Protein Calculator for Weight Loss After 35

This is well above the RDA of 0.8 g/kg, which was set to prevent deficiency, not to protect muscle during a calorie deficit at midlife.

Protein target: grams/day = weight(kg) x 1.2 to 1.6 (dieting) or 1.6 to 2.0 (dieting + training) (PROT-AGE study group recommendations)

Two forces work against your muscle at midlife: anabolic resistance (older muscle responds less to small protein doses) and the calorie deficit itself (dieting bodies burn muscle unless given a reason not to). Research on dieting adults consistently shows higher protein intakes preserve significantly more lean mass at the same calorie deficit.

Muscle is also the engine behind your TDEE. Losing 20 lb where 6 of it is muscle leaves you with a slower metabolism and a softer look; losing 20 lb of nearly pure fat is a different outcome entirely, and protein plus strength training is what makes the difference.

Distribution beats heroics: 25 to 35 g per meal, 3 to 4 times per day, works better than one 80 g dinner because older muscle needs a meaningful dose at each sitting to trigger muscle protein synthesis.

Practical anchors: a palm-size chicken breast is about 31 g, a cup of Greek yogurt 17 g, two eggs 12 g, a scoop of whey 24 g, a cup of cooked lentils 18 g. Build each meal around one anchor and the daily total takes care of itself.

1.2 to 1.6 g per kg of body weight per day while dieting (0.55 to 0.73 g per lb). A 160 lb woman needs 87 to 116 g. Add strength training and the useful range extends to 2.0 g/kg.

In people with healthy kidneys, intakes up to 2.0 g/kg have not shown harm in controlled studies. If you have kidney disease, protein targets are a medical decision for your doctor.

Yes: Greek yogurt, eggs, cottage cheese, tofu, tempeh, lentils, edamame and whey or plant protein powders all work. Plant-based eaters should aim at the top of the range since plant proteins are less anabolic per gram.

Indirectly but powerfully: it preserves the lean mass that keeps your metabolism up, and it is the most satiating macronutrient, which makes a calorie deficit easier to live with.
