Lose weight;
1. Determine your adjusted "sedentry" RMR (not BMR) -
here. This is (roughly) how many kcal you need to maintain your current body weight.
2. Deduct 250-500 kcal from that figure.
3. Set out a rough meal plan for yourself that meets the figure in #2. Eat clean, healthy calories, no
saturated or trans fat (other fats are good eg Omega3), no refine sugars, no alcohol, reduce starchy carbohydrates, eat wholemeal/wholegrain everything if you do eat grains. Eat lean meats - chicken, turkey, seafood. Check packets, make sure you know what you're eating, it's important you know how many calories you're eating and where those calories are coming from. Do
not get stuck into calorie counting, you just want a rough idea. If you can eat 6 even meals a day, this will ensure your metabolism is stimulated regularly and you will burn more calories throughout the day. Like a good Scout
be prepared, have healthy snacks at hand, at home and the office (or school or whatever). Holland and Barret is a good place to find these.
4. Exercise (any form) for a minimum of 30 min a day, the more calories your burn (ie the greater the effort) the more weight you will lose. Forget the "fat burning zone" - work hard, burn calories, achieve results.
5. All good trainers would recommend some Resistance training as well as cardio to build muscle. Muscle burns fat at rest and more fat while exercising, the more you have the more your burn. Also when you get to your goal weight, your diet may return to a more "normal" state (eg more alcohol, more eating out, less hard training) this muscle will help you retain your new found (and loved) physique.
6. Stay
OFF the scales. Use your clothes and mirrors to judge your weight loss, scales only serve to demoralise. Set a weigh in date (ie 3 months into the future) and take body measurements before you start weight loss, take photos as well so you can gloat to all your friends later with your before and after shots.
The good news, the fatter you are the quicker you lose weight, your target will get tougher towards the end as your body becomes accustomed to the exercise and more efficient with doing more with less (calories). Switch it up, change your routine run, sprints, swim, skip, play sport - make your body keep guessing and using different muscles.
3500 kcal = 1 lb (.4kg) of fat, you want to aim for that loss each week for a healthy weight loss. The aim is not to be in a calorie deficit of more than 500 kcal, because the body thinks it's being starved and slows your metabolism down to conserve more calories - which in turn mean you burn fewer. My own experience seems to differ, but that's what dietitians recommend - it differs probably because while my deficit is greater than 500 kcal it's greater through exercise, not calories consumed. I ride 120-150 km per week, weights 2-3 x week, run 2-3 x week and swim 3 x week.
