What Should I Eat Before 6 Months of Weight Loss Surgery?

Now, you may worry about what I have to eat exactly to lose weight and prepare myself for weight loss surgery. Here’s the list of diets you should add to your six-month diet before weight loss surgery. 

Focus on Protein-Rich Foods

Protein helps your body to prepare for the surgery. It helps maintain muscle mass, keeps you feeling full, and aids in faster recovery. You can add proteins like chicken, turkey, fish, eggs, and low-fat dairy in every meal. 

You can choose tofu, beans, and lentils if you are vegetarian. Protein shakes can also be a good supplement, but it’s best to consult a professional for more personal advice. 

Take More Fruits and Vegetables

Fruit and vegetables are essential to add to your diet. They are rich in vitamins, and minerals vital for overall health. Leafy greens, berries, carrots, and broccoli are all excellent choices. However, you should be careful regarding portions, especially fruits, as fruits can be high in natural sugar. 

Stay Hydrated and Avoid Liquid Calories

Hydration is the easiest but essential addition to your diet plan. Water should be your go-to beverage. Staying hydrated helps with digestion and overall body functioning. However, you need to avoid sugary drinks, alcohol, and excessive caffeine, as these can add unnecessary calories and dehydrate you.

Note: Your dietitian can help you by providing a diet plan that fits your current health and weight conditions. Here is the 6-month diet plan. However, it’s better to consult a health professional beforehand. 

Month 1: Assess and Adjust Your Current Diet

First of all, you need to assess your current dieting plan. Which plan are you following now, your eating habits, and which food are you taking? Here is the step-by-step process of assessing and adjusting your diet in the first month:

  • Take note of what you eat daily.
  • Identify patterns like emotional eating or frequent snacking.
  • Cut out processed foods and sugary snacks.
  • Eat healthy foods like lean proteins, fruits, and vegetables instead.
  • Gradually reduce your intake of fast food and sugary drinks.
  • Start by reducing portion sizes slightly at each meal.
  • Focus on eating at regular intervals, ideally every 3-4 hours.
  • Avoid late-night snacking by setting a cut-off time for eating.

Month 2: Focus on Nutrient-Rich Foods

You need to add food that is rich in nutrients to your plan. These essential vitamins and minerals help you maintain overall health and fulfil your body’s needs. 

  • Take vegetables and fruits on regular basis. Aim for the different varieties to maximise your nutrient intake.
  • You should also need to opt for lean proteins. Include chicken, fish, tofu, or beans to support muscle maintenance.
  • Whole grains are essential to include in your daily diet. For lasting energy, opt for brown rice, quinoa, and oats.
  • Limit snacks like chips, cookies, and sugary drinks to stabilise blood sugar and promote weight loss.

Month 3: High Protein Intake

Protein is an element that you should never skip in your diet. However, before undergoing weight loss surgery, you should pay special attention to it. 

  • Try to include some quantity of protein in every meal to support muscle maintenance and overall health.
  • Take lean meats like chicken and turkey, fish, eggs, and low-fat dairy. For plant-based options, consider beans, tofu, lentils and quinoa.
  • Try a grilled chicken salad, a veggie omelette, or a smoothie with protein powder. Protein shakes can also be convenient ways to boost your intake.

Month 4: Hydration and Cutting Out Liquid Calories

In month 4, you must pay special attention to hydration and skip all the unhealthy liquid drinks. Water helps remove toxins, supports digestion, and can even help control hunger. On the other hand, sugary drinks, alcohol, and excess caffeine can add unnecessary calories, slow your progress, and even cause dehydration.

  • You should drink minimum 8 glass of water daily. Hydration keeps your body functioning well and aids in weight loss.
  • Cut out sodas, sweetened teas, and alcoholic beverages. You should also limit the coffee and energy drinks to avoid extra sugar and calories.
  • Carry a water bottle everywhere, flavour your water with fresh fruits or herbs, and opt for herbal teas and calorie-free alternatives.

Month 5: Practicing Mindful Eating

In the 5th month, you must be careful about what you eat. You have to assess carefully how your body is responding to that diet. It will help you to minimise stress-related eating. 

  • Take the time to eat each meal without distractions. Chew slowly, appreciate the flavours, and let your body naturally tell you when you’re satisfied.
  • Before eating, ask yourself if you’re hungry, bored, or stressed. During meals, pause halfway to check in with your hunger levels.
  • Sort out triggers that lead to emotional eating and look for healthier coping strategies like going for a walk or practising deep breathing.

Month 6: Preparing for the Post-Surgery Diet

When you get into month 6 of the pre-surgery diet, you must prepare for the changes. You must take smaller, more frequent meals and understand the dietary phases you’ll follow after surgery. This preparation will help your body adjust according to the diet you have to follow after surgery. 

  • Start eating 5-6 small meals daily to get your body used to the post-surgery routine. Focus on portion control and careful eating.
  • Learn about the different stages you’ll go through after surgery, from liquids to pureed and solid foods. 

What Foods to Avoid Before Bariatric Surgery?

You don’t need healthy foods, so avoid a diet that is not good for your health. Here’s the list of foods that you should avoid in any case before weight loss surgery:

Sugary Foods and Drinks: Sweets, sodas, and other sugary items can increase blood sugar and contribute to weight gain. These empty calories are not nutritional and can hinder your weight loss efforts.

Fried and Fatty Foods: Fried chicken, French fries, and other greasy foods are high in unhealthy fats. These foods can affect your digestion and add extra pounds. These are also difficult to break down, which can be problematic post-surgery.

White Bread and Refined Carbs: Foods like white bread, pasta, and pastries are refined carbohydrates that can cause blood sugar fluctuations. As a result, it will leave you feeling hungry soon after eating. You can take whole grains instead.

Alcohol: Alcohol is highly hamrful and affects your liver, which is already under stress from carrying extra weight. It’s best to cut out alcohol entirely before your surgery.

High-Sodium Foods: Processed snacks, canned soups, and fast food are often loaded with sodium. It can lead to high blood pressure. Reducing your salt intake is essential for a smoother surgery.

Carbonated Beverages: Sodas cause bloating and discomfort. The carbonation can stretch your stomach, making it harder to adjust to the smaller portions you’ll need post-surgery.

Caffeinated Drinks: Excess caffeine from coffee, energy drinks, or certain teas can dehydrate you and cause increased heart rate. So, you should skip it from your diet.

How to Prepare Myself for Bariatric Surgery?

There are some other practices that you can add to your routine to prepare yourself for bariatric surgery:

Follow a Pre-Surgery Diet: Your doctor will likely recommend a special diet to shrink your liver. Follow that diet plan strictly to make the process easier.

Start Exercising: Light activities like walking can help you build strength and improve your recovery. Do it for at least 30 minutes a day.

Quit Smoking: If you smoke, you should leave it immediately. It can increase the risk of complications during and after bariatric surgery.

Stay Hydrated: Drink a lot of of water throughout the day. Staying hydrated is a must to keep your body functioning well before surgery.

Stress Management: Stress can ruin your diet and weight loss efforts. So, try different techniques like exercise, walking, journaling, or meditation to minimise its effects on the surgery. A study by PubMed reveals that a person with stress is less likely to lose weight before weight loss surgery. 

Post-op Diet After Bariatric Surgery

This pre-op surgery will help you to accept the sudden changes in your digestive system. In the immediate days after surgery, your diet will be liquid-based. It will allow the stomach to heal without being stretched. 

You can start with clear liquids like broth, water, and sugar-free gelatin. Gradually, you’ll move on to protein shakes and other nutrient-dense liquids to ensure you’re getting enough nutrition.

After a few days, you’ll transition to pureed and soft foods. During this time, you should focus on high-protein, low-sugar options. Proteins are essential to add to your diet at this stage. However, avoid sugars to prevent complications like dumping syndrome.

Portion control is also essential to consider while eating. Your new stomach size will only hold a small amount of food, so it’s important to eat slowly. Overeating can lead to discomfort.
