Exercise II. Read the article, and choose the correct answer A, B, C or D for each question.
Simple Ways to Lose Weight on a Budget
Plan to Cook at Home Instead of buying costly prepared meals, which often tend to be high in calories, cook your own at home. Plan out your meals with high-fiber foods like beans and whole grains which will keep you full and are a cheaper, healthier alternative to rich proteins and more processed grains. Eat Less Eating less leads to weight loss, and cost savings, especially if you cut down on the right things. Start by cutting your portions of pricy meat and poultry. Double Up on Vegetables Vegetables are great for weight loss, as well as all-around health. They are low in calories and high in water and fiber - two things that keep you feeling full. Save cash by shopping for those that are in season. Frozen vegetables can be a great bargain, with just as much nutrition as fresh, since they are picked and frozen at their peak ripeness. Get Creative with Your Exercise Options You don’t need to shell out a monthly gym fee to get moving. Instead, find fun activities you enjoy for free. If you’re just getting started with a regular exercise routine, try your beginning with daily walks: start slowly and build up time and speed. Make Friends with Someone One of the most powerful resources you have for helping you lose weight is your social network. Find a friend who is also trying to lose weight and agree to help each other stay motivated. One study found that when friends participated in a group weight-loss programme together, they lost more weight than people who did the same programme on their own.
