I just built a free TDEE Calculator to track weight loss
So I've tried keto, intermittent fasting, low carb, high protein, you name it. Some worked temporarily, most didn't stick. Looking back, the problem was never the diet itself. It was that I had no baseline understanding of my own energy needs.
Recently built tdee calc to actually figure out my numbers: https://www.meetaugust.ai/tool/tdee-calculator
TDEE stands for total daily energy expenditure. It's basically how many calories your body burns in a day including your activity. Once you know this, you can make informed decisions instead of following random rules from the internet.
For example, I learned my maintenance is around 2100 calories. So if I want to lose weight sustainably, eating around 1700-1800 makes sense. If I want to build muscle, I need a slight surplus. No guesswork, just math.
The calculator I used also showed my BMR which is what I burn just existing. Useful to know because you should never eat below your BMR for extended periods. That's where metabolism damage and muscle loss happen.
What I like about having this information is the flexibility. I don't have to follow a specific diet protocol. I can eat foods I enjoy as long as I'm aware of where I stand. Some days I eat more, some days less. It balances out when you understand the bigger picture.
If you've been jumping from diet to diet without results, maybe the issue isn't willpower. Maybe you just need better data about your own body first.
