Moving your body helps with energy, mood and sleep, with or without keto. Here is how the two fit together.
The adjustment period
When you first cut carbs, workouts can feel harder for a week or two. Strength and endurance often dip as your body adapts to using more fat. Many people find it improves with time, but experiences differ, and there is no guarantee.
Practical tips
- Ease in. Walks, light strength work and easy cardio are great in the first weeks.
- Stay hydrated and salted. Sweating loses fluid and electrolytes, which matter more on low carb.
- Eat enough protein to support muscle.
- Eat enough, period. Under-fueling plus hard training is a recipe for fatigue.
- Prioritize sleep. Recovery is when you get stronger.
Timing meals
Some people eat a satisfying low-carb meal a few hours before training; others train fasted. Experiment gently and see what feels right.
High-intensity training
Very high-intensity or long endurance efforts rely heavily on carbohydrate. Competitive athletes sometimes adjust carb timing and should work with a sports dietitian.
Safety first
Please check with your doctor before combining a major diet change with a new or intense exercise program, especially if you have a health condition or take medication. Stop if you feel faint, dizzy or unwell.
