Well, the most immediate side effect of excessive protein consumption is dehydration along with weight gain, constipation / diarrhoea or bad breathe. Long term side effect is usually on your kidneys and there are some other effects but those depend on your current health status ( i.e existing health concerns)
Next Steps
First check your height in centimetres. Subtract that with 100 and the answer is your ideal body weight.
E.g if someone’s height is 163 cm then 163-100= 63 which is the ideal body weight
Protein requirement for a sedentary adult is calculated as 0.8 multiplied by ideal body weight
E.g 0.8* 63 = 50.4gms daily protein intake
Health Tips
Try to consume protein from natural food sources
When consuming high protein diet ensure you drink at least 3 L of water daily
