So you put five minutes of walking per day in your schedule for several days. If no time was spent, you need to go back to Step 1 and check your attitude. The same thing can be done with any of the solutions that seem likely to lose you weight, as long as the solution is defined in terms that you can measure. Walking can be measured in miles or minutes per day. Weight lifting can me measured in reps and how much you lift.
Weight loss is measured in pounds and inches.
Whatever you do come up with a measure that you know you can keep doing. If you stop reviewing your progress, then you probably will stop doing the solution. That usually means that your problem will not go away, or it will return. Keep reviewing how well you are doing your solutions. It's the secret of solving any problem.
