Why do plateaus happen even when we’re doing all the right things? The human body wants to preserve itself. It fights weight loss by adapting the metabolism to accommodate decreased calorie intake and/or increased calorie output. The body's new plan of attack is multi-pronged: increase calorie intake by making you hungrier (so you eat more), use less energy to accomplish physical activity (so you burn fewer calories) and hold on to stored fat (so it can use it for energy).
I think plateaus often happen because we're in a rut. So even if you believe you're doing all the right things in terms of diet, exercise, and mental or emotional effort - try changing them. If nothing else, it will prevent boredom and help you feel that you're taking positive action instead of being a victim of fate.
Here are some things you can try to shake up your routine.
Change the intensity, duration, frequency and type of exercise you're doing, so your body doesn't become too efficient at burning calories when you work out.
Don't neglect strength training - muscle burns far more calories than fat does.
Don't over-train - take one day off exercise a week.
Plan all your meals (the "how much" as well as the "what").
Weigh and measure your food before you put it on your plate.
Log your food intake - you might be surprised to see what and how much you're really eating.
Try calorie shifting: vary your calories - eat 1200 one day, 900 the next, and so on, to keep your body guessing.
Eat 3 small meals and 3 healthy snacks a day instead of 3 meals a day.
Increase your water intake.
Decrease your sodium intake.
Don't weigh yourself every day - switch to once a week.
Don't skip breakfast.
By the way, if you weigh yourself every day and think that no weight loss for three days running is a plateau, you're going to have a long journey ahead of you. Get off that scale, now!
I have one more suggestion that you probably won't want to hear: CULTIVATE PATIENCE. No, it's not one of my virtues, either. Give it a try anyway.
