I totally agree with Mugsy. We had much success when we switched foods and started Honey and Lilly on a weight control formula. We used Iams Weight Control, in the blue bag, for six months. Now they are eating California Natural Low Calorie, Lamb and Rice. They are maintaining their weight beautifully.

You can get low cal treats as well, plus supplement with fresh vegetables, carrots and green beans. Some people use cottage cheese (lowfat of course) and plain yogurt successfully as well.

Good luck. It will work. But I agree with the others. Have a thyroid test run first, just to rule out medical issues before starting the diet.
