To lose weight does not need to cost a fortune, it can be done for free

Dear Editor

Semaglutide for weight loss is highly expensive. You can lose weight for free by ensuring that the kilocalories you consume are less than those you expend every day. I have described how this can be done and have provided a spreadsheet for the calculations that also makes it easy to see if you make progress according to you plan, as there is a regression line in it. It is freely available (1).

I decided to drop 6.5 kg in three months, which is a rate of weight loss that can relatively easily be endured, and have just accomplished that. All you need apart from the spreadsheet is determination.
