MikeG 2 months ago. For now, I'd like to use Carb Manager to track my fasting. Just that. I don't want to pick a schedule. I'd like my fasting to have some variability and I'd like to get reports on how I'm doing. I think I've been averaging 15 hours. But, I don't have a report to prove it.
I'd like to put in: Mon- Ate pm Stopped pm Tue- Ate am Stopped pm Then I'd like to get a report on how I did. I'm really interested in just the fasting report. I haven't seen how to do that in Carb Manager yet. I would love to have some help with that. Thanks Mike G. At some point I'll do a few days: like 1 or 2 or 3 or 5.
Before doing that, I'd like to have a good understanding of where I am first. Weew00 8 days ago. Someone more knowledgeable may replied to you, but if you just put in a food when you start eating and then put in a food when you stop eating, it will automatically measure the time between those.

| Alternate-Day Fasting: A Comprehensive Beginner's Guide | However, research agrees that modified ADF with calories on fasting days is much more tolerable than full fasts on fasting days One study comparing ADF to calorie restriction showed that ADF increased levels of brain-derived neurotrophic factor BDNF after 24 weeks of follow- up. Researchers concluded that ADF may induce long-term changes in BDNF and that this may promote improved weight loss maintenance. However, the researchers found that BDNF levels did not correlate with body weight changes in this particular study and suggested that these findings be interpreted with caution However, animal studies have shown that modified ADF resulted in decreased amounts of hunger hormones and increased amounts of satiety hormones compared to other diets 17 , 18 , Another factor to consider is compensatory hunger, which is a frequent downside of traditional, daily calorie restriction 20 , 21 , Compensatory hunger refers to increased levels of hunger in response to calorie restriction, which cause people to eat more than they need to when they finally allow themselves to eat. In fact, many people who try modified ADF claim that their hunger diminishes after the first 2 weeks or so. After a while, some find that the fasting days are nearly effortless 5. The effects of alternate-day fasting on hunger are inconsistent. Studies on modified alternate-day fasting show that hunger decreases as you adapt to the diet. Some studies have suggested that ADF may be more beneficial for preserving muscle mass than other types of calorie restriction,. However, results from a recent, high-quality study suggest that ADF is no more effective for preserving muscle mass than traditional calorie restriction 6 , 8 , 16 , 25 , Losing weight and restricting calories is usually an effective way to improve or reverse many symptoms of type 2 diabetes Similarly to continuous calorie restriction, ADF seems to cause mild reductions in risk factors for type 2 diabetes among people with overweight or obesity 30 , 31 , ADF may also help reduce fasting insulin levels, with some studies suggesting that it may be more effective than daily calorie restriction. However, not all studies agree that ADF is superior to daily calorie restriction 6 , 33 , 34 , Having high insulin levels, or hyperinsulinemia, has been linked to obesity and chronic diseases, such as heart disease and cancer 36 , A reduction in insulin levels and insulin resistance should lead to a significantly reduced risk of type 2 diabetes, especially when combined with weight loss. Alternate-day fasting may reduce risk factors for type 2 diabetes. It can reduce fasting insulin levels in people with prediabetes. Heart disease is the leading cause of death in the world and responsible for about one in four deaths 38 , 39 , Many studies have shown that ADF is a good option to help individuals with overweight or obesity lose weight and reduce heart disease risk factors 1 , 4 , 8 , The most common health benefits include 1 , 8 , 13 , 14 , 42 , 43 :. Alternate-day fasting may reduce waist circumference and decrease blood pressure, LDL bad cholesterol, and triglycerides. Autophagy is a process in which old parts of cells are degraded and recycled. It plays a key role in preventing diseases, including cancer, neurodegeneration, heart disease, and infections 44 , Animal studies have consistently shown that long- and short-term fasting increase autophagy and are linked to delayed aging and a reduced risk of tumors 46 , 47 , 48 , Furthermore, fasting has been shown to increase lifespan in rodents, flies, yeasts, and worms Moreover, cell studies have shown that fasting stimulates autophagy, resulting in effects that may help keep you healthy and live longer 51 , 52 , This has been supported by human studies showing that ADF diets reduce oxidative damage and promote changes that may be linked to longevity 9 , 15 , 52 , The findings look promising, but the effects of ADF on autophagy and longevity need to be studied more extensively. Alternate-day fasting stimulates autophagy in animal and cell studies. This process may slow aging and help prevent diseases like cancer and heart disease. Nearly all weight loss methods cause a slight drop in resting metabolic rate 55 , This effect is often referred to as starvation mode , but the technical term is adaptive thermogenesis.

A 3-week study analyzed individuals with average weight following a strict ADF diet with zero calories on fasting days. It showed that following an ADF diet for 12 weeks reduced fat mass and produced favorable changes in risk factors for heart disease 8. That said, ADF generally provides much fewer calories than you need to maintain weight, which is the reason you ultimately lose weight. Alternate-day fasting increases fat burning and reduces risk factors for heart disease in people with average weight. These will make you feel full without many calories. Soups may also be a good option on fasting days, as they tend to make you feel fuller than if you ate the ingredients on their own 57 , There are no strict guidelines regarding what to eat and drink on fasting days. Some think that ADF increases your risk of binge eating , but studies have found that it may help reduce binge eating behavior and decrease depressive symptoms. It may also improve restrictive eating and body image perception among people with obesity. However, more research on the effectiveness and safety of ADF in people with disordered eating tendencies is needed These include children, pregnant and lactating women, people who are underweight, and those with certain medical conditions that may be exacerbated by fasting like Gilbert Syndrome Although some research suggests that ADF may be helpful for reducing symptoms of binge eating, this dietary pattern is likely not appropriate for people with eating disorders, including anorexia nervosa or bulimia. Be sure to consult a healthcare provider before trying this eating pattern if you have a medical condition or are currently taking any medications. Alternate-day fasting is safe for most people. Research has shown dieters who are alternate-day fasting lose most of their weight as fat and lose just a few ounces of muscle. Researchers have concluded that alternate-day fasting is more effective than caloric restriction at improving metabolic disease markers in people most at risk of developing diabetes. However, in metabolically healthy adults with obesity, no significant difference was found in metabolic disease markers between subjects doing alternate-day fasting compared to caloric restriction. Studies report that alternate-day fasting decreases total cholesterol, low-density lipoprotein cholesterol LDL-C , triglycerides, and systolic and diastolic blood pressure. Researchers have also noted positive impacts on LDL-C particle size. Subjects who exercised while following an alternate-day fasting diet and subjects who did the diet alone had increased LDL particle size after 12 weeks of intervention. Fasting is something you choose to do, with a defined goal in mind, while starvation is an unfortunate situation due to conditions out of your control, such as war or famine. Hunger, irritability, constipation, bad breath, occasional sleep problems, dizziness, and weakness are the most common side effects. Reported symptoms are mild and often go away a couple of weeks after beginning alternate-day fasting. Furthermore, there was no evidence that thyroid function had been negatively affected in people doing long-term alternate-day fasting, even though some anecdotal reports suggest this may be an issue with frequent, extended fasting, especially for women.

The part of the weight loss conversation that gets left out is how to create a calorie deficit in a way that feels easier and is sustainable in the long term. Alternate-day fasting can do just that.
