With just seven days, you also don't have time to put together a total weight loss workout program. And if you try to do hardcore fat-burning workouts without any previous experience, you could easily injure yourself. So if you want to lose weight in a week, increase your steps per day to burn more calories. Exercise can also help reduce stress and improve your sleep, both of which may also contribute to weight loss.
You can add more veggies to your diet, enjoy your "cheat" foods, and cut back on the calories you’re eating, all at the same time. When Penn State researchers added pureed cauliflower and zucchini to mac and cheese, people seemed to like the dish just as much. But they ate 200 to 350 fewer calories. Those healthy vegetables added low-cal bulk to the tasty dish.
All meals are important, but breakfast is what helps you start your day on the right track. The best, heartiest breakfasts are ones that will fill you up, keep you satisfied, and stave off cravings later in the day. Aim to eat anywhere between 400 and 500 calories for your morning meal, and make sure you're including a source of lean protein plus filling fat (e.g., eggs, unsweetened Greek yogurt, nuts, or nut butters) and fiber (veggies, fruit, or 100% whole grains). Starting your day with a blood sugar-stabilizing blend of nutrients will help you slim down without sacrifice.
Stephen Colbert may be on to something. UCLA Center for Human Nutrition researchers divided study participants into two groups, each of which were fed a nearly identical low-cal diet for 12-weeks. The only difference between the groups was what they were given to eat as an afternoon snack. One group ate 220-calories of pretzels while the other group munched on 240-calories worth of pistachios. Just four weeks into the study, the pistachio group had reduced their BMI by a point, while the pretzel-eating group stayed the same, and their cholesterol and triglyceride levels showed improvements as well.
