The talk show host is back in shape, and it’s all because she regained control of her eating habits.

On Wednesday’s episode of The Tyra Show, the model reveals a longtime struggle she has with stomachaches:

I would get major attacks. I would be in bed for days, it was so painful.

The 35-year-old thanks her nutritionist for helping her re-evaluate her eating habits by keeping a food diary:

I switched up my unhealthy eating habits for healthier eating habits, and I haven’t had a tummy attack since December ’08.

Since that whole swimsuit incident back in 2007 (come on, you know what I’m talking about), she’s lost almost 30 lbs! The girl still has curves, though:

I feel good about my curves and my imperfections – my booty, my boobs, my thighs – I embrace it all. Now I really can say … kiss my fat – and still fat – ass.

Such an achievement. Woohoo, Tyra!
