This follow-up session with Allison is a really special episode. When we first spoke a few weeks ago I told her she was practically starving herself. I gave her some advice on what to change to see some improvements, but what I didn't know at the time was that Allison has MS. I only found out a few weeks later when I checked in on her and she told me she was in the middle of a relapse or a MS Hug.

I was really nervous about our catch-up. She had recovered from the relapse, but I know how hard it is to make diet changes with the usual stressors we all have to cope with. But doing it while coping with MS relapses and the side effects of the condition?

But what Allison told me blew me away. Within a few days of making the changes I'd given her, she felt immediately better. Then the MS Hug hit and she was confined to bed, relying on her family to care for her until she recovered. But as soon as she could, she got back onto it. Her new way of eating had made such a profound difference, she was determined to keep going.

Now she's got her hunger and cravings under control and has even found the energy to go walking everyday for 45 minutes. These are the things that change your life. Don't miss this episode - it will change your mindset about the power of what you eat.
