Here are some of the PROS of IF:
- Decreases body weight--this is partly due to caloric restriction
- Increases insulin levels--this is due to lower blood sugar levels which causes the pancreas to reduce its insulin release
- Increases human growth hormone (HGH) levels--increased HGH is released from the pituitary gland to allow the body to use more fat for energy
- Decreases risk of diseases--this is partly due to hormone changes lessening the onset of diseases like cancer and heart disease
- Improves cholesterol levels--LDL and HDL levels tend to decrease and increase, respectively
- Decreases blood pressure--this is due to a decrease in resting metabolic rate
Here are some of the CONS of IF:
- Catabolism--this occurs when muscle, which is a much more metabolically active tissue than fat, is broken down for needed energy when caloric intake has been reduced.
- Hypoglycemia--this involves low blood sugar levels which causes symptoms of hunger, headaches, weakness, and irritable feelings
- Bulging full feeling--caused by eating a relatively large amount of food within a short period of time
- Lethargy--this is caused by a lack of energy (read: calories) needed to fuel mental and physical activities
- Reduces Metabolic Rate--this is partly due to elevated cortisol, a stress hormone
- increased metabolic rate
- balanced blood sugar level
- muscle mass maintenance
- decreased bodyfat
My recommendation: "Listen" to the hormonal signals provided by your body which indicate hunger and eat. There are easier ways to lose body weight without causing dramatic fluctuations in blood sugar levels. Gradually reduce your caloric consumption while stepping up your physical activity. Eating healthy and exercising regularly will lessen disease risk, improve cholesterol levels, and reduce hypertension without resorting to a trendy diet like intermittent fasting.
