To shrink your waist, improve your diet, change your eating habits, exercise daily and adjust your sleep schedule if necessary. Many people find that counting calories is helpful. If you burn more calories than you consume, you lose weight.
Avoid eating dairy products or meats that contain fat. Try not to eat starches or sugars, and make sure to eat food with plenty of fiber. Lean meats and eggs are good low-fat protein options. Try to eat fruits and vegetables with every meal, and drink plenty of water.
Reconsider your approach to eating. Try to schedule three healthy meals at the same time each day. Always eat at the table, and avoid snacking out of boredom. Start a food journal, and keep track of everything that you eat. This allows you to monitor your eating habits, and it helps to keep you accountable. Poor sleep habits can also cause weight gain, so try to get around seven hours of sleep nightly. Try to go to bed and wake up at the same time consistently.
It's important that you burn more calories than you eat, so exercise for at least 30 minutes every day. Try to do exercises that make you sweat. If you don't exercise often, be sure to start off slow. Always warm up before you perform rigorous exercises, and speak to a physician before exercising if you have been inactive for a long period.
