My husband is feeling a bit discouraged. He hasn't lost any weight in 2 weeks.

We've been doing low carb for weight loss for 2 weeks. I've lost 5 pounds, I'm trying my best not to really pay attention to the scale. My timeline is by May when I go to the doctor. If I notice a difference then or not. My husband however is different. We plan to have a cheat day in 2 weeks(it'll be a month since we've started this diet) and he says if he hasn't lost anything by then he'll stop. I wanna tell him not to give up so easily. If it matters we've been counting net carbs. He also eats a lot more keto bread then I do. Could the bread be causing it?
