How to Lose Weight Without Going on a Diet

Most people who want to lose weight have already tried. Maybe it was a low-carb plan, a juice cleanse, or an app that set your calories so low you were hungry by midafternoon. It worked for a few weeks. Then life got busy, the plan fell apart, and the weight came back.

If this sounds familiar, please know that it is not a matter of willpower. Most strict diets are difficult to maintain for more than a short period of time, especially once work schedules, family events, and the colder months come into the picture. In addition, the extra weight can continue to affect your body, adding strain to your back, hips, and knees during everyday tasks.

Thankfully, there are ways to lose weight that do not require you to follow a strict diet. Below, we will cover the reasons crash diets often do not work, several everyday habits that may be easier to maintain, and how to read the labels on the foods you buy.

Why Don't Crash Diets Work?

Diets that offer fast results can be appealing. However, very restrictive plans are often hard to follow for long, and the weight that comes off quickly does not always stay off.

Some of the most common issues with crash diets are as follows:

  • Hunger and burnout: Plans that leave you feeling hungry or deprived for weeks at a time are difficult to keep up, and many people stop once they reach that point.
  • Lost muscle: Some of the weight lost during a diet may come from muscle. Regular physical activity can help counter this.
  • No lasting skills: A 21-day meal plan tells you what to eat for 21 days. It doesn't teach you how to pull together a quick dinner on a Tuesday night when you're worn out.
  • Weight regain: When the diet ends and you go back to your previous eating habits, the weight often returns.

In fact, people who lose weight gradually at a pace of about 1 to 2 pounds per week are more likely to keep the weight off than those who lose it more quickly.

What Can Help Instead?

Rather than cutting out entire food groups, it may help to focus on one or two small goals at a time. For example, you might drink water in place of soda, or add a serving of vegetables to dinner a few nights a week.

Eat Mostly Whole Foods

Whole foods are foods that are in their natural state or only lightly processed, such as fruits, vegetables, whole grains, eggs, lean meats, nuts, and seeds. Choosing these more often than packaged snacks and convenience foods is a good place to begin.

This does not mean you have to give up the foods you love. A balanced eating plan can still include a treat from time to time, though it is wise to limit sugary drinks, sweets, and alcohol.

Move More and Sit Less

Many jobs and daily routines involve long stretches of sitting. Adding short walks throughout the day can make a difference over time. Locally, the Idaho Falls Greenbelt is a convenient place for a walk in the warmer months, and indoor options can help once winter weather sets in. If pain makes it hard to stay active, our team can help you find a safe place to start.

Practice Mindful Eating

Mindful eating just means paying attention while you eat. It's easy to finish a bag of chips during a TV show, or a sandwich on the drive home, without really noticing either one.

To slow down, try not to let yourself get so hungry that you grab whatever is closest. Use a smaller plate. Set your fork down between bites. You'll have a better chance of stopping when you're satisfied, not when the plate is empty.

Surround Yourself with Support

Making changes is often easier with a support system, whether that be your spouse, friends, or even a coworker with similar goals. 

Regular follow-up visits with a healthcare provider can also help you track your progress and make adjustments to your plan when needed.

How to Read a Food Label

Words on the front of a box only tell you part of the picture. The Nutrition Facts label and ingredient list on the back give you the details.

Here is what to look for:

  • Added sugars: This line counts sugars added during processing, along with sugars from syrups, honey, and table sugar. Eating a lot of added sugar can make it harder to get the nutrients you need while staying within your calorie needs.
  • Ingredient list: This shows what is actually in the product. If you buy honey, for example, honey should be the only ingredient listed.
  • Percent Daily Value (%DV): As a general guide, 5% DV or less of a nutrient per serving is considered low, and 20% DV or more is considered high. Look for more fiber, calcium, and potassium, and less saturated fat, sodium, and added sugars.
  • Serving size: Every number on the label refers to one serving, not the whole package. If a container holds four servings, then finishing it would add up to four times the calories listed.

When Weight Loss Is More Complicated

For some people, healthy habits lead to steady progress. Others have a more complicated journey. Medications, medical conditions, hormones, genetics, stress, sleep, and age can all affect weight, and none of these come down to willpower.

Pain can add another layer. Excess weight is linked to back pain, hip pain, knee and ankle pain, and plantar fasciitis. Unfortunately, that pain can make it harder to move, which creates a frustrating cycle.

If you have a medical condition or take medication that may affect your weight, it is a good idea to speak with a provider before starting a new plan.
