I've read an article by Christian Thib. about fat loss and how it come in spurts. I started at 210lbs and went down to 155lbs (skinny fat) and now back up to 180lbs. When losing weight, initially it seemed linear but seemed harder after I lost the initial weight. Then the weight lost came in spurts. During this spurts I always seemed to get sick. I finally decided to start gaining weight. Initialy I gained the first 10lbs linearly but the last 15lbs seemed to come all at once after about 3-4months and while I was sick. Has anyone noticed that their spurts seemed to happen when they were sick? Maybe its a sign from my body to tell me to rest.
