This happened to me (sort of). I was eating right (portion-controlled) and exercising 6 times a week with lots of exericise. My weight has stayed the same for the last month approximately but people are telling me I look thinner. It is because I have gained quite a bit of muscle while losing fat. Check your body fat percentage at any gym. And whenever you gain weight again (which hopefully doesn't happen) check to see the percentage (should be lower
). Also, are you weighing yourself at the same time? If you're weighing yourself at night with jeans you will weigh substantially more than in the morning. Best time to weigh yourself is before breakfast and after you pee.
And a last reason :P, lol I come up with too many excuses, you could be getting your time of month soon. I generally retain water and crave sweets before hand. But yeah, for sure at least 3-4 pounds difference when I get my t.o.m. Some people up to 10. Hopefully I helped
