Fitness suggestions?

May be do a different type of cardio and use different weight training exercises. My husband got stuck on his weight loss process but found out that he needs to change it up after a while. Hope that helps.

what's a good snack before bed build muscle and six pack abs?

Weight loss slows down because the more you lose, the smaller deficit you can achieve. It's also desirable and healthy to lose the last pounds more slowly than the early pounds. I lost 150 over 2.5 years. I never plateaued and lost every month. Each 6 month loss was a bit less than the previous 6 month period. I never saw that as a problem. By the time I got to goal, I was losing so slowly I just kind of eased into maintenance.
