Deciding to go on a diet is easy, but sticking to a diet is not easy! So, when facing that challenge, it is important to know how to reach your weight-loss goal.
Of course, you have to decide you want to lose weight and be committed to doing so; then, you must stick to your guns and stay motivated or the goal will never be realized.
There is no magic bullet, but there are two important tips that can help you reach your weight-loss goal.
#1 – Take It a Week at a Time
You must break your ultimate goal into smaller chunks and have bench marks that will indicate you are moving in the right direction.
According to the Mayo Clinic, “Over the long term, it’s best to aim for losing 1 to 2 pounds (0.5 to 1 kilogram) a week.”
When you have a realistic weekly weight-loss target, you will be more confident in your efforts and you will know exactly what you are going to measure at the end of each week.
Your long-term goal may be 40 pounds, but take it “one week at a time” (1 to 2 pounds/week = 20 to 30 weeks)
In addition to choosing a healthy diet that fits your lifestyle and current health conditions, plus a solid commitment to stay with it, don’t forget to get plenty of rest and exercise. .
BUT . . .  the primary target should be the number of pounds you plan to lose each week. That target should be clear – and realistic. If it is, you should be able to stick to your weight loss program and enjoy success week after week, after week. AND, feel good in the process.
If you are not hitting your target, be willing to look closely at what you are doing, or not doing – and figure out why you are not reaching your weekly target.
Maybe the target you set was not sensible or reasonable; or, maybe you are putting too much pressure on yourself.
Honest introspection is a good way to see what you are really capable of doing and then, you can develop or choose a plan that is suitable for your unique lifestyle.
