Developed by Joel Fuhrman, MD, a nutrition expert and researcher, this book-based diet plan is all about nutrient density: Eat the foods that have the most nutrients per serving (and per calorie), and you will be healthier overall and lose weight. Dr. Fuhrman’s 10-in-20 Plan claims you’ll lose ten pounds in 20 days. This produce-focused program has you eliminate all processed foods, dairy, sweeteners, and oils, which some people complain is too restrictive. There’s also an online component that offers membership with a community of nutritarians. Don’t miss these other 50 ways to lose weight without a lick of exercise.

Cortisone as an oral drug is another common culprit (e.g. Prednisolone). Cortisone often causes weight gain in the long run, especially at higher doses (e.g. more than 5 mg Prednisolone per day). Unfortunately, cortisone is often an essential medication for those who are prescribed it, but the dose should be adjusted frequently so you don’t take more than you need. Asthma inhalers and other local cortisone treatments, like creams or nose sprays, hardly affect weight.

Other diabetes medications. Insulin-releasing tablets (e.g. sulphonylureas) often lead to weight gain. These include: Minodiab, Euglucon, Daonil, and Glibenclamide. Tablets like Avandia, Actos, Starlix and NovoNorm also encourage weight gain. But not Metformin. The newer drugs Victoza and Byetta (injectable) often lead to weight loss, but possible long-term side effects are still unknown. More on diabetes

Liquid calories could sabotage weight loss success. Soda is an obvious culprit, but fruit juice, energy drinks, alcohol, and other sugary beverages could all also add to weight gain or obesity, according to research. “Sometimes a bottle of iced tea or juice has 2.5 servings,” says Lisa Lillien, founder of HungryGirl.com and author of the book The Hungry Girl Diet. “Read labels and you’ll see it’s just not worth it.” Dr. Bazilian adds that sodas and other fruit “drinks” don’t satisfy hunger—meaning you may eat equal or more in food calories too. These are the quick weight loss tips nutrition pros swear by.
Open up a big bag of baby carrots and dip them into your freshly made no-oil-added, no-salt-added hummus. Simply whip up in your food processor a can of no-salt-added chickpeas/garbanzo beans, fresh tomatoes, lemon juice, garlic, a jalapeno pepper (if you like your hummus hot and spicy), and fresh herbs like cilantro and dill. Add a little water, if necessary, until the desired consistency is achieved.
Directions: Rinse 1 cup of quinoa in cold water. In a medium saucepan, combine quinoa with 1 tablespoon curry powder and 1 teaspoon turmeric. Add 2 cups low-sodium chicken broth and bring to a boil. Cover and simmer until the water is absorbed—about 15 minutes. Stir in 1 cup shredded carrots and 1 cup cubed firm tofu. Makes about 4 one-cup servings. Refrigerate remaining servings for an easy, healthy snack or meal later in the week.
The scale is not necessarily your friend. You may want to lose fat – but the scale measures muscles, bone and internal organs as well. Gaining muscle is a good thing. Thus weight or BMI are imperfect ways to measure your progress. This is especially true if you’re just coming off a long period of semi-starvation (calorie counting), as your body may want to restore lost muscles etc. Starting weight training and gaining muscle can also hide your fat loss.
Once you’re done with your meal prep, make sure you let your meals cool down before transferring them to airtight containers and storing them in the fridge, but make sure you don’t keep your food in room temperature for more than two hours. If you are using meal prep containers and have stored your cooked meal prep well, it can last in the fridge for up to 7 days.  Some foods will keep longer than others, which is something to consider when prepping 7 days at a time.
A 2012 study also showed that people on a low-carb diet burned 300 more calories a day – while resting! According to one of the Harvard professors behind the study this advantage “would equal the number of calories typically burned in an hour of moderate-intensity physical activity”. Imagine that: an entire bonus hour of exercise every day, without actually exercising. A later, even larger and more carefully conducted study confirmed the effect, with different groups of people on low-carb diets burning an average of between 200 and almost 500 extra calories per day.
Even if you do meet your goal, it's nearly impossible to keep off the weight over the long term: "The amount of restriction required [to maintain that number] will make you so hungry that you’ll eat everything in sight—it’s survival instinct," Dr. Seltzer says. And since calorie restriction gradually slows your metabolism, your body will be less prepared to burn the foods you binge on, he adds. That could mean gaining more pounds than you lost in the first place.

Topping foods with heavy sauces or condiments could add extra calories and often little nutritional value. For example, ketchup often has a high amount of sugar. According to Monica Auslander, a registered dietitian and founder of Essence Nutrition, one teaspoon of ketchup is equal to eating a sugar packet. “It’s deceiving because it has no fat, so people think they can enjoy freely,” she says. “Unfortunately, we now know that sugar is far more insidious than fat.” Fortunately, there are healthier lower-calorie options such as pesto, hummus, and DIY recipes. These are the condiments that are bad for your health.


It could be beneficial for your health and your weight loss goals to drink more water and less alcohol. Dr. Bazilian says that alcohol doesn’t have to necessarily be avoided altogether. but you should think if and where alcohol fits in the context of your overall health goals. “Aside from calories, alcohol doesn’t offer much by way of nutrition, so it’s at minimum an important decision to have going into any weight-loss program for yourself whether, how often, what type and how much may or may not fit in your timeline and goals,” she says. Alcohol also reduces inhibitions sometimes making it more challenging to make healthy eating choices, according to Dr. Bazilian. And alcohol may negatively impact sleep which plays a role in healthy metabolism, she adds. 

Fiola Sowemimo, MD, board-certified in internal and bariatric medicine, says that the quality and quantity of food you eat is only half of the weight loss equation. “Regardless of which diet you choose, when you eat is important too,” Dr. Sowemimo says. Starving during the day and ignoring hunger could lead to bingeing later, she says. Plus, Wendy Bazilian, DrPH, RD, adds that the peaks and valleys of hunger throughout the day could make it more difficult to manage cravings. Eating regular meals at regular times could actually help normalize your metabolism, according to Dr. Bazilian.  


Keeping fruits and vegetables in your line of sight could encourage you to eat more of them—rather than other high-calorie snack options. On the other hand, research shows that when unhealthy options are in full view, hunger and cravings may increase. One study published in Health Education & Behavior specifically found that when high-calorie foods are more visible at home, the residents are more likely to weight more, compared to people who only keep a bowl of fruit out. These are the superfoods that could help you lose weight.
A calorie isn’t always a calorie. Eating 100 calories of high fructose corn syrup, for example, can have a different effect on your body than eating 100 calories of broccoli. The trick for sustained weight loss is to ditch the foods that are packed with calories but don’t make you feel full (like candy) and replace them with foods that fill you up without being loaded with calories (like vegetables).
Before you start the meal plan, make a pot of the Veggie Soup. Make 2 servings of Overnight Oats, so they can soak in the fridge. It’s also super helpful to prep your veggie snacks—make 4 bags filled with baby carrots and sugar snap peas, and 3 bags filled with broccoli and cauliflower, for alternate days. And if you really want to get ahead, you could also grill the chicken breasts and cook the quinoa and brown rice in advance.
