When it comes to weight loss, everyone has an opinion. But are those thoughtful tips based on science, or mere personal opinion? These science-backed guidelines can help you manage weight safely — without losing your mind.
1. You Must Eat Your Meals
Your body runs on the fuel that comes from the foods you consume, so eating enough is vital. If it’s helpful, schedule your meals and snacks to stay on track. Keep in mind, what really counts at the end of the day is the total calories you eat over the course on an entire day, not any single meal.
If you tend to eat most of your calories before your bedtime, your digestion will probably still be in progress, and you may not have sufficient time to burn some of those calories by the time you go to bed. Try shifting to eating a larger breakfast or lunch and a smaller dinner, or eating dinner earlier.
Creating a moderate calorie deficit is key for weight loss, but skipping meals isn’t the most effective approach. Instead, focus on lower calorie, high volume foods like fruits and vegetables to help fill you up.
2. Carbohydrates Are Not the Enemy
Unfortunately, many companies have taken advantage of the low-carb craze by developing new products that trick you into thinking is a “better for you” option. However, many of these products are not healthier than their regular counterparts, and often come with more sugar and saturated fat.
Carbohydrates are an essential part of a balanced diet because they provide an abundance of key nutrients such as B vitamins, like folic acid, iron, fiber and many others. The key is to stick to the recommended portion sizes for your age and activity level and make at least half of your grains whole each day.

3. Fruit Is Essential
We’ve all heard it before: there’s too much sugar in fruit.
Yes, all fruit contains fructose, which is a carbohydrate. But these carbohydrates are needed for many important functions and are coupled with fiber, vitamins, minerals and antioxidants that support many bodily functionsnd help reduce the risk of chronic disease, including heart disease and cancer.
Although, the U.S. Dietary Guidelines for Americans recommend at least 2 servings of fruit per day, the Center for Disease Control and Prevention reports that only 12% of American adults are meeting the recommendation.
