Omad definitely got easier as the weeks went by. That first week was very difficult, then second week had good and hard days. By the 3rd week, the tough days were less.

Nothing bad. Read this article on metabolism myths for more info.A diet with less meal frequency can improve the health and extend the lifespan of laboratory animals, but its effect on humans has never been tested.
A pilot study was conducted to establish the effects of a reduced-meal-frequency diet on health indicators in healthy, normal-weight adults. The study was a randomized crossover design with two 8-wk treatment periods. Subjects who completed the study maintained their body weight within 2 kg of their initial weight throughout the 6-mo period. There were no significant effects of meal frequency on heart rate, body temperature, or most of the blood variables measured.
When meal frequency is decreased without a reduction in overall calorie intake, modest changes occur in body composition, some cardiovascular disease risk factors, and hematologic variables. Diurnal variations may affect outcomes. Overeating is a major cause of morbidity and mortality in humans, and, accordingly, caloric restriction has multiple health benefits for the obese 12.
Caloric restriction may also improve the health of persons who are not considered overweight 3. Whereas nutrient-dense, low-calorie diets have numerous health benefits, the influence of meal frequency on health has not been established. However, studies of various laboratory animals 4 — 6 and specifically of rodents 57 — 9 have shown that dietary restriction caloric restriction or intermittent fasting—long-term intermittent fasting in the case of rodents can increase lifespan and protect against or suppress disease processes responsible for cardiovascular disease CVDcancer, diabetes, and neurodegenerative disorders.
The latter studies 57 — 9 showed beneficial effects of intermittent fasting on blood pressure, glucose metabolism, and vulnerability of cardiac and brain cells to injury. This knowledge gap has been identified by the Dietary Guidelines Advisory Committee Report as a future research direction 10 Studies of rodents and monkeys have led to several hypotheses concerning the cellular and molecular mechanisms whereby dietary restriction extends lifespan and protects against disease.
The oxidative stress hypothesis proposes that aging and age-related diseases result from cumulative oxidative damage to proteins, lipids, and nucleic acids; by decreasing the amount of oxyradicals produced in mitochondria, dietary restriction retards aging and disease A second hypothesis is that dietary restriction is beneficial primarily because of its effects on energy metabolism; ie, it increases insulin sensitivity Several physiologic variables have been shown to change in animals maintained on caloric restriction or intermittent fasting regimens or bothincluding decreased plasma insulin and glucose concentrations, decreased blood pressure and heart rate, and enhanced immune function 814 — The current pilot study was conducted to determine the feasibility of controlled meal frequency in normal-weight, middle-aged men and women.
Several physiologic outcomes and biomarkers of health were also investigated. Healthy men and women aged 40—50 y were recruited by newspaper advertisement from the greater Washington, DC, metropolitan area.
Subjects were excluded if they reported tobacco use, recent pregnancy or lactation, history of CVD or medication use for CVD, hypertension, diabetes, psychiatric condition, cancer, or employment in high-risk occupations this last exclusion criterion was due to the potential for dizziness or weakness during the meal-skipping phase.
