Diet Plan FAQs
Although there’s no one-size-fits all weight loss plan, ultimately, a good diet plan is one that enables you to reach your weight loss goals in a sustainable way, without depriving you of the nutrients your body needs.
A good diet plan, for instance, won’t eliminate entire food groups or macronutrients (think protein, fats and carbs), and won’t cut so many calories that you feel like you’re constantly at risk of either passing out or plunging head-first into the pantry in a “moment of weakness.” Instead, a good diet plan will include a balance of macronutrients, and encourage a variety of foods to ensure that all of your micronutrient (a fancy word for vitamins and minerals) are met. A diet rich in vegetables and fruits, lean proteins, healthy fats and complex, fiber-rich carbs can deliver all the nutrients you need without piling on the pounds. And by keeping processed foods that are high in sodium, sugar, fat and calories to a minimum, a good diet plan will be an investment in your health as much as it is a means to weight loss.
Of course, there are other considerations when choosing a diet plan. Price, convenience, meal delivery, trial periods, cancellation policies—these are all factors you should think about. It’s worth putting some thought into which of these aspects matter most to you before committing to a plan.
Once you’ve decided what’s most important to you, take a look at our list of top rated diet plans to choose a good diet plan for you. We’ve included meal delivery diet plans for those who like the convenience of having prepared meals and snacks delivered to their door, and DIY diet plans like Noom, which provide guidance for preparing your own meals. We deliberately chose a variety because ultimately, choosing a good diet plan is personal—and the best diet plan will always be the one you will stick to.
It’s possible to lose 10 pounds in one week if your starting weight is high enough and you deprive yourself enough. But the research suggests that people who lose weight gradually and steadily (about one to two pounds a week) are more successful at keeping it off. So, be wary of any weight loss plan that claims to be a “diet plan to lose weight fast,” and instead choose a meal plan for weight loss that promises steady results and teaches healthy habits to keep the weight off for good.
While exercise can certainly help speed up your weight loss, improve your muscle tone and even in some cases, give your metabolism a boost, studies suggest that physical activity alone isn’t as effective as following a weight loss diet. For optimal results (and health!) pair your diet plan with a mix of both cardio and resistance training.
