Losing belly fat in one week seems like a dream. Unfortunately, that's all it is. Spot reducing does little more than tone muscles that will stay hidden beneath the fat. It's better to use that week to begin an overall fitness and reducing program. Start by eliminating sugar, caffeine, unhealthy fat and junk food. Eat balanced amounts of protein, carbs, fruits and veggies, emphasizing foods such as walnuts, apples, avocados and leafy greens that are rich in nutrients, fiber and healthy fats.
Kick Up The Cardio
If you're sedentary, get moving. Aim for 30 minutes per day, at least five days a week, of moderate cardio activities such as walking, swimming, dancing or bicycling. If you're already active, try to double the time of these activities at least three days a week, or intensify your workout by adding sprints, hill climbs or wearing ankle or wrist weights.
Do The Plank
Developing muscle helps improve posture for a leaner look, and it increases your metabolism to burn more calories. An all-over strengthening exercise that targets the core muscles is the plank. Support yourself on elbows and knees, then work your feet backwards until you are supported on forearms and the balls of your feet. Breathe evenly as you straighten and tighten your muscles so your body looks like a plank held off the ground. Aim for 45 seconds in this position. Do this and other strengthening exercises at least two days a week.
