The keto diet is great for fat loss. By cutting carbs from your diet, you all-but force your body to use fat for fuel. But, while that’s good news for fat loss, it can be a problem if you are an avid exerciser. Under normal circumstances, your body likes to use glucose for energy during exercise. Without dietary carbs, there is no glucose, and that means some exercisers find that they don’t have as much energy as usual.
Exercisers who find themselves low in energy often turn to pre-workout supplements to give themselves a boost (from women, beginners, and even vegans). Unfortunately, many of these popular powders and drinks contain glucose and other sugars. Yes, they’ll provide you with energy, but they’ll also kick you out of fat-burning ketosis.
The good news is that supplement manufacturers have realized that keto dieters need pre-workout supplements too. These products will give you the energy you exercise as long or as hard as you want while preserving ketosis.
Here are five of the best Keto pre-workout supplements.

Going low-carb and keto can leave some dieters feeling flat, listless, and lacking energy for exercise. That’s a problem because exercise will enhance virtually every aspect of the ketogenic diet, from entering ketosis sooner to losing fat faster.
Pre-workout supplements can provide you with the mental and physical energy you need to power through your workouts. Some achieve this by increasing ketone levels with exogenous ketones or MCTs, while others boost your energy with caffeine, nitric acid, and other performance-enhancing ingredients.
If you are sensitive to the effects of caffeine or intend to exercise late in the afternoon or evening, high caffeine pre-workout supplements are not recommended. Too much caffeine at this time could keep you awake at night.
In contrast, pre-workouts that contain exogenous ketones and MCTs can help get you into ketosis after and may even help you beat the keto flu. On the downside, these ingredients can cause stomach upsets in some users.
Before you buy your keto-friendly pre-workout supplement, take a moment to check how it works so you can choose the right one for you. Armed with the best keto pre-workout, you can say goodbye to feeling too tired to exercise, and hello to more endurance, increased energy.
