Background: Alternate-day fasting (ADF) involves a ‘famine day’ (25% energy intake) and a ‘feast day’ (ad libitum intake). This secondary analysis examined changes in beverage intake in relation to energy intake and body weight during 12 months of ADF versus daily calorie restriction (CR). Methods: Obese subjects ( n = 100 enrolled, n = 69 completers) were randomized to one of three groups for 12 months: (a) ADF; (b) CR; or (c) control. Results: At baseline, intakes of diet soda, caffeinated beverages, sugar-sweetened soda, alcohol, juice, and milk were similar between groups. There were no statistically significant changes in the intake of these beverages by month 6 or 12 between ADF (feast or famine day), CR, or control groups. Beverage intake was not related to energy intake or body weight at month 6 or 12 in any group. Conclusion: These pilot findings suggest that intermittent fasting does not impact beverage intake in a way that affects energy intake or body weight.

This study compared the weight loss efficacy of alternate-day fasting (ADF) versus daily calorie restriction (CR) in adults with subclinical hypothyroidism. After 6 months, body weight decreased (P < 0.001) similarly by ADF (–7% ± 1%) and CR (–8% ± 2%). Insulin resistance decreased (P < 0.05) more by ADF versus CR. Free thyroxin and thyroid-stimulating hormone remained unchanged. Thus, ADF and CR produce similar weight loss in this population, without affecting thyroid hormone levels. Novelty Intermittent fasting and daily restriction produce similar reductions in body weight in subjects with subclinical hypothyroidism.

Dietary regulation of appetite may contribute to the prevention and management of excess body weight. The present study examined the effect of consumption of individual dairy products as snacks on appetite and subsequent ad libitum lunch energy intake. In a randomised cross-over trial, forty overweight men (age 32 (sd 9) years; BMI 27 (sd 2) kg/m2) attended four sessions 1 week apart and received three isoenergetic (841 kJ) and isovolumetric (410 ml) servings of dairy snacks or water (control) 120 min after breakfast. Appetite profile was determined throughout the morning and ad libitum energy intake was assessed 90 min after the intake of snacks. Concentrations of amino acids, glucose, insulin, ghrelin and peptide tyrosine tyrosine were measured at baseline (0 min) and 80 min after the intake of snacks. Although the results showed that yogurt had the greatest suppressive effect on appetite, this could be confounded by the poor sensory ratings of yogurt. Hunger rating was 8, 10 and 24 % (P < 0·001) lower after the intake of yogurt than cheese, milk and water, respectively. Energy intake was 11, 9 and 12 % (P < 0·02) lower after the intake of yogurt, cheese and milk, respectively, compared with water (4312 (se 226) kJ). Although there was no difference in the postprandial responses of hormones, alanine and isoleucine concentrations were higher after the intake of yogurt than cheese and milk (P < 0·05). In conclusion, all dairy snacks reduced appetite and lunch intake compared with water. Yogurt had the greatest effect on suppressing subjective appetite ratings, but did not affect subsequent food intake compared with milk or cheese.

Sugar-sweetened beverage (sugar-SB) consumption is associated with body weight gain. We investigated whether the changes of (Δ) circulating leptin contribute to weight gain and ad libitum food intake in young adults consuming sugar-SB for two weeks. In a parallel, double-blinded, intervention study, participants (n = 131; BMI 18–35 kg/m2; 18–40 years) consumed three beverages/day containing aspartame or 25% energy requirement as glucose, fructose, high fructose corn syrup (HFCS) or sucrose (n = 23–28/group). Body weight, ad libitum food intake and 24-h leptin area under the curve (AUC) were assessed at Week 0 and at the end of Week 2. The Δbody weight was not different among groups (p = 0.092), but the increases in subjects consuming HFCS- (p = 0.0008) and glucose-SB (p = 0.018) were significant compared with Week 0. Subjects consuming sucrose- (+14%, p < 0.0015), fructose- (+9%, p = 0.015) and HFCS-SB (+8%, p = 0.017) increased energy intake during the ad libitum food intake trial compared with subjects consuming aspartame-SB (−4%, p = 0.0037, effect of SB). Fructose-SB decreased (−14 ng/mL × 24 h, p = 0.0006) and sucrose-SB increased (+25 ng/mL × 24 h, p = 0.025 vs. Week 0; p = 0.0008 vs. fructose-SB) 24-h leptin AUC. The Δad libitum food intake and Δbody weight were not influenced by circulating leptin in young adults consuming sugar-SB for 2 weeks. Studies are needed to determine the mechanisms mediating increased energy intake in subjects consuming sugar-SB.

Experiment 1: Over a 2-yr period, a total of 231 Angus crossbred cows were assigned randomly to one of three gestation diets to evaluate the effects of fat sources on birth weight, weaning weight and average daily gain of calves, calf condition at birth, calf mortality, body weight of cows, gestation length, calving percentage, and the percentages of retained placenta and dystocia. Isonitrogenous and isoenergetic supplements were based on whole flaxseed (FLA), calcium salts of palm oil (Megalac®, MEG) or no fat (CON). All cows were fed grass silage (90% of ad libitum intake) until 1 mo before calving. Cows were then fed grass silage for ad libitum intake until they were put on pasture. Cows were offered 600 g of supplement per head per day starting 43 d before the first calving for a period averaging 78 d. Diet had no effect on body weight (BW) of cows at calving. Birth weights of calves were similar among treatments. However, calf mortality percentage at birth was almost four times higher (P = 0.03) for cows fed CON compared with those fed FLA and MEG. More than 90% of cows rejected placenta within 12 h of calving and treatment had no effect. Cows fed FLA and CON tended (P ≤ 0.10) to have higher cumulative pregnancy rates (92.9 and 91.9%, respectively) than those fed MEG (76.7%). Experiment 2: From 2000 Jan. 19 to 2000 Sep. 05, 41 heifers received 600 g per head per day of one of the three supplements used in exp. 1 to determine the effect of fat supplementation during pregnancy and breeding. Diet had no effect on calf birth weight, but contrasts indicated that heifers fed MEG tended (P = 0.09) to have a lower pregnancy rate than those fed CON. These data suggest that cows and heifers fed grass silage and/or on pasture would not be deficient in omega 3 fatty acids, thus would not benefit from a supplement rich in omega 3 fatty acids such as flaxseed. However, fat supplementation contributed to lower calf mortality at birth in cows, but not in heifers. Key words: Beef, flaxseed, reproduction, fatty acids

Abstract Objectives Intermittent fasting (IF) is a popular trending diet, yet there is limited evidence-based support considering its clinical impact on cardiometabolic outcomes. In an effort to inform the European Association for the Study of Diabetes (EASD) clinical practice guidelines for nutrition therapy, we conducted a network meta-analysis of randomized controlled trials (RCTs) comparing IF strategies and continuous energy restriction (CER) on cardiometabolic outcomes using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. Methods MEDLINE, EMBASE, and Cochrane databases were searched through Nov 2020. We included RCTs assessing the effect of IF strategies (alternate-day fasting (ADF), whole-day periodic fasting (WDF), time-restricted feeding (TRF)), CER, and ad libitum diet. Outcomes included body weight, fasting glucose and LDL-cholesterol. Two independent researchers extracted data and assessed risk of bias. A network meta-analysis was performed and data were expressed as mean differences (MD) with 95% confidence intervals (CI). The certainty of the evidence was assessed using GRADE. Results We identified 19 RCTs (n = 590) including adults of varying health backgrounds. ADF and CER both showed a benefit for body weight reduction compared to ad libitum diet (18 trials, n = 520; MD −3.95 kg [95% CI −6.09, −1.81] and MD −2.85 kg [95% CI −4.99, −0.71], respectively). For fasting glucose (17 trials, n = 590), TRF showed a benefit compared to ad libitum diet (MD −0.39 mmol/L [95% CI −0.59, −0.20]), to CER (MD −0.25 mmol/L [95% CI, −0.45 to −0.06]) and to WDF (MD −0.20 mmol/L [95% CI, −0.45, −0.05]). Furthermore, ADF showed a benefit in reducing LDL-cholesterol (17 trials, n = 590) compared to ad libitum diet (MD −0.21 mmol/L [95% CI −0.40, −0.1]), and to CER (MD −0.15 mmol/L [95% CI −0.31, −0.01]). The certainty of the evidence ranged from high to moderate due to variable downgrades for imprecision. Conclusions Current evidence provides a good indication that IF strategies have similar benefits to CER for weight loss but may have additional benefits for fasting glucose and LDL-cholesterol. Long-term high quality RCTs are needed to clarify the effect of different IF strategies on cardiometabolic outcomes.

The Impact

This mini-review summarizes the available information regarding the impact of caloric restriction (CR) and/or intermittent fasting (IF) on bone health. CR and IF are dietary interventions used in rehabilitative healthcare for augmenting weight loss and also proposed for recovery of conditions such as stroke and heart failure. CR restricts the total number of calories rather than different food groups or periods of eating. In contrast, IF severely restricts caloric intake for a period of time followed by a period of ad libitum intake. Here, we discuss the available information regarding the impact of these rehabilitation diets on bone metabolism, highlighting areas of consistency and discrepancy and suggesting future areas of study to advance the understanding of CR and/or IF on bone health.

Forty crossbred lambs (20 rams, 20 ewes) were penned in two groups (equal numbers of each sex) and fed a pelleted ration either ad libitum (H) or 70% of expected ad libitum intake (70% H). Ten lambs (5 rams, 5 ewes) from both groups (H and 70% H) were slaughtered after 40 days on feed while the remaining lambs were slaughtered after 61 days on feed. All lambs were measured for carcass leanness using an EMME machine immediately prior to slaughter. The offal components were weighed fresh and the alimentary tract was emptied of digesta. One side of each carcass was broken into four cuts (leg, loin, rib, shoulder) which were further separated into fat, muscle and bone. EMME numbers only marginally increased the amount of explained variation in the prediction of lean weight over that provided by liveweight alone. Growth coefficients between sexes and intake groups (H, 70% H) for the offal components relative to empty body weight were homogeneous, indicating that sex and dietary energy intake did not affect the relative growth of the offal components. Ram lambs had heavier heads and smaller intestines than ewe lambs, but contained less caul and mesenteric fat than ewe lambs at the same empty body weight. Lambs fed H had a greater weight of pelt, liver and caul fat, but had a lower warm carcass weight and less mesenteric fat than lambs fed 70% H at the same empty body weight. Growth coefficients between sexes and intake groups for the carcass tissues relative to physically separated tissue weights (muscle, bone, fat) were homogeneous, which indicated that sex and intake did not affect the relative growth of the carcass tissues. Ram lamb carcasses had a greater weight of muscle in the shoulder and less muscle in the leg than ewe lamb carcasses at the same carcass muscle weight. Dietary energy intake had small but statistically significant effects on carcass muscle distribution. Lambs fed 70% H produced carcasses with proportionally more muscle in the leg and less muscle in the loin and shoulder than lambs fed H at the same carcass muscle weight. Sex and dietary energy intake had minor effects on carcass bone and fat distribution. Key words: Lambs, carcass, offal, fat, EMME

ABSTRACT: This study aimed to evaluate the effects of feed restriction on the carcass characteristics of castrated Canindé goat kids. A randomized block design was used, in which 21 goat kids with a body weight (BW) of 15.9±1.0kg were allocated to three levels of feed restriction: ad libitum, 20% and 40% restriction related to the ad libitum intake. The diet consisted of 55% forage (Tifton) and 45% concentrate. All animals were slaughtered when the kids fed ad libitum reached a BW of 25kg. After slaughter, the carcasses were chilled for 24 hours and subsequently measured. Kids fed ad libitum and subjected to 20% feed restriction showed similar morphometric carcass measurements, except for the chest circumference. Goat kids fed ad libitum exhibited greater values for warm and cold carcass yields compared with those subjected to 40% feed restriction and did not differ from the kids under 20% feed restriction. Weights of the commercial cuts showed decreasing mean values according to the intensity of feed restriction. Castrated Canindé goat kids subjected to 20% feed restriction presented similar carcass yields and proportion of commercial cuts to those fed ad libitum.

Angiopoietin-like 2 (ANGPTL2) is an inflammatory adipokine linking obesity to insulin resistance. Intermittent fasting, on the other hand, is a lifestyle intervention able to prevent obesity and diabetes but difficult to implement and maintain. Our objectives were to characterize a link between ANGPTL2 and intermittent fasting and to investigate whether the knockdown of ANGPTL2 reproduces the benefits of intermittent fasting on weight gain and insulin responsiveness in knockdown and wild-type littermates mice. Intermittent fasting, access to food ad libitum once every other day, was initiated at the age of three months and maintained for four months. Intermittent fasting decreased by 63% (p < 0.05) gene expression of angptl2 in adipose tissue of wild-type mice. As expected, intermittent fasting improved insulin sensitivity (p < 0.05) and limited weight gain (p < 0.05) in wild-type mice. Knockdown mice fed ad libitum, however, were comparable to wild-type mice following the intermittent fasting regimen: insulin sensitivity and weight gain were identical, while intermittent fasting had no additional impact on these parameters in knockdown mice. Energy intake was similar between both wild-type fed intermittent fasting and ANGPTL2 knockdown mice fed ad libitum, suggesting that intermittent fasting and knockdown of ANGPTL2 equally lower feeding efficiency. These results suggest that the reduction of ANGPTL2 could be a useful and promising strategy to prevent obesity and insulin resistance, although further investigation of the mechanisms linking ANGPTL2 and intermittent fasting is warranted. Impact statement Intermittent fasting is an efficient diet pattern to prevent weight gain and improve insulin sensitivity. It is, however, a difficult regimen to follow and compliance is expected to be very low. In this work, we demonstrate that knockdown of ANGPTL2 in mice fed ad libitum mimics the beneficial effects of intermittent fasting on weight gain and insulin sensitivity in wild-type mice. ANGPTL2 is a cytokine positively associated with fat mass in humans, which inactivation in mice improves resistance to a high-fat metabolic challenge. This study provides a novel pathway by which IF acts to limit obesity despite equivalent energy intake. The development of a pharmacological ANGPTL2 antagonist could provide an efficient tool to reduce the burden of obesity.
