A crazy program is doomed to fail as it's been proven many times. Why aren't you walking? Take your horse with you for company. It will do you both good. It's kinda nice having your horse walking and trotting alongside. Get out and explore the country side. You may not lose weight because you will become more fit and muscle is heavier than fat. A body building coach told me to never step on a scale but to measure 6 places on my body, record it then measure every week.
I've heard great things about the new Weight Watchers and I would recommend monitoring your carbs. I lost a solid 10lbs in a month and a half just counting carbs and keeping them below 70g of carbs a day. It's easy... For those of us that don't enjoy carbs. I love pasta, breads, and sweets... Sooo watching carbs is tough ;)
You can have anything you want, but in moderation. Carbs is a good way to start though, easier than counting carbs, imo.
