![]() Novizio: digiuno intermittente 16-8 e approccio alla disciplinaCiao! L'IF è un approccio ottimo ma non ha senso re-inventare l'acqua calda...voglio dire che ti conviene partire seguendo lo schema di Berkhan e poi,se necessario, modificare in corso d'opera (io ho fatto le prime modifiche dopo 1 anno) Considerazioni sparse -2, 4 o 10 pasti non è rilevante -Il prework servirebbe se ti allenassi a digiuno (BCAA) -Il post work di solito è il pasto solido più abbondante ma nessuno vieta di fare un post wo nell'immediato dopo allenamento e poi fare il pasto solido successivamente -1650Kcal ??! ma è uno scherzo? ![]() -il 16-8 si basa sulla ciclizzazione delle Kcal nei giorni ON e OFF A seconda dell'ora in cui ti alleni scegli il template appropriato "Fasted training Training is initiated on an empty stomach and after ingestion of 10 g BCAA or similar amino acid mixture. This "pre-workout" meal is not counted towards the feeding phase. Technically, training is not completely fasted - that would be detrimental. The pre-workout protein intake, with its stimulatory effect on protein synthesis and metabolism, is a crucial compromise to optimize results. The 8-hour feeding phase starts with the post-workout meal. Sample setup 11.30-12 AM or 5-15 minutes pre-workout: 10 g BCAA 12-1 PM: Training 1 PM: Post-workout meal (largest meal of the day). 4 PM: Second meal. 9 PM: Last meal before the fast. Calories and carbs are tapered down throughout the day in the example above. Early morning fasted training Here's a sample setup for a client that trains early in the morning and prefers the feeding phase at noon or later. Read this for details regarding this protocol. 6 AM: 5-15 minutes pre-workout: 10 g BCAA. 6-7 AM: Training. 8 AM: 10 g BCAA. 10 AM: 10 g BCAA 12-1 PM: The "real" post-workout meal (largest meal of the day). Start of the 8 hour feeding-window. 8-9 PM: Last meal before the fast. For the sake of conveniency, I recommend getting BCAA in the form of powder and not tabs. Simply mix 30 g of BCAA powder in a shake and drink one third of it every other hour starting 5-15 minutes pre-workout. Tabs are cheaper, but much more of a hassle (you're going to have to pop a lot of tabs). Check my supplements guide for specific brand recommendations. One pre-workout meal This is the most common setup for my younger clients that are still in college or have flexible working hours. Sample setup 12-1 PM or around lunch/noon: Pre-workout meal. Approximately 20-25% of daily total calorie intake. 3-4 PM: Training should happen a few hours after the pre-workout meal. 4-5 PM: Post-workout meal (largest meal). 8-9 PM: Last meal before the fast. Two pre-workout meals This is the usual protocol for people with normal working hours. Sample setup 12-1 PM or around lunch/noon: Meal one. Approximately 20-25% of daily total calorie intake. 4-5 PM: Pre-workout meal. Roughly equal to the first meal. 8-9 PM: Post-workout meal (largest meal). Key points * No calories are to be ingested during the fasted phase, though coffee, calorie free sweeteners, diet soda and sugar free gum are ok (even though they might contain trace amount of calories). A tiny splash of milk in your coffee won’t affect anything either (½-1 teaspoon of milk per cup at the most - use sparingly and sensibly if you drink a lot of coffee). Neither will sugar free gum in moderation (~20 g). * The fast is the perfect time to be productive and get things done. Don’t sit around, get bored and brood about food. * Meal frequency during the feeding phase is irrelevant. However, most people, including me, prefer three meals. * The majority of your daily calorie intake is consumed in the post-workout period. Depending on setup, this means that approximately 95-99% (fasted training), 80% (one pre-workout meal) or 60% (two pre-workout meals) of your daily calorie intake is consumed after training. * The feeding window should be kept somewhat constant due to the hormonal entrainment of meal patterns. We tend to get hungry when we're used to eating and maintaining a regular pattern makes diet adherence easier. If you're used to breaking the fast at 12-2 PM and ending it at 8-10 PM, then try to maintain that pattern every day. * On rest days, meal one should ideally be the largest meal, as opposed to training days where the post-workout meal is the largest meal. A good rule of thumb is to make meal one on rest days at least 35-40% of your daily calorie intake. This meal should be very high in protein; some of my clients consume more than 100 g of protein in this meal. * When working with clients I am always open to compromising on the above rule. If your preference is to eat a larger meal in the evening instead of noon, or whenever you break the fast, it's no great harm. Some people prefer to save the largest meal on rest days for dinner with their family instead of having a large lunch and that's fine by me if it makes them enjoy and adhere to their diet better. * Macronutrients and calorie intakes are always cycled through the week. The specifics depends on the client's ultimate goal: fat loss, muscle gain or bodyrecomposition. The details will be revealed in the book. Generally speaking, carbs and total calorie intake is highest on training days. On rest days, carbs are lower and fat is higher. Protein is kept high on all days. * Here are the supplements I recommend everyone to take on a daily basis: a multivitamin, fish oil, vitamin D and extra calcium (unless dairy is consumed on a regular and daily basis). * For fasted training, BCAA or an essential amino acid mixture is highly recommended. However, if this feels like too much micromanaging or simply questionable from an economic standpoint, you could also make due with some whey protein. The importance of protein intake prior to fasted training is outlined in this and this post. * People sometimes ask me which protocol is best. I tend to look at things from a behavioral perspective first and foremost, so my reply to that is to choose the protocol best suited to your daily routine and training preferences. When dealing with clients I make the choice for them. If you work a 9-5 job and your only option is to train after work, training fasted is generally a bad idea and I always choose the one or two meals pre-workout protocol. * Even from a physiological perspective, each protocol has it's own strengths and theoretical benefits. With "physiological perspective" I mean in terms of nutrient partitioning, fat loss and muscle growth. This deserves an article on it's own. I have some interesting and compelling arguments that I think are very unique.

Finalmente trovo qualcuno che conosca il 16-8 in maniera (mi pare, e non credo di sbagliarmi) adeguata, il calcolatore mi sarà di grande aiuto. Per quanto riguarda le calorie, ho voluto partire (come scritto nel messaggio precedente) con il solito peso corporeo x 30 per poi alzare di settimana in settimana. Tu che formula mi consigli per calcolare il metabolismo basale? Nel calcolatore cita quella di "Mifflin-St Jeor [(10 × weight) + (6.25 × height) - (5 × age) + 5]" e quella di "Harris-Benedict [66 + (6.23 x weight in pounds) + (12.7 x height in inches) - (6.76 x age in years)]". Capitolo proteine: non vorrei diventare un fissato di questo macro tipo random bodybuilder, per adesso vorrei tenere il 20% per poi fare le mie valutazioni. Sbaglierò con la mia testa e vorrei avere la possibilità di imparare, adesso vorrei solamente mettermi a lavorare più presto possibile! Ti ringrazio di nuovo, buona serata ![]() |

Si, ok l'aumentare graduale ma partendo dal TDEE non dal basale Io uso (usavo) Mifflin-St Jeor ma in realtà, dopo un pò che stai a dieta,queste formule non servono a granchè (il TDEE lo devi sapere) Per le pro fai come credi ![]() |

Io un tentativo lo farei, non ho mai sentito di totali neofiti come me partire da un 16-8 o similari. Magari potrei scriverci qualcosa a riguardo. Quote:
Perdonami è un po' che cerco riferimenti alle proteine ma ho trovato solamente note sparse sui vari tipi di proteine e una ricetta di "pudding proteico" sul suo sito, riusciresti a linkarmi qualche trattato? Ho partecipato a qualche meeting inerente il consumo proteico e l'incidenza oncologica in rapporto al consumo di esse. Per un certo periodo ho pensato di diventare anche vegano sinceramente, credo sia questa mia "deformazione mentale" a volermi dire di "stare attento" con le proteine. |
