Hi S.,
I agree with the other mom, please be very careful with Protein Shakes. And also when you do find the right product for your husband, please consult with the Doctor or Nutritionist to look at the ingredients.
With that said, we have used Shakes(Meal Replacements) from a Company called USANA for the past 6 years. We have also helped many others lose weight as well as body builders keep the weight on. I have used Slimfast in the past due to competing in Pageants(dumb idea lol) so I know the difference.
This is not a diet! Diets do not work. When you view the video below you will understand why.
I use them in my daily life as well as my husband and my children and wouldn't dare put them in harms way. It was put together by a Doctor and is Low-Glycemic(very important) and is portable as well. My husband enjoys them so much he keeps it at work as well as a portable hand mixer. But it does come with a Shaker bottle.
Here are some documents you can look at:

Here is also a video to view the product and how it works:

Hope you find what works best. If you don't find anything feel free to email me, ____@____.com
We want your husband to live a long and healthy life.
God bless!
