Get yourself a set of reliable scales and weigh yourself first thing in the morning.. preferrably after you’ve been to the toilet, before you have breakfast. Weighing yourself throughout the day just shows you how much you’ve eaten and how much water you’ve taken etc. Weighing in the morning is the best way to see how much your weight changes each day, before you start eating, drinking and going about your normal daily activities. It’s a good idea to write it down in a table. I do this and I find it gives me a good indication of how my weight loss is going. If you take it at different times of the day, you’ll get an unrealistic view of your weight loss progress so first thing in the morning is best.
