounds and achieve your weight loss goals? If so, you’re probably exploring various cooking methods to help you stay on track. Two popular options in the world of culinary techniques for healthier eating are sous vide and slow cooking.

In this article, you will have a look into sous vide vs slow cooker for weight loss. You’ll discover the benefits of each method and which one might be the right fit for your weight loss journey. So, grab your apron, and let’s get cooking!

What Is A Sous Vide?

Sous vide, a French term meaning “under vacuum,” is a culinary technique that has gained immense popularity in recent years. It involves sealing food in a vacuum-sealed bag and cooking it at precise low temperatures in a water bath for an extended period. This method offers several unique advantages for those looking to lose weight.

  • Preservation of Nutrients: Sous vide cooking excels at preserving the nutrients in your food1. Unlike traditional cooking methods that can lead to nutrient loss through high heat, sous vide’s gentle cooking process ensures that vitamins and minerals remain intact. This means you’ll get the full nutritional value of your meal without any compromise.
  • Controlled Portion Sizes: Weight loss often involves monitoring portion sizes, and sous vide makes this easier than ever. By cooking your food in vacuum-sealed bags, you have precise control over portion sizes, preventing overeating and helping you stick to your calorie goals.
  • Optimal Flavor Retention: One of the standout features of sous vide cooking is its ability to lock in flavors2. The vacuum-sealed bags prevent the escape of flavors, resulting in intensely flavorful dishes without the need for excessive fats or seasonings. This can help you satisfy your taste buds while keeping your calorie intake in check.
  • Consistent Cooking: Achieving consistency in cooking can be challenging, especially when you’re trying to create healthier meals. Sous vide eliminates the guesswork by ensuring uniform cooking temperatures throughout your food3. This prevents overcooking or undercooking, helping you avoid the temptation of reaching for unhealthy snacks due to culinary mishaps.
  • Reduced Need for Added Fats: In traditional cooking methods, fats and oils are often used to prevent food from sticking to pans or drying out. With a sous vide method, these added calories become unnecessary. The sealed environment keeps your food moist and succulent without the need for excess fats, promoting weight loss-friendly meals.

Now that you understand the benefits of sous vide cooking, let’s turn our attention to the slow cooker and see how it measures up in the battle of the kitchen titans.

What Is A Slow Cooker?

The slow cooker, also known as a crock-pot, has been a kitchen staple for decades. Its convenience and ease of use have made it a go-to choice for busy individuals and families. But how does it fare when it comes to aiding weight loss? Let’s explore the benefits.

  • Long, Low-Temperature Cooking: Like sous vide, the slow cooker operates at low temperatures. This slow and steady cooking process helps break down tough cuts of meat and infuse flavors, all while maintaining the integrity of the ingredients4,5. This means you can create tasty, satisfying meals without resorting to high-calorie additions.
  • Batch Cooking: Weight loss often involves planning and preparing meals in advance. The slow cooker’s generous capacity allows you to cook large batches of healthy dishes, saving you time and effort throughout the week. Having ready-to-eat, portion-controlled meals at your disposal can prevent impulsive, calorie-laden food choices.
  • Reduction of Unhealthy Ingredients: Slow cooker recipes often emphasize wholesome ingredients like lean meats, vegetables, and legumes. The extended cooking time allows these ingredients to release their natural flavors6, reducing the need for added fats or sugars. This results in nutrient-rich, lower-calorie meals that support your weight loss goals.
  • Satiety: Slow-cooked meals are often hearty and satisfying, helping you feel full and satisfied after eating. This can reduce the temptation to snack on high-calorie, low-nutrient foods between meals.
  • Hydration and Weight Loss: Slow cooking retains moisture in your dishes, preventing them from drying out. This not only enhances the taste but also helps keep you hydrated, which is essential for weight loss. Proper hydration can boost metabolism and reduce the likelihood of overeating, two crucial factors in your weight loss journey.

Sous Vide vs Slow Cooker For Weight Loss

To help you choose whether to embrace sous vide or stick with your trusty slow cooker, let’s pit them against each other in a nutritional face-off. We’ll examine how each method affects some common weight loss metrics:

Calorie Control

Sous Vide: Sous vide excels at precise portion control. With vacuum-sealed bags, it’s easy to weigh and monitor your ingredients, ensuring you stick to your calorie goals.

Slow Cooker: While the slow cooker doesn’t offer the same precision as sous vide, it still promotes calorie control through batch cooking and the use of healthy, whole ingredients.

Nutrient Preservation

Sous Vide: Sous vide’s gentle cooking process preserves nutrients exceptionally well, giving you the full nutritional value of your food.

Slow Cooker: Slow cooking also retains nutrients, but some water-soluble vitamins may leach into the cooking liquid over extended periods.

Flavor Enhancement

Sous Vide: Sous vide’s sealed environment locks in flavors, resulting in dishes that are intensely flavorful without the need for excessive fats or seasonings.

Slow Cooker: Slow cooking infuses flavors into your dishes, creating rich and satisfying meals with minimal effort.


Sous Vide: Sous vide cooking can provide satiety through precise cooking, flavor preservation, and the enjoyment of perfectly cooked, flavorful meals.

Slow Cooker: Slow cooker meals offer satiety through hearty and satisfying dishes, which can help reduce the temptation to snack between meals.

Convenience and Time Management

Sous Vide: Sous vide requires more precise temperature control and longer cooking times, which may not suit those with a busy schedule.

Slow Cooker: The slow cooker’s “set it and forget it” approach is perfect for individuals with hectic lives. It allows for batch cooking and minimal hands-on time.


Sous Vide: Sous vide cooking retains moisture, contributing to a juicy final product and potentially aiding in hydration.

Slow Cooker: Slow cooking also preserves moisture, helping you stay hydrated while enjoying your meals.

The decision between sous vide and slow cooker ultimately depends on your personal preferences, lifestyle, and weight loss goals. Both methods have their merits and can be valuable tools in your journey toward a healthier you.

Key Questions To Guide Your Choice

1. Which is easiest to use?

When it comes to ease of use, the slow cooker stands out for its user-friendly approach. All you need to do is prep your ingredients, place them in the slow cooker, set the timer, and let it work effortlessly. This convenience is particularly valuable for individuals and families with busy lifestyles looking for a hassle-free way to prepare healthy meals.

On the other hand, sous vide, with its precise temperature control and the need for vacuum-sealing, may initially seem more intricate. However, once you become accustomed to the process, it becomes less daunting. Modern sous vide machines are designed to be user-friendly and often come with pre-programmed settings. So, while it may require a bit more initial setup and attention, it’s not difficult to master.

2. Which creates less waste?

Reducing waste is not only good for the environment but can also benefit your wallet. Let’s explore the waste produced by sous vide and slow cooker methods.

Sous Vide Waste: Sous vide typically generates less waste when it comes to food because it allows for precise portion control. By sealing ingredients in vacuum bags, you can avoid overbuying or having food go to waste. However, the use of plastic bags and vacuum-sealing equipment can contribute to plastic waste, which may be a concern for some environmentally conscious individuals.

Slow Cooker Waste: Slow cooking often results in larger batch preparations, which can be an excellent strategy for reducing waste. Cooking in large quantities and refrigerating or freezing leftovers can minimize food waste. However, slow cooker recipes may involve using more disposable items like aluminum liners, which can contribute to waste.

To reduce waste in both cooking methods, consider using reusable silicone food storage bags with sous vide and explore ways to minimize disposable items in your slow cooker recipes. Additionally, purchasing ingredients in bulk and planning your meals efficiently can help further reduce waste.

3. Are sous vide and slow cookers safe?

Both sous vide and slow cookers are safe when used correctly. However, there are a few safety considerations to keep in mind.

Sous Vide Safety: To ensure safety when using a sous vide machine, make sure to:

  • Properly seal your food in vacuum-sealed bags to prevent water from entering.
  • Use food-grade bags and containers to avoid any potential harmful chemical leaching.
  • Follow recommended cooking times and temperatures to eliminate harmful bacteria while preserving food quality.

Slow Cooker Safety: Slow cookers are generally safe, but it’s essential to:

  • Ensure that the slow cooker is functioning correctly with no electrical issues.
  • Follow cooking times and temperatures to ensure that your food reaches safe internal temperatures.
  • Handle ingredients safely by refrigerating them promptly and avoiding cross-contamination.

Both methods have safety guidelines you should follow, so be sure to read the instructions and understand the best practices for each cooking technique.

4. Which costs more?

The cost of using sous vide versus a slow cooker can vary depending on your choice of equipment and ingredients.

Sous Vide Cooker Costs: Sous vide machines can range from affordable immersion circulators to high-end precision cookers. Vacuum sealers and bags also add to the cost. Additionally, sous vide recipes may require higher-quality ingredients to fully capture the method’s potential, which could increase your grocery bill.

Slow Cooker Costs: Slow cookers are generally budget-friendly and widely available. The main costs are the initial purchase of the appliance and the ingredients you use. Slow cooker recipes tend to use economical cuts of meat and simple ingredients, making it a cost-effective choice.

In terms of ongoing expenses, slow cooking is often the more budget-friendly option. However, it’s important to remember that the cost of equipment and ingredients can vary widely, and your specific preferences and choices will ultimately determine the overall cost.

Tailoring Your Choice To Your Weight Loss Goals

Now that you have a better understanding of the benefits of sous vide and slow cooker cooking, it’s time to align your choice with your specific weight loss goals and preferences.

Sous Vide for Precision and Nutrient Preservation: If you’re someone who values precise portion control and wants to maximize nutrient retention in your meals, sous vide may be your preferred method. It’s ideal for those who enjoy experimenting with various flavors and want to create restaurant-quality dishes at home while keeping a close eye on calorie intake.

Slow Cooker for Convenience and Batch Cooking: On the other hand, if you have a busy lifestyle and prefer a hands-off approach to meal preparation, the slow cooker is your ally. It’s perfect for batch cooking, which can save you time and reduce the likelihood of opting for unhealthy takeout. Slow cooker recipes often feature wholesome ingredients, making it a great choice for those who prioritize simplicity and convenience.

Combining Both Methods: Don’t feel restricted to choosing just one method. You can use both sous vide and a slow cooker to your advantage. For instance, you can sous vide proteins to perfection and then finish them in the slow cooker with a flavorful sauce for a convenient and delicious meal.

Balanced Diet and Exercise: While choosing the right cooking method plays a significant role in weight loss, it’s important to remember that a balanced diet and regular exercise are equally crucial. No cooking technique can replace the benefits of a healthy, well-rounded meal plan and an active lifestyle.


In the sous vide vs slow cooker showdown for weight loss, there is no clear winner. Both methods offer science-backed benefits that can aid you on your journey to a healthier weight. The key is to align your choice with your individual preferences, lifestyle, and goals.

For cooking sous vide, it provides precision, nutrient preservation, and flavor fusion, making it a top choice for those who enjoy experimenting in the kitchen and closely monitoring portion sizes.

On the other hand, the slow cooker’s convenience, batch cooking capabilities, and ability to create flavorful, nutrient-rich dishes with minimal effort make it a valuable tool for busy individuals and families.

Ultimately, the best approach to weight loss is one that you can sustain in the long term. Whether you opt to cook food using sous vide, the slow cooker, or a combination of both, remember that consistency and a balanced diet are the cornerstones of success. So, embrace the culinary adventure, savor your healthy creations, and take one step closer to your weight loss goals with every delicious bite.
