Lotus says that we should be keeping carbs at a low level.
But If I remember correctly Carbs/Sugars increase Insulin
Insulin is also responsible for fat storage
So Insulin + Cortisol = Belly Fat
and
Insulin + Oestro + Progesterone should = Increased boobage ?
Lotus - Could you please help us here ?
Visceral fat = DHT, in other words it's prevents boob growth. Protein, healthy fats, GH+IGF-1, IGF-2+3, E2, prolactin, progesterone, free testosterone, aromatase, dopamine, exercise produces breast growth. Imo you get the IGF naturally 2 ways, HIIT(high intense interval training) and intermittent fasting (12-14 hours, 3- days a week), supplements can help like MSM and L-arginine, L-Dopa , L-tyrosine.
Vitamin D helps increase IGF-1(insulin growth like factor), without IGF you can forget about breast growth, cuase you'll only get minuscule results.
IGF-=sleep (stage 3 & 4)
Protein (high intensity)
Exercise
Insulin-like growth factor I is essential for terminal end bud formation and ductal morphogenesis during mammary development.
Abstract
Previous studies from this laboratory have emphasized the essential role of GH in pubertal mammary development and shown that insulin-like growth factor I (IGF-I) was capable of substituting for GH in this process in rats and mice. The present study shows that, even when GH is present, no mammary development is possible unless IGF-I is present. IGF-I(-/-) null female animals were found to have significantly less mammary development than age matched wild-type controls (P <0.006) using several endpoints including the number of terminal end buds or TEBs (1.3 vs. 7.3), percent of the fat pad occupied by glandular elements (6.5 vs. 100), and number of ducts (15 vs. too numerous to count). That the deficiency in mammary gland development was related to the absence of IGF-I was underscored by the observation that des (1-3) IGF-I administration to IGF-I(-/-) null animals for 5 days caused significant mammary gland development as measured by TEB formation and branching of ducts. The number of TEBs rose from a mean of 1.3 in controls to 20.5 without added E2 (P < 0.009), and from 1.7 to 21 when des (1-3) IGF-I was given together with E2 (P < 0.006). The number of ducts increased significantly from a mean of 12 to 27 in response to IGF-I and E2, and from 15 to 24.5 with IGF-I alone. In contrast, administration of human GH with E2 had no stimulatory effect on mammary development in these animals, indicating that the full effect of GH in this process is mediated by IGF-I. To determine whether IGF-I was also responsible for further ductal morphogenesis, we administered des (1-3) IGF-I + E2 to the knockout animals for 14 days and compared the effects of this combination of hormones on mammary development with those observed after 5 days. We found that there was a significant increase from 5 to 14 days in the number of TEBs (mean: 21 vs. 41) and the area of the mammary fat pad occupied by glands (mean: 10 vs. 20%). There was elongation and thickening of the ducts which accounted for the increased area that was occupied by ductal structures. There was no significant increase in the number of ducts. However, there was the appearance of a large number of buds along the length of the ductal structures, suggesting the beginning of side branching. These results suggest that IGF-I, when given along with E2, is responsible for ductal morphogenesis.

Abstract
Pubertal mammary development in the rat is largely dependent upon GH and estrogen. We recently showed that insulin-like growth factor-I (IGF-I) can substitute for GH in inducing mammary development in male rats, suggesting that IGF-I mediates GH action. The present study investigated whether IGF-I, like GH, required estradiol (E2) to act or whether IGF-I could substitute for both GH and E2. The effects of IGF-I were tested in the presence and absence of E2. Elvax pellets containing IGF-I or des(1-3) IGF-I were implanted into right lumbar mammary glands of sexually immature, hypophysectomized, oophorectomized female rats, with control BSA-containing pellets in the contralateral glands. After 5 days, both lumbar mammary glands were removed and examined in whole mounts for mammary development by counting terminal end buds and alveolar structures. E2, administered in SILASTIC brand capsules, had no independent effect on mammary development. In the absence of E2, des(1-3) IGF-I had a small, but significant, independent effect on mammary development; native IGF-I was ineffective. The addition of E2 significantly enhanced the effects of IGF-I and des(1-3) IGF-I on mammary development, similar to that noted when E2 was given along with GH. We also studied the effects of E2 and/or hGH on mammary gland IGF-I messenger RNA (mRNA) in hypophysectomized castrated male animals. E2 alone did not increase mammary gland IGF-I mRNA concentrations, but E2 enhanced the effect of hGH on IGF-I mRNA by 4- to 6-fold. These studies indicate that IGF-I can have a small independent effect on mammary development, but like GH, E2 is required for a full effect. They also indicate that E2 is capable of synergizing with GH in the production or expression of IGF-I mRNA, and that the action of E2 on mammary development may take place at multiple sites. If locally produced IGF-I does indeed mediate the action of GH in mammary development, then although E2 is capable of enhancing the effect of GH on IGF-I mRNA, its major effect in mammary development occurs after IGF-I is produced.
