TKD ketogenic diet: Optimize performance with strategic carbohydrates

If you are following a ketogenic diet but notice that your performance in intense sessions is declining, the TKD ketogenic diet (Targeted Ketogenic Diet), or targeted ketogenic diet, may be the solution you need.

Imagine being able to take advantage of the metabolic benefits of ketosis most of the time, but with a strategic carbohydrate window that allows you to perform when training demands it. In this article, we explain what TKD is, how to manage peri-workout carbohydrates and when it makes sense to try it.

In this other article, we clear up whether is the ketogenic diet for athletes, and which variants may be most suitable. 

What is the TKD ketogenic diet?

The TKD ketogenic diet is a variant of traditional ketosis which adds a controlled amount of carbohydrates right around training: before and/or after. The idea is to keep the body mostly in ketosis while providing available glucose at times of peak energy demand to sustain intense efforts or sprints without a drop in performance due to lack of glycogen.

In practice, TKD keeps the focus on fats and proteins for most of the day. This way, carbohydrates do not disappear from the diet but are concentrated in a peri-workout “window” to optimize performance and recovery.

Benefits of the TKD ketogenic diet for athletes

Adopting a TKD ketogenic diet can offer several benefits for those who combine strength training or high-intensity sessions with the goal of maintaining a ketogenic metabolic state. These include:

• Better performance in explosive or intermittent efforts, by having accessible glycogen in the muscles during training.
  
• Optimized recovery, since consuming carbohydrates after exercise facilitates glycogen resynthesis and anabolic signaling.
  
• Lower risk of overtraining by being able to maintain intensity without burning exclusively fat when the pace increases.
  
• Metabolic flexibility, while preserving the benefits of ketosis (appetite control, energy stability outside training) and, at the same time, improving short-term performance.

What happens to carbohydrates in the TKD?

In the TKD ketogenic diet, carbohydrates are used strategically. Since it has been shown that when consumed before exercise, they tend to be rapidly taken up by active muscle thanks to the increase in glucose transporters; after exertion, insulin sensitivity is high and the muscle “draws in” carbohydrates, promoting glycogen replenishment.

Are you worried about coming out of ketosis? Then don’t let that happen. Since the amounts remain moderate (usually between 25–50 g before the workout and a similar amount during recovery), ketosis is interrupted temporarily and usually restored within a few hours. But keep in mind that every body reacts differently.

How to structure a TKD: pre-, during, and post-workout

The total amount of carbohydrates added to the keto plan must fit your calorie budget and your goal (fat loss, maintenance, or gain).

• Pre-workout (30–45 min beforehand). 25–50 g of rapidly absorbed carbohydrates (e.g., dextrose or glucose) to provide immediate energy.
  
• During the workout. It is normally not necessary except for long workouts (>90 min) or sessions with a demand >80% VO₂max; in those cases, small doses of carbohydrates may maintain performance.
• Post-workout. 20–30 g of carbohydrates together with protein may support recovery and protein synthesis.

And if you are coming from strict ketosis, try small amounts of carbohydrates and adjust them according to how you feel during your workouts. 

When should you consider the TKD ketogenic diet?

Consider the TKD ketogenic diet in case you notice a loss of intensity during high-demand workouts; you are a strength athlete or participate in intermittent sports; or if you want to maintain ketosis most of the time but need “glucose spikes” to perform; or if you are looking for an intermediate strategy between strict ketosis and a high-carbohydrate diet.
