In what is perhaps the biggest buzzkill of all time, sex doesn’t quite count as cardio or burn a significant amount of calories: Women burn about 3.6 per minute. "It’s still a good idea," Dr. Seltzer says, citing the activity’s other benefits, like increasing the output of the neurotransmitters serotonin and dopamine, which naturally reduce food cravings.
The easier it is to seamlessly fit a diet plan into your life without major lifestyle changes, the better. After all, by focusing on holistic long-term results rather than trendy short-term solutions, sustainability becomes the number one enemy of the feared “yo-yo” effect. During our investigative process, we asked ourselves: What makes a diet plan sustainable? After long hours of research, we decided that the following factors can determine a plan’s sustainability, and thus its odds of success: 

To prep his patients for success, Dr. Seltzer tells them to plan around a large evening meal by eating a lighter breakfast and lunch—NBD since most people who eat a meal before bed tend to wake up feeling relatively full, he says. Research suggests balanced bedtime meals may also promote steady next-day blood sugar levels, which also helps with appetite regulation.

"Oolong, or 'black dragon,' is a kind of Chinese tea that's packed with catechins, nutrients that help promote weight loss by boosting your body's ability to metabolize fat. A study in the Chinese Journal of Integrative Medicine found that participants who regularly sipped oolong tea lost a pound a week, without doing anything else to change their diet or exercise habits." — Kelly Choi, author of The 7-Day Flat-Belly Tea Cleanse
Everyone’s body is different when it comes to digesting some gas-forming foods, but there are a few you should be wary of: It’s best to avoid beans and cruciferous veggies (think cabbage, Brussels sprouts, cauliflower, and broccoli) for a couple of days if you want to look slimmer. Choose lean proteins like chicken and fish or, if you’re vegetarian, go for small amounts of nuts and seeds for protein. Pair with non-gassy vegetables like asparagus, spinach, and cucumber to help prevent bloat.
The "all meat all the time" low-carb approach or strict veganism can be great options for people who thrive on clear diet rules (and those two are actually the most popular diets out there) but these extremes are not for everyone. If you prefer more of a moderate approach, the Flexitarian diet is the clear winner. The "flexible vegetarian" mindset allows you a healthy balance of plant-based foods, responsibly sourced meats, and quality fats. The best part? It's not super restrictive, so you have plenty of nutritious food options. (Start here: How to Adopt a Flexitarian Diet)
DASH stands for "dietary approach to stop hypertension" and was created by the National Institutes of Health (NIH) as a way to help reverse national trends of obesity and heart disease. Scientists combed through decades of research to come up with an expert-backed list of diet tips, along with a prescription for exercise. And it worked: The DASH diet has topped nearly every diet list for nearly a decade. Doctors particularly recommend it for people looking to lower high blood pressure, reverse diabetes, and lower their risk of heart disease. (Here's the basic list of DASH diet-approved foods.)
Make room in your freezer for our best overall diet plan. Why is Diet-to-Go our “best overall”? Because it meets (and in some occasions surpasses) our selection criteria: it is sustainable over long periods of time, relatively easy to follow, less pricey than similar plans, healthy and nutritionally sound, very flexible, and takes away any meal planning hassles by delivering all your daily meals right to your door. And while other diet plans may exceed Diet-to-Go in certain criteria, our pick is certainly the most complete and “all-inclusive” of them all.
It seems counterintuitive to drink lots of water when you’re looking to lose weight fast—especially water weight—but staying hydrated is one of the most important steps you can take to lose weight. People often mistake thirst for hunger, so staying hydrated allows you to be more in touch with the times when you are actually hungry, rather than just thirsty. Plus, a lot of good things happen to your body when you drink enough fluids.
If you’ve been eating fast food for years, get real about your approach: You’re probably not going to stick to an organic, gluten-free, paleo overhaul for very long. "You want to change as little as possible to create calorie deficit," says Dr. Seltzer, who insists the best way to support sustainable weight loss is to incorporate small changes into existing habits. So instead of giving up your daily BLT bagels in favor of an egg-white wrap, try ordering your sandwich on a lighter English muffin. Or say you eat a snack bar every afternoon: Swap your 300-calorie bar for a 150-calorie alternative. "Your brain will feel the same way about it, so you won’t feel deprived," he says.
