A Functional Medicine Approach to Nourishing Your Body and Supporting Healthy Weight Gain
When people talk about nutrition, most of the conversation revolves around losing weight.
But what about the people who are struggling to gain it?
At Functional Medicine Los Angeles, we often meet individuals who feel frustrated because no matter how much they eat, the scale barely moves.
Others may gain weight, but not in the way they hoped. Instead of feeling stronger, they feel sluggish, bloated, or notice that the weight is settling in areas that don’t support their health goals.
The truth is that healthy weight gain is about much more than simply eating more food.
It’s about helping your body build:
✅ Strength
✅ Muscle
✅ Energy reserves
✅ Resilience
Not simply accumulating body fat.
Whether you’re recovering from illness, dealing with a fast metabolism, struggling with appetite, or looking to build lean muscle, the quality of the food you eat matters just as much as the quantity.
Why Healthy Weight Gain Matters
Many people assume being thin automatically means being healthy.
But being underweight or struggling to maintain weight can sometimes be associated with:
✅ Low muscle mass
✅ Nutrient deficiencies
✅ Fatigue
✅ Reduced strength
✅ Poor recovery
✅ Hormonal imbalances
Healthy weight gain focuses on supporting the body’s ability to function, heal, and thrive.
The goal isn’t just a higher number on the scale.
The goal is a stronger, more nourished body.
Focus On Nutrient-Dense Foods
One of the biggest mistakes people make when trying to gain weight is relying on junk food.
While highly processed foods may add calories quickly, they often provide very little nutritional value.
Instead, focus on foods that deliver both calories and nutrients.
Nutrient-Dense Foods to Include:
✅ Avocados
✅ Eggs
✅ Salmon
✅ Grass-fed beef
✅ Greek yogurt
✅ Nuts and nut butters
✅ Sweet potatoes
✅ Oats
✅ Quinoa
✅ Beans and legumes
✅ Olive oil
These foods provide vitamins, minerals, healthy fats, protein, and energy that support healthy weight gain.
Don’t Fear Healthy Fats
Healthy fats are one of the easiest ways to increase calories without feeling overly full.
They also play an important role in:
✅ Hormone production
✅ Brain function
✅ Cell health
✅ Nutrient absorption
Examples of healthy fats include:
✅ Avocados
✅ Extra virgin olive oil
✅ Almonds
✅ Walnuts
✅ Chia seeds
✅ Flaxseeds
✅ Natural peanut butter
Adding a tablespoon of olive oil to vegetables or spreading nut butter on toast may seem small, but those additions can make a meaningful difference over time.
Prioritize Protein for Muscle Growth
If you’re trying to gain healthy weight, protein should be a daily priority.
Protein helps support:
✅ Muscle growth
✅ Tissue repair
✅ Recovery after exercise
✅ Long-lasting fullness
Protein-rich foods include:
✅ Chicken
✅ Turkey
✅ Eggs
✅ Fish
✅ Cottage cheese
✅ Greek yogurt
✅ Tofu
✅ Lentils
A common mistake is increasing calories without increasing protein.
This often leads to gaining more body fat than muscle.
Carbohydrates Are Not the Enemy
Carbohydrates provide energy that helps fuel workouts, recovery, and daily activities.
Instead of avoiding carbs, focus on quality sources such as:
✅ Sweet potatoes
✅ Brown rice
✅ Oats
✅ Quinoa
✅ Fruit
✅ Whole-grain bread
Balanced carbohydrates can help replenish energy stores and support muscle-building goals.

The Functional Medicine Perspective
At Functional Medicine Burbank, healthy weight gain is about more than calories.
We also consider factors such as:
✅ Gut health
✅ Nutrient absorption
✅ Hormone balance
✅ Stress levels
✅ Sleep quality
Because if the body is struggling to absorb nutrients or recover properly, gaining healthy weight can become much more challenging.
Functional Medicine Testing is often used to identify underlying nutrient deficiencies and absorption issues.
