The TKD (Targeted Ketogenic Diet) protocol is a specialist and advanced approach for ketogenic athletes that will allow one to lift harder and heavier, do some extra reps, as well as promote muscle growth while minimizing fat gain (as long as diet and training are on par, of course).
The Targeted Ketogenic Diet (TKD) is nothing more than the standard ketogenic diet (SKD) with carbohydrates consumed at specific times around exercise. This means that extra carbohydrates are consumed on days when exercise is performed.
If fat loss is the goal, the number of calories consumed as carbohydrates should be subtracted from total calories, meaning that less dietary fat is consumed on those days. The TKD is a compromise approach between the SKD and the CKD.
The TKD will allow individuals on a ketogenic diet to perform high intensity activity (or aerobic exercise for long periods of time) without having to interrupt ketosis for long periods of time.

Weight training is not generally limited by the availability of blood glucose. Studies giving carbs prior to resistance training have not found an increase in performance. However, almost without exception, individuals on a SKD who consume pre-workout carbs report improved strength and endurance and an ability to maintain a higher intensity of training during their workout.
Anyone following a ketogenic diet who wishes to perform high intensity training can benefit from the TKD approach.
Very little research has examined the effects of a ketogenic diet on weight training performance and it is difficult to determine exactly why performance is improved with preworkout carbs. It may be that raising blood glucose to normal levels, which only requires a minimal 5 grams of carbohydrate, allows better muscle fiber recruitment during training or prevent fatigue. Ultimately, the reason why carbohydrates improve performance is less critical than the fact that they do.
The major goal with pre-workout carbs is not necessarily to improve performance, although that is a nice benefit. Primarily, the goal is to provide enough carbohydrate to promote post-workout glycogen synthesis without interrupting ketosis for very long. That is, the carbohydrate taken prior to one workout is really an attempt to ‘set up’ the body for better performance at the next workout by maintaining glycogen levels.
Although experimentation is encouraged, most individuals find that 25-50 grams of carbohydrates taken twenty to thirty minutes before a workout enhance performance.
The type of carbohydrate consumed pre-workout is not critical and individuals are encouraged to experiment with different types of carbs. Most seem to prefer easily digestible carbohydrates, either liquids or high Glycemic Index (GI) candies as to have them absorb fast in the body and also to avoid problems with stomach upset during training.
Research suggests that carbohydrates consumed before or after exercise should not negatively affect ketosis. However, some individuals find that they drop out of ketosis transiently due to the ingestion of pre-workout carbohydrates. After workout, there will be a short period where insulin is elevated and free fatty acid availability for ketone production is decreased. However, as blood glucose is pushed into the muscles, insulin should drop again allowing ketogenesis to resume within several hours.
Post-workout carbohydrates might be expected to have a greater effect on ketosis, in that insulin levels will most likely be higher than are seen with pre-workout carbohydrates. For this reason, individuals may want to experiment with pre-workout carbohydrates first, only adding postworkout carbohydrates if necessary.
The formula for the Ketogains Version of TKD: “KETOGAINS COFFEE”
Take this formula between 15-30 minutes before strength training:
- 14 to 28 g MCT Oil or Coconut Oil
- 7 to 14g Dextrose or Glucose or Maltodextrin (High glycemic, easily and fast absorbing carbohydrates)
- 200mg Caffeine (or strong, black coffee)
Preferably, avoid fat for 1 to 2 hours after training:
Fat should generally be avoided in a post-workout meal. First and foremost, dietary fat will slow digestion of protein and/or carbohydrate. Second, the consumption of dietary fat when insulin levels are high may cause fat storage after training (1)

Now, about avoiding fat post training, Alan Aragon says to no t worry about it in this post.
So, the jury still stands: more evidence is needed. It could be beneficial to avoid fat ingestion post workout if you feel inclined to and as a “safety” measure if your main goal is to lose body fat.
- You can use pure MCT Oil instead of Coconut Oil, be aware that MCT Oil is about 50% more potent and may cause stomach upset on some people.
- For carbohydrates, preferably use Karo “Lite” Syrup – the zero high fructose version – or Dextrose Tablets. Start with 7g, and only after careful experimentation you may increase a little. Preferably do not exceed 30g.
- No post workout carbs are needed, its overkill.
- Another way to get energy is with KetoCaNa, which is exogenous beta-hydroxybutrate (BHB) in powdered sodium and calcium salt form.
- Coffee just adds caffeine which helps with energy and is a good delivery method, but you may substitute it with tea ior take all the ingredients separately if you prefer to.
- You can use some additional pre-workouts, just review ingredients and carb content.
- Creatine timing is inconsequential, just take your 2.5 to 5g on a daily basis (even if you do not work out that day).
- You will still meet your suggested ketogenic macros: 0.8-1.0g protein per lean lb; less than 30g carbs (PLUS your TKD carbs); and the rest of your calories from fat, according to your goals.
- Preferably avoid fruits and high fructose in general for the sake of TKD. Why? Because fructose just refills liver glycogen, and does not really help toward muscle glycogen replenishment.
