About a year ago I was 72-73kg so I started to walk for exercise. I got my weight down to about 67-68kg which I attributed to the walking and eating a little better. Recently I ve moved to a new house so I ve been busy and stopped walking frequently. I ve also been eating more as I rarely are breakfast before but now I eat it everyday. However, even with the lack of exercise and increase in eating, my weight has been steadily decreasing for more than a week. It has now fallen to 64.9kg and I m beginning to worry. What s going on? I ve recently had to move my belts one notch down as my pants are starting to feel loose. I m starting to think the initial weight loss was also more of this problem and not due to exercising. Should I be as worried as I am? For reference I m 34 years old and 181cm. I don t smoke or drink. Also I feel full after eating just a small meal and I don t get very hungry at all through the day as long as I eat one thing.
