Just a heads up. Tupperware made before 2010 is chock full of BPA.

To the OP: According to the success stoires, those first 50 pounds are pretty easy; it's the last 20 which are more difficult. If your husband has been Primal for 3-4 YEARS and made no progress at all, I don't think a tweak like IF-ing or gluten free beer is going to help. I agree with the recommendation of getting thoroughly tested by a specialist.
5'0" female, 44 years old. Started Primal October 31, 2011, at a skinny fat 111.5 lbs. Low weight: 99.5 lb on a fast. Gained back to 115(!) on SAD chocolate, potato chips, and stress. Currently keeping food tracker.
I (try to) follow by-the-book primal as advocated by Mark Sisson, except for whey powder and a bit of cream. I advocate a two-month strict adjustment for newbies. But everybody is different and should tweak Primal to their own needs.
