How to Gain Weight with Diabetes

If you’re living with type 2 diabetes or prediabetes, chances are you’ve browsed the wild west web and found lots of information about losing weight. But what if your goal is the opposite, to gain weight?

Gaining weight while managing blood sugar and keeping your A1c in check can feel like walking a tightrope.

But don’t worry—you’re not alone, and with the right approach, it’s absolutely possible to gain healthy weight in a way that supports good blood sugar levels and optimal diabetes health.

Let’s break down the key steps to gaining weight with diabetes without sacrificing blood sugar control, based on sound nutritional science.

Step 1: Focus on Nutrient-Dense Foods

When you’re trying to gain weight, it’s tempting to turn to high-calorie junk food like chips, pastries or sugary drinks.

But these won’t do you any favors, as they wreak havoc on your blood sugar levels and lead to other health complications.

Instead, choose nutrient-dense, low carb foods that provide essential vitamins, minerals and healthy fats to support your overall health.

Here are some great options:

• Healthy Fats: Foods like avocados, nuts seeds, olive oil, and fatty fish (like salmon or mackerel) are calorie-dense and low in carbohydrates. These fats help you gain weight while supporting heart health and reducing inflammation.
• High-Quality Protein: Prioritize proteins such as eggs, poultry, meats like beef and lamb, tofu or tempeh. Protein is essential for building muscle and preventing unwanted weight gain from fat alone.
• Non-Starchy Vegetables with Healthy Fats: Add butter, olive oil or a sprinkle of cheese to veggies like broccoli, spinach or zucchini for extra calories.

Step 2: Eat More Calories

Generally we don’t recommend people even think about calories, but for weight gain we do need to consider it, as increasing your daily caloric intake or ensuring adequate daily calories will be key to gaining some weight, or preventing further weight loss.

We help our members work out the right amount of calories in our Diabetes Weight Gain Program.

When you’re trying to gain weight, it can be hard to consume enough calories in three meals a day.

Eating smaller, more frequent meals and including snacks can sometimes make it easier to reach your calorie goals without feeling overly full.

For example:

• Start your day with a hearty omelet cooked in butter or olive oil, with avocado on the side.
• Snack on a handful of nuts and seeds or some full-fat yogurt with a sprinkle of chia seeds.
• Add a mid-afternoon snack like cheese cubes paired with a few olives or low carb crackers.
• End your day with a protein-rich dinner, like chicken thighs and roasted vegetables drizzled with olive oil.

Tip: Consistency is key. Set reminders if you’re prone to skipping meals or find it difficult to eat regularly.

Step 3: Prioritize Protein for Muscle Growth

When you gain weight, you want to focus on building lean muscle, not just adding fat. Muscle gain not only helps you achieve a healthy body composition but also improves insulin sensitivity and blood sugar regulation.

Spread your protein intake evenly across meals to maximize muscle synthesis.

Pair your protein-rich meals with resistance training to build muscle effectively. Activities like lifting weights, resistance band workouts, or even bodyweight exercises (like push-ups or squats) are excellent for preserving and building muscle mass.

Step 4: Add Calorie Boosters to Your Meals

One of the easiest ways to increase your calorie intake is to add small, calorie-dense ingredients to your meals. These additions pack a punch without requiring you to eat much more food.

• Add olive oil to roasted vegetables or drizzle over salads.
• Top meals with cheese or dollop on sour cream.
• Blend in nut butter or coconut cream to smoothies.
• Sprinkle seeds like chia, flax or hemp on yogurt, salads or soups.

These small changes can add 100–200 calories to a meal or snack without adding significant carbs, which is what you want in order to gain weight but not spike blood sugar levels.

Plus, smoothies are a great way to get 600-800 calories into your daily routine.

Step 5: Monitor Blood Sugar Closely

As you increase your calorie intake, keep a close eye on your blood sugar levels. While using our T2Diet lower carb approach helps stabilize blood sugar, you’ll want to ensure that any new foods or increased portion sizes don’t cause spikes.

Use a blood glucose monitor to test after meals. Aim to stay under 140 mg/dL (7.8 mmol/L) two hours after eating.

Step 6: Be Patient and Consistent

Gaining weight healthily is a gradual process. You might not see results overnight, but consistency will pay off.

Focus on building sustainable habits and fueling your body with high-quality foods.

Remember, small increases in calorie intake over time will lead to steady, healthy weight gain.

A Word About Medications

If you’re taking medications GLP-1 receptor agonists (e.g., Ozempic or Wegovy), these will work against you as they are designed for weight loss.

These medications can suppress appetite or impact how your body metabolizes food.

Metformin can also make it more difficult to gain weight—it’s not a weight loss drug but can promote slight weight loss in some people.

Conclusion

Gaining weight with diabetes is all about balance.

By focusing on nutrient-dense foods, increasing your calories, spreading your meals throughout the day, prioritizing protein, and monitoring your blood sugar, you can achieve your weight gain goals while keeping your A1c in check.

Take it one step at a time; healthy weight gain isn’t a sprint.

With the nutrition right plan in place, you’ll build not just weight but also strength and energy, contributing to optimal diabetes health.
