I've picked one objective to focus on for a few weeks. After a while, it just ebcomes habit. I like to pair it with a great reward. First, I gave myself a great fitness reward every week that I hit 210 fitness minutes (a new workout shirt or shorts, a subscription to a fitness magazine). After several weeks, fitness became a fun habit and something I would never miss. Next, I aimed for 8 servings of fruits and veggies a day, which went well. Now, I'm finally trying to hit my calorie range.
You can do this by: 1)recalculating your calorie needs and making sure you're eating enough 2) Start a strength training routine. Muscle burns 70% more calories than fat, so building muscles will torch serious calories 3)Increase your cardio intensity and/or time.
Based on SparkPeople's BMR article, (which needs pen & paper to tabulate), I created an online calculator you can use.
If staying in calorie range is the most difficult part of your journey, try setting a lower weight-loss rate so you will have a higher calorie range. Adjusting your goal from 2 lb/week to 1 lb/week makes is so you can eat approximately 500 more calories per day!
