Does Dieting Give You Insomnia?

We all know that the first few days of a diet can be the hardest.

Adjusting to eating a different way, resisting temptation and all the usual cravings. Overcoming those challenges can be difficult enough, but battling with insomnia one issue you might not be expecting.

Here at Exante, we look at the top reasons you might be struggling to sleep in the first few days of your diet.

Increased Water Intake

We all know the drill. Whatever your diet plan, the number one tip most people follow is to increase their water intake throughout the day. Water helps to flush toxins out of the body,  leaving you feeling fuller and reducing hunger pangs.

Upping your H20 levels can also mean increased visits to the loo, including at night and interrupted sleep can lead to you having difficulty dropping off again afterwards.

Solution: Avoid drinking a large quantity of water before bed, instead stagger your intake throughout the day, starting with a large glass as soon as you wake up.

Bedtime Hunger

If you are following our Total Solution plan, it could take up to 3 days before you enter a state of ketosis and hunger pangs reduce. Whilst it might be tempting to hit the hay to avoid the dreaded nighttime snacking, you may find that a rumbling tummy could prevent you from relaxing enough to nod off.

Solution: Plan your meals effectively so your last meal or meal replacement of the day is a couple of hours before bed. If following a plan which includes other foods, save a small snack for supper to ease the feeling of hunger.


If you have recently started exercising in an attempt to kick-start weight-loss you may be over-stimulating your body too close to bedtime. Many of us lead busy lives and hit the gym after work, which, with the typical working day now finishing at 6.30pm, could mean that your body is still pumped full of energy a few hours later.

Solution: As hard a sit might be to drag yourself out of bed, try to exercise as early in the day as possible. If night-time workouts are your only option, a relaxing routine like yoga or pilates is a good alternative to high intensity cardio.

Too Full

If you are saving your largest meal for dinnertime and not eating much in the day it can sit heavily on your stomach preventing you from a peaceful nights rest. Feelings of discomfort, bloating and indigestion are common with people who binge late in the day. Eating caffeine rich foods; such as coffee, chocolate and fizzy drinks can also over stimulate you causing insomnia.

Solution: Regardless of the plan you are following, small meals throughout the day are always better than banking the calories for a late-night blow out. Avoid caffeine after 4pm too.
