Harder time in the winter months?

If you think you may have SAD go see your doctor. A therapy lamp does help. It is sooo tempting to hibernate when the weather is cold and grey, but I find it helpful to try to get up and outside as many days as possible and as many have said find some daylight time to get out for a walk if possible. I usually go off the rails in November - so I have switched myself to maintenance. Even if I am at maintenance for 3 or 4 months it is better that giving up and gaining it all back.

Something that I love about my small town is that from Nov-March our high school offers indoor walking from 5-7pm on weekdays. You might want to see if your community has something similar or could start something if there's enough interest.

As far as eating goes, I love seasonal flavors (bring on the pumpkin, spices, soups, and stews!). I try to challenge myself on making my favorites a little healthier without sacrificing flavor, otherwise, what's the point? I would rather have one full fat muffin over five nonfat ones if they don't taste good. Sub ground turkey/chicken for beef in recipes, sub at least half of vegetable oil in baked goods for applesauce, etc. If you're on keto, try using almond flour, coconut flour, or carbquick instead of regular flour (or do half and half).
