Some people can suffer from troublesome gastrointestinal tract issues due to the sudden absence of carbs in their diet (just 20-50 gms of carbs per day can be difficult). In simple words, you can get constipated. Starting your day with a difficult time in the washroom can cause you to become uncomfortable for the rest of the day.
How to resolve this?
Apart from the less carb intake, you could also be enduring such a problem because you aren’t consuming enough fibers, since most fruits are starchy and off-limits.
Not to worry, you can easily fix this. Start by drinking enough water to ensure your body has enough dehydration. Now as for fiber, go for less starchy vegetables like broccoli, cucumber, lettuce and cauliflowers. Since fruits contain a lot of sugar, you can read up the nutrient portions and go for low fiber fruits like avocados, peaches and watermelons. Flax or chia seeds, berries and nuts are good snack options as well. Consume these often and your mornings will become satisfactory again.
