Making weight for same day weigh ins

Have you ever cut weight before?  If not I wouldn't even worry about it just compete at what you walk around at.

All ibjjf tournaments are like this.

When I went to Brazil, I spent 4 weeks cutting weight to make the light division.  I didnt do any water/hydration cut the week before and I felt fine going in at at 160, just under.  I cut 10 lbs from my city walking wait.  It was easy to cut there because two weeks prior I was training jits 2 hours in the morning, resting at the beach in the afternoon then 2 hours at night.  No stress from work, and I could easily manage what I ate.

I was tempted to cut 8 lbs for the World Nogi, but there's no way I could dedicate myself to train twice a day, work 8 hours, etc.  So I'm going at the weight I walk at (170-172) and themax is 175.5 with gear.

If I only had to cut 2-5 lbs, I could do it simply with adjusting the diet and a little more cardio.

The whole reasoning for weighing in like this is to prevent people from cutting weight so much.  I prefer it this way IMO.

That's your best bet.  Weight cutting should be practiced and when its upwards of 8 to 10 pounds its better to give up a few pounds in the next division up as opposed to cut wrong and lose because you gassed.
