#VALUE!
If you’ve ever started a diet and found it hard to keep going, you’re not alone. There’s so much confusing information out there, with new trends popping up all the time. Sometimes, what feels like the right way to lose weight is actually what’s holding us back. Here are five things you might not know about diets that could be slowing down your progress.
Quick Fix Diets = Fast Weight Gain
It sounds great at first, lose five pounds in a week and feel lighter. But what usually happens is your body loses water and muscle, not fat. And as soon as you go back to eating normally, the weight comes back and sometimes even more than you lost. This is called the “yo-yo effect,” and it’s why fast diets often don’t work in the long run.
What to do instead:
Try to build healthy habits that last. Losing 1–2 pounds a week is a much better way to keep the weight off over time.
Calorie Counting Isn’t Everything
Many people think eating fewer calories always means weight loss. But not all calories are the same. For example, 500 calories of chocolate will affect your body differently than 500 calories of vegetables and protein. If you focus only on numbers and ignore what the food is made of, you might feel tired, hungry all the time, and end up overeating later.
What to do instead:
Don’t just look at how many calories something has. Choose foods with protein, healthy fats, and fiber to help you feel full and stay satisfied.
Eating Too Little Slows Your Metabolism
If you suddenly eat a lot less, your body tries to save energy. Your metabolism slows down and burns fewer calories. It may feel like a fast way to lose weight, but over time it makes it harder. You might also feel tired, dizzy, or have issues with hormones.
What to do instead:
Eat regular meals with enough food to keep your body working well and your metabolism active.
Overly Strict Diets Can Hurt Your Health
Some diets tell you to cut out carbs, fats, or dairy completely. This can work at first, but after a while, it may lead to missing important vitamins, losing muscle, or having digestive problems. Plus, strict diets can make you want the “off-limits” foods even more, leading to binge eating.
What to do instead:
Aim for balance. You don’t need to cut out entire food groups. Just try to pick healthier options within each one.
Not Sleeping Enough Can Mess Up Your Diet
Most people don’t realize that poor sleep can cause weight gain. When you don’t get enough rest, the hormones that control hunger go off balance. You feel hungrier, especially for carbs and sweets. You also feel more tired and move around less.
What to do instead:
Try to sleep 7–8 hours a night. A good night’s sleep helps control hunger, keeps your energy up, and supports your metabolism.
