How much do I really need to eat to recover from an Eating Disorder?

One of the most common questions I hear is:

"I've increased my food. Why hasn't my body changed yet?"

Maybe you've added a snack, challenged a fear food, or started eating breakfast again. These are huge steps, and they absolutely matter. But sometimes they still aren't enough for your body to begin repairing the effects of long-term under-fuelling. This can be incredibly frustrating. It can feel like you're trying so hard without seeing any reward.

The reality is that recovery often requires more food than your eating disorder thinks is "enough."

Recovery Isn't About Eating "Better". It's About Eating Enough.

Many people enter recovery believing they simply need to eat a little more than they were before. But eating disorder recovery isn't just about maintaining your body. Your body has a long list of jobs it has been putting on hold while energy has been scarce.

When food has been restricted, your body prioritises survival. Functions that aren't essential to keeping you alive are reduced or switched off.

These can include:

• Reproductive hormones and menstrual cycles

• Bone building and repair

• Growth and development (particularly in young people)

• Muscle repair

• Hair, skin and nail health

• Digestion

• Temperature regulation

• Concentration and memory

• Mood and emotional regulation

Before these systems can recover, your body first needs to feel confident that enough energy is consistently available.

Why Small Changes Sometimes Don't Feel Like They're Working.

Imagine your body has a long list of unpaid bills. If you've been restricting for months or years, you've built up an "energy debt." When you increase your intake, that extra energy doesn't immediately become available for things like getting your period back, feeling warmer, or having more energy. Instead, much of it is used to repay that debt. Repairing organs, restoring hormone production, rebuilding muscle, replenishing nutrient stores, and reversing the adaptations your body has made all require energy. Only once your body trusts that food is reliably available does it begin investing in these longer-term functions.

Your Body Needs Consistency.

It's common to think:

"Surely eating a bit more should be enough?"

But recovery doesn't work like topping up a nearly full tank. If your body has been under-fuelled for a long time, it often needs a significant and consistent increase in energy before it feels safe enough to repair. This is why eating more for a few days before cutting back again often isn't enough. Your body is looking for a consistent message:

"Food is available. You don't need to conserve energy anymore."

Signs Your Body Is Recovering:

Physical recovery looks different for everyone, but some signs include:

• Feeling warmer

• More stable energy throughout the day

• Improved concentration

• Better sleep

• More regular digestion

• Reduced food preoccupation

• Improved mood

• Increased strength

• Hormone recovery, including the return of periods

• Improved blood test results

• Better bone health over time

Many of these changes take weeks or months of adequate nutrition. Some, like improvements in bone density, can take much longer.

"But It Feels Like So Much Food..."

This is perhaps the hardest part of recovery. Many people worry they're eating "too much." The eating disorder often interprets adequate nutrition as excessive nutrition because its perception of "normal" has been shaped by restriction. Recovery intake can feel uncomfortable, not because it is wrong, but because your brain and body are recalibrating after a period of under-fuelling. Feeling full, eating more frequently, or needing larger portions doesn't mean you're doing recovery incorrectly. In many cases, it means you're giving your body what it has been asking for.

Trust the Process.

Recovery isn't measured by how little food you can get away with eating. It's measured by giving your body enough to repair, restore and thrive. If your body still isn't showing signs of physical recovery, it doesn't necessarily mean you've failed. It may simply mean your body needs more energy, more consistency, and more time.

That's why working with an eating disorder dietitian can be so valuable. Rather than guessing whether you're eating enough, you can have a plan that supports both physical healing and your relationship with food. Your body isn't asking for "too much." It's asking for enough.
