13 Reasons You’re Not Losing Weight

If losing weight feels harder than it used to, you're not imagining it.

After 50, changes in sleep, activity, muscle mass, hormones, medications and overall health can all affect your weight. That doesn't mean you're doing something wrong—or that you need to go on an extreme diet.

Instead, it may be time to look at some of the less obvious things that could be getting in the way.

Here are some common reasons the scale may not be moving.

1. You're Not Sleeping Well

Sleep can become more difficult with age. Hot flashes, aches and pains, stress, frequent nighttime bathroom trips and other issues can interfere with getting enough rest.

Too little sleep can affect hunger and appetite and may leave you too tired to be active the next day.

Try this: Make sleep part of your weight-management plan. Keep a regular bedtime, limit late-night screen time and talk with your health care provider if you're routinely having trouble sleeping.

2. You're Drinking More Calories Than You Realize

Coffee drinks, sweet tea, soda, juice and alcoholic beverages can add calories without making you feel especially full.

And those calories can be easy to overlook.

Try this: Make water your everyday beverage and pay attention to what you're adding to coffee and other drinks.

3. You're Waiting Until You're Starving to Eat

Going too long without eating can leave you extremely hungry by your next meal. That's when oversized portions and mindless snacking can become much more tempting.

Rather than trying to "save calories" all day, aim for balanced meals that include protein, vegetables, high-fiber carbohydrates and healthy fats.

4. You Eat Out More Than You Think

Restaurant meals can contain much larger portions than you would serve yourself at home.

Sauces, dressings, appetizers, desserts and drinks can also add up quickly.

You don't have to stop eating out.

Try this: Look for grilled or baked foods, vegetables and protein-rich choices. Consider taking part of your meal home before you start eating.

5. You're Sitting Too Much

You don't have to spend hours at the gym to become more active.

Long stretches of sitting can add up over the course of a day, especially if you have retired or your daily routine has become less active.

Try this: Break up sitting with short walks, household chores, gardening, errands or a few minutes of movement throughout the day.

Even small amounts of activity are better than none.

6. You're Eating Back the Calories You Burn

Exercise is important for your health, strength and mobility. But it's easy to overestimate how many calories a workout burns.

A long walk doesn't necessarily justify a large dessert or a high-calorie specialty drink afterward.

Try this: Think of exercise as something you do for your heart, muscles, bones and overall health—not simply as permission to eat more.

7. Alcohol May Be Adding Up

Wine, beer and cocktails all contain calories.

And alcohol can make it easier to snack on high-calorie foods or make less-healthy choices.

If you're trying to manage your weight, consider how often you drink and how much you typically have.

8. Stress Is Affecting Your Eating

Stress doesn't just affect your mood. For some people, it also changes eating habits.

You may find yourself reaching for cookies, chips, sweets or other comfort foods when you're stressed, bored or lonely—even when you're not physically hungry.

Try this: Before reaching for a snack, pause and ask yourself, "Am I actually hungry, or am I looking for a break?"

A short walk, phone call with a friend, music or another relaxing activity may help.

9. You're Making Too Many Last-Minute Food Choices

When you're hungry and don't have a plan, the easiest option often wins.

That might mean fast food, packaged snacks or whatever happens to be available.

Try this: Keep easy, nutritious foods on hand. Greek yogurt, fruit, nuts, eggs, vegetables, beans and other simple foods can make healthy choices easier.

10. You're Losing Muscle as You Age

This is an especially important consideration after 50.

As we get older, we can gradually lose muscle mass if we aren't doing enough resistance exercise and eating enough protein. Less muscle can affect strength, mobility and how many calories your body uses.

Try this: Talk with your health care provider about adding strength training appropriate for your fitness level. Resistance exercises can help preserve muscle and independence as you age.

11. Hormonal Changes May Be Playing a Role

For women, menopause brings major hormonal changes that can affect where the body stores fat, sleep and other factors related to weight.

Men can also experience age-related hormonal changes.

That doesn't mean weight gain is inevitable—but it does mean the strategy that worked at 35 may not work the same way at 55 or 65.

12. A Medication Could Be Contributing

Some prescription and over-the-counter medications can affect appetite, metabolism or fluid balance.

That doesn't mean you should stop taking a medication on your own.

Try this: If your weight changed after starting a new medication, ask your doctor or pharmacist whether weight gain is a possible side effect and whether there are alternatives.

13. A Health Condition Could Be Making Weight Loss Harder

Sometimes stubborn weight isn't simply about food or exercise.

Conditions involving the thyroid and other aspects of health can affect weight. If you're following healthy habits and still having unexpected changes in your weight, it's worth discussing with your health care provider.

Your doctor can help determine whether an underlying medical issue could be contributing.

The Bottom Line

If you're over 50 and the scale isn't moving, don't automatically assume you need to eat less and exercise more.

Look at the bigger picture.

Are you sleeping well? Moving throughout the day? Maintaining muscle? Drinking calories?

Eating because you're stressed? Taking a medication that could affect your weight?

And remember: your health is about more than the number on your bathroom scale.

A sustainable approach may involve improving your strength, energy, sleep, nutrition and mobility—not simply trying to become as light as possible.

If you've made consistent lifestyle changes and still can't explain significant weight gain or difficulty losing weight, talk with your health care provider. There may be a medical or medication-related reason that deserves attention.
