QAYBTA 4: Sida Jidhku U Kaydiyo Baruurta — Lipogenesis, Lipolysis & Metabolism-ka Dufanka

 

Baruurta jirka kuma dhicin si lama filaan ah—waa natiijo ka dhalata habab bayooloji ah oo aad u nidaamsan. Jirku mar walba wuxuu ku guda jiraa hawlo isku dhafan oo go’aamiya haddii tamarta (kalooriyada) aad qaadato la isticmaalo, la kaydiyo ama la gubo.

Qaybtan, waxa aynu si qoto dheer ugu sharxeynaa sidee jidhka bani’aadamku u abuuraa baruur (lipogenesis), sidee u gubtaa baruurta (lipolysis) iyo sidee metabolism-ku u maamulaa labadan nidaam.
Fahamkani wuxuu kuu oggolaanayaa inaad ogaato sababta dadka qaarkood si fudud u cayilaan halka qaar kalena si fudud u gubaan dufanka.

🟩 1. Lipogenesis — Habka Jidhku U Abuuro Baruur

“Lipogenesis” waa habka jidhku u baddalo tamarta dheeraadka ah ee cuntada → dufan lagu kaydiyo unugyada adipose tissue.

H3: Marka ay dhacdo lipogenesis?

Lipogenesis ayaa dhacda marka:

• aad cuntid kalooriyo badan

• insulin-ku sareeyo

• aad fadhido waqti badan

• aad cunto carb badan

• aad cunto sonkor badan

• aad cunto cunto warshadaysan

H3: Sidee u shaqeysaa?

1. Waxaad cunaysaa carbohydrate →

2. Sonkorta dhiigga ayaa kor u kacaysa →

3. Jirkaaga (pancreas) wuxuu soo daayaa insulin →

4. Insulin-ku wuxuu yiraahdaa: “tamartaas badan dufan ka dhig!”

Insulin waa hormoonka ugu sarreeya ee dhaliya baruur cusub.

H3: Halka dufanku ugu horreeyo?

• Caloosha (gaar ahaan ragga)

• Bowdyaha & barida (gaar ahaan dumarka)

• Gacmaha

• Dhabarka hoose

Waxa go’aamiya: genetics, hormones, iyo hab-nololeedkaaga.

🟥 2. Lipolysis — Habka Jidhku U Gubo Baruurta

Lipolysis waa habka lidka ku ah lipogenesis. Waa markii jidhku jebiyo dufanka kaydsan si uu u isticmaalo tamar.

H3: Goorma ayuu jidhku gubaa dufanka (lipolysis)?

Jirkaaga wuxuu gubaa baruur marka:

• kalooriyadaadu ka yar tahay baahidaada

• insulin-ku hooseeyo

• aad soonto

• aad jimicsi samayso

• aad hurdo fiican hesho

• cortisol uu xasilloon yahay

• aad qabow la kulanto (brown fat activation)

H3: Sidee u dhacdaa lipolysis?

Unugyada baruurta (adipocytes) waxay jebiyaan dufanka si ay u sii daayaan:

• fatty acids

• glycerol

Kuwo ayaa u safra murqaha, kuwa kale waxay u socdaan beerka. Waxaas ayaa loo baddalaa tamar.

Waa habka ugu muhiimsan ee miisaanka dhabta ah lagu dhimo.

🟦 3. Metabolism-ka Dufanka — Sidee Jirku U Go’aamiyaa Inuu Kaydiyo Mise Uu Gubo?

Metabolism-ka (dheef-shiidka) waa ururinta dhammaan hawlaha jidhka ee gubista iyo kaydinta tamarta.
Jidhkaaga wuxuu ku jiraa laba xaaladood oo is beddelaya:

H2: 1. “Fed State” — Xaalad Jirku Tamarta Kaydiyo

Waa markaad wax cunto.
Jirkaagu wuxuu leeyahay:

• Insulin sare

• Gubid tamar oo hooseysa

• Kaydin baruur oo sarreeya

• Lipogenesis firfircoon

Tani waxay socotaa 2–4 saacadood cuntada ka dib.

---

H2: 2. “Fasted State” — Xaalad Jidhku Dufanka Gubo

Waa markaad dhowr saacadood wax cunin (6–12 saacadood).
Waxa dhacaya:

• Insulin hoos ayuu u dhacaa

• Glucagon kor ayuu u kacaa

• Jirkaagu wuxuu galaa lipolysis

• Baruurta ayaa la gubaa si loo helo tamar

Tani waxay yar tahay dadka wax cunaya maalin dhan oo aan waqti u ogolaan jidhkooda inuu galo lipolysis.

---

🟧 4. Sidee Jidhku U Dooranayaa Halka Dufanka La Dhigo?

Waxaa go’aamiya 3 arrimood oo waaweyn:

H3: 1. Genetics (Hiddo-side)

Haddii qoyskaaga baruurta caloosha ku keeno, adigana waxaad u badan tahay inay halkaa kugu ururto.

H3: 2. Hormoonnada

• Cortisol → caloosha

• Estrogen → bowdyaha

• Testosterone hoose → caloosha

• Insulin sare → dhammaan jidhka

H3: 3. Hab-Nololeedka & Dhaqdhaqaaqa

Fadhiga badan, cunto carb badan iyo hurdo la’aan waxay dedejiyaan kaydinta baruurta.

🟨 5. Brown Fat vs White Fat — Maxaa Metabolism-ka Ka Dhiga Mid Degdeg Ah?

Jirkaagu wuxuu leeyahay laba nooc oo dufan ah oo aad u saameeya metabolism-ka:

White Fat

• Waa baruurta kaydka ah

• Wuu kordhaa markaad badsato cunto

• Waa nooca ugu badan

Brown Fat

• Gubta tamarta

• Kordhiya metabolism

• Waxay ka shaqeysaa qabowga

• Aad bay u faa’iido u tahay miisaan dhimista

Haddii brown fat-kaaga kor u kaco → gubashada tamarta way korodhaa xataa marka aad fadhido.

---

🟫 6. Maxaa Ka Dhiga Inay Adkaato In Baruur La Dhimo?

Qaar ka mid ah sababahe ugu waaweyn waa:

• Insulin hormoonkiisa oo mar walba sare ah

• Cortisol sare (stress)

• Hurdo la’aan

• Murqo hoose → metabolism hoose

• Dhaqdhaqaaq la’aan

• Cunista sonkor & carb badan

• Baruur visceraal ah oo hore u jirtay

• Da’ sare

Jidhku wuxuu leedahay "fat memory” taasoo macnaheedu yahay in meel dufan hore ugu jirtay ay fududahay inay dib u buuxsanto.

📝 Gunaanad Qaybta 4

Qaybtan waxa aynu ku barannay:

• Baruur si bayooloji ah ayaa loo abuuraa (lipogenesis)

• Baruur si nidaamsan ayaa loo gubaa (lipolysis)

• Metabolism-ka ayaa go’aamiya dhinaca jidhku u jeedsado

• Hormoonno, genetics & qaab-nololeed ayaa go’aamiya halka baruurta lagu dhigo

• Brown fat wuxuu kordhiyaa gubashada tamarta

• White fat-na waa kayd tamareed

Fahamkani waxa uu muhiim u yahay si loo gubo dufanka si caqli iyo cilmiyaysan ah.
