After people lose a good bit of weight, they no longer need the old calories they were taking in. So, to effectively lose weight,they need to reduce their caloric intake.Let's say you were taking in 1700 a day.....You lose 35 pounds.. You'll need a new caloric deficit because you would be taking in too many calories resulting in a plateau. Instead of 1700,try reducing to 1500 or 1400. Hope this helps.
